Description

Technical Field

[0001] The present invention relates to the technical field of thermite welding, and more specifically, to an electrically started thermite ignition device and a use method thereof. Background Art

[0002] Thermite reaction is a chemical reaction that takes place under high temperature conditions based on the high reducibility of aluminum. In this reaction, aluminum metal is mixed with metal oxides (such as iron oxides, copper oxides, etc.) as a reducing agent, and a violent exothermic reaction is triggered by ignition to generate metal elements and aluminum oxide. This process releases a large amount of heat, and the temperature can reach over 2500°C. Therefore, thermite reaction is used in the metallurgical industry to refine high-melting-point metals, in the fields of railways, ships, aerospace, etc. for metal welding and cutting, and as a heat source or explosive in military and special purposes.

[0003] The characteristics of thermite reaction are fast reaction speed, large heat release and simple operation, but due to its violent reaction, it has high requirements on ignition method and safety measures.

[0004] Existing methods for igniting thermite include: (1) using magnesium bars as fuses and utilizing the high temperature generated by the burning of magnesium bars to ignite thermite. In order to improve the combustion efficiency of magnesium bars, oxidants such as potassium chlorate, potassium permanganate, potassium nitrate, and barium peroxide are usually mixed in. However, these oxidants may produce toxic smoke during the combustion process, posing a threat to the environment and the health of operators; (2) using a mixture of potassium permanganate and glycerol or glucose as an initiator, which will undergo a slow exothermic reaction when in contact with thermite, thereby igniting thermite. This method has a slow heat release rate and may result in incomplete or failed thermite reaction; (3) directly using a flame gun to heat thermite to achieve the purpose of ignition. This method is simple to operate, but requires precise control of the flame temperature and heating time, otherwise it is easy to cause unstable ignition and even cause safety accidents. These methods have problems such as unstable ignition, complex operation, safety hazards, and poor environmental protection in actual applications.

[0005] Therefore, it is necessary to solve the above technical problems. Summary of the invention
