攀钢引进西德麦索公司TN钢包喷粉技术的目的是为了解决目前大量生产的重轨钢,D60炮弹钢、大口径弹药筒钢、高压氧气瓶钢和车轴钢中部分产品低倍夹杂和横向冲击值检查不合的问题。同时也为了适应今后低合金钢生产的发展和二期工程对炼钢连铸坯质量的要求。决定引进西德的TN装置,主要是考虑到攀钢的具体条件。据了解瑞典的SL喷粉设备最大只适用于100t以内的钢包,而攀钢120t氧气顶吹转炉出钢量在120～140t,故选择TN装置比较合适。
The purpose of Panjin Steel’s introduction of West Ladissoe’s TN ladle dusting technology is to solve the problem of low-rate inclusions in heavy-gauge steel, D60 shell steel, large-caliber cartridge steel, high-pressure oxygen cylinder steel and axle steel currently being mass- Lateral impact value check the problem. At the same time also in order to adapt to the future development of low-alloy steel production and the second phase of the quality of steel billet requirements. Decided to introduce West Germany’s TN plant, mainly taking into account the specific conditions of Panzhihua Iron and Steel. It is understood that Sweden’s SL dusting equipment is only applicable to the largest ladle within 100t, and Panzhihua Iron and Steel 120t oxygen top-blown converter in the amount of 120 ~ 140t, so the choice of TN device more appropriate.
