Abstract

本发明涉及炼钢用硼复合熔剂，熔剂是由下述成分按重量份比例制成：200目的生矾土粉：10-40份；200目的硼尾矿：60-90份；本发明与现有技术相比的有益效果是：该发明产品代替萤石和铝酸钙对解决现有熔剂萤石污染、铝酸钙成本高，对解决硼尾矿和硼泥占地污染环境，搞好矿产资源综合利用，推动循环经济高速健康发展，降低炼钢成本，都具有重要意义。

Description

炼钢用硼复合熔剂
技术领域
本发明涉及钢铁冶金炼钢用硼复合熔剂。
背景技术
长期以来，我国在炼钢过程中普遍使用萤石或合成铝酸钙等进行造渣和化渣。萤石虽然对造渣和化渣有利，但它在高温下容易分解，使水和空气中F-含量超标，造成空气和循环水的严重污染；铝酸钙等不存在污染问题，但生产成本较高，影响推广应用。
辽宁省有丰富的废弃硼尾矿或硼泥资源，利用废弃硼尾矿或硼泥为原料，制作炼钢用硼复合熔剂，是本申请人研究的重要项目。
发明内容
本发明的目的是提供一种炼钢用硼复合熔剂，是利用废弃硼尾矿或硼泥为主要原料，加入不同比例的矾土，确定出熔点不高于1400℃的熔剂配方。
炼钢用硼复合熔剂，其特征在于该熔剂是由下述成分按重量份比例制成：
1)200目的生矾土粉：10-40份；
200目的硼尾矿：60-90份；
工艺流程为：
所述的原料按要求的重量份比例配料，压球，干燥，烧结，出成品。
成品技术性能指标为：
熔剂1)
化学成分/％
B2O3         5～8
Al203        10～35
粒度组成/mm  5～30
熔化温度/℃  约1300
以上熔剂：
第一，本身熔点低，在炼钢条件下受热即化；
第二，与渣反应性好，生成物熔点也低，易流动和铺展。
本发明与现有技术相比的有益效果是：
该发明产品代替萤石和铝酸钙对解决现有熔剂萤石污染、铝酸钙成本高，对解决硼尾矿和硼泥占地污染环境，搞好矿产资源综合利用，推动循环经济高速健康发展，降低炼钢成本，都具有重要意义。
具体实施方式
实施例1
炼钢用硼复合熔剂，该熔剂是由下述成分按重量份比例制成：
200目的生矾土粉：30份；
200目的硼尾矿：  70份；
工艺流程为：
所述的原料按要求的重量份比例配料，压球，干燥，烧结，出成品。
实施例2
炼钢用硼复合熔剂，该熔剂是由下述成分按重量份比例制成：
200目的生矾土粉：10份；
200目的硼尾矿：90份；
工艺流程为：
