Guangdong carbon steel casting150KGThe carbon steel precision castings can be cast, but the engineering cost is relatively high. If the demander does not hesitate to pay, he can choose fine casting. Generally, fine casting production technology is used. At present, the more common small castings on the market account for the majority.

In the production of relatively large Guangdong carbon steel castings, trachoma and pores often appear. The editor summarizes the following solutions:

1：The generation of trachoma can be controlled by spraying paint, improving the compressive strength of sand molds, rigorous modeling, and buckling the box.

2: Complete deoxidation of the molten steel before pouring, control the moisture content of the molding raw materials, prevent the slag from entering when casting Guangdong carbon steel castings, the cavity and the core exhaust pipe are smooth, the pouring temperature, speed, and time The generation of pores can be controlled by controlling and formulating effective processing techniques.

The preheating before welding of Guangdong carbon steel casting is avoided when welding medium carbon steel by electric welding The most effective processing countermeasures to cause cracks. Preheating can not only reduce the cooling rate of the connector, and thus avoid Causes martensite, and can reduce welding stress and accelerate the diffusion and escape of hydrogen. In most cases, it is necessary to preheat and maintain the interlayer temperature. The selection of preheating temperature and interlayer temperature lies in the carbon equivalent of the stainless steel sheet, the thickness of the base material, the rigidity of the structure, and the type of welding wire.
