1 前言棒材厂是在原一炼钢转炉车间基础上于1981年改造投产的棒材生产单位,设计φ12～φ25mm规格,二火成材,年产10万吨。1997年产量20万吨,1998年初进行简易一火成材改造,实现用130~2连铸坯一火生产φ16～32mm的圆螺钢筋。现年产能力已达30万
1 Introduction The bar mill is a bar production unit that was put into operation in 1981 on the basis of the original steelmaking converter workshop. It has the specifications of φ12 ~ φ25mm and the fire of the second generation, with an annual output of 100,000 tons. In 1997, the output was 200,000 tons. In the beginning of 1998, a simple fire improvement project was carried out to realize the production of φ16 ~ 32mm round spiral steel bar with a fire of 130-2 continuous slabs. Now the annual capacity has reached 300,000
