The research work mainly serves the ZHY casting technical transformation project and takes meeting the process production requirements as the basic goal. Therefore, there are some problems in the project research work, such as insufficient in-depth and comprehensive exploration and analysis, and the test and research results need to be further verified in mass production. Therefore, the following development directions are put forward:
(1) The relationship between molding sand performance and molding sand composition, ambient temperature and humidity, understand the working principle of molding sand performance online measurement and control system, and independently develop molding sand performance online measurement and control system;
(2) The original process of hook tongue product has the problems of low feeding efficiency of riser and waste of some liquid steel. The optimized process has solved the above problems, and the simulation results are good. After purchasing a new mold, it needs to be tested in actual production;
(3) In addition to casting cracks, a large number of welding cracks and heat treatment cracks appear in the mass production of hook body and hook tongue. It is necessary to explore and establish systematic post-treatment (machining, welding repair and heat treatment) process specifications to meet the production requirements of green sand steel castings, so as to maximize the production efficiency.
