How to prevent the defects of tin bronze plate? The defects of the tin bronze plate are mainly manifested in the unreasonable design of the casting structure,Tin Bronze sharp corners,Tin Bronze excessive wall thickness changes of the casting, poor retreat of the sand mold (core), local overheating of the mold, excessive pouring temperature,Tin Bronze and removal of the casting from the mold Too early; the heat treatment is overheated or burned, and the cooling rate is excessive.
Prevention of defects in tin bronze plate castings: improve the structural design of the castings,Tin Bronze avoid sharp corners, strive for uniform wall thickness,Tin Bronze and smooth transition; take measures to increase the sand mold (core) retreat; ensure that all parts of the casting are solidified at the same time or sequentially,Tin Bronze and improve pouring System design; appropriately reduce the pouring temperature;Tin Bronze control the cooling time of the mold; use the thermal correction method when the casting is deformed;Tin Bronze correctly control the heat treatment temperature and reduce the quenching cooling rate.
