7075 aluminum bar production has many links, casting is one of them, 7075 aluminum bar manufacturers in 7075 aluminum bar casting need to pay attention to what matters?So let's talk a little bit more about that.

1. Select the correct casting temperature

The correct casting temperature is an important factor for the production of 7075 aluminum bar. 7. Low temperature is easy to produce slag, high temperature pass, and thick grain and feather crystal are easy to occur.

Ultra-micronization model.the processing after 7075 aluminum rod, forging a modest rise in temperature, usually can be controlled between 720-740 ℃, high temperature has a narrower too band, too narrow band is advantageous to the crystallization front eliminate gas evolution, of course the temperature is too high, too high of the forging temperature will narrow the useful time of grain refining agent, become a relatively large grain size.

2.7075 Aluminum bar forging, as far as possible to prevent the turbulence and roll of aluminum liquid, so that the aluminum liquid in the surface oxidation film protection stable capital flow into the crystallizer structure crystallization.This is because the agitation equipment of the molten aluminum oxide film and the flow cause the cutting of all rolled aluminum surfaces to form new oxides while involving the molten aluminum oxide film.

3. Filtrate 7075 aluminum bar aluminum liquid. Filtration is a useful method to remove nonmetallic slag from aluminum liquid.In forging 7075 aluminum rods, multilayer glass cloth or ceramic filter plates are usually used for filtration, regardless of the filtration method.
