上钢一厂平炉车间自1954年生产沸腾钢以来,迄今已有一年馀,钢锭合格率一般能够达到计划要求;但是原始合格率很低,今年来最为突出,3月份仅达48.66％。因此,不仅不能保证产品的质量,也给人力物力上带来了极大的浪费。造成平炉钢锭原始合格率低的原因,主要是与操作、铸锭工作有关。今年5月在铸锭工作会议上钢一厂曾作过比较系统地铸锭工作报告,有些经验如整洁制度是有参考价值的;但也有些问题,如浇铸速度过快,浇铸温度低等,这是有待于上钢一厂进一步研究迅速采取措施予以解决的。
The steelmaking furnace has been producing more than a year since its production in 1954. The qualified rate of steel ingot can generally meet the requirements of the plan. However, the initial pass rate is very low, which is the most prominent this year, reaching only 48.66% in March. Therefore, not only can not guarantee the quality of products, but also brought great waste of manpower and material resources. Flat blanks caused by the original low pass rate, mainly with the operation, ingot work. In May this year, at the ingot working meeting, the first steel factory made a systematic report on ingot work. Some experiences such as tidy system are of reference value; however, there are some problems such as excessive casting speed and low pouring temperature, This is awaiting further study by the First Steel Works to take swift steps to solve them.
