(2) Due to the metal type and core non-consistency, in order to facilitate the removal of castings and extraction type, the casting inclination of stainless steel castings should be larger than that of sand castings, generally 30%-50%, it should be noted that: casting In addition to the type of alloy and the height of the wall, the degree of slope is also related to the position of the surface of the casting. Any surface of the casting that has a tendency to detach from the surface of the metal when the casting is cooled and contracted can be designed with a small slope and shrink in the casting. The surface of the casting that tends to be pressed against the metal mold should be given a large inclination, and the casting inclination of the stainless steel casting of various alloys;
(3) Due to the rapid heat dissipation of the metal type, the minimum wall thickness of the <a href="https://www.dz-machine.com/">Stainless steel casting</a> should be larger than that of the sand casting casting, and the minimum wall thickness of various casting alloys and castings of different sizes;
(4) The thickness of the inner wall and inner rib of the stainless steel casting casting should generally be 0.6-0.7 of the thickness of the connected outer wall. Otherwise, since the inner wall (rib) is cold, the crack is likely to occur at the intersection of the inner and outer walls when the casting shrinks.
