Description

A kind of special shaped brick and bridge structure for being used to build furnace cupola gap bridge by laying bricks or stones

Technical field

A kind of special shaped brick and bridge structure for being used to build furnace cupola by laying bricks or stones is the utility model is related to, belongs to casting processing auxiliary and sets Standby technical field, more particularly to a kind of special shaped brick and bridge structure for being used to build furnace cupola gap bridge by laying bricks or stones.

Background technology

Furnace cupola, it is the visual plant of melting iron in Foundry Production, sand mold is poured into after casting pig is fused into molten iron In after cooling unpack and obtain casting.Furnace cupola is a kind of vertical cylindrical shape smelting furnace, is divided into forehearth and rear stove, and forehearth divides again For tapping hole, slag notch, bell, preceding cupola well and gap bridge, rear stove is divided into three parts again, respectively pushes up stove, waist stove and cupola well, waist Stove separates with bustle pipe, repaiies stove and closes afterwards, is sealed with mud, and it is heat exchanger to push up on stove.Furnace cupola is mainly used in cast iron Part produces, and also to coordinate pneumatic steelmaking, because of furnace roof opening upwards, therefore claims furnace cupola.

At present, can smoothly be used in cupola melting molten iron in order to ensure passing a bridge, foundry is when repairing gap bridge Must arrange brickwork industrial grade highest master worker to work and from top-quality refractory material to complete this.It is actual raw Because gap bridge will bear 1550 DEG C or so of the thermal stress effect for crossing heating molten steel and clinker in production, high temperature will be born by further passing a bridge The physical impact and chemical reaction of molten iron and clinker act on, and further to bear hot wind action.Pass a bridge in so severe work Make the accident often metal run out under environment.Once gap bridge is metal run out, substantially melt the work of molten iron and will stop Only.Even if maintaining fusing molten iron reluctantly, the quality of its molten iron will deteriorate, while the labor intensity of smelter is multiplied, and enters one The risk for walking employee's scald is increased sharply.

Utility model content

It is used to build in view of the above-mentioned drawbacks of the prior art, the technical problems to be solved in the utility model is to provide one kind The special shaped brick of furnace cupola gap bridge and the leakproof bridge structure with the special-shaped brick masonry are built, it can not only solve to prevent molten iron from mistake Bridge is revealed, while can reduce the industrial grade requirement for brickwork work.

In order to solve the above technical problems, the utility model employs such a abnormity for being used to build furnace cupola gap bridge by laying bricks or stones Brick, it is made up of upper brick body and lower brick body；Molten iron, which is provided with, on one side end face of lower brick body crosses groove and guide groove；Cloth in upper brick body The guiding projection being installed in guide groove can be coordinated by being equipped with.

In a kind of preferred embodiment of the present utility model, molten iron crosses groove and guide groove is arranged parallel to.

In a kind of preferred embodiment of the present utility model, guide groove includes multiple；Multiple guide grooves are symmetrically arranged in Molten iron crosses the both sides of groove.

In a kind of preferred embodiment of the present utility model, upper brick body is provided with a side end face and the molten iron of guiding projection Cross groove and surround a water passage for the outflow of forehearth molten iron.

In a kind of preferred embodiment of the present utility model, the width of guiding projection is equal to the width of guide groove；It is oriented to Height of the projection along its protrusion direction is more than or equal to the depth of guide groove.

In a kind of preferred embodiment of the present utility model, upper brick body and lower brick body are rectangular-shape.

The invention also discloses a kind of bridge structure, it includes special shaped brick；The both sides of special shaped brick and bottom bag are attached There is high-temperature flame-proof cotton；Heavy refractory brick has been pressed at the top of special shaped brick.

In a kind of preferred embodiment of the present utility model, on the upper surface of the high-temperature flame-proof cotton of special shaped brick bottom Uniformly it is coated with fire clay.

In a kind of preferred embodiment of the present utility model, heavy refractory brick thickness is 115mm.

The beneficial effects of the utility model are：The utility model is simple in construction, casting is easy to use, due to will be originally with three The gap bridge that more than ten pieces of standard refractories turn to build by laying bricks or stones is integrated into two pieces of special-shaped brick masonries, reduces the skill built by laying bricks or stones and passed a bridge for brickwork work Art class requirement, prevent to metal run out because passing a bridge；It is used that the utility model by using two blocks of special shaped bricks pieces together furnace cupola Bridge structure, caused gap when effectively reducing polylith laying fireproof bricks furnace cupola in the prior art, meanwhile, by different Set on shape brick molten iron cross groove facilitate molten iron by, avoid the leakage of molten iron, while set by being crossed in molten iron by groove Guide groove and guiding projection are put, facilitates closing up for brick body and lower brick body, while ensure that both compactness so as to more It efficiently avoid the leakage of molten iron；Passed a bridge by using special-shaped brick masonry of the present utility model, will can originally need 30 The gap bridge of several pieces of laying fireproof bricks is integrated into two blocks of special form bricks come the special gap bridge built by laying bricks or stones, significantly reduces workmen's Labor intensity, reduce gap bridge and build man-hour by laying bricks or stones.

Brief description of the drawings

Fig. 1 is a kind of structural representation for being used to build the special shaped brick of furnace cupola gap bridge by laying bricks or stones of the utility model embodiment；
