Box type quenching furnace, also known as hard die forging or durable forging, is the smelted aluminum alloy poured into the metal mold to obtain the casting method, aluminum alloy solid furnace box type quenching furnace people mostly choose metal core, but also can choose sand core or shell core and other methods, compared with pressure forging, aluminum alloy solid furnace residual type long service life.
(1) Forging advantage
Metal mold cooling speed is faster, casting structure is more fine, heat treatment can be strengthened, mechanical properties than sand mold forging 15% higher.
Box quenching furnace, casting quality is stable, surface roughness is better than sand forging, scrap rate is low.
Good working conditions, high productivity, workers easy to grasp.
(2) Forging defects
The metal type has high thermal conductivity and poor filling capacity.
No air permeability for metal wood body. It is necessary to adopt the corresponding measures to exhaust useful.
The metal type is non-yielding and prone to crack and deformation during solidification.
