Abstract
The utility model discloses a compound mouth of a river brick down, including the cylinder surface fabric brick that has the through -hole, the surface fabric brick outside is equipped with 7 font fixed blocks of round by section of thick bamboo brick cladding, section of thick bamboo brick top, and section of thick bamboo brick bottom is equipped with the one deck and strengthens the brick. The utility model discloses compare with the conventional art, design into whole brick the composite brick of four kinds of brick bluk recombinations, the cause has only the surface fabric brick in mouth of a river position real and the molten steel contact in the use down, fixed block and enhancement brick, the event is as long as these several positions use the refractoriness high, the flue is high in intensity, the high -grade material that the erosion -resisting characteristics is good, section of thick bamboo brick is because of the contactless molten steel, the temperature is lower, just play the effect of a base member, the lower low -grade refractory material of cost is adopted in the event, reduces production cost, and economic benefit can be improved as well.
Description
Technical field
This utility model belongs to fire resisting material field and in particular to a kind of compound lower nozzle brick.
Background technology
Steel mill needs for molten steel to be guided out converter after the completion of steel-making, and traditional steel-making fire door adopts refractory brick to lay
Become lower mouth of a river, lower nozzle brick needs with molten steel directly contact it is therefore desirable to select the high refractory brick of heat-resistance coefficient, therefore cost
Very high, and need to change after using certain number of times, and to a certain degree improve production cost.
Content of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of compound lower nozzle brick.
Technical scheme: in order to reach foregoing invention purpose, this utility model is specifically performed by: under one kind is compound
Nozzle brick, including the cylinder fabric brick with through hole, is coated by cylinder brick outside fabric brick, cylinder brick top is provided with a circle 7 font
Fixed block, cylinder brick bottom is provided with one layer of reinforcement brick.
Wherein, described fixed block, cylinder brick, reinforcement brick diameter successively decrease successively, form bucket shape.
Wherein, bondd by heat-resistant adhesive between described fabric brick, cylinder brick, fixed block and reinforcement brick.
Beneficial effect: this utility model, compared with conventional art, overall brick is designed to the composite brick that four kinds of brick body are combined,
Because of lower mouth of a river, real and steel contacts position only has fabric brick, fixed block and strengthens brick in use, as long as therefore this is several
Individual position uses the high-grade material that refractoriness is high, intensity is high, erosion-resisting characteristics is good, and cylinder brick is relatively low because not contacting molten steel, temperature,
Simply play the effect of a matrix, therefore lower-cost low-grade refractory material can be adopted completely, thus reduce producing into
This, increase economic efficiency.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
A kind of compound lower nozzle brick as shown in Figure 1, including the cylinder fabric brick 1 with through hole, outside fabric brick 1 by
Cylinder brick 2 coats, and cylinder brick 2 top is provided with a circle 7 font fixed block 3, and cylinder brick 2 bottom is provided with one layer of reinforcement brick 4, described fixed block 3,
Cylinder brick 2, reinforcement brick 4 diameter successively decrease successively, form bucket shape, by heat-resisting between fabric brick 1, cylinder brick 2, fixed block 3 and reinforcement brick 4
Binding agent bonds.
