Description

一种低成本中包干式料的制备方法
技术领域
本发明涉及耐火材料，特别涉及一种低成本中包干式料的制备方法。
背景技术
我国每年产生的400多万吨用后耐火材料若能作为二次资源得到充分的利用，不但为我国节约大量的资源，提高社会效益将超过60亿元/年。特别对改善和保护环境起到重要的作用。因此，对用后耐火材料再利用不但对提高企业效益、社会效益和改善环境有重要意义。这些用后耐火材料若经过拣选、分类和特殊的工艺处理，不但可以生产优质的不定形耐火材料，而且还能再生出优质的定形产品以及其他材料。用后耐火材料得到充分再利用不仅可节约国家的矿产资源和能源，而且也可减少环境污染，大大降低耐火材料的成本和炼钢成本。
目前广泛使用的中间包镁质干式工作衬具有施工简便，热效率高，渣壳清除率高，周转快，使用寿命长等优点，取得了优良的使用效果。但是随着镁砂原料价格的攀升，人们欲寻求一种价格低廉可以替代或部分替代镁砂而不影响中间包使用性能的原料。因此，在中间包干式料用废镁碳砖替换镁砂具有一定的现实意义。
本项目主要是在中间包干式料的基础上废镁碳砖部分替换镁砂，在保证干式料使用性能的前提下，降低材料的原材料成本，节约资源，保护环境，提高企业的市场竞争力。
发明内容

一种低成本中包干式料的制备方法，具体步骤如下：
1)原料选择、粉碎、筛分和细磨
将镁砂在破碎机中破碎，分别制成0-1mm、1-3mm和200目的三种粒径的原料；
将橄榄石在破碎机中破碎，分别制成0-1mm和1-3mm的两种粒径的原料；
将废镁碳砖在破碎机中破碎，制成200目的粒径的原料；
2)配比
按配方称取原料；
3)混练
原料固体和结合剂搅拌混合均匀，保证净混时间不低于12min，然后出料。
4)出料
