[0002] Chinese patent ZL97238682.3 discloses an aspirating nozzle baking device, which is composed of an aspirating gun, a compressed air pipeline for combustion, and an aspirating roaster. The compressed air pipeline for combustion is connected to one end of the aspirating gun. When the combustion-supporting compressed air enters one end of the suction gun, the negative pressure generated at the other end continuously pushes the gas burned in the tundish into the suction end of the suction gun through the nozzle of the tundish, but the patent does not disclose the detailed parameters of baking. There is no specific description of the specific structure of the suction roaster, and there are uncertainties in the implementation effect of this patent

Embodiment Construction
[0009] see figure 1 , figure 2 :
[0010] A baking device for a submerged nozzle of a continuous casting tundish, comprising a toaster 4, a submerged nozzle 2, and an upper nozzle 1, the toaster 4 is cylindrical, and the submerged nozzle 2 extends into the inner cavity of the toaster 4 The telescopic sealing sleeve 3 is installed between the roaster 4 and the submerged nozzle 2, so that a sealed cavity is formed between the roaster 4 and the submerged nozzle 2. The outer wall of the roaster 4 is welded by steel plates, and the inner wall is lined with fire-resistant The top layer has a circular through hole, and the lower part of the hole is connected to the air pipe 6. The end of the air pipe 6 is equipped with a silencer 7. The drainage pipe 5 passes through the outer wall of the air pipe 6 and enters its inner cavity and is biased to the side of the silencer 7. It is telescopically sealed. Cover 3 is a hollow truncated cone, and its structure is: a cover is sewed into wi...

The invention relates to a roasting method and a roasting device for steel-making, especially for a continuous casting tundish immersion type water nozzle. The device comprises a roaster, an immersion type water nozzle, and an upper water nozzle, wherein the immersion type water nozzle is put into the roaster chamber, a retractable sealed cover is mounted between the roast and the immersion type water nozzle, a through-hole at the bottom of the roaster communicates with an external aeration pipe, a silencer is mounted on the end of the aeration pipe, and a drainage tube is taken into the aeration pipe inner chamber through the aeration pipe wall and leans to the side of the silencer. The device is used for roasting immersion type water nozzle with high quality, low cost, low noise, and energy-saving.
Description
1. Technical field [0001] The invention relates to a baking device and a baking method for steelmaking equipment, in particular to a baking device and a baking method for a submerged nozzle of a continuous casting tundish. 2. Background technology [0002] Chinese patent ZL97238682.3 discloses an aspirating nozzle baking device, which is composed of an aspirating gun, a compressed air pipeline for combustion, and an aspirating roaster. The compressed air pipeline for combustion is connected to one end of the aspirating gun. When the combustion-supporting compressed air enters one end of the suction gun, the negative pressure generated at the other end continuously pushes the gas burned in the tundish into the suction end of the suction gun through the nozzle of the tundish, but the patent does not disclose the detailed parameters of baking. The specific structure of the air-breathing roaster is also not specified, and there is uncertainty in the implementation effect of this...
