钢筋混凝土用热轧带肋钢筋是我国钢材用量大、生产厂家最多的钢筋中的一个品种。1997年生产约1500万吨,约占钢材产量的15.5%。这种钢筋被广泛地用在建筑工程中,该钢筋的国家标准号为 GB 1499-91。近年来,为了使钢产品能与国际接轨,我国积极采用国际标准。为满足建筑部门对热轧钢筋的质量要求,结合钢铁企业的产品结构,调整生产工艺和充分利用我
Hot-rolled ribbed steel bars for reinforced concrete are one of the largest steel bars in China, with the largest number of steel manufacturers. In 1997, it produced about 15 million tons, accounting for 15.5% of steel production. This rebar is widely used in construction projects. The national standard number of the rebar is GB 1499-91. In recent years, in order to align steel products with international standards, China has actively adopted international standards. In order to meet the quality requirements of the hot-rolled steel bars in the construction sector, and in combination with the product structure of the iron and steel enterprises, the production process was adjusted and full use of me was made.
