The invention discloses cast aluminum nitrogen heating equipment and method capable of achieving balanced heating, and relates to the technical field of cast aluminum, the cast aluminum nitrogen heating equipment comprises a heating box, cover plates are arranged on the front side wall and the rear side wall of the heating box, and balanced heating assemblies are arranged in the cover plates; the air inlet and the air outlet in the top of the heating box are fixedly connected with straight cylinders; the top of the straight cylinder is respectively connected with a gas inlet shunting box and a gas outlet shunting box, the outer end of the gas inlet shunting box is fixedly connected with a nitrogen inlet pipe, and the outer end of the gas outlet shunting box is fixedly connected with a nitrogen outlet pipe; the top of the heating box is connected with a circulation assembly which is connected with the air inlet flow dividing box and the air outlet flow dividing box. The top of the heating box is further connected with a flow dividing assembly, when the flow dividing assembly is opened, nitrogen in the nitrogen inlet pipe passes through the heating box and then is exhausted through the nitrogen outlet pipe, and when the flow dividing assembly is closed, nitrogen in the heating box passes through the air outlet flow dividing box, the circulating assembly and the air inlet flow dividing box and then enters the heating box. By means of the mode, balanced heating of aluminum casting nitrogen is achieved, dead angles are avoided, and the phenomenon of unbalanced heating is avoided.
Description
technical field [0001] The invention relates to the technical field of cast aluminum, in particular to a nitrogen heating device and method for uniform heating of cast aluminum. Background technique [0002] At present, there are many kinds of die-casting aluminum alloys, which are widely used in 3C, automobile and other fields because of their characteristics of small specific gravity, good heat transfer, good electrical conductivity, environmental protection, and recyclability. [0003] In order to ensure the quality of the cast aluminum alloy, it needs to be protected with nitrogen. When nitrogen is used, a heater is required to heat it. The existing heater can only heat in one direction, and there are a lot of heating dead corners. equilibrium phenomenon. [0004] Therefore, a nitrogen heating equipment and method for uniform heating of cast aluminum are proposed to solve the above problems. SUMMARY OF THE INVENTION [0005] The purpose of the present invention is to...
