余热处理钢筋是一种高效节约型钢材,在国外已被广泛应用。介绍了西班牙轧钢公司大西洋厂(Celsa Atlantic)和希腊哈利沃尔吉厂(Halyvourgiki)的高强度低成本热轧带肋钢筋的生产设备、工艺、产品的品种与质量要求及应用情况。两厂都普遍采用了淬火+自回火工艺生产余热处理钢筋,钢筋在使用中允许焊接,可用于抗震结构。提出国内应加强余热处理钢筋应用的配套技术研究,促进余热处理钢筋在国内的应用。
Waste heat treatment of steel is a highly efficient steel, has been widely used abroad. The production equipment, process, product variety and quality requirements and applications of high strength and low cost hot rolled ribbed steel bars at the Spanish rolling mills Celsa Atlantic and Halyvourgiki in Greece were introduced. Two plants are generally used in quenching + self-tempering process waste heat treatment of steel, steel allows the use of welding, can be used for seismic structure. Proposed domestic should strengthen the application of waste heat treatment of reinforcing steel technology research to promote the application of waste heat treatment of steel in the country.
