High-stability aluminum alloy melting furnace for cold-chamber die-casting machine

Abstract

The invention discloses a high-stability aluminum alloy melting furnace for a cold-chamber die-casting machine, and belongs to the technical field of die-casting machine devices. The high-stability aluminum alloy melting furnace comprises a furnace body unit, a heating unit and a control unit. The high-stability aluminum alloy melting furnace is characterized in that the furnace body unit comprises a furnace wall, a reinforcing layer, an insulation layer and a bottom bracket, refractory bricks are stacked between the furnace wall and the reinforcing layer, high-temperature-resistant cement isused for caulking and fixing between every two adjacent refractory bricks, reinforcing rings are arranged in the reinforcing layer, the insulation layer is arranged inside the reinforcing layer, the bottom bracket is arranged in the insulation layer, and the insulation layer is annularly arranged on the side wall of the inner bottom of the insulation layer. According to the high-stability aluminumalloy melting furnace, the bottom bracket is additionally arranged inside the furnace body to make an inner tank more stable, and the bottom bracket cannot be damaged under the action of high temperature, so that bottom bracket bursting caused by high temperature is prevented. In addition, the insulation layer is more closely attached to the inner tank after the bottom bracket is utilized, and therefore the insulating effect is better.

Description

Technical field: [0001] This patent belongs to the technical field of die-casting machine equipment, in particular to a high-stability aluminum alloy melting furnace for cold-chamber die-casting machines. Background technique: [0002] The cold chamber die-casting machine refers to a die-casting machine in which the injection chamber and the injection punch are not immersed in the molten metal, but a certain amount of molten metal is poured into the injection chamber, and then injected. The injection method is placed vertically, which obviously follows the injection method of the hot die-casting machine. Before the die-casting machine die-casts, the aluminum metal needs to be melted. In the process of equipping the relevant melting furnace, the melting furnace is often not stable enough. Due to the short service life, melting furnaces are currently widely used thermal energy utilization equipment in industrial production. According to the type of heat source, melting furnac...

AI Technical Summary

Problems solved by technology

Generally, electric furnaces are composed of three major parts, namely, heating elements, furnace building materials and control devices. However, clay refractory bricks are used as furnace building materials for old-style melting furnaces. 35%-40% of the heat is lost through the furnace wall, and the overall thermal insulation performance is poor. Low thermal efficiency

[0003] It can be seen that the aluminum alloy melting furnace equipped in the above-mentioned existing die-casting machine obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
