The heat treatment technology of beilun aluminum die casting
The traditional method of aluminum die casting is not only expensive, but also consumes the most energy. There are several separate steps for these furnace foundry processes, each of which is irrelevant to the previous steps. The department of energy and the American materials association, in a forward-looking conference on industrial production manipulation, said: "the process of aluminum die-casting heat treatment can achieve energy conservation."
According to the statistics of the relevant departments, the new model made in the year of zero year, the whole aluminum portion of the electric furnace cast aluminum is about 80 percent of the total population of the whole country, and the average is about 118kg. In the next few years, the number in the rapid promotion, 8 to 10 years later, the future is expected to improve the schedule, at the same time with the proportion of aluminum and aluminum engine cylinder small cars will soon be reached to ninety-five percent.
Aluminum casting continues to produce the working skill of combining the traditional heat treatment furnace casting post-treatment process mainly includes the rapid cooling, to improve the tube, mechanical sand mold/core and artificial to wash, and then heated, tunnel furnace, casting and heat treatment. Traditional foundry techniques include vanishing molds, retaining the precision of the mould, and compacting the sand. These independent devices require more management operations, including transportation appliances that damage the castings, and increased equipment and manoeuvring require additional manpower, production space and energy.
