Chuangyi Metal's professional technical team tells you the control of temperature and speed during aluminum alloy low-pressure casting

The low- temperature casting temperature of aluminum alloy is actually the temperature at which the metal in the liquid state is injected into the crystallization equipment in the holding furnace to maintain its fluidity. Many modern aluminum alloy castings have used degassing and filtering equipment. However, time has proved that the effect of degassing equipment will vary depending on the temperature of the aluminum alloy. Therefore, when using degassing equipment, to achieve a certain effect, the temperature of gravity casting of liquid aluminum alloy needs to be considered. . It is also necessary to consider that the casting temperature is too low, and the gas in the crystallization equipment of the aluminum alloy liquid has overflowed before it can float, so it is easy to cause the generation of pores, which easily causes defects in the product. It is scientifically pointed out that the aluminum alloy entering the crystallization equipment The crystallization temperature of the liquid is tens of degrees higher than the casting temperature. 1445331993253719.jpg
In continuous aluminum alloy casting, the time to produce the finished product is called the casting speed. The speed of low-pressure casting of aluminum alloys is elastic. Actually, it is not a speed when starting casting and casting. The speed of the casting speed will affect the quality, resistance and performance of the product, so if you want to ensure the quality of the product, you must use the highest casting speed. The modern elastic manufacturing speed is determined according to the characteristics of the produced alloy and the size of the required product. It is very user-friendly, so the quality of the manufacturing is also quite good.
