Application Of Six Sigma Management In Reducing The Proportion Of Non Steady Billet In Steel Making Process

Shougang Jingtang United Iron&Steel Co.,Ltd.(hereinafter referred to as"Jingtang Company")is located in Tangshan City,Hebei Caofeidian,an important carrier of the relocation of Shougang,it is important with the process lines,including iron,steel,hot-rolled,cold rolling and the like.Jingtang steel,designed to produce 9.7 million tons of steel,the main products include slabs,low carbon steel,high-strength steel.Six Sigma is to improve product quality,improve weapon manufacturing operations,practice has shown that a large number of applications,highlighting the role of Six Sigma "improve the quality,increase efficiency," respect.This topic through theoretical research Six Sigma to identify and implement the import base path of Six Sigma,Six Sigma import and project implementation research,through the Six Sigma define,measure,analyze,improve,control the path of Six Sigma to solve problems,find the impact of steel the main quality steel billet causes unsteady,and by mathematical statistical analysis methods to determine the improvement plan,and combined with steel-making management system to maintain project results,thus reducing the proportion of steel billet unsteady,reduce quality objection reduce Jingtang company unsteady due to the economic losses caused by the blank.The study of this subject,after large-scale iron and steel enterprises will steelmaking process management features and how to combine the state-owned iron and steel production characteristics,into the implementation of Six Sigma,how to use Six Sigma to improve steel quality of management,how to Six Sigma project results into the daily management plays the demonstration and guidance.
