Abstract
A submersed water nozzle baking insulation device of an off-line tundish belongs to the technical field of steel-making auxiliary equipment and is used for quickly heating a submersed water nozzle of the off-line tundish. The technical scheme is that the submersed water nozzle baking insulation device comprises a roaster support, an insulation sleeve, a mixed gas tube, a nozzle, a high pressure air inlet tube and a gas inlet tube, the insulation sleeve is installed on the roaster support, the submersed water nozzle is placed in a cavity of the insulation sleeve, the nozzle is installed on a wall of the insulation sleeve, the high pressure air inlet tube and the gas inlet tube are connected with one end of the mixed gas tube, and the other end of the mixed gas tube is connected with the nozzle. The submersed water nozzle baking insulation device can quickly heat the submersed water nozzle, passes a 500-900 DEG C low strength area in a short time, guarantees using strength of the water nozzle, effectively keeps temperature of the submersed water nozzle, and prevents frequent breaking or perforating of the neck portion of the water nozzle caused by low temperature of the neck portion of the water nozzle. The submersed water nozzle baking insulation device prolongs service life of the water nozzle, reduces times for changing the water nozzle, and simultaneously saves energy and material cost.
Description
Technical field
The utility model relates to a kind of can making and wraps the device that submersed nozzle is rapidly heated in the off-line, belongs to steel-making auxiliary equipment technical field.
Background technology
Submersed nozzle must carry out abundant preheating before watering steel, utilizing the combustion gas baking mouth of a river of burning is the prewarming baking mode of commonly using.Under combustion-type prewarming baking mode, the mouth of a river is larger along the temperature rate of change of axis direction, and the temperature after the neck preheating of the mouth of a river is lower, is the main cause that causes the frequent fracture of mouth of a river neck and be prone to ring sample crackle.If therefore want to improve the preheat temperature of mouth of a river neck, must improve the prewarming baking mode at the mouth of a river.The cured effect of submersed nozzle directly affects service life at the mouth of a river, and the reduction in mouth of a river life-span must increase the number of times of nozzle quick-change, has so just increased the probability of production development accident.
Specifically, adopt roasting mode preheating submersed nozzle that following deficiency is arranged:
1, submersed nozzle heats up slowly.Because the aluminium carbon mouth of a river is that intensity is minimum at 500-900 ℃, if can not be rapidly heated, in this temperature range, toast the mouth of a river for a long time, will inevitably reduce the intensity at the mouth of a river, affect service life.So not only increased the loss of submersed nozzle, if the mouth of a river is not damaged and in time found, liquid level fluctuation of crystallizer increases, and can bring the mass defects such as crackle or slag inclusion to strand, the heat that partly bonds also is because mouth of a river damage causes, and can cause the bleed-out accident when serious.Simultaneously, the mouth of a river will be changed also it and can get rid of base after damaging, and causes waste.
2, frequent submersed nozzle, can increase the wearing and tearing to tundish upper nozzle, sometimes also large cut can occur, the slit between the upper and lower mouth of a river is increased, molten steel can be along slit flow out, cause slide mechanism folder steel, can't close blind plate, the improper accident of watering of stopping occurs, when serious, mouth of a river stopper is not closed completely, and also can cause larger security incident.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple and reasonable for structure, use safety, reliable, submersed nozzle is rapidly heated and the off-line that is incubated in bag submersed nozzle roasting attemperator.
The technical scheme that solves the problems of the technologies described above is:
Bag submersed nozzle roasting attemperator in a kind of off-line, it is comprised of roaster support, insulation sleeve, mixture pipe, burner, high pressure blast pipe, combustion gas blast pipe, the insulation sleeve is installed on the roaster support, submersed nozzle is placed in the inner chamber of insulation sleeve, burner is installed on the muff barrel, high pressure blast pipe and combustion gas blast pipe are connected to an end of mixture pipe, and the other end of mixture pipe is connected with burner.
Bag submersed nozzle roasting attemperator in the above-mentioned off-line, described insulation upper cartridge has mouth of a river carriage, and insulation sleeve door is arranged on the muff barrel.
Bag submersed nozzle roasting attemperator in the above-mentioned off-line, 4 universal wheels are arranged at the bottom of described baking support, and there is handrail the side of baking support.
The beneficial effects of the utility model are:
The utility model can be placed on submersed nozzle in the insulation sleeve and toast, and the insulation sleeve can make submersed nozzle be rapidly heated, and by 500-900 ℃ of low-intensity district, guarantees the working strength at the mouth of a river in the short time; The insulation sleeve can also avoid mouth of a river jugular temperature lower effectively to the submersed nozzle insulation, causes the phenomenon of the frequent fracture of mouth of a river neck or perforation.The utility model has improved the mouth of a river life-span, has reduced the number of times of changing the mouth of a river, and steady production is had very large benefit, has saved simultaneously the energy and the cost of anti-the material.
