The heating and heat preservation method comprises an aluminum alloy melt heating and heat preservation step, wherein in the step, an aluminum alloy melt heating and heat preservation device is used for carrying out heating and heat preservation on the melt; the aluminum alloy melt heating and heat preservation device comprises a furnace body, an electric heating element, a temperature controller and a temperature sensor; a containing cavity is formed in the furnace body; the containing cavity forms a melt temperature adjusting furnace chamber; the temperature sensor is mounted on the furnace body; the heating and heat preservation method is characterized in that the aluminum alloy melt heating and heat preservation step further comprises an indirect heating step; the indirect heating step comprises the step of forming a heating surface by utilizing an inner side face of a furnace lining of the furnace body; the heating surface is used for heating the aluminum alloy melt in the melt temperature adjusting furnace chamber. The heating and heat preservation method of the aluminum alloy melt, provided by the invention, has the advantages of simplicity and convenience for construction, uniform heating and uniform temperature distribution of a melting pool, easiness of mounting and replacing the electric heating element, convenience for cleaning molten slag of the melting pool and safety and reliability.

Description

technical field [0001] The invention belongs to the field of aluminum alloy smelting methods, in particular to an aluminum alloy melt heating and heat preservation method. Background technique [0002] Before the aluminum alloy is cast and formed, it is necessary to heat and melt the alloy charge to form an alloy melt. The obtained melt is purified and then transferred to a temperature-adjusted molten pool or a holding furnace. After adjusting the temperature to a temperature that meets the requirements of the subsequent casting process, Then use manual or pouring machinery to quantitatively supply the casting and forming equipment. In actual industrial production, in order to obtain a product with a stable configuration, it is necessary to strictly control the temperature of the poured aluminum alloy melt. In order to meet this requirement, in engineering, it is necessary to control the temperature of the aluminum alloy melt that meets the purity requirements in the heatin...
