Precision Precoated Sand Casting Steel Parts

Cast steel is a kind of excellent high temperature performance of precoated sand and casting performance of new products of precoated sand, cast steel with high strength of precoated sand, good liquidity, curing speed, more content of SiO2, strong resistance to high temperature, low gas evolution, liquidity is good wait for a characteristic, is a widely used in joint valve shell, buffer, steel shaft, the modelling of engineering excavators, such as pieces of container Angle steel material. 1, vibration deoxidization, high strength, low gas, low expansion; 2, good, high casting surface finish; 3, can't afford to shell mold layer, good thermal stability, good thermal conductivity, good liquidity, the casting surface smooth; 4, high strength, high temperature resistant, low expansion, . Good demoulding, good resistance to adhering sand; 5, uniform shell hulling, curing speed; The influence factors of casting sand casting cost: There are many factors affect the cost of sand casting. Here, we list some main factors, and hope these information can help foundry customers. 1. Pig iron and scrap costs Cast steel scarp cast iron and cast steel is the main material, so their price will directly affect the cost of sand castings. 2. The cost of alloy If you need to add some of the alloy such as chromium, nickel, copper and molybdenum, and their prices would have been more expensive than ordinary metals. 3. Casting process different casting process will largely influence the cost of castings. The cheapest is green sand casting process, and resin sand casting is more expensive, pre resin coated sand for casting process (such as hot core and shell molding process) will be the most expensive process. 4. The cost of resin As for the casting by preloaded resin coated sand and resin sand casting process, the resin price will affect the cost of castings, but it will not affect the sand casting process.
