前言高强度预应力用热处理钢筋是国内外钢筋发展的重要方向。它对建筑、铁道、交通等部门预应力混凝土构件的生产和发展具有重要的技术与经济意义。前几年,我们参加了沈阳线材厂采用轧热淬火法生产φ8毫米高强度螺纹钢筋的试制工作,现在此谈几点初步认识。 Preface High strength prestressed heat treatment of steel reinforcement is an important direction of development at home and abroad. It has important technical and economic significance for the production and development of prestressed concrete components in the construction, railway, traffic and other departments. A few years ago, we participated in the trial production of φ8 mm high-strength threaded rebar produced by Shenyang Wire Rod Mill by hot rolling quenching method. Now we will talk about a few preliminary understandings.
