Box Quenching Furnace Introduction and Process Flow

Box quenching furnaces, also known as hard mold forging or durable forging, involve pouring molten aluminum alloy into a metal mold to obtain castings. These furnaces often use metal cores, but can also employ sand cores or shell cores. Compared to pressure forging, the metal molds in aluminum alloy melting furnaces have a longer service life.

Forge Strengths

Advantages

Metal molds offer faster cooling rates, resulting in finer casting grain structure and enabling heat treatment for strengthening. The mechanical properties are up to 15% higher than those of sand mold forgings.

Box-type quenching furnace, castings have stable quality and superior surface roughness compared to sand mold forging, with a low rate of defective products.

Excellent working conditions, high productivity, and easy-to-learn for workers.

(2) Drawbacks

Metallic heat conductive coefficient is high, with poor filling capability.

Metallic bodies are non-permeable. It is necessary to adopt corresponding measures to effectively exhaust gases.

Metal is non-retractile and prone to cracking and deformation during solidification.
