Pressure-flow-type magnesium alloy smelting heat insulating furnace

Abstract

The invention relates to a pressure-flow-type magnesium alloy smelting heat insulating furnace which comprises a furnace body provided with a heat insulating layer, a crucible arranged inside a hearth, a heating element, a temperature measuring device and a furnace cover, wherein the furnace body comprises a furnace shell and a furnace liner; a water-cooling flange is arranged at a position where the upper part of the furnace body is matched with the furnace cover, and internally provided with high temperature resistant and fire-resistant filler material and a silicon rubber sealing ring; the water-cooling flange is internally filled with circulating cooling water; the furnace cover is locked with the furnace body by a compressing mechanism; a temperature thermocouple and a protection gas input pipeline extend into the furnace through inserting holes of the furnace cover, a pressure release pipe is arranged on the furnace cover, and the top of the pressure release pipe is provided with a safety valve and an exhaust valve; and a transfer pipette is introduced into the hearth through the furnace body. The furnace integrates the functions of smelting, heat insulating and melt transmission, accurately controls the flow rate of magnesium alloy melt, extracts the purer magnesium alloy melt at the middle part of the crucible, realizes continuous transmission with fixed flow rate, and prevents oxidation and combustion of the magnesium alloy. Furthermore, by combining corresponding foundry equipment, the magnesium alloy product with high quality can be prepared, and the equipment can be safe in use as well as simple and convenient for operation.

Description

technical field [0001] The invention relates to a magnesium alloy smelting equipment, in particular to a pressure-flow type magnesium alloy smelting and holding furnace, which belongs to the technical field of nonferrous metals. Background technique [0002] Magnesium alloys have many advantages and are known as "green engineering materials in the 21st century". In recent years, the research and application of magnesium alloys have attracted increasing attention from the material science and industry circles. With the reduction of costs and the breakthrough of technical bottlenecks, magnesium and magnesium alloys have become an increasingly strong demand for magnesium alloy thin plates and strips in industries such as automobiles, electronics, and communications. Magnesium alloy casting and rolling technology has the advantages of short process, low cost and high efficiency, and is the main development direction of magnesium alloy strip processing technology.

Problems solved by technology

Due to the low density of the magnesium alloy melt and the small density difference with the inclusions, the inclusions in the magnesium alloy melt will slowly float or sink to the top or bottom of the crucible, and the transition is made by tilting machinery or liquid level difference launders When the melt is conveyed in other ways, the upper scum and bottom scum cannot be effectively removed

Mechanical pump is also a device widely used in foundry enterprises at present, but the preheating and post-cleaning of the device need to be completed in the configured flux furnace, which increases equipment investment; in addition, the delivery flow of metal pump is relatively large, and it is easy to block
