What are the precautions for preheating and baking of aluminum chips

Aluminum shavings carry a lot of oil and moisture. Oil and water from the machining process, or other processes (such as in order to improve the uniform failure process of piston parts, the use of oil melt furnace temperature failure process), oxidation corrosion is serious, so should be timely preheating and baking.

The baking temperature of aluminum chips must be determined according to various factors. Too high temperature, not only heat loss, but also cause strong oxidation of aluminum chips. So the general baking temperature should be between 250 ~ 300 degrees.

The simple method of baking aluminum chips is to heat the aluminum chips on the steel plate and bake them until they do not emit smoke. It can also be used to put aluminum chips into the "baking cart", pushed into the drying kiln for baking or aluminum chips into the power frequency furnace, into the cast iron workshop pot baking, so that the oil and volatile at high temperature and combustion, and then smelting.

Aluminum chips preheating and baking can not only remove the oil and water in the aluminum chips, but also shorten the smelting time, while reducing power consumption, can improve the productivity of smelting equipment, reduce the cost of smelting (remelting).
