转底炉处理钢铁厂含锌粉尘压团粘结剂研究
|
Abstract:
本文结合宝武集团上海转底炉的含锌粉尘原料情况和压团生产工艺，针对不同种类粘结剂原料开展研究工作，开发出一种新型复合粘结剂，并与常规使用的淀粉粘结剂、膨润土粘结剂进行对比。结果表明：当新型粘结剂用量为3.3%~4%、压团混合料水含量为14%、压球机成型压力为10 MPa时，球团质量指标较好，可满足转底炉生产需求，同时，与单一淀粉粘结剂和膨润土粘结剂相比，使用复合粘结剂制成的球团具有指标好、成本低的优势。
Combined with the raw materials of zinc-containing dust and the briquette production process of the Shanghai rotary hearth furnace of Baowu Group, we carried out research work on different types of binders, and developed a new type of composite binder, and compared with the conventional use of starch binder and bentonite binder. The results show that when the dosage of the new binder is 3.3%~4%, the water content of the briquette mixture is 14%, and the molding pressure of the briquette machine is 10 MPa, the pellet quality index is good, which can meet the production requirements of the rotary hearth furnace. Meanwhile, compared with starch binder and bentonite binder, the pellets made of composite binder have the advantages of good index and low cost.
