Quantitative taking furnace for molten metal in melting furnace

Abstract

The invention relates to the field of melting furnaces, in particular to a quantitative taking furnace for molten metal in a melting furnace. According to the quantitative taking furnace for molten metal in the melting furnace, molten metal in the quantitative furnace can be directly introduced into a feed inlet of a die-casting machine, quantitative storage of the molten metal can be realized, atraditional die-casting ladling machine and heat preserving furnace are replaced, the cost is greatly saved, and the energy consumption is greatly reduced. A user can adjust the position of a quantitative plunger, so that the volume in a quantitative cavity is changed, and different volumes of quantitative supply is realized; besides, a first heating pipe and a second heating pipe are arranged ina furnace body and can be used for heating and heat preservation of the whole furnace body, heat loss of the molten metal is reduced, furthermore, the furnace body is further connected with a connecting pipeline used for injecting protective gas, positive pressure slightly higher than atmospheric pressure is supplied, the molten metal is isolated from oxygen all the time, the oxidation consumptionof the molten metal is reduced, and the quality of the molten metal is also improved.

Description

technical field [0001] The invention relates to the field of melting furnaces, in particular to a melting furnace metal liquid quantitative feeding furnace. Background technique [0002] In the field of metallurgy, melting metal is a very common and important process. The molten metal can be used to cast metal parts of various shapes. The melting furnace is a new type of high-efficiency and energy-saving aluminum melting furnace developed according to the aluminum smelting process. It is mainly used for melting and heat preservation of aluminum ingots, and it can well meet the aluminum smelting process. The furnace is composed of melting furnace, crucible, heating element, furnace cover lifting mechanism, electrical automatic temperature control system and so on. The furnace shell is welded into a cylindrical shape by section steel and steel plate. [0003] At present, in the rapid development of the domestic automobile industry, communication industry, construction indus...

AI Technical Summary

Problems solved by technology

[0004] In the process of transferring molten metal, it is necessary to keep the molten metal in the holding furnace for heat preservation, and use a die-casting soup dispenser to pour the molten metal from the dosing furnace through the holding furnace into the corresponding die-casting machine, which consumes a lot of energy and costs High, not conducive to environmental protection
