TECHNICAL FIELD
[0001] The utility model relates to the technical field of aluminothermy, more particularly to an electric start type aluminothermic agent ignition device. BACKGROUND
[0002] Aluminothermy is a chemical reaction based on the high reducing property of aluminum under high temperature conditions. In this reaction, metallic aluminum as a reducing agent is mixed with metal oxides (such as iron oxides, copper oxides, etc.), and a violent exothermic reaction is initiated by ignition, generating elemental metals and aluminum oxide. This process releases a large amount of heat, with temperatures reaching above 2500°C, so aluminothermy 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 in the military and special applications as a heat source or explosive.
[0003] The characteristics of aluminothermy are fast reaction speed, large heat release, and simple operation, but due to the violent nature of the reaction, there are high requirements for the ignition method and safety measures.
[0004] The existing ignition methods for aluminothermic agents include: (1) using magnesium strips as fuses to ignite the aluminothermic agent using the high temperature generated by the combustion of magnesium strips. To improve the combustion efficiency of magnesium strips, potassium chlorate, potassium permanganate, potassium nitrate, barium peroxide, etc. are usually mixed in. However, these oxidizing agents may produce toxic smoke during combustion, 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 it comes into contact with the aluminothermic agent, thereby igniting the aluminothermic agent. This method has a slow heat release rate, which may lead to incomplete or failed aluminothermic reactions; (3) directly using a flame gun to heat the aluminothermic agent to achieve ignition. This method is simple to operate, but requires precise control of the temperature and heating time of the flame, otherwise it may cause unstable ignition and even safety accidents. These methods have problems such as unstable ignition, complex operation, safety hazards, poor environmental performance, etc. in actual application.
[0005] Therefore, it is necessary to solve the above technical problems. SUMMARY
