The invention discloses an ignition burner of a baking gun, which comprises an igniting needle, a spray rod body and a gas nozzle connected into a whole through washers, igniting needle fixing bolts and fixing nuts. The spray rod body is a communicating pipe body formed by a first joint, a second joint, a third joint, a fourth joint and a fifth joint through screwed connection in sequence, the gas nozzle is sleeved on the fifth joint and stretches into the cavity of the fourth joint, and the side wall of the cavity of the fourth joint is provided with at least one air inlet; a Karwar hole structure is arranged in the cavity of the third joint; and the end part of the second joint, which is far away from the gas nozzle, is provided with a partition board part, and a plurality of through holes are evenly distributed in the partition board part. The ignition burner of the baking gun is made by respective processing and screwed connection and is convenient for the local improvement of the burner structure; and by the design of the partition board part and the through holes, and the stability of ignition is effectively improved. Meanwhile, by adopting the mode of screwed connection, components of each burner and each joint have compact internal structure and reliable use as well as convenient and fast examination and maintenance.
Description
technical field [0001] The invention relates to a baking torch device for an industrial steelmaking furnace, in particular to a stable ignition ignition head used for a refining furnace toasting torch, and belongs to the technical field of smelting devices. Background technique [0002] The baking gun is a kind of baking gun used on the steelmaking furnace. It is an important mechanical equipment for the vacuum refining of molten steel (RH method). High to above 1450°C to reduce sticking to steel. [0003] The gun body of the baking gun can enter the vacuum tank through the gun hole on the hot elbow, spray air, oxygen, natural gas and other media into the vacuum tank, and ignite and heat the vacuum tank, so as to maintain the temperature of the refractory material in the tank, or After the refractory material is repaired, the refractory material is baked and heated to the required temperature. [0004] The ignition nozzle is an extremely important process part in the bakin...
