水泥中控操作培训讲义

绪 言

?

水泥是建筑工业三大基本材料之一,使用广、用量大、 素有“建筑工业的粮食”之称。生产水泥虽需要较多的能源,但水泥与砂、石等材料的混泥 土是一种低能耗新型建筑材料。例如,在相同荷载的条件下,混泥土柱的耗能量仅为钢柱的 1/5-1/6,砖柱的 1/4。根据预测,在未来的几十年内,水泥依旧是主要建筑材料。水泥具有较好 的可塑性,与砂、石等胶合后的混和物具有较好的和易性,可浇注成多种形状及尺寸的构件, 以满足设计上的不同要求;水泥的适应性较强,适用于海上、地下、深水、严寒、干热、腐蚀、 辐射等多种条件下;水泥还可与多种有机、无机材料制成多种用途的水泥复合材料;水泥耐久 性较好,维修工作量小,不易生锈、耐腐朽。目前,水泥已广泛用于建筑、水利、道路、国防 等工程中。近年来,宇航、信息及其它新兴工业中对各种具有特种性能的水泥复合材料的需求 也越来越大。因此,水泥工业在整个国民经济中起着十分重要的作用。在目前甚至未来相当长 的时期内,水泥仍将是人类社会的主要的建筑材料。

水泥基础知识

? ?

第一节 基本概念 一、胶凝材料 在物理化学作用下,能从浆体变成坚固的石状体,并能胶结其它物料而有一定机械 强度的物质,统称为胶凝材料。它分为无机和有机两大类。无机胶凝材料又按照硬化条件,又 可分为水硬性和非水硬性两种。水硬性胶凝材料指在拌水后既能在空气中又能在水中硬化的材 料,如水泥。非水硬性胶凝材料不能在水中硬化,而只能在空气中硬化,故称为气硬性胶凝材 料,如石灰、石膏等。

?

二、水泥 广义上说,水泥泛指一切能够硬化的无机胶凝材料;而狭义的水泥则专指现代水 泥,即具有水硬性的胶凝材料。

? ?

三、水泥的品种和分类 对水泥的分类通常有两种方法:一是按用途及性能分类,二是按其主要水硬性物质名称分 类。 ? 1、按水泥用途分为:通用水泥、专用水泥、特性水泥三大类。 ? 通用水泥:是指适用于大多数工业、民用建筑工程的硅酸盐系列品种水泥。主要有硅酸盐 水泥,普通硅酸盐水泥、矿渣硅酸盐水泥、火山灰质硅酸盐水泥、粉煤灰硅酸盐水泥以及复合 硅酸盐水泥。 ? 专用水泥:是指有专门用途的水泥,如油井水泥、中热硅酸盐水泥和粉煤灰硅酸盐水泥等。

?

特性水泥:是指某种性能较突出的一类水泥。 如快硬水泥系列、膨胀水泥系列、抗硫酸盐硅酸盐水泥等。 ? 专用特种水泥包括:快硬高强水泥、膨胀水泥、自应力水泥、水工水泥、油井水泥、装饰 水泥、砌筑水泥、低碱水泥、道路水泥等种类。

1、硅酸盐水泥熟料:凡适当成分的生料烧至部分熔融,所得以硅酸钙为主要成分的产 物称为硅酸盐水泥熟料(简称熟料) 。 2、石膏:包括天然石膏和工业副产石膏、质量必须符合标准。 3、活性混合材:系指具有火山灰性或潜在水硬性的混合材料。如高炉矿渣、火山灰和 粉煤灰。 制造水泥的组分材料

4、非活性混合材:系指活性指标不符合标准要求的潜在水硬性或火山灰的水泥混合材 料,以及砂岩和石灰石。 5、窑灰:从水泥回转窑窑尾废气中收集下的粉尘。 6、助磨剂:水泥粉磨时允许加入起助磨作用而不损害水泥性能的助磨剂。其加入量不 得超过水泥质量的 1%。 二、硅酸盐水泥的标号 国家标准中把硅酸盐水泥的标号设置为 325、325R;425、425R;525、525R;625、625R; 725、725R 几等。标号是根据水泥 28D 抗压强值确定的。 三、硅酸盐水泥的技术指标(品质指标) ? 1、化学指标:是保证水泥质量和性能的重要依据 ? (1)氧化镁含量:在水泥熟料中,常含有少量与其他矿物结合的游离氧化镁,它是高 温时形成的方镁石,它水化为氢氧化镁的速度很慢,常在水泥硬化以后才开始水化,在水化时 产生体积膨胀,可导致水泥石结构产生裂缝甚至破坏,因此,它是引起水泥安定性不良的原因 之一。 ? 因此,国家标准(GB175-1999)规定,水泥中氧化镁的含量不得超过 5%。如果水泥 经压蒸安定性试验合格,则水泥中氧化镁的含量允许放宽到 6%。

?

(2)三氧化硫含量:水泥中的 S03 主要是在生产时为调节凝结时间加入石膏而带来的,也 可能是煅烧熟料时加入石膏矿化剂而带入熟料的。适量石膏虽能改善水泥性能(如提高水泥强 度、降低收缩性、改善抗冻耐蚀和抗渗性等) ,但石膏超过一定含量后,水泥性能会变差,甚至 引起硬化水泥石膨胀,导致结构破坏。因此水泥中 S03 的含量必须加以限制。

? ? ? ? ? ? ? ?

现行国家标准规定,水泥中 S03 的含量不得超过 3.5%。

(3)烧失量:水泥煅烧不佳或受潮后,均会导致烧失量增加。烧失量测定是以水泥试样在 950-1000℃下灼烧 15-20min,冷至室温称量。如此反复灼烧直至恒重,按下式计算烧失量:X? =(mo-m1)/mo×100 式中:X?——烧失量% mo——灼烧前试样质量 g m1——灼烧后试样质量 g

普通水泥、矿渣水泥中的烧失量,回转窑厂不得大于 5%,立窑大不得大于 7%。 硅酸盐水泥的技术指标(品质指标) 2、物理指标 (1)细度:水泥细度是表示水泥磨细后的程度或水泥分散度的指标。它对水泥的水化 硬化速度、水泥需水量、和易性、放热速率及强度都有影响。水泥细度可用筛析法和比表面积 法表示。现行标准规定,普通水泥、矿渣水泥、火山灰水泥和粉煤灰水泥,在 0.08mm 方孔筛 上筛余量不得超过 10%;硅酸盐水泥细度不少于 300 ㎝ 2/g。

(2)凝结时间:是指水泥从加水开始,到水泥浆失去可塑性所需的时间。凝结时间分为初 凝时间和终凝时间。 初凝时间是从水泥加水开始到水泥浆失去可塑性所需的时间;终凝时间是从水泥加水 开始到水泥浆完全失去塑性的时间。我国标准规定,采用凝结时间测定仪来测定。标准规定, 硅酸盐水泥初凝时间不得早于 45 分钟,终凝时间不得迟于 390 分钟(6.5 小时) ;普通硅酸盐水 泥初凝时间不得早于 45 分钟,终凝时间不得迟于 10 小时。

? ?

(3)安定性:安定性是指水泥在凝结硬化过程中体积变化的均匀性。

水泥与水拌制成的水泥浆体,在凝结硬化过程中,一般都会发生体积变化。如果这种 体积变化是在凝结硬化过程中,则对建筑的质量并没有什么影响。但是如果混凝土硬化后,由 于水泥中某些有害成分的作用,在水泥石内部产了剧烈的、不均匀的体积变化时,在建筑物内 部产生破坏应力,导致建设物强度降低,甚至会引起建筑物开裂,崩塌等严重事故。

?

水泥体积安定性不良的原因在于:水泥熟料中游离 Cao、MgO 含量过多或掺入的石膏含量 过多。熟料中的游离 CaO、MgO 经过高温煅烧后均呈“过烧”状态,水化十分缓慢。在水泥已经 硬化后才进行水化,体积膨胀,引起不均匀的体积变化,使水泥石开裂。石膏含量过多时,在 水泥硬化后,它还会与固体的水化铝酸钙反应,生成高硫型水化硫铝酸钙,体积约增大 1.5 倍, 引起水泥石开裂。

? ? ? ? ? ? ?

安定性的检验方法: ①沸煮法: (不常用)主要用来检验由游离 CaO 引起的体积变化。 ②试饼法。 ③雷氏法: 用雷氏夹测定, 试件两指针尖端距离增加的平均值≤5mm 时, 安定性合格。 ④压蒸法:主要用来检验由游离 MgO 引起的体积变化。 (4)强度:强度是水泥技术中最基本的指标,它直接反映了水泥的质量水平和使用价 值。国际上都采用砂浆法作为水泥强度的标准检验方法。我国亦采用水泥胶砂来评定水泥强度。 我国现行标准(GB177-1999)规定,以 1∶3 的水泥和 ISO 标准砂,按规定的水灰比 0.50, 用标准制作方法制成 4cm×4cm×16cm 的标准试件。在标准养护条件下,达到规定龄期(3d、 28d)时,测定其抗折和抗压强度,按国家标准规定的最低强度值来评定其所属的强度等级。 ? 为提高水泥的早期强度,我国现行标准将水泥分为普通型和早强型( R) 。早强型水泥 的 3d 抗压强度较同强度等级的普通型强度提高 10-24%,可达 28d 抗压强度的 50%。道路水泥 多用早强水泥。

? ?

需要强调的是,我国现行国家标准规定,凡是氧化镁、三氧化硫、初凝时间、安定性中的 任何一项指标不符合标准规定的,均为废品。 凡细度、终凝时间、不溶物和烧失量中的任何一项不符合标准规定的,或混合材掺加 量超过最大限量,或强度低于等级规定的指标时称为不合格产品。废品水泥在工程中严禁使用。 第二章 硅酸盐水泥熟料的组成 第三节 硅酸盐水泥熟料的化学成分 ? 水泥的质量主要决定熟料的质量。优质的熟料应该具有合适的矿物组成和岩相结构。 因此控制熟料的化学成分,是水泥生产的中心环节之一。一、熟料的化学组成 ? 硅酸盐水泥熟料的主要化学组成为氧化钙( CaO ) ,一般范围为 62-67% ;二氧化硅 (SiO2) ,一般范围为 20-24%;三氧化二铝(Al2O3)一般范围为 4-7%;三氧化二铁(Fe2O3) , 一般范围为 2.5-6%。这四种氧化物组成通常在熟料中占 95%以上,同时含有 5%以下的少数氧 化物,如氧化镁(MgO) 、硫酐(SO3) 、氧化钛(TiO2) 、氧化磷(P2O5)以及碱(k20、Na20) 等。

这四种氧化物构成水泥熟料的最主要的化学成分。它们在水泥熟料生产中是按一定含量和 一定比例进行配比生产的。配比不恰当,都会直接影响到熟料的质量进而影响到水泥的质量。 如熟料中若 CaO 含量过高,则 CaO 不能充分与硅酸性氧化物化合,部分呈现游离状态存在于 熟料中,成“死烧状态”。这种“死烧状态”的氧化钙,其水化作用非常缓慢,常发生在水泥凝结 硬化过程之后的水泥石中,致使水泥石膨胀变形、破裂。如氧化铝和氧化铁,它们是熟料烧成 过程中产生液相的主要氧化物,如果它们的含量过高,则产生的液相量过多,使物料易结大块 而影响操作;如果含量过低,则产生液相量过少,使烧成困难,熟料易于“粉化”。所以在熟料 生产中化验人员要对原料进行认真分析计算,作出科学合理的配料方案,指导熟料生产。 第四节 熟料的矿物组成 ? 一、熟料中的主要矿物 ? 原料中 CaO、SiO2、Al2O3 和 Fe2O3,这四种氧化物, 经过高温煅烧后发生化合反应: ? 硅酸盐矿物(CaO、SiO2)生成:硅酸二钙(2CaO· SiO2) ,简写为 C2S 和硅酸三钙 (3CaO· SiO2) ,可简写为 C3S,合计占 75%左右。 ? 熔剂矿物(Al2O3 和 Fe2O3)生成:铝酸三钙(3CaO· Al2O3),可简写为 C3A、铁铝酸 四钙(4CaO· Al2O3·Fe2O3)简写为 C4AF,合计占 22%左右。

? ?

另外还有少量的游离氧化钙(F-CaO) 、方镁石、含碱矿物(R02)以及玻璃体等。

从以上熟料的矿物组成中可以看出,在水泥熟料中,CaO、SiO2、Al2O3、Fe2O3 这四种氧 化物,不是以单独的氧物形式存在,而是经过高温煅烧后,两种或两种以上的氧化物反应生成 的多种矿物集合体,其结晶细小,通常为 30-60Um。因此水泥熟料是一种多矿物组成的结晶 细小的人造岩石。 第五节 熟料的率值

? ? ? ? ? ?
? ? ?

硅酸盐水泥熟料中各氧化物不是以单独状态存在,而是由两种或两种以上的氧化物合成的 多矿物集合体。因此,在水泥生产中不仅要控制各氧化物的含量,还要控制多氧化物之间的比 例,即率值。这样更能表示出水泥的性质及对煅烧的影响。 率值就是用来表示水泥熟料中多氧化物之间相对含量的系数。它是生产控制的一种指标。 一、水硬率

表示水泥熟料中氧化钙与酸性氧化物(SiO2、Al2O3、 Fe2O3)之和的质量百分数的比值, 用 HM 或 m 表示。 计算公式如下:HM(m)=CaO/ SiO2+ Al2O3+ Fe2O3 通常波动值在 1.8-2.4 之间。

二、硅率(硅硅率)和铝率(或称铁率) 1、硅率 表示熟料中氧化硅含量与氧化铝、氧化铁之和的质量比。也表示熟料中硅酸盐矿物与溶剂 矿物的比例。用 SM 或 n 表示:计算公式如下: ? SM(n)= SiO2/ Al2O3+ Fe2O3 ? 通常硅酸盐水泥熟料的硅率在 1.7-2.7 之间。 ? 2、铝率 ? 铝率又称铁率或铝氧率。表示熟料中氧化铝和氧化铁含量的质量比,液表示熟料溶剂矿物 中铝酸三钙与铁铝四钙的比例,用 IM 或者 p 表示。计算公式如下: ? IM(p)= Al2O3/ Fe2O3 ? 通常硅酸盐水泥熟料的铝率在 0.9-1.7 之间。

三、石灰饱和系数 KH 值

为熟料中全部氧化硅生成硅酸钙(C2S 和 C3S)所需的氧化钙含量与全部氧化硅生成硅酸 三钙所需氧化钙含量的比值,也即表示熟料中氧化硅被氧化钙饱和形成硅酸三钙的程度。计算 公式为:
?

?

KH= (CaO –1.65Al2O3-0.35Fe2O3)/2.8SiO2

为使熟料顺利形成,不出现过量游离石灰,通常 KH 值控制在 0.82-0.96 之间。 第三章 硅酸盐水泥的生产方法及工艺 ? 第六节 生产方法分类 ? 由于各地条件、原料资源和采用的主机设备情况的不同,水泥生产方法也有所不同。大致 有以下几类: ? 一、按生料的制备方法分为湿法和干法 ? 1、湿法:将原料加水粉磨成生料浆(含水 33-40%)后喂入湿法回转窑煅烧成熟料, 则称为湿法;将湿法制备的生料浆脱水后,制成生料块入窑煅烧,称为半湿法,亦归入湿法。 ? 2、干法:将原料同时烘干与粉磨或先烘干后粉磨成生料粉,而后喂入干法窑内煅烧成 熟料,则称为干法生产;将生料粉加入适量水分制成生料球,而后喂入立窑或立波尔窑内煅烧 成熟料的方法叫半干法,亦归入干法。

? ? ? ? ? ? ? ? ?
? ? ? ? ? ? ?

二、按煅烧熟料窑的结构分类 1、立窑:有普通立窑和机械化立窑。 2、回转窑: 中空式窑 湿法回转窑 回转窑 干法回转窑 半干法回转窑 带热交换装置的窑 带余热锅炉的窑 带预热器的窑 带分解炉的窑 立波尔窑

三、各种生产方法的特点 (一)立窑生产的特点 1、优点 (1)基本建设投资小,投入生产快。 (2)立窑内填充系数高,因而单位体积产量高。 (3)可以就地取材,充分利用地方资源。 (4)窑内传热效率高,散热损失小,约为总热值的 3%(回转窑为 15%) ,可节约烧 成用燃料。 ? (5)需要设备和动力容量少,故可节约钢材和动力。 立窑生产的特点

? ? ? ? ?

2、缺点: (1)生产规模小。 (2)熟料质量较差。 (3)劳动生产率低,劳动强度大,单机产量低。

(4)环保达标难。 (二)回转窑的特点

湿法回转窑生产热耗高,但电耗较低,生料易于均化,成分均匀,熟料质量较高且输 送方便,粉尘少。所以此生产方法在 20 世纪 30 年代左右得以迅速发展。缺点是能耗高。 ? 新型干法回转窑是当前世界各国竞相发展的窑型。悬浮预势器窑和窑外分解窑技术的 开发成功,使水泥生产方法开始逐步发生变化,出现了向干法发展及湿法改干法的发展趋势。 新型干法回转窑的优点是节能、产量高、质量稳定、环保、生产率高。 四、硅酸盐水泥的生产工艺过程

?

附:1、干法回转窑生产工艺流程图

第四章 硅酸盐水泥熟料的主要原料 ? 水泥的质量主要取决于熟料的质量。煅烧优质熟料必须制备适当成分的水泥生料。而生 料的化学成分是由原料提供的。只有当原料提供的成分符合要求,加上良好的煅烧与粉磨,才 能生产出优质水泥。因此,水泥原料的开采和合理使用,是水泥生产首先需要解决的问题。 ? 自然界中很难找到一种单一原料,能完全满足水泥生产的要求。因此需要采取几种不 同的原料,根据所生产水泥的种类和性能,进行合理搭配,即通过配料,组成配合原料,再把 它粉磨成一定细度,才能制得适当成分的生料。因此,生料配料是为了确定各原料各组分的数 量比例,以保证得到成分和质量合乎要求的水泥熟料。 第七节 原料的种类

?

生产硅酸盐水泥用的原料,主要是石类质原料(主要提供氧化钙)和粘土质原料(主要提 供氧化硅、 氧化铝和少量氧化铁) 。 我国粘土质原料及燃料灰分一般氧化铝较高, 含氧化铁不足。 因此,当用这两种原料配合后,其成分满足不了水泥熟料成分要求时,需用铁质校正原料,即 采用石灰质原料,粘土质原料和铁质校正原料进行配料。

? ?

一、石灰质原料 凡是以炭配钙为主要成分的原料都属于石灰质原料。 常用的天然石灰质原料有石灰岩、 泥灰岩、白垩、贝壳等。我国水泥生产中应用最普遍的是石灰岩。我州石灰岩储量丰富,在省 内名列第二,水泥产业具有得天独厚的发展条件。 ? 石灰岩。石灰岩是一种沉积岩。主要矿物是方解石、粘土和石英或燧石等杂质。纯净 的石灰石是白色的,由于含不同的杂质而呈灰白、青灰、淡黄、红褐等颜色。常见的为青灰色, 密度 2.6-2.8,硬度 8-10,一般呈块状,有白色条痕。

? ?

纯的方解石含有 56%CaO 和 44%CO2。生产硅酸盐水泥用石灰岩中氧化钙含量,应大于等 于 48%。对于氧化钙低于 48%的石灰岩可与氧化钙含量大于 48%的石灰岩搭配使用,搭配后的 石灰岩其 CaO 含量必须在 48%以上。 石灰石的质量要求如下表:

? ?

二、粘土质原料 我国天然粘土质原料的种类较多,有黄土、粘土、页岩、泥岩、粉砂岩及河泥等,其 中应用最广泛的是黄土和粘土。 ? 粘土是由花岗岩、玄武岩等经风化分解后,再经搬运或残积形成。黄土主要分布在华 北和西北地区。粘土类包括华北、西北地区的红土、东北地区的粘土、南方地区的红壤、黄壤 等。衡量粘土质量主要看粘土的化学成分(硅率、铝率) 、含砂量、碱含量及粘土的可塑性、热 稳定性、正常流动的需水量等工艺性能,如要求硅率 2.5-3.5%(最好 2.7-3.1) ;铝率 1.5-3%等。 ? 粘土质原料的质量要求如下:

三、校正材料

当石灰质原料和粘土质原料配合所得生料成分不能符合配料方案要求时,必须根据所缺少 的组分,掺加相应的校正原料,以补充某些成分的不足,常用较正原料有低品位铁矿石、铁厂 尾矿、硫铁矿渣;硅藻土、硅藻石、砂岩、粉砂岩、铝矾土、铝渣等。 校正原料的质量要求如下:

第八节 原料的开采和运输 水泥厂一般要求都有自己的原料矿山。水泥厂的原料均属非金属矿床。非金属矿床的 开采按开采对象和开采方法,可分为露天开采和地下开采。露天开采又可分为机械开采和水力 开采。目前使用最多的是机械开采。机械开采是用一定的采掘运输设备,按一定的生产工艺, 从地面将矿体四周的岩体及覆盖层剥离掉,把矿石采出来并通过露天沟道或运输设备运到厂区 料场的开采方法。 ? 矿石运输: 根据采石场距工厂的距离长短来选择运输设备。 一般采石场距工厂 300-500 m时,则可采用皮带输送机、相距在 3Km 以内时,采用自动卸料汽车或小型内燃机车运输。 ? 矿山管理要贯彻“采剥并举,剥离先行”的原则,矿山要实行计划开采,不同质量的矿 石要分别开采和存放,搭配使用。稳定进厂原料成分,达到配料要求。 第九节 原料的预均化
?

?

经破碎的原料的化学成分是很不均齐的。为使原料成分初步趋于均齐,充分发挥原料 堆场在储存和取用原料两方面的功能,采用一定的堆放和取用方式,使生料得到均齐,叫原料 的预均化。原料预均化的基本原理是“平铺直取”。即采取堆料机将料一层一层地铺起来,用料 时,采用取料机垂直切取料层,这样取得的生料就较均齐,接着送入生料磨进行粉磨。 第十节 生料的制备、调整和均化

? ?

一、生料制备

生料制备是将原料(石灰质原料、粘土质原料及少量较正原料,立窑煅烧水泥熟料时 还加有一定量的燃料)经过一系列的加工过程后,制成具有一定细度、适当化学成分,并且均 匀的生料,使其满足多种窑型的煅烧要求。

? ?

(一)对生料的要求 (1)生料成分的均匀性。生料成分均匀稳定对熟料烧成具有重要影响。衡量生料成分 稳定性的重要指标是碳酸钙滴定值,出磨生料碳酸钙滴定值波动范围,湿法窑不大于±0.15%; 干法窑不大于±0.4%;立窑不大于±0.5%。 ? (2)细度:一般生料以 0.08mm 方孔筛筛余量应控制在 8-10%,0.2mm 方孔筛筛余不 大于 10%为宜。 ? (3)生料的水分:湿法,料浆含水份 33-40%;干法一般控制在 1.2%以内。

? ?

(二)生料制备的过程。 1、破碎:是用机械方法缩小物料粒度的过程。破碎物料主要有压碎、击碎、磨碎、劈 碎四种方式。采用的破碎设备有颚式破碎机、锥式破碎机、辊式破碎机、锤式破碎机、反击式 破碎机等。 (动画图) ? 破碎作业有一级、二级甚至三级破碎的程序。采用几级破碎,主要取决于破碎机的技

术性能。一般级数越少越好。但不论选用几级或选用什么样的破碎机,石灰石破碎系统的出料 粒度必须满足生料磨入磨要求,在我国一般为 20-25mm。 ? 2、烘干 ? 在干法粉磨时,入磨物料平均水分应控制在 1-2%以内,但天然物料水分一般都远远超 过这一范围,因此物料必须烘干,满足这一要求。

? ? ? ? ? ? ? ? ?

水泥厂采用的烘干方法有两种:一种是粉磨过程中同时进行烘干,即利用烘干兼粉磨的设 备;另一种是采用单独的烘干设备,物料烘干后再进行入磨。主要的烘干设备有:回转式烘干 机、悬浮式烘干机和硫态化烘干机。 (动画图)

3、粉磨

破碎与烘干后的物料,通过配料过程和配料设备送至生料磨进行粉磨。粉磨系统主要 有开路和闭路两种。在粉磨过程中,当物料一次通过磨机后即为产品时,称为开路系统,当物 料出磨后经过分级设备 (选粉机) 选出产品, 而使粗料返回磨内再磨时称为闭路系统。 (动画图)

生料的细度:一般控制在 0.08mm 方孔筛筛余 10%左右,0.2mm 方孔筛筛余小于 1.5%以内 为宜。 三、生料均化 出磨的生料粉或生料浆,其化学成分难免有些波动,为保证入窑生料化学成分均齐、 合格,生料应在贮存均化库内进行均化。 (CF 均化库动画图) 干法生料的均化可采用多库搭配,机械倒库和压缩空气搅拌库。

第五章 硅酸盐水泥熟料的制备 ? 第十一节 硅酸盐水泥熟料的煅烧 ? 熟料煅烧是硅酸盐水泥生产工艺过程的第二阶段。是指将生料制备过程中制得的生料 送入煅烧窑,经高温煅烧,发生一系列物理的、化学的和物理化学变化后形成熟料的工艺过程。 虽然生产方法和各种煅烧窑各有不同,但熟料煅烧过程大体相同。下面以湿法回转窑为例,来 说明熟料的煅烧过程: ? 熟料煅烧物料可分为:水分蒸发→生料预热→生料分解→熟料煅烧→熟料冷却五个功 能单元。相应分为干燥带、预势带、分解带和放热带,烧成带和冷却带。

? ?

一、干燥带(物料温度 150℃) 承担生料中水分的蒸发任务。湿法窑物料含 32-40%的水分,经干燥后,物料水分减到 22-26%,浆料失水变成球状。 ? 干法窑由于入窑生料水分小于 1%, 几乎没有干燥带。 半干法窑的干燥过程在加热机上 进行,在回转窑内无干燥带。预热器窑、窑外分解窑干燥在预热器内进行,因此回转窑内无干 燥带。H20↑。 ? 二、预热带(物料温度 150-750℃) ? 承担粘土质等原料中化学水的分解脱水任务。 当温度升到 400-550℃时, 粘土开始脱水 分解出活性 SiO2 和 Al2O3,当温度升到 600-700℃时,MgCO3 继续分解。带悬浮预热器和加热 机的窑,预热都在窑外进行,回转窑内预热带很短或者没有。

五、烧成带(物料温度 1300-1450℃-1300℃) 该带又称烧结带,是回转窑内温度最高的一带,物料进入这带就出现液相,在液相中 C2S 和游离氧化钙作用形成 C3S 即:Ca0+C2S→C3S,因此,此带也叫“石灰吸收带”。为 C3S 的生 成反应完全,物料在此停留的时间,也就是烧成带应有一定长度,因此,要求回转窑内燃料燃 烧的火焰应有一定的长度和温度。 ? 六、冷却带(物料温度 1300—1000℃) ? 在烧成带形成的 C3S、C2S、C3A、C4AF 四种主要矿物的晶体继续向前运动与温度较低的 二次空气相遇,熟料温度下降,这一区域称为冷却带。在该带快速冷却后,形成含 C3S、C2S、 C3A、C4AF 圆形颗粒和玻璃体--阿利特晶体,落入冷却机内。 ? 立窑内煅烧大体与回转窑相同,此不再叙述。 2、看回转窑动画图

第十二节

水泥制成工艺

水泥制成工艺是水泥生产的最后一环。是指把熟料、石膏、混和材共同粉磨制成水泥,再 进行包装或散装出厂。工艺过程如下: 熟料 石膏 ↘ →(冷却) ↗包装机→成品库→出厂 ↘散装车→出厂 →水泥磨机→水泥库均化

混合材↗

第十三节 水泥的包装和贮运 ? 一、水泥的包装 ? 水泥是一种粉状物,在运输和储存方面须有不同形式的容器,我国一般出厂水泥有袋装和 散装两种,国外还有桶装和集装袋等。袋装水泥一般采用纸装或塑料编织袋包装,散装一般有 火车散装及船运散装等。 ? 包装的设备有固定式和回转式两种。 固定式包装机有单咀、 2 咀、 4 咀三种规格。 生产率低, 劳动条件差。 ? 回转式包装机有 6 咀、10 咀、14 咀三种规格。自动化程度高、包装能力大、劳动条件好。 (有动画图) ? 一、水泥的贮存
