Research On The Working Procedure Quality Control Of SWA Melting And Casting Plant

With the spread of TQM idea and ISO9000 series standard in many big enterprises in our country, this theory of the working procedure quality and control have been the core of enterprise control. The theory is part of TQM. It represents TQM's soul of total, complete process, every person participation, emphasize particularly on the efficient method of working procedure management and control in product manufacture. It will directly affect the quality of products.Keeping to the TQM idea, take the working procedure quality control as the center, regarding working procedure process management (macroscopic) and process control (microscopic) two master lines, In the background of SWA Melting and Casting Plant. First introduced the theory and its related research carried on the working procedure quality control, Then analysised the existing status on the procedure process management, procedure process control and product quality in the Melting and Casting Plant, Pointed out that the main quality problem is the crack and slag of ingot. Using the SPC tool ( fishbone chart, histogram, control chart and so on ) analyzed the main question which in the working procedure process management and the process control existed. In the working procedure progress management, lack of standard and quality consciousness, the quality control system becomes a mere formality and so on. In the working procedure process control, the various working procedures element (5M1E) control is asthenia. Constructively proposed some useful measure. For example, Enhancing the working procedure process, implementing the TQM idea, improving the quality management system continually in the working procedure management, Perfecting working procedure quality control condition, establishing essential working procedure quality control point, introducing and using statistics technology and so on. Finally, analysised its implement- tation effect.
