Resin coated sand casting has a long history in the field of casting, and the output of casting is quite large, but there are many problems when using resin coated sand casting to produce precision steel castings, such as sand burn, cold shut, and air hole. How to solve these problems remains to be explored. […]
High chrome cast iron containing 12.30% chrome and 2.4-3.6% carbon can be highly alloyed and heat treated to obtain martensite or austenite or mixed matrix and special carbides of chrome. This particular carbide is a hexagonal system of Me7C3 with hardness as high as HVL200. 1600, much higher than the cementite type of carbides and common mineral […]
The microstructure and properties of cast iron depend on the microstructure and quality of raw materials to a great extent. The use of recarburizer is very important, especially for cylinder block and head castings with high densification requirements.
1. CHARACTERISTICS OF MEDIUM FREQUENCY FURNACE MELTING The Medium frequency induction furnace is suitable for melting various brands of molten iron, to meet the composition, temperature of molten iron, to meet the performance requirements of all kinds of molten iron. It’s very adaptable.
Forced by the current situation, many foundries that produce small and medium-sized castings all want to invest in automated casting workshops, but suffer from lack of experience and lack of corresponding professionals So there are many blind, blind, inadequate preparation, unreasonable workshop design, too low operation rate, poor casting quality, management chaos, and even automation […]
