Embodiment Construction

[0034] The large-scale continuous smelting system with an annual production capacity of 10,000 tons of magnesium alloy liquid is calculated as 60% of the annual smelting time utilization rate, and the smelting rate is 2 tons per hour. Design a large continuous melting system based on 2 tons per hour.

[0035] Since the magnesium alloy is heated at 480°C for a long time in the atmosphere, the oxidation is not obvious, and the temperature is even allowed to be higher during rapid heating. The preheating furnace needs to rapidly and uniformly heat 2 tons of magnesium alloy ingots from room temperature to close to 500°C. At the same time, the temperature must be uniform inside and outside. When the frequency of induction heating is low, the skin effect is low and the thermal conductivity of magnesium is good. Frequency induction heating. Calculated from the heat capacity of magnesium. Considering factors such as theoretical output power and thermal efficiency, the output power o...

Abstract

The invention belongs to a magnesium alloy melting device, in particular to a large-sized continuous melting system for magnesium alloy, which is used for meeting a large number of requirements of continuous casting-rolling, continuous casting, casting and other production on magnesium alloy liquid. The system separates a solid preheating stage from a liquid high-temperature stage, wherein solid preheating is rapidly performed under simple atmospheric conditions by use of induction heating, and the high-temperature stage is divided according to different links of melting, refining and precipitation-purification, so as to strengthen single functional links. Therefore, the system has the advantages of improving working conditions, ensuring continuous production process, reducing production expenses and improving metallurgical quality.

Description

technical field [0001] The invention relates to a magnesium alloy smelting equipment, in particular to a large-scale continuous smelting system for providing magnesium alloy liquid. Background of the invention [0002] At present, magnesium alloy smelting equipment includes pit furnaces, double furnaces, triple furnaces, group furnaces, reverberatory furnaces and multi-chamber furnaces. The advantage of the pit furnace is that it has strong production flexibility and can produce magnesium alloy liquid with accurate control of various components and high quality. There are many disadvantages of pit furnaces, such as harsh production conditions, high labor intensity, strong influence of human factors on quality, poor product quality stability, and high heat energy consumption. The double furnace uses a siphon to comprehend two crucible furnaces to form a system. One furnace is responsible for melting and alloying, and the other furnace is responsible for temperature adjustmen...
