Q:Explain the heat treatment effect of casting parts, forging parts and welding parts

2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.

Q:What's the density of the cast iron? The density is thin and the density is thin

Generally cast iron thick place, density is empty, thin place density a little more.

Q:How to calculate the price of casting parts?

According to the complexity of the workpiece, material and casting requirements and process yield

Q:How to cast iron and wrought iron collocation

2, listen: Pig beating sound boring, wrought iron beating sound loud.

Q:How to get rid of casting sand inside casting parts?

Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!

Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?

Proofing refers to making the first sample to confirm to the customer

Q:What's the effect of casting copper?

Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.

Q:Why does the surface of stainless steel casting mirror mirror ripple?

The surface can be improved by a little more than Xiasha

Q:The casting defects of pores, trachoma how to repair?

If the repair after the high temperature resistance, choose LT737 high temperature repair agent.

Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?

Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
