Description

The refractory brick of stabilization pouring pressure

Technical field

The utility model belongs to metal casting and manufactures field with refractory brick, and in particular to a kind of fire resisting of stabilization pouring pressure Brick.

Background technology

Refractory brick is always a kind of important instrument of metal casting molding environment, and the material and structure of refractory brick are directly affected To the quality of finished metal ingot, refractory brick as far as is known, in casting process, it usually needs polylith refractory brick is connected into shape Into potting syrup runner, and refractory brick is more, destabilizing factor more easily occurs, so often there is refractory brick deformation intolerant to steel The situation that water washes away, the linking between refractory brick is not tight, also often has that excessive air is invaded or steel water overflows from gap The situation of stream occurs, and is not closely that can directly result in finished product bottom to have scarce particularly when refractory brick is connected with the inlet of mould Fall into, it is cylinder that especially traditional refractory brick hollow duct manufacture is unified, when potting syrup enters refractory brick from center toward surrounding The runner of the inside, in the process of circulation, in the case that potting syrup is certain, the pressure fluid pressure of the potting syrup of outermost end is smaller, The speed for causing potting syrup to rise in mould is slower, and the finished product cast inhomogeneous cooling for ultimately forming is even, and quality is not good.

Utility model content

To solve above technical problem, the utility model provides a kind of refractory brick of stabilization pouring pressure.

To achieve the above object, the technical solution of the utility model is as follows：

A kind of refractory brick of stabilization pouring pressure, it is characterized by the brick body including cuboid, along axle in the brick body Hollow runner is provided with to direction, the runner is tapered, the end face of brick body is run through at the two ends of the runner, described tapered Runner cone bottom one end is inlet through brick body position, and described tapered runner vertex of a cone one end is provided with outwardly hollow cone The public entablature of platform shape, the public entablature is engaged with the inlet, and array distribution has hollow circle on an axial plane of brick body Column pours fluid passage, and described to pour that fluid passage is vertical with runner, the one end for pouring fluid passage connects with runner sealing, the other end is vertical Through the surface of brick body.

Using above structure, brick body is in cuboid, it is easy to be fixed on teeming stage, stability is had more during cast, is led to The tapered runner for setting is crossed, the loss of potting syrup Fluid pressure in the runner process of circulation can be greatly reduced, in potting syrup In comparatively ideal pouring temperature range, it is ensured that cast liquid energy is quickly entered in mould by pouring fluid passage, is effectively improved and is poured into The quality of product, sets multiple and pours liquid mouthful in the same axial plane of brick body, the efficiency of cast can be improved, while this kind of refractory brick can also pass through Public entablature polylith in frustum is connected, and linking air-tightness is preferable.

As preferred：The fluid passage that pours has the epitaxy part for axially extending.Using above structure, during cast, epitaxy part Vertically upward, the opening of mold bottom is directly inserted into epitaxy part, so when steel liquid enters mould from epitaxy part top Inside, increased the air-tightness at bottom liquid inlet mouthful.

As preferred：Inflated diameter in the public entablature is consistent with the cone top export diameter of the runner.Use with Upper structure, the two diameter is the same, when needing for polylith brick to be connected cast, it can be ensured that potting syrup will not occur at public entablature Fluid pressure loss situation, while the phenomenon of leakage will not occur.

As preferred：The outer end of the public entablature is provided with dismountable baffle plate.One block of refractory brick is only needed to be poured into a mould When, the vertex of a cone end seal of runner to be lived with baffle plate, potting syrup just can from the bottom up enter mould from fluid passage is poured, when needing polylith resistance to When firebrick is poured into a mould, baffle plate of dismantling, at another piece of inlet of refractory brick of insertion, you can linking is poured into a mould.

As preferred：Brick body is main to be formed by refractory clay calcining.Formed using refractory clay calcining, be added without it Its chemical agent, is conducive to keeping the pure property of potting syrup, and its manufacturing cost is lower.

Compared with prior art, the beneficial effects of the utility model are：

The refractory brick of the stable pouring pressure that the utility model is provided, changes the structure of traditional cast refractory brick, will Hollow runner is arranged to taper, reduces potting syrup flowing pressure loss in runner, can be with active balance potting syrup in mould Poring rate in tool, will not be slow because of being poured into a mould away from cast injection center, cause inhomogeneous cooling even etc., while by setting Put and individually pour fluid passage, the direct gate of potting syrup enters in mould, and air-tightness is better, improve cast efficiency simultaneously, energy Preferably ensure final product quality.

Brief description of the drawings

Fig. 1 is the stereogram of the embodiment of the utility model one；

Fig. 2 is embodiment illustrated in fig. 1 front view.

Specific embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

The refractory brick of the stable pouring pressure with reference to shown in Fig. 1 and 2, the brick of the cuboid calcined by refractory clay Hollow tapered runner 2 is in axial direction equipped with body 1, runner 2 runs through the both ends of the surface of brick body 1, the vertex of a cone one of the runner 2 The public entablature 22 of outwardly hollow taper type, public entablature 3 and the cone of runner 2 bottom one end are provided with the brick body 1 at end vertically Inlet 21 is adapted, and the inflated diameter in public entablature 22 is consistent with diameter at the cone top export of the runner 2, in public entablature 22 Outer end exit be provided with dismountable baffle plate 221, what an axial plane of brick body 1 was provided with four hollow cylindricals pours fluid passage 3, Pour that fluid passage 3 is vertical with runner 2, the one end for pouring fluid passage 3 connects with the sealing of the runner 2, and the other end extends vertically through the axle of brick body 3 Face, pouring fluid passage 3 has the epitaxy part 31 for axially extending.

The course of work of the present utility model is as follows：

Brick body 1 is lain in a horizontal plane in the passage of the teeming stage for making, and makes to pour fluid passage 3 vertically upward, it is ensured that baffle plate 221 are in closed state, bottom is provided with into four moulds in hole just to epitaxy part 31 and is inserted, and make at the outer end of epitaxy part 31 In mold cavity, then fluid injection is started by total pouring platform, liquid enters from the inlet 21 of the runner 2 of taper, because stream The vertex of a cone end in road 2 is sealed by baffle plate 221, so the potting syrup in runner 2 under pressure can only be upward by pouring fluid passage 3 Flowing enters mould inside by bottom, because the linking without refractory brick, reduces because of the error that air-tightness causes, meanwhile, pour Fluid injection enters from the end of inlet 21, and the flowing in the runner 2 of taper, the diameter in runner 2 is gradually reduced, and can effectively ensure that fluid Flowing velocity, it is ensured that cast progress is consistent in each mould, so that the stability of improve product quality.

Finally it should be noted that foregoing description is only preferred embodiment of the present utility model, the ordinary skill of this area Personnel on the premise of without prejudice to the utility model objective and claim, can make various under enlightenment of the present utility model Similar expression, such conversion is each fallen within protection domain of the present utility model.
