本钢第二炼钢厂,转炉上氧枪与输氧管之间联接,原设计为橡胶软管,投产以来,多次出现爆炸现象,严重影响了炼钢生产,并直接威胁人身设备安全。针对这一问题,与南京晨光机器厂合作,将大口径金属螺旋软管应用到炼钢生产。试验结果证明,金属软管具有重量轻、耐高压、耐腐蚀、抗老化等优点,使用寿命已达1.2万次,效果显著。可供转炉钢厂推广使用。
The second steelmaking plant in Benxi Iron and Steel (Group) Co., Ltd. was connected with the oxygen lance and the oxygen inlet pipe. The original design was a rubber hose. Since the commissioning, many explosions have occurred, seriously affecting the steelmaking production and directly threatening the safety of personal equipment. In response to this problem, we cooperated with Nanjing Chenguang Machine Works to apply the large-diameter metal spiral hose to steelmaking. Test results show that the metal hose with light weight, high pressure, corrosion resistance, anti-aging, etc., the service life of up to 12,000 times, the effect is significant. Converter for the promotion of steel mills.
