国家建筑钢材质检中心在实施国家和部门下达的产品质量监督抽查检验等任务的同时,对钢筋混凝土用热轧带肋钢筋(习惯称为“螺纹钢筋”,以下简称“钢筋”)生产、流通及质量状况作了一些调查。现针对劣质钢筋的生产、流通现状,提出几点建议,供有关部门参考。 1 国内钢筋生产概况钢筋是工程建设中最常用的材料,也是产量最大的钢材品种之一。近几年来,我国钢筋生产有了长足的发展,产品质量逐步提高。1991年全国钢筋产量在650万t以上,1992年估计可达900～1000万t。在全部产量中,
The National Construction Steel Material Inspection Center conducts production and circulation of hot-rolled ribbed steel bars for reinforced concrete (commonly referred to as “threaded steel bars”, hereinafter referred to as “rebar”) while implementing tasks such as product quality supervision, spot checks, and inspections issued by countries and departments. And the quality of the situation made some investigations. The current situation of the production and circulation of inferior steel bars is proposed to provide suggestions for relevant departments. 1 Overview of Domestic Rebar Production Reinforcement is the most commonly used material in engineering construction and is also one of the steel products with the highest output. In recent years, China’s steel production has made considerable progress, and product quality has gradually increased. In 1991, the national production of steel bars was over 6.5 million tons, and in 1992 it was estimated to reach 9-10 million tons. In total production,
