上钢八厂在科研、设计和施工单位的密切配合下,将一座炉底水管汽化冷却加热炉,改造成无水冷滑轨加热炉,并辅以热工自动控制。经过一年多的生产实践,在该厂工人师傅认真摸索操作经验和不断改进下,已取得了高产、优质、低消耗的良好效果,为把钢铁生产搞上去作出了新的贡献。改造前的加热炉基本是烧煤粉,由于炉头烧急火,强化供热,最高温度可达1400℃,造成均热段炉顶及压下部分易烧坏,而且在生产操作上稍有不慎会使钢坯表面烧化,产
With the close cooperation of scientific research, design and construction units, Shanghai No. 8 Plant will vaporize and cool a furnace bottom heating pipe to an anhydrous cold-rolled rail heating furnace, supplemented by automatic thermal control. After more than one year of production practice, the factory workers’ masters have groped their operating experience and continuously improved, and they have achieved good results with high output, high quality, and low consumption, and have made new contributions to the development of steel production. The furnace before the transformation is basically a pulverized coal powder. Because of the burning of the burner, the heat is increased and the maximum temperature is up to 1400°C. This causes the top of the soaking section and the pressing part to burn out easily, and there is a slight difference in the production operation. Be careful to burn the surface of the billet.
