Abstract

本发明涉及用于水泥工业窑的含石墨的未烧耐火砖以及所述耐火砖在前述窑中的应用，以抵抗相关的窑内热及物理化学变形。本发明的砖组合物含有75重量%到62重量%的碳酸镁(MgCO3)，12重量%到20重量%的矾土(Al2O3)以及4重量%到11重量%的石墨。所述组合物还含有9重量%到7重量%用以改善耐热冲击性、耐热性和耐氧化性的添加剂(由铝粉、硅金属、碳化硅和粘土组成)以及3重量%到4重量%的树脂。所述耐火材料可用来涂覆水泥窑中高低两处的过渡区域(4)及烧结区域(5)的内部。

Description

用于水泥窑的含石墨未烧耐火砖及其应用
本专利保护的发明是用于水泥窑的含石墨未烧耐火砖及其应用。
因而本发明是用来为水泥窑加衬的砖。该砖由镁和铝构成，并含有石墨用以替代其他方案中的铬或铁，该砖可局部配置于能最大限度地利用其耐火能力的窑特定区域。
在水泥工业中，使用耐火材料为窑内侧加衬以抵抗较高工作温度是众所周知的，所述工作温度在窑的某些部分可高达1,500℃，并且在800-1500℃范围内快速变化，伴有引起的物理和化学反应。然而，不同组成的耐火材料具有不同程度的硬度和抗变形能力。本发明获得了比迄今为止所采用材料具有更高硬度和抗变形性，因而具有更长寿命的耐火材料。
当前已知并使用有各种耐火材料，但它们都存在操作和功能上的缺点，特别是在由较高和快速改变的窑温而引起的渐进变形以及随之而致的化学反应方面。由此，相比较于此处描述的本发明的技术和成本优点，迄今开发的材料的使用存在某些局限性。由此，玻璃制造中的坩埚，石灰石，硅、铬、铝的氧化物和硅-明矾玻璃的应用(F.H.Norton，Refractarios，1972年由Blume出版的西班牙语第一版)或者关于耐火砖的孔隙率的作用的日本专利号JP11230679，作为耐火面板的日本专利号JP11130485，或者作为玻璃结构的日本专利号JP11201649，关于形状的配置，其中领先的申请之一是关于预制砖的欧洲专利号EP0911594和德国专利号DE19729582，或者PCT号为WO02/059057的本申请人的发明专利，所有这些均与此处提供的本发明接近但是较普通且不精确。这些专利均为源自化学组成或配置的发明，要么并不特别适用于水泥工业，要么是置于水泥窑中的不同区域。
这些缺陷被具有如下化学组成的本发明所克服：碳酸镁(MgCO3)，矾土(Al2O3)，石墨，改善操作功能性和性能并且其结构提供了低孔隙率和高耐火能力的改进添加剂和粘合树脂。
这些耐火砖可按如下方式配置：
关于化学组分，重量百分比为75％到62％的碳酸镁(MgCO3)；海水镁；重量百分比为12％到20％的矾土(Al2O3)，以及4％到11％的石墨。对于纯度，石墨的等级应为94％结晶性。同样地，用以改善耐热冲击性、耐热性和耐氧化性的添加剂(铝粉、硅金属、碳化硅和粘土的组合)的重量百分比应在9％到7％。还应采用相对于总百分比的重量百分比为3％到4％的粘合剂。
总之，该元素组合所得结果导致具有更高硬度并且对热和物理及化学反应具有更高耐受性的产品技术优势，由此可得到各种显著的经济利益，采用该新发明，窑的停工数减少了，每一工作阶段用于材料的维修和更换的耗费量减少了，并且对于最繁忙的窑一回转窑，在生产过程中的优势是获得更高耐受性和硬度。
为对前述一般特性及对于本申请有更好了解，此处附有数张如下所述的本发明附图。
图1：采用附属冷却器的成一单元的水泥工业回转窑侧视图，所述单元由热交换器(1)，煅烧区域(2)，安全区域(3)，高低两处的过渡区域(4)，烧结区域(5)，出口区域(6)，冷却器(7)，窑头(8)和火焰喷射器(9)组成。
图2：带有栅格冷却器配置于一个单元内的回转水泥窑侧视图，所述单元包括热交换器(1)，燃烧器区域(2)，安全区域(3)，高低两处的过渡区域(4)，烧结区域(5)，出口区域(6)，冷却器(7)，窑头(8)和火焰喷射器(9)。
并且示出了水泥窑中采用了耐火砖的区域：高低两处的过渡区域(4)和烧结区域(5)的配置。
