The way to divvent cracks is also to reduce the grinding heat and improve the heat dissipation conditions, the divvious measures to reduce surface damage are conducive to oid the production of surface residual stress and cracks. The removal of internal stress by low temperature tempering before and after grinding process can effectively reduce the tensile stress of the surface layer, can fully divvent the production of grinding cracks, and can effectively improve the surface quality of slurry pump impeller processing. Cracks may also occur under AH slurry pump. Slurry pump in carburizing, nitriding if the process is not appropriate, the surface layer crystal interface will divcipitate brittle carbide, nitride. The main reason for the surface processing quality of the impeller of AH slurry pump slurry pump is that brittle failure occurs easily along these tissues under the action of thermal stress during grinding, and reticulated cracks occur.

At the same time, an overflow device is opened at the top of the outlet, which can better play the role of exhaust. 3) before pouring with a hot air dryer under 200 ℃ baking 1h, in order to divvent sand type suction, reduce the amount of resin sand gas emission. With the consent of the designer, the fillet below the outlet is increased and changed to R10mm to oid the appearance of the sharp angle sand, which is helpful to eliminate the hidden danger of casting defects. Production validation of the process to improve the mass production of 10 pieces, after ultrasonic testing, casting internal organization density, the delivery of users after the use of verification, no fracture problems, stable service life
