摘　　要：为进一步开发国际钢材市场 ,研制开发了符合加拿大可焊性高强度钢筋标准要求的高强度钢筋。制定了化学成分及力学性能内控标准 ,分析了生产工艺各环节对成分和性能的影响 ,依据试验结果 ,在全面统计分析的基础上 ,调整了冶炼成分 ,生产的 5 3 1批钢筋全部合格。通过直方图及回归分析 ,说明了制定的产品生产工艺可行 。For exploiting international rolled steel market farther, the weldable high strength reinforced bar were developed according to Canada standard. Through establishing internally controlled standard of chemical composition and mechanical properties, analyzing the effect of productions and processes on compositions and properties, all products of 531 batches with qualification have produced on the basis of analyzing and adjusting melting composition. The practice has proved that the production process for producing this product is feasible and it provides a basis in theory for production in the future.
