Environment-friendly water-based large fabric for converter fettling
The invention relates to an environment-friendly water-based large fabric for converter fettling. The fabric comprises the following components in parts by weight: 80-90 parts of magnesia, 6-10 partsof binding agent, 0.5-1 part of slaked lime and 0.5-1 part of bentonite. The preparation method comprises the steps: adding water into the supplementary material, stirring to form porridge, pouring the stirred material into a position needing to be repaired in the converter, burning for 15-25 minutes at 800-1350 DEG C, and finishing the repair when the supplementary material is large and the surface material turns red. Compared with a common converter large-area fettling material, the sintering time is shortened by about 30 minutes; during sintering, no smoke, no odor and no harmful volatile matter exist, and no harm is caused to human bodies and the environment; and during sintering, gunning operation can be carried out so that the steelmaking efficiency is improved.
本发明涉及一种环保型转炉补炉用水基大面料，其包括镁砂、结合剂、消石灰、膨润土，所述镁砂80~90份，结合剂6~10份，消石灰0.5~1份，膨润土0.5~1份。补料中加水搅拌至成粥状，将搅拌好的料倒入转炉中需要修补的位置，在800~1350℃下，烧15~25分钟，补料大面料泛红色，修补完毕。本发明比普通转炉大面补炉料烧结时间缩短30分钟左右；烧结时，无烟、无味、无有害挥发物，对人体及环境无害；在烧结的同时，可以进行喷补作业，以提高炼钢效率。
