摘　　要：从影响钢铁企业工序质量和产品质量的因素出发,按照统计过程控制的原理实施三个质量工序评价,有步骤地开展上工序满意度评价、产品实物质量评价和本工序自我评价。实践证明,开展这一活动可以针对产品质量和工序质量中存在的问题,全面、客观、准确地分析原因,及时采取纠正预防措施,从而不断提高产品实物质量,将质量损失降至最低。Starting from the factors of effecting procedure quality and production quality, according to the theory of statistic process controlling, the three process quality evaluates including evaluate of previous working procedure, evaluate of product quality, self-evaluate of working procedure are developed step by step. The practice has proved, aiming at the problems existing in production quality and process quality, the reasons are analyzed generally, objectively and exactly, and preventive measures are adopted in time, then the production's practicality quality are improved continuously, and the quality losing are reduced to the lowest limit.
