Abstract
The invention discloses a one with two argon-blowing gas supply method at converter bottom. The method is characterized by disconnecting at a proper position between a damaged argon tube and an air brick when one argon tube is blocked due to damaged deformation, and introducing argon from another argon tube to perform the one with two gas supply. The method is used for realizing one with two gas supply by connecting another argon tube after disconnecting at the proper position between the damaged tube and the air brick when one or two argon tubes are blocked due to damaged deformation caused by accident factors. The problem that the smelting operation of the converter is seriously influenced by the bad change of the argon-blowing flow field at the converter bottom caused by inoperation of the air brick is avoided.
Description
Technical field:
The present invention relates to the BOTTOM ARGON BLOWING air supply method of smelter top and bottom combined blown converter.
Background technology:
The steel-making converter major part of existing domestic smelter has all realized top bottom blowing, and at the symmetrical four blocks of gas permeable bricks of ladle bottom, a tunger tube of every gas permeable brick access, carries out BOTTOM ARGON BLOWING.Existing problems are, in converter smelting production process, because some unexpected factor can cause one or two impaired distortion obstructions of tunger tube, limitation because of arrangement space, generally can not repair or change, cause this gas permeable brick to quit work, and then cause the disadvantageous changes of bottom-blowing of converter argon flow field, have a strong impact on converter smelting operation, address this problem and become urgent need.
Patent content:
Overcome the deficiencies in the prior art, propose a kind of one-drawing-two type bottom-blowing of converter argon air supply method that makes gas permeable brick non-stop run.One-drawing-two type bottom-blowing of converter argon air supply method is that the correct position between impaired tunger tube and gas permeable brick disconnects, by another root tunger tube, accesses argon gas, carries out one-drawing-two type air feed when the impaired distortion of certain root tunger tube is stopped up.Adopt method of the present invention correct position between impaired tunger tube and gas permeable brick when some unexpected factor causes one or the impaired distortion of two tunger tubes to stop up to disconnect, be connected with another root tunger tube, realize one-drawing-two type air feed.Avoided gas permeable brick to quit work and caused the disadvantageous changes of bottom-blowing of converter argon flow field, having had a strong impact on the problem of converter smelting operation.
Accompanying drawing explanation:
Fig. 1 is Argon air supply method view of the present invention.
Embodiment:
When the impaired distortion of certain root tunger tube 1 is stopped up, the correct position between impaired tunger tube and gas permeable brick 2 disconnects, and is connected with another root tunger tube, realizes one-drawing-two type air feed.
Claims (1)
1. an one-drawing-two type bottom-blowing of converter argon air supply method, is characterized in that: when the impaired distortion of certain root tunger tube is stopped up, the correct position between impaired tunger tube and gas permeable brick disconnects, by another root tunger tube, accesses argon gas, carries out one-drawing-two type air feed.
