Severe magnesium leakage accident protection system for magnesium alloy melting furnace

Abstract

The invention discloses a severe magnesium leakage accident protection system for a magnesium alloy melting furnace. The protection system comprises a magnesium leakage detection device, a magnesium leakage collection system which can fully contain magnesium liquid in the melting furnace and is easy to be pulled out of the melting furnace and a gas protection system which can be timely started; the magnesium leakage collection system is a magnesium leakage disc which is provided with doubles layers of bottom plates, and the upper bottom plate is inclined; the gas protection system comprises avent pipe which delivers protective gas to the magnesium leakage disc, the vent pipe is arranged on the magnesium leakage disc and is installed on a furnace frame, and a first gas distributor which guarantees uniform gas distribution is arranged below the vent pipe and is communicated with the vent pipe through a vent hole; and the magnesium leakage detection device comprises a liquid level probeused for magnesium leakage detection, and the liquid level probe is vertically erected at the lower end of the upper bottom plate. The system has the beneficial effects that safety protection problemfor the severe leakage accident of the magnesium alloy melting furnace is solved; the leaked magnesium alloy can be recycled; and the installation and the debugging are flexible and convenient, and the system has easy maintenance.

Description

technical field [0001] The invention relates to a protection system for a malignant magnesium leakage accident of a magnesium alloy melting furnace. Background technique [0002] With the wide application of magnesium alloys in automobiles, 3C products, hardware and other industries, research on magnesium alloy smelting technology has also received increasing attention. Magnesium and its alloys are easily oxidized and burned in the melting process and release a large amount of heat energy. Once a malignant leakage accident occurs in the magnesium alloy melting furnace, it will definitely cause huge damage to the production environment and personnel. Therefore, it is of great significance to establish a protection mechanism for malignant leakage accidents of magnesium alloy melting furnaces. [0003] Magnesium leakage protection technology includes magnesium leakage detection and alarm technology, protection and recovery technology of magnesium liquid leakage. At present, t...

AI Technical Summary

Problems solved by technology

These processing methods have the following deficiencies: (1) Although the system cuts off the heating power supply of the melting furnace in time, the molten magnesium is difficult to solidify in a short time, so there may still be molten magnesium continuously from melting for a long time after the leakage of molten magnesium occurs. (2) The capacity of the leakage collector involved in the existing patent is limited, which requires the management personnel of the melting furnace to constantly replace the container, endangering the safety of the management personnel of the melting furnace, and there is a large potential safety hazard; (3) It is difficult to directly use the magnesium block recovered under the protection of other protection methods for reproduction, and there is a large waste; (4) in the process of flowing from the crucible for melting to the container for collecting the leakage, no protective measures are taken for the leakage, which is very easy to occur Rapid burning, endangering the safety of equipment and personnel
