Box quenching furnace, also known as hard die forging or durable forging, is the way to obtain castings by pouring melted aluminium alloy into metal mold. Aluminum alloy solid melting furnace box quenching furnace mostly uses metal core or sand core or shell core. Compared with pressure forging, the remaining service life of aluminium alloy solid melting furnace is longer.
2, forging strengths
(1) strengths
The cooling rate of the metal mould is faster, the casting structure is finer and can be strengthened by heat treatment. The mechanical properties of the metal mould are 15% higher than that of the sand forging.
Casting quality is stable in box quenching furnace, surface roughness is better than sand forging, and waste rate is low.
Good working conditions, high productivity, easy for workers to master.
(2) shortcomings
The thermal conductivity of metal mold is large and its filling capacity is poor.
Metal wood body has no air permeability. It is necessary to adopt corresponding measures in order to exhaust effectively.
Metal mold is non-yielding and easy to crack and deform during solidification.
