Product Details
There are many kinds of casting technology, including sand casting, gravity casting, pressure casting, melt casting and so on. As one of the bases of modern machinery manufacturing industry, casting has a history of thousands of years. Because of the precipitation of time, the casting process has become an extremely complex process, and each casting process has its own process specification.
Here is to introduce the sand casting process.
1. Confirm casting drawings, including size, material, precautions, etc., as well as preliminary work.
2.The feasibility of using CAE to simulate the casting process in Leiyang is discussed. The defects such as shrinkage cavity, air hole, cold shut and so on are prevented, and the time and economic losses are caused by repeated furnace return.
3. Casting wood mold production and pit modeling, for casting molding.
4. Smelting, melting and purifying molten steel to remove impurities in molten steel. Heavy industry uses LF refining furnace and VD vacuum degassing furnace to purify molten steel, which can effectively improve the quality of molten steel and the performance of castings, and meet the high-end casting needs of users.
5. The composition of the casting is detected, and the material composition of the casting is detected by spectral analysis to ensure that the casting meets the needs of users.
6. Casting and cleaning of castings.
7. Heat treatment, some castings need heat treatment, quenching and tempering, which can improve the physical and chemical properties of castings
8. Inspect the castings to ensure that they are impeccable. Leiyang has seven testing systems, including: chemical composition testing, mechanical testing, metallographic analysis, NDT testing, molding sand testing instruments, hardness testing instruments, three-dimensional and three-dimensional testing. Among them, non-destructive testing follows two levels of UT and Mt.
9. According to customer's demand, provide casting machining service. The machining workshop owned by Leiyang can carry out CNC processing. It has CNC gantry boring and milling machine, CNC Floor Boring and milling machine, CNC vertical lathe, boring and milling machine, radial drilling machine and other equipment, providing the overall solution from the blank steel castings to the finished products.
