Abstract
A circulation pipe lining for a refining steel furnace belongs to the field of steel furnaces. The refining steel furnace containing the circulation pipe lining mainly comprises a dip pipe, a circulation pipe, a lower portion tank, a middle portion tank, an upper portion tank and a hot top cover. The circulation pipe comprises an ascending pipe and a falling pipe. When liquid steel is processed, under high-speed impact of rising liquid steel, a lap of annular bricks at an upper opening of the circulation pipe lining are prone to float up and down driven by friction of liquid steel flowing at high speed. Thus, gaps are formed between lining wearing-resistant materials, the liquid steel can leak into the gaps, and the circulation pipe and even the lower portion tank are damaged. One side of an upper ring brick of the circulation pipe is in a wedge shape, and the side is additionally provided with a D-shaped groove, thereby leading surrounding ramming materials to leak into the upper ring brick, additionally arranging a key seemingly, fixing the position of the upper ring brick and effectively resolving the problem that the upper ring brick is prone to float up.
Description
Technical field
A kind of circulating pipe liner of purified steel stove belongs to the converter field.
Background technology
External refining at present is widely used, and the purified steel stove mainly comprises dip pipe, circulating pipe, lower channel, intermediate channel, upper slot and hot top cover under this circulating pipe liner, and whole molten steel metallurgical reaction is in block has the vacuum tank of refractory lining, to carry out; When molten steel is handled; Under the high speed impact of rising molten steel, circulating pipe inner bushing ring brick is not easy to drive float downward in swiftly flowing molten steel friction before not transforming, and causes between the anti-material of liner the slit to occur; To such an extent as to molten steel penetrates, cause lower channel to be damaged.
The utility model content
The purpose of the utility model in order to solve the problem that above-mentioned prior art exists, provides a kind of circulating pipe liner of novel purified steel stove exactly.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of circulating pipe liner of purified steel stove is connected to each other and is formed by the ring brick, and said ring brick is wedge shape.
As preferably, said ring brick is provided with D type groove.
Utilize the converter of above-mentioned circulating pipe liner, be followed successively by dip pipe, circulating pipe, lower channel, intermediate channel, upper slot and hot top cover from top to bottom.
The utility model makes it compared with prior art owing to adopted above technical scheme, has the following advantages and characteristics:
1. through changing circulating pipe inner bushing ring brick into wedge shape, and increase D type groove,, increase frictional force, effectively stoped the last ring brick problem of come-up easily by the overall performance of ramming mass on every side.
2. make overall structure more reliable and more stable, improved service life greatly.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the utility model purified steel ring tube flowing structure sketch map;
Fig. 2 is the utility model circulation pipe ring brick structure sketch map.
The title of each label is following among the figure: 1-encircles brick, 2-indefinite form inserts, 3-heat-insulation layer, 4-box hat.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Embodiment one
The equipment that utilizes the utility model is a kind of steel secondary refining technological equipment that is used for production high-quality steel; Whole molten steel metallurgical reaction is in block has the vacuum tank of refractory lining, to carry out; This vacuum tank comprises dip pipe, circulating pipe, lower channel, intermediate channel, upper slot from top to bottom successively; Wherein dip pipe comprises a down-comer and a tedge, and circulating pipe also comprises a down-comer and a tedge.During steel-making, molten steel gets into lower channel through dip pipe tedge and circulating pipe tedge, flows into ladle through circulating pipe down-comer and dip pipe down-comer again from lower channel.
Before molten steel is handled, earlier dip pipe is immersed in the pending ladle molten steel, when vacuum tank vacuumized, the atmospheric pressure of molten steel surface forced molten steel to flow in the vacuum tank from dip pipe tedge and circulating pipe tedge.Because tedge constantly is blown into argon gas to molten steel, does not have the down-comer of Argon to produce a higher differential static pressure relatively, make molten steel flow to down-comer from the tedge entering and through the vacuum tank bottom, so constantly circulation is repeatedly.Under vacuum state; The gases such as argon gas in the vacuum tank molten steel, hydrogen, carbon monoxide of flowing through are taken away in the molten steel cyclic process, and simultaneously, the molten steel that gets in the vacuum tank also carries out a series of metallurgical reaction; Such as reaction between carbon and oxygen etc., so the circulating degasification refining is purified molten steel.
Molten steel is after rising to vacuum tank through the molten steel tedge in the process through down-comer; Because the high speed impact of molten steel; Circulating pipe inner bushing ring brick is not easy to drive float downward or sinking in swiftly flowing molten steel friction before transforming; Cause between the anti-material of liner the slit to occur,, cause circulating pipe to damage to such an extent as to molten steel penetrates.
Embodiment one
Circulating pipe comprises ring brick 1, indefinite form inserts 2, heat-insulation layer 3, box hat 4.
Circulation pipe ring brick 1 is transformed at present; Changing wedge shape into increases D type groove, and after ramming mass penetrated in the D type groove on every side, ramming mass was a kind of as amorphous refractory; The construction back is in aggregates; The influence of expanded by heating more can choke the ring brick, and this groove has been just as having increased key one, position that more can the retainer ring brick.Not only solved the ring brick problem of come-up easily through transforming ring brick brick shape, and made the circulating pipe structure more stable, the service life of having improved whole system greatly.
Embodiment two
Utilize the converter of circulating pipe liner, be followed successively by dip pipe, circulating pipe, lower channel, intermediate channel, upper slot and hot top cover from top to bottom.
What should explain at last is: the above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
