Description

一种钢渣与渣盆分离剂
技术领域
本发明涉及炼钢技术领域，特别是一种钢渣与渣盆分离剂。
背景技术
炼钢中产生的钢渣一般先放置于渣盆内，再通过渣盆倾倒至渣场，倾倒后取回渣盆重复使用。如果渣盆的内壁上不涂覆任何分离剂，倾倒钢渣时钢渣易粘附在渣盆上，与渣盆不易分离，传统技术多通过敲打渣盆实现钢渣与渣盆的分离，敲打渣盆既会损坏渣盆，又容易引起钢渣飞溅，造成安全事故。现有技术采用耐火骨料、抗渣剂、粘结剂、悬浮剂及其他添加剂配制成钢渣分离剂并涂抹于渣盆内壁形成具有一定厚度、与渣盆结合良好、易与钢渣分离的光滑涂层，该光滑涂层具备1750℃以上的耐火、耐高温、抗侵蚀性，倾倒渣盆时钢渣依靠自身重力与该光滑涂层自然分离。但是，该分离剂价格高，采购成本为2000元/吨。如何设计一种价格低廉、与渣盆结合性能良好、易与钢渣分离的钢渣与渣盆分离剂，是目前需要解决的技术问题。
发明内容
为解决上述技术问题，本发明提出一种价格低廉、与渣盆结合性能良好、易与钢渣分离的钢渣与渣盆分离剂。
本发明的技术方案是这样实现的：
一种钢渣与渣盆分离剂，包括主料与辅料，每1kg主料中包括如下重量的组分：耐火粘土0.5-0.8kg、尾矿砂0.12-0.475kg、增碳剂0.01-0.04kg及膨润土0.005-0.02kg，辅料包括水玻璃、CMC和水，每1kg主料配合如下辅料使用：水玻璃5-10ml、0.5％CMC 2-8ml及水1-3kg。
优选的，每1kg主料中包括如下重量的组分：耐火粘土0.65kg、尾矿砂0.32kg、增碳剂0.02kg及膨润土0.01kg，辅料包括水玻璃、CMC和水，每1kg主料配合如下辅料使用：水玻璃7.5ml、0.5％CMC 5ml及水1.5kg。
更为优选的，主料的粒度分布为：小于0.074mm的占60-70％，0.074-0.2mm的占15-20％，0.2-0.5mm的占5-10％，大于0.5mm的占5-10％。
作为优选的，主料的粒度分布为：小于0.074mm的占68％，0.074-0.2mm的占16.8％，0.2-0.5mm的占7.2％，大于0.5mm的占8％。
与现有技术相比，本发明价格低廉、与渣盆结合性能良好、易与钢渣分离，而且使用简单，只需按比例配合，搅拌均匀后以现有的涂抹方式涂覆于渣盆内壁即可。
具体实施方式
下面将结合实施例对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
