Water gap baking equipment

Abstract

The invention discloses water gap baking equipment. The water gap baking equipment comprises a furnace body, and the furnace body is provided with a baking chamber for baking a water gap. A combustorfor providing fuel gas through a fuel gas supply pipeline assembly is arranged on the baking chamber, and a smoke exhaust pipe is arranged at the top of the baking chamber. The furnace body further comprises a combustion aiding air preheating chamber which is located at the top of the baking chamber and wrap the circumferential direction of the smoke exhaust pipe, and an air inlet and an air outlet are formed in the combustion aiding air preheating chamber. The air outlet communicates with the combustor, and the fuel gas supply pipeline assembly is connected with a gas pressurizing assembly for increasing the flowing speed of the fuel gas. According to the water gap baking equipment, combustion aiding air is preheated through smoke generated by fuel gas combustion, and meanwhile the flowing speed of the fuel gas is increased through the gas pressurizing assembly. More combustion aiding air can be driven to get into combustion, the combustion sufficiency is improved effectively, and thebaking temperature is improved; and the energy utilization rate is increased, it is ensured that the baking temperature of the water gap meets the needs, and the continuous casting quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of baking equipment, in particular to a nozzle baking equipment for continuous casting. Background technique [0002] In iron and steel production, the nozzle is located between the continuous casting tundish and the mold, and it is the guide pipe for molten steel to flow from the tundish to the mold. Its function is to prevent secondary oxidation of molten steel, control the flow state and injection speed of molten steel, and promote inclusions. Floating objects to prevent mold slag and non-metallic inclusions from being involved in molten steel, etc. The nozzle needs to be baked at a high temperature to prevent the molten steel from being blocked in the nozzle due to too low temperature or the stress concentration caused by the excessive temperature difference causing the nozzle to burst. Existing nozzle baking devices usually have electric baking and gas baking methods. In the gas baking method, the gas ...
