1.First of all, matching with the product should be considered when choosing the production line of the sand-coated iron mold. 2. Iron sand-coated production line should have: A high-quality iron sand-coated production line must have the primary factors of the high running rate of equipment, mature technology, high rate of the genuine product.
1. Take a pinch. 2. Exhaust. 3.Slag collection. 4.Logo for the metal filling cavity. Casting riser is a part designed to supply the shrinkage of casting during solidification to prevent shrinkage cavity and shrinkage porosity.
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 […]
This company is a large state-owned enterprise, the production of many varieties of gray iron castings, the previous use of Cupola melting equipment, the production of gray iron castings have been very stable quality. In order to further implement the national requirements for Energy Conservation and emission reduction, optimize the environment, and achieve high efficiency […]
In the traditional production process of ductile iron, about 10% carbon scrap is generally used for the burden. This paper only deals with some problems that should be paid attention to in the process of producing nodular cast iron in an induction furnace after increasing the proportion of carbon scrap used. According to the production […]
Heating Temperature 200-300, curing time 30-150s, shot pressure 0.15-0.60 MPA. The sand core with the simple shape and the resin coated sand with good fluidity can select lower shooting pressure, lower heating temperature for thin sand core, longer curing time when the heating temperature is low. The resin used in coated sand is phenolic resin. […]
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. […]

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.
