Dongfang Turbine Co.,LTD Production Process Optimization Of The Reheat Steam Turbine

This thesis to reheat unit production process optimization scheme of program analysis theory of the industrial engineering and concurrent engineering theory as the foundation, according to common problems in the industrial turbine division production organization:long technical preparation period, blank purchase production cycle is long, purchasing blank to lag, most sets of wood pattern to design tooling, department of processing and manufacturing cycle is long, assembly and debugging the delivery cycle is long, users than stop witness point in the process of production, set of product quality and unit has quality problems, most of the project can’t meet the demand of users, production load imbalance, key resource load weight. In order to solve the industrial turbine group production organization in the process of the above problem, improve production efficiency and product quality, this article from the production preparation process and the basic production process of these two aspects of industrial turbine division production organization process optimization.In the stage of production preparation process:adopt the mode of parallel operation, the technical preparation and production preparation at the same time, the design department issued by the white figure and contact list to determine blank size, weight, material, specifications, etc., used for purchasing department to order blank, technology department according to the product white figure tool, tooling design, the production department to tools and fixtures blanking and blank preparation of raw materials, etc.In the basic stage of the production process, production planning, production schedule control, through the formulation of shift the machine operation plan, inspection plan, process route adjustment and optimization measures, in order to shorten the parts inspection time, user witness, product process transfer number, product storage and waiting time, product processing and manufacturing cycle, etc.This article through to reheat unit production organization after process optimization, reheat unit cylinder processing process, for example, to validate the optimized effect, shorten manufacturing time 18 days. Production organization process of reheat unit significantly shortened, improvement effect is very obvious.
