Abstract
The utility model belongs to the technical field of refractory brick tools, and particularly relates to a furnace door brick for a steel tapping mouth. The furnace door brick for the steel tapping mouth comprises a refractory castable pre-cast block, a water outlet groove is formed in the inner side of the upper end of the refractory castable pre-cast block, a groove type magnesia carbon brick is arranged inside the water outlet groove, and a magnesia carbon security brick is arranged between the groove type magnesia carbon brick and the refractory castable pre-cast block. An arc-shaped deformed steel bar and two straight deformed steel bars are arranged in the refractory castable pre-cast block, the arc-shaped deformed steel bar and the water outlet groove are identical in radian, and the two straight deformed steel bars are symmetrically arranged on the two sides of the arc-shaped deformed steel bar and make contact with the arc-shaped deformed steel bar. The furnace door brick for the steel tapping mouth successfully solves the problem of the service life of domestic steel tapping mouths, lowers the cost, and has great significance in safe operation and use.
Description
Technical field
The utility model belongs to refractory brick apparatus technical field, relates in particular to a kind of tapping mouth furnace door brick.
Background technology
Domestic AOD stove is smelted while producing, and after the discontinuity that its traditional resistance to material in tapping position (tapping mouth) is subject to molten steel is washed away, severe attrition, causes smelting work to be affected, and for guaranteeing to produce, often will carry out continuous a large amount of repairing, even blowing out overhaul.At present for improving the service life of AOD stove tapping mouth, mostly adopt various high-grade castable refractory rammings, cast and integral prefabricated three kinds of forms, but totally it seems that to have cost performance not high, the situations such as the life-span is undesirable, this product is intended to use machine compression set type refractory product to match in conjunction with pre-formed two kinds of techniques, addresses the above problem.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of tapping mouth furnace door brick is provided, and its technical scheme is as follows:
A kind of tapping mouth furnace door brick, its feature in, described tapping mouth comprises castable refractory prefabricated section with furnace door brick, the inner side, upper end of described castable refractory prefabricated section offers effluent trough, in described effluent trough, be provided with slot type magnesia carbon brick, between described slot type magnesia carbon brick and castable refractory prefabricated section, be provided with magnesium carbonaceous insurance brick, in described castable refractory prefabricated section, be provided with arc screw-thread steel and two straight shape screw-thread steels, described arc screw-thread steel is consistent with the radian of effluent trough, two described straight shape screw-thread steels are symmetrically distributed in the both sides of arc screw-thread steel, two described straight shape screw-thread steels contact with arc screw-thread steel.
Optimal way is, described slot type magnesia carbon brick and magnesium carbonaceous insurance brick with fireproof prefabricated Product Process in advance on castable refractory prefabricated section.
The tapping mouth furnace door brick that the utility model provides, manufacture production technology and feature own due to magnesia carbon brick, determine that it is aspect high temperature, high-strength, thermal shock, quality stability, more much higher than unsetting product, this just determines product comprehensive refractory casting product that surpasses in service life when tapping.
The utility model is owing to taking slot type design, and during tapping, molten steel, all by flowing out in effluent trough, avoids impacting other refractory part of both sides moulding by casting, causes both sides castable refractory damage.
Castable refractory prefabricated section in the whole product of the utility model mainly plays the effect of support structure, does not re-use more expensive raw material manufacture, and cost reduces greatly.
The utility model was washed thin during without brick when using later stage slot type magnesia carbon brick bottom, the insurance brick that thickness is relatively thin can continue to use a period of time, now stokehold steel worker can find this situation by range estimation, and this design can, to providing significant warning service life, be beneficial to safety in production.
In castable refractory prefabricated section described in the utility model, be provided with arc screw-thread steel and two straight shape screw-thread steels, play integrated connection reinforcement effect, prevent from not producing at that time infringement owing to transporting and lifting.
Its manufacturing technique method is:
While 1, utilizing machine to press refractory product to produce, more easily reach high-strength, fine and close, stay-in-grade feature, produce slot type magnesia carbon brick and magnesium carbonaceous insurance brick that resistance to molten steel washes away.
2, use castable refractory is by two kinds of magnesia carbon bricks in advance built in fixed position, and Prefabrication technique is carried out according to fireproof prefabricated Product Process.
The utility model has successfully solved domestic tapping mouth problem in service life, has reduced cost simultaneously, and this design has the use of safety operation widely meaning in addition.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
A kind of tapping mouth furnace door brick, its feature in, described tapping mouth comprises castable refractory prefabricated section 1 with furnace door brick, the inner side, upper end of described castable refractory prefabricated section 1 offers effluent trough 2, in described effluent trough 2, be provided with slot type magnesia carbon brick 3, between described slot type magnesia carbon brick 3 and castable refractory prefabricated section 1, be provided with magnesium carbonaceous insurance brick 4, in described castable refractory prefabricated section 1, be provided with arc screw-thread steel 5 and two straight shape screw-thread steels 6, described arc screw-thread steel 5 is consistent with the radian of effluent trough 2, two described straight shape screw-thread steels 6 are symmetrically distributed in the both sides of arc screw-thread steel 5, two described straight shape screw-thread steels 6 contact with arc screw-thread steel 5.
Optimal way is, described slot type magnesia carbon brick and magnesium carbonaceous insurance brick with fireproof prefabricated Product Process in advance on castable refractory prefabricated section.
The tapping mouth furnace door brick that the utility model provides, manufacture production technology and feature own due to magnesia carbon brick, determine that it is aspect high temperature, high-strength, thermal shock, quality stability, more much higher than unsetting product, this just determines product comprehensive refractory casting product that surpasses in service life when tapping.
