Problems solved by technology

[0003] Thermite reaction is extremely dangerous. Due to the low enthalpy of formation of alumina and the violent reaction, a large amount of high-temperature molten material is bound to be generated and splashes are easily formed, which may easily cause serious consequences such as burns to operators.

Embodiment Construction

[0020] Such as Figure 1 to Figure 4 Shown is an on-line ignition system for self-propagating reactions of titanium-aluminum alloys under supergravity, provided by the present invention, with safe and fast ignition operation and high ignition success rate. The ignition system includes an electric ignition head 1 and a power supply device 2 , and the ignition power of the electric ignition head 1 is provided by the power supply device 2 . The above is provided by setting an electric ignition head 1 and a set of power supply device 2 , and the ignition power of the electric ignition head 1 is provided through the power supply device 2 . In this way, when it is necessary to ignite the reaction raw materials in the titanium-aluminum alloy self-propagating reactor, it is only necessary to embed the electric ignition head 1 in the reaction raw materials first, and then provide the electric ignition head 1 with the power supply device 2. The ignition power supply causes the electric...

Description

technical field [0001] The invention relates to a high-gravity online ignition system, in particular to a high-gravity online ignition system for self-propagating reactions of titanium-aluminum alloys, and belongs to the technical field of design and manufacture of core components of metallurgical production equipment. Background technique [0002] Reduction of some metal oxides with aluminum can complete the oxide reduction reaction and obtain separated alloy and slag according to the released chemical reaction heat, without supplementing heat from the outside. Therefore, the thermite method is often used to smelt metals with high melting points, in which magnesium strips are used as ignition agents and potassium chlorate is used as a combustion aid. Magnesium bars can burn in air, and oxygen is the oxidant. But when part of the magnesium bars inserted in the mixture burns, potassium chlorate can be used as an oxidant to ensure the continuous burning of the magnesium bars,...
