Stainless Steel Precision Casting

1. What is the temperature control of stainless steel precision casting

Stainless steel precision casting can effectively ensure that the melt has good fluidity during transfer to a certain extent. The temperature selection of stainless steel precision casting should be effectively determined according to the transfer distance and transfer process to reduce temperature and flow.

Due to its small transition zone size, stainless steel precision casting has good mechanical properties during use, which can meet its fluidity to a certain extent and does not form bright crystals. The general temperature is 715~740℃. Stainless steel precision casting flat ingots have a high tendency of hot cracking, and the temperature of stainless steel precision casting is relatively low, generally 680~735℃.

The crack tendency of stainless steel precision casting round ingot is relatively low, which can effectively ensure that the alloy has its good exhaust gas feeding ability to a certain extent, effectively create its sequence close conditions, increase the density, and the casting temperature is generally higher. , The casting temperature of ingots with diameters above 350mm is generally 730~750℃.

2. What is the dimensional accuracy of stainless steel precision casting?

Stainless steel precision casting requires high dimensional accuracy, which can effectively reach CT4-6 in general. Due to the complex Investment Casting process in the product, there are many factors that affect the dimensional accuracy of the casting, such as the deformation of the investment and the shell Heating, shrinkage of mold material, etc.

The alloy shrinkage rate of stainless steel precision casting and the deformation of its castings in the process of stainless steel precision casting. Although the dimensional accuracy of ordinary investment castings is relatively high, it needs to be improved in order to achieve consistency. The size and surface quality of stainless steel precision casting castings are higher than other casting methods, and more complicated than other casting methods. The products are resistant to high temperatures during use and are not easy to process. The products can be directly used. Cast by investment casting.

The dimensional accuracy of stainless steel precision casting is generally very accurate, mainly depends on how we choose the appropriate accuracy.

3. What are the advantages and disadvantages of stainless steel precision casting?

In the production of stainless steel precision casting products, some products have weird shapes and cannot be produced by bending pipes and other processes. Such irregularly shaped products are produced. Wax molds→sand molds→liquid materials are used for filling and molding. Craftsmanship.

Stainless steel precision casting process. It is a low-cutting or no-cutting casting process. It is an excellent process technology in the foundry industry. It has a wide range of applications and is not only suitable for casting of various types and alloys.

Advantages: According to different wax models, make products with various styles.

Disadvantages: The precision of the formed blank is not high, and the surface roughness is also great.
