Multi-working-condition metal liquid drop ignition experiment device

Abstract

The invention discloses a metal liquid drop ignition experiment device under multiple working conditions. The device comprises a high-pressure cabin, a high-frequency electromagnetic heating furnace, a sample filling assembly and a bottom plate heating and heat preservation assembly, a high-pressure cabin is defined in the high-pressure cabin, and the high-pressure cabin is provided with a gas inlet hole for injecting gas into the high-pressure cabin; the high-frequency electromagnetic heating furnace is installed on the side wall of the high-pressure cabin and comprises an electromagnetic suspension heating furnace coil located on the upper portion of the high-pressure cabin; the sample filling assembly comprises a linear motion module, and one end of the linear motion module is used for containing a metal particle sample fed from the first operation hole; and the bottom plate heating and heat preservation assembly can be horizontally and rotatably arranged in the heat preservation box and is used for placing a to-be-ignited test piece fed from the second operation hole and heating the to-be-ignited test piece according to experiment requirements. According to the invention, different types of molten metals can be simulated to ignite combustible materials under different working conditions.

Description

technical field [0001] The invention relates to the technical field of metal droplet ignition experimental devices, in particular to a metal droplet ignition experimental device with multiple working conditions. Background technique [0002] The problem of fires caused by hot particles has grown in recent years. In daily life, exposed high-voltage wires collide with each other under the action of strong winds, cutting machines and welding machines are working, fireworks explode at a short distance from buildings, and the high-temperature particles produced by them may ignite combustible materials. Thus causing a fire. In the field of aircraft, high-temperature molten metal is the main cause of the spread and expansion of fire in the fuselage or engine. [0003] Scholars have been devoting themselves to the research of the above-mentioned high-temperature particle ignition process. Some scholars have studied the physical characteristics of arc discharge process, metal cutt...

Problems solved by technology

However, due to the difficulty in controlling the quality, temperature, and speed of the melt during the ignition process of the high-temperature metal melt, there is no experimental study on the ignition process of the high-temperature metal melt.
