Induction slag centrifugal casting is a casting process that uses electric induction furnace melting technology for metal liquid pouring. During the pouring process, the role of centrifugal force is used to make the molten metal adhere to the inner wall of mold as soon as possible. The thin-walled castings such as impellers, cylinder liners and pistons obtained can directly meet the requirements of the use environment.
Induction slag centrifugal casting has the advantages of good quality and high production efficiency. Compared with traditional pouring processes such as manual casting and gravity casting, the advantages of induction slag centrifugal casting are very obvious. The molten steel obtained by electric induction furnace melting is very pure, the pouring temperature is greatly lowered, and the castings produced have less defects and are more beautiful in appearance. At the same time, the production efficiency is also greatly increased compared with traditional pouring processes.
The main feature of induction slag centrifugal casting is the use of centrifugal force as a pouring force. The centrifugal force is generated by the rotation of the mold and the die holder in the pouring process, enabling the molten metal to solidify on the sidewall and form a thin casting wall. In the traditional casting process, this process is usually done under the pressure of the molten metal itself and the air pressure is lost. The centrifugal force greatly reduces the phenomenon of air bubbles being formed in the die wall, making the casting wall more clean.
At the same time, induction slag centrifugal casting has the advantage of good mould filling performance. Experiment shows that when the mold rotates at a certain speed and the flow of the molten metal and the centrifugal force acts synergistically, the molten metal forms in the mold Will form a higher liquid back pressure, the high liquid back pressure will push the molten metal into the mold, even in the blind hole and corner, the molten metal will completely fill in and form a good casting quality.
In summary, induction slag centrifugal casting process has the advantages of high production efficiency and good production quality. It can be used in the production of thin-walled castings such as impellers, cylinder liners and pistons, and it is sure to be widely used in the machinery manufacturing industry.
