Besser - Carbon Steel Casting
Carbon steel castings (also called carbon steel investment casting) are mainly made of iron and carbon. Carbon steel is one of the main materials in the current cast steel industry. It has the advantages of low cost, high wear resistance, easy preparation, and can be heat treated to improve its strength, ductility, and processability.
Classification of carbon steel
Low carbon steel (
Because of its low strength, low hardness, and softness, it is also called soft steel.
Medium carbon steel (0.20 to 0.50% C):
It is the most widely used material in various uses at medium strength levels. In addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts.
High carbon steel (> 0.50% C):
After being properly heat-treated or hardened by cold drawing, high carbon steel has the advantages of high strength, high hardness, high elasticity, and not easy to deform.
Advantages of Carbon Steel Castings
-
Compared with other steels, carbon steel uses the largest amount and is easily obtained by casting.
-
Carbon steel can obtain higher hardness and better wear resistance after heat treatment.
-
The hardness in the annealed state is very moderate, and it also has good machinability.
-
The raw materials of carbon steel are very common, easy to obtain, and the cost of production is relatively low.
Carbon Steel Casting Process
There are currently two processes for carbon steel castings: water glass investment casting or silica sol investment casting
Water glass casting: Water glass is added to the molding material (commonly referred to as silica sand) according to a certain ratio, and it is made into "water glass sand" by stirring, rolling and mixing, and it is blown into the mold and sand box with CO2 gas, CO2 and water. The glass undergoes chemical reaction to form silica gel to harden the water glass sand, and is completed through the processes of mold lifting, box closing, and pouring.
Silica sol investment casting: This is a lost wax casting method. The mold is first made according to the shape of the silica sol cast part; the wax mold is placed in a solution made of silica sol and quartz sand. There will be a layer of material on the wax mold and then it will solidify. After repeated soaking and curing, it is basically formed. Finally, it is dewaxed and cast.
