Aluminum alloy casting furnace

Abstract

The invention relates to an aluminum alloy casting furnace which comprises a liquid transfer chute, a mechanical pump, a ceramic filtering plate, a refining degassing device, an aluminum alloy liquidlevel detection device, a furnace body, a top heating device or a bottom heating device, a feeding hole and a furnace door. When the furnace is used, an aluminum alloy liquid or a solid aluminum alloyis fed into the furnace body through the feeding hole after the furnace door is opened, and is heated to a certain process temperature through the top heating device or the bottom heating device; hydrogen is removed through the refining degassing device, impurities are removed through the ceramic filtering plate, the aluminum alloy liquid is lifted through the mechanical pump, and the lifted aluminum alloy liquid flows in the liquid transfer chute and then flows into a casting device; and quantification precision of the mechanical pump is dynamically compensated through a liquid level heightdetected by the aluminum alloy liquid level detection device. By adopting the aluminum alloy casting furnace, a high-quality melt can be provided for aluminum alloy casting, the mechanical pump is high in quantification precision after compensation, and compared with an aluminum alloy atmospheric pressure casting furnace, the aluminum alloy casting furnace does not need to be sealed and is small in furnace body manufacturing difficulty, low in cost and applicable to large-scale application.

Description

Technical field [0001] The invention relates to an aluminum alloy machine side furnace, which automatically provides quantitative and accurate high-quality aluminum alloy melt for the fields of aluminum alloy gravity casting, high-pressure casting, tilting casting and the like, and belongs to the field of aluminum alloy casting quantitative pouring. Background technique [0002] During the aluminum alloy casting process, a certain amount of aluminum alloy melt needs to be poured into a specific mold cavity. [0003] At present, in the field of quantitative aluminum alloy pouring, the low-end is mainly through setting up an aluminum alloy holding furnace next to the pouring unit, and manually operating a scoop to scoop a certain amount of aluminum alloy melt, and then manually transporting and pouring into the pouring system; currently on a large scale It is commonly used to use the manipulator to operate the scoop to scoop a certain amount of aluminum water from the aluminum alloy ...
