Continuous casting tundish moulding bed combustor

Abstract

The invention discloses a continuous casting tundish moulding bed combustor which comprises a combustion chamber and an external heat transferring chamber, wherein the combustion chamber is cylindrical, and a sealed flange plate is arranged at the top of the combustion chamber; an air injection hole is formed in the center of the flange plate; the bottom of the combustion chamber cylinder is a non-sealed structure; the external heat transferring chamber takes the shape of a hollow cylinder; and a heating pipe is arranged at the bottom of the external heat transferring chamber. When the continuous casting tundish moulding bed combustor is mounted, the combustion chamber is arranged in the external heat transferring chamber in a sleeving manner; the continuous casting tundish moulding bed combustor can overcome the defects in the prior art that heating is not uniform and heat transferring is difficult; the entire moulding bed is heated in a more uniform and reliable manner; and the continuous casting tundish moulding bed combustor is small in deformation, long in service life, safe to operate, high in production efficiency and remarkably reduced in production cost and is widely applicable to matched application for forming of continuous casting tundish.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a continuous casting tundish tire mold burner. Background technique [0002] In the molding operation of the continuous casting tundish, the tire mold needs to be heated to form the overall heat insulation layer of the tundish. At present, there are two commonly used heating forms: one structure is to set the burner above the tire mold, The heat is transferred to the bottom and surroundings of the tundish tire mold through the combustion channel or the fire box; another structural form is to directly extend the gas pipeline and the burner into the inside of the tundish tire mold to heat the bottom and surroundings of the tundish tire mold ; These two structural forms all have the following problems: ①The temperature in the bottom area of ​​the package facing the combustion channel or the fire box is high, while the temperature of the package wall in the length direction is insuff...

[0002] In the molding operation of the continuous casting tundish, the tire mold needs to be heated to form the overall heat insulation layer of the tundish. Currently, there are two commonly used heating forms: one structure is to set the burner above the tire mold, The heat is transferred to the bottom and surroundings of the tundish tire mold through the combustion channel or the fire box; another structural form is to directly extend the gas pipeline and the burner into the inside of the tundish tire mold to heat the bottom and surroundings of the tundish tire mold ; These two structural forms all have the following problems: ①The temperature in the bottom area of ​​the package facing the combustion channel or the fire box is high, while the temperature of the package wall in the length direction is insufficient; ②Because the burner is generally located above the tire mold, the tire The temperature in the upper area of ​​the mold is too high, and it is difficult to transfer heat to the bottom of the tire mold. Due to uneven heating, the baking efficiency of the tundish insulation layer is not good; ③ due to uneven heating of the bottom and surrounding of the tire mold, resulting in The tire mold is easily deformed and the service life is reduced
