LFC casting quality than traditional sand casting surface finish, dimensional accuracy and internal quality, no coarse sand casting generally often occur, up boxes, boxes and partial dislocation core and other defects.

At present, the domestic high-temperature alloy castings casting method, are still stuck in the precision casting, casting weight does not exceed the maximum of 4kg, casting temperature below 800 ℃.

Sand casting is a casting method, mainly for sand casting foundry casting mold manufacturing method and core sand, sand casting can be divided into: sand manufacturing, manufacturing core, combined boxes, pouring.

Cast steel is a kind of alloy, it sees iron and carbon as the main elements, carbon content is 0-2%. Cast steel is divided into cast carbon steel, low alloy steel casting and special steel casting 3 classes.

Castings are workpieces made by a special processing technology. Quenching is an important process of steel processing. So, What are the technological index of the quenching steel casting?
