我厂建厂时由于钢材紧张,一时无法制作铜质风口大小套,所以开炉时用的是生铁风口大小套。在使用的半年中损坏很大,翻砂又较困难,质量又不能保证,经常供不应求。在这样的情况下,本厂职工大胆革新,采用了钢板焊制风口大小套。几年来的使用情况表明,完全能够保证高炉的正常生产。我厂风口大小套主要采用10毫米的普通钢板焊制。在需加工的局部地方采用14毫米钢板。进出水管在同一侧,中间用隔板隔开,进水管一直伸到内底,以保证高温处得到
Because of steel tension, I can not make copper tuyere sleeve at the time of factory construction, so the size of pig iron tuyere is set when I open the furnace. Damaged in the use of a large six months, turning the more difficult, the quality can not be guaranteed, often in short supply. In such circumstances, the bold renovation of factory workers, the use of steel welding air outlet size sets. Years of use shows that the blast furnace can fully guarantee the normal production. I set the size of the factory outlet mainly 10 mm ordinary steel welding system. In the processing of local use of 14 mm steel. Out of the water pipe on the same side, separated by a partition in the middle, the inlet pipe has been extended to the insole to ensure that high temperatures get
