前言 攀枝花地区铁矿石属高钛型钒钛磁铁矿,攀钢高炉冶炼产生的炉渣中TiO_2含量达20％以上,具有短渣性能,熔点较高。因此,高炉出铁后,在铁水罐的周转使用过程中,罐口与罐壁粘结了大量的渣、铁粘结物,使铁损增加,铁水罐的有效容积迅速缩小,严重影响铁水罐的周转与高炉生产的正常进行。 1973年炼铁厂曾开发氧气化罐技术以解决上述问题,取得一定效果,但仍存在问题,如无法处理罐口粘结物、低温铁水罐需兑铁水后化罐、环境污染严重等。
Preface The iron ore in Panzhihua is a high-titanium vanadium-titanium magnetite. The content of TiO 2 in the slag produced by blast furnace blast furnace in Panzhihua Iron and Steel Co. reaches more than 20%, with short slag properties and high melting point. Therefore, after blast furnace tapping, during the turnaround of the hot metal tank, a large amount of slag and iron sticking material is adhered to the tank mouth and the tank wall, the iron loss is increased, and the effective volume of the hot metal tank is rapidly reduced, which seriously affects the hot metal tank Turnover and blast furnace production are normal. In 1973, the ironworks had developed oxygenation tank technology to solve the above problems and achieved some results. However, there were still some problems such as the inability to handle the tank mouth adhesive, the low temperature hot metal tank to be repulped by hot metal, the serious environmental pollution and so on.
