一、新型干法水泥生产工艺流程 1、破碎及预均化
破碎水泥生产过程中,大部分原料要进行破碎,如石灰石、黏土、铁矿石及煤等。石灰石是生产水泥用量最大的原料,开采后的粒度较大,硬度较高。原料预均化预均化技术就是在原料的存、取过程中,运用科学的堆取料技术,实现原料的初步均化,使原料堆场同时具备贮存与均化的功能。 2、生料制备
水泥生产过程中,每生产1吨硅酸盐水泥设备至少要粉磨3吨物料(包括各种原料、燃料、熟料、混合料、石膏),据统计,干法水泥生产线粉磨作业需要消耗的动力约占全厂动力的60%以上,其中生料粉磨占30%以上,煤磨占约3%,水泥粉磨约占40%。因此,合理选择粉磨设备和工艺流程,优化工艺参数,正确操作,控制作业制度,对保证产品质量、降低能耗具有重大意义。 3、生料均化
新型干法水泥生产过程中,稳定入窑生料成分是稳定熟料烧成热工制度的前提,生料均化系统起着稳定入窖生料成分的最后一道把关作用。 4、预热分解
水泥机械把生料的预热和部分分解由预热器来完成,代替回转窑部分功能,达到缩短回窑长度,同时使窑内以堆积状态进行气料换热过程,移到预热器内在悬浮状态下进行,使生料能够同窑内排出的炽热

The Nature of the Construction Industry
The construction industry is a paradox in many ways. In its roughly 8.3 percent, $418 billion-plus share of the United States’ gross national product(1988), it is the largest industry, but the vast majority of its hundreds of thousands of participants are small business. There are over half a million construction firms in the United States alone. These firms are intensively competitive among themselves in the best traditions of the free enterpr

陶瓷的烧结过程:可分为初期、中期、后期三个阶段。烧结初期只能使成形体中颗粒重排,空隙变形和缩小,但总表面积没有减小,并不能最终填满空袭;烧结中、后期则可能排出气体,使孔隙消失,得到充分致密的烧结体。烧结方法还有热等静压、水热烧结、热挤压烧结、爆炸烧结、等离子体烧结、自蔓延高温烧结等。
自蔓延高温烧结是利用金属与硅、硼、碳、氮等互相作用的强烈放热效应,不利用外部加热源,而利用元素内部潜在的化学能将原始粉末在几秒到几十秒的极短时间内转化成化合物或致密烧结体。优点:不需要高温炉,过程简单,几乎不消耗电能,制得的产品纯净,能获得复杂相和亚稳相等。主要缺点:不易获得高密度材料,不易严格控制制品性能,所用原料往往易燃及有毒,存在一定的安全隐患。
陶瓷三相:晶相、玻璃相和气相。晶相—是陶瓷的主要组成成分,一般数量较大,对性能的影响也较大。它的结构、数量、形态和分布,决定了陶瓷的主要特点和应用。又分为主晶相和次晶相;当陶瓷中有数种晶体时,数量最多、作用最大的为主晶相。玻璃相—陶瓷中玻璃相的作用是:①将晶相颗粒粘结起来,填充晶相之间的空隙,提高材料的致密度;②降低烧结温度,加速烧结过程;③阻止晶体转变,抑制晶体长大;④获得一定程度的玻璃特性,如透光性及光泽等。玻璃
