How to adjust the fire of stainless steel casting?

Stainless steel castingIt is a casting method compared with the traditional casting process, it can get a more precise appearance and higher casting precision. The more extensive method is: the first abrasive tool made in accordance with the product regulations, cast wax by casting, to obtain the initial wax mold; repeat the coating and sanding process on the wax mold, solidify the shell and dry; The wax mold is melted to obtain a concave mold for dewaxing; the shell is fired to obtain sufficient compressive strength;Stainless steel castingMetal composite materials required for casting; sand is removed after molting, and then high-precision finished products can be obtained, and heat treatment and cold processing can be carried out according to the needs of the goods. Let’s talk about how to adjust the furnace fire when casting precision castings.

It is necessary to increase the casting temperature moderately. Although the liquid condensing increases after the casting temperature is increased, it is helpful to clean up the slag and air ports. The in-depth adjustment of the triangular white mouth of the casting sequence is very traditional, but it is easy to use and convenient, which is very beneficial to the rapid discrimination between the professional and technical personnel and the employees in the actual operation outside the furnace. If the size of the triangle white mouth is associated with the creation effect, the full-phase structure, the thermal analysis curve and the physical properties, it will be beneficial to the online adjustment of the quality of cast iron. Analysis of thermal analysis curves, creating effects with successive subcooling ratio adjustments. This method has been used in Germany and is associated with metallurgical industry quality standards, number of eutectic clusters, and ductility modulus.

In the testing of elastic molds and internal stress; high carbon equivalent, high toughness, high bending stiffness, and low stress are the key requirements for high-end and high-precision CNC lathe casting materials. The use of a complete set of processes for the production of high-end machine tool castings can achieve the quality standards of high carbon equivalent, high toughness, high bending stiffness, and low stress.
