Embodiment Construction

[0018] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0019] See figure 1 , is a structural schematic diagram of the implementation state of a baking device for a molten steel tank according to the present invention, including a molten steel tank 1, a baking cover 2 and two burner nozzles 3, the baking cover 2 is provided with an air extraction pipe 4, and one end of the air extraction pipe 4 A metal mesh 5 is provided with a mesh size of 2-3mm. The metal mesh plays a protective role to prevent clogging of inhaled residue during work. The other end of the exhaust pipe 4 is connected to the vacuum pump 6, and the diameter of the exhaust pipe 4 is 40-50mm. The air extraction pipe 4 is wound on the reel of the electric take-up device 7 . One end of the air extraction pipe 4 is provided with a counterweight 8, so that the air extraction pipe 4 can be lifted and lowered reliably under the action of the e...

Abstract

The invention relates to the field of ladle baking, in particular to a baking method and a device of a ladle. The baking device comprises a baking cover and a burner nozzle; an exhaust pipe is arranged on the baking cover; a metal mesh is arranged at one end of the exhaust pipe and has a mesh size of 2-3 mm; the other end of the exhaust pipe is connected with a vacuum pump; and the exhaust pipe has a diameter of 40-50 mm. A counter weight is arranged at one end of the exhaust pipe. The exhaust pipe is wound on an electric winding device. Compared with the prior art, the baking method and the device of the ladle have the beneficial effects that 1), the bottom of the ladle is exhausted, so that the thermal circulation from top to bottom is formed in the ladle to eliminate baking dead angles in the ladle and keeping uniform baking effect in the ladle; 2), flames are prevented from upward channeling in the baking process to reduce the heat loss and improve the thermal efficiency; and 3), the temperature loss in the baking process is reduced to promote stable production.

Description

technical field [0001] The invention relates to the field of baking molten steel tanks, in particular to a method and device for baking molten steel tanks. Background technique [0002] The baking effect of the molten steel tank directly affects the temperature drop of the steel tapping and the system temperature in the whole production process. The use of over-point tanks, overhaul and minor repair tanks in daily production often causes production fluctuations. At present, the baking of molten steel tanks adopts top-spray baking, and the baking effect is not ideal during baking, and the baking temperature of the tank body is uneven, especially the bottom part of the tank body has a phenomenon of baking dead angle, and the baking is not in place. The temperature difference between the upper part and the bottom of the tank body is measured to be more than 400°C, and the flames rise up during baking, resulting in low thermal efficiency, resulting in a large loss of energy cons...
