青岛市车辆制造厂的半吨小转炉,在再生式碱性化铁炉的配合下生产情况很正常。该厂的半吨小转炉自1958年10月份投入生产以来,由于设备简陋,技术力量薄弱,因而采取了一边自制设备,一边学习试炼的办法,到今年4、5月份基本走上了正常生产。目前平均日产17吨左右,最高日产达26.36吨,3～5月份共生产了1141.5吨钢,合格率(按含硫计)为100%。根据该厂的经验,由于小转炉炉子小,热量少,散热快,因此要保证小转炉的正常生产必须保证铁水、转炉吹炼和浇注过程的高温操作,必须要在以下几个方面加强:(1)保证铁水出炉温度在1400℃以上。
Qingdao vehicle manufacturing plant half a ton of small converter, in the regeneration of alkaline iron furnace with the production of the normal situation. Since the semi-rotary converter was put into production in October 1958, due to its poor equipment and weak technical power, the semi-rotary converter of this plant has taken the method of self-made equipment and learning trial until April and May of this year and has basically started its normal production . At present, the average daily output of about 17 tons, the highest Nissan amounted to 26.36 tons, 3 May produced a total of 1141.5 tons of steel, pass rate (sulfur content) of 100%. According to the factory’s experience, due to the small converter furnace small, less heat, heat fast, so to ensure the normal production of small converter must ensure that hot metal, converter blowing and pouring process of high temperature operation, must be strengthened in the following areas: 1) to ensure that the hot metal temperature above 1400 ℃.
