Casting non-ferrous alloy smelting smelting process have a significant impact on performance and defects nonferrous alloy castings. Most non-ferrous alloys prone pores and inclusions, especially titanium, aluminum, magnesium alloy and some copper alloys. General melting process is: 1) According to Alloy Castings requirements prescribed, can detect the chemical composition range of the alloy selected from the chemical composition; 2) the elements burning rate and composition requirements, compounding calculations, various amount of charge obtained, and select charge. If the charge is contaminated, we need to deal with, to ensure that all of the charge to clean, no rust, and preheated before feeding; and 3) examination and preparation of the utensils, brushing paint and preheat to prevent gas inclusions and harmful pollution elements; and 4) feeding. General order of addition is: scrap, master alloys and metal materials, low melting point metal material easily oxidized, such as magnesium anchor principle was added after melting furnace charge; 5) In order to reduce pollution of the suction and liquid alloy oxidation, as soon as possible melting, to prevent overheating, if necessary, some liquid alloy cover agent to be added protection; 6) After melting the charge anchor repair, refining process to purify the liquid alloy and refining effect of test; 7) if necessary, for modification processing and segmentation process to improve organizational performance, and test the treatment effect; 8) adjust the temperature big anchors, casted. Some alloy to be stirred before pouring, to prevent gravity segregation. Is made more economical methods of rough shape, the shape of complex parts can show its economy. Such as automotive engine blocks and heads, ship propellers and exquisite works of art. Somewhat difficult to cut parts, such as gas turbine parts nickel-based alloy can not be formed without casting method. For casting engineers and mechanical design engineers, heat treatment is a very meaningful, but with very high value method for improving the material quality, by the heat treatment can change or affect the iron anchor organization and the nature, and can get more high strength, hardness, and to improve the wear resistance and the like. Since the purpose is different, very much the type of heat treatment, can be mainly divided into two basic categories, the first category is the organizational structure will not change and does not change through the heat treatment or should happen, the second is the basic organizational structure changes by . The first heat treatment procedures, mainly used to eliminate stress, and this stress is due to the different conditions and conditions caused by cooling in the casting process. Organization, strength and other mechanical properties, which does not change significantly due to the heat treatment.
