生产钢筋混凝土用HRB400热轧带肋钢筋时,硅锰合金用量占有较大比率,对钢材成本的影响很大。利用残余铬元素替代0.10%的锰元素,以降低成本。结果表明:产品质量性能满足国家标准要求,HRB400热轧带肋钢筋吨钢合金成本可以降低10元左右。
When producing HRB400 hot-rolled ribbed steel bars for reinforced concrete, the amount of Si-Mn alloy accounts for a large proportion, which has a great impact on the cost of steel. Reduce costs by replacing 0.10% manganese with residual chromium. The results show that the product quality and performance meet the requirements of the national standard. The cost per ton of HRB400 hot rolled ribbed steel can be reduced by about 10 yuan.
