为了研究开发新的球团粘结剂,取代或减少现有球团膨润土用量,炼铁和造块工作者巳做了大量的试验研究工作。并开发出KLP系列有机添加剂在球团、炼结中获得试用成功,但因其价格昂贵(万元左右/t)。故至今仍未在工业生产大量推广使用。 1995年。杭钢与临安第三膨润土化工总厂和武汉科技大学合作研究开发出球团矿新型复合粘结剂(简称复合土)。择优研制出F—D′、F—B′新型复合粘结剂。在此基础上。1996年又作了扩大规模的复合土批量试产和杭钢竖炉投笼试验以及工业性竖炉生产和高炉冶炼试验。在实验室条件下,球团粘结剂配比可降至1.0%,而在目前杭钢8m~2竖炉生产条件下。从膨润土配比2.2%降至复合土配比1.5%,生产实践表明:其成球速度加快,造球强度、爆裂温度提高,成品球坑压强度、转鼓
In order to study the development of new pellet binders, replacing or reducing the amount of pellets used, iron and steelmaking workers have done a great deal of experimental work. And developed KLP series of organic additives in pellets, refining trial was successful, but because of its expensive (million or so / t). Therefore, it is still not widely promoted in industrial production. the year 1995. Hangzhou Iron and Steel Co., Ltd. and Lin’an third bentonite Chemical Plant and Wuhan University of Science and Technology cooperation in research and development of pellets new composite binder (referred to as composite soil). Preferentially developed F-D ’, F-B’ new composite binder. on the basis of. 1996 also made an expanded scale of the trial production of composite soil and Hang cage furnace cage test and industrial shaft furnace production and blast furnace test. In the laboratory conditions, the pellet binder ratio can be reduced to 1.0%, while in the current Hang Hau 8m ~ 2 shaft furnace production conditions. From 2.2% of bentonite to composite soil ratio of 1.5%, the production practice shows that: the ball into the speed, pelletizing strength, burst temperature, the finished ball pit pressure intensity, drum
