| A deep research is made in the thesis to wire rod manufacturing quality control and innovation of iron and steel enterprises. First, the thesis carries on a research to the manufacturing quality blemish, the request of quality examination, the producing characters of each kind of wire rod and the effects on quality control. Second, with analyzing the craft process and the technique characters of wire rod manufacturing, the key problems and reasons are found out in the progress of the quality control. Third, taking Yu Zun Wire Rod Mill of Qingdao Iron and Steel Group Holding Cor. Ltd. for the research object, the model of wire rod manufacturing quality control and innovation based on the theory of the " Five Day " Whole Charge Management, is set up and the concrete implement measures are put forward. Fourth, the thesis builds evaluation index sign system and evaluates the model of the wire rod manufacturing quality control and innovation, and carries on analyzing and evaluating the concrete implement acquisition of the the model of wire rod manufacturing quality control and innovation based on the theory of the " Five Day " Whole Charge Management.The main research results and conclusions are as follows:1 .The thesis introduces the general theories of the wire rod manufacturing quality control, and manufacturing quality control method of each kind of wire rod . The quality control method of the factors of the steel such as the internal organization, chemistry composition, the physics function, and so on.2. According to the craft process and the technique characteristicses, the thesis analyzes the present condition of wire rod manufacturing quality of Yu Zun Wire Rod Mill of Qingdao Steel, and finds out the negtive reasons on quality control.The main reasons of the flexitible product quality exist in the personnal, management, craft, equipment, raw material and the packing, and then the thesis puts forward that the technique innovation should be directed in reforming and improving the equipments... |
