It seems that the forging process such as aluminum alloy casting, aluminum alloy casting, sand casting, etc., all in the whole process of consumption, it is necessary to persevere under a special temperature working pressure natural environment, if the temperature is unqualified, it will endanger the final actual casting. The effect, the analogy is that sand casting, in which range should his temperature be manipulated?
The low-pressure casting hub machine has a compressive strength of 150 MPa, a compressive strength of 150 MPa, an elongation of 3%, and a Brinell hardness of HBS 785. The compressive strength of the metal casting is 310 MPa, and the compressive strength is 171 MPa. The rate is 2%, the Brinell hardness is HBS 885; the compressive strength during centrifugal casting is 340MPa, the compressive strength is 171MPa, the elongation is 4%, the Brinell hardness is HBS 785; steel number = ZCuSn10Pb1 σb\ MPa = 310 δ5\%=2 Strength\HB=885.
Operating temperature range: ~290 °C. Component = constituent element ratio (%): phosphorus P: 0.6 to 1.3; tin Sn: 9.0 to 11.5. Features and application = Cu capacity; casting method: J; 12-1 tin bronze; high strength, good wear resistance, not easy to cause seizure problems, good casting characteristics and drilling production and processing characteristics, in the air and talking water Excellent corrosion resistance. Wear-resistant components for working under high loads (below 30 MPa) and high drag rates (8 m/s), such as crankshafts, bushings, shaft wheels, etc.
The temperature control of sand casting will be mentioned here first. In future news reports, people will explain the temperature post request for forging process such as aluminum alloy casting and low pressure casting. If you have any doubts, please contact Qinhuangdao. Hongtong Machinery Co., Ltd.
