Description

Ceramic pouring system suitable for cast steel roller

Technical Field

The utility model belongs to the technical field of the roll manufacturing technique and specifically relates to a pottery gating system suitable for cast steel roll.

Background

The cast steel roller of the company adopts static casting and bottom casting production, and molten steel flows through a pouring cup, a sprue, a cross gate, a lower roller neck of the roller, a roller body and an upper roller neck of the roller during production. The clay bricks of the prior cast steel roll casting system are matched by adopting rabbets, so that a single clay brick is heavy in quality, and the bottom box is high in labor intensity and production cost during molding.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned defect, provide a ceramic gating system suitable for cast steel roll.

The utility model adopts the technical proposal that:

a ceramic gating system adapted for casting steel rolls, comprising: the pouring straight pipe is connected with the tangent brick through the equal-diameter joint, and the sprue is connected with the cross gate through the pouring bent pipe.

The utility model discloses technical scheme's further improvement lies in: the cross pouring channel is communicated with the bottom box cavity through the thread cutting brick.

The utility model discloses technical scheme's further improvement lies in: the constant diameter joint is a socket joint.

The utility model discloses technical scheme's further improvement lies in: the flow inner diameter of the socket joint is generally consistent with the inner diameters of the pouring straight pipe, the pouring bent pipe and the tangent brick.

The utility model discloses technical scheme's further improvement lies in: the pouring straight pipe, the pouring bent pipe, the tangent brick and the equal-diameter joint are all made of ceramics.

Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:

the utility model discloses wall thickness is thin, light in weight, satisfies the operation requirement of the cast steel roll under casing of different inner chamber sizes, and need not take out from the under casing after the molding finishes, and production efficiency is high, low in labor strength.

The utility model discloses an adjustment pouring straight tube, the quantity that connects of constant diameter satisfy the operation requirement of the roll under casing of different inner chamber sizes, can adapt to the ceramic gating system of the cast steel roll of different specification models.

Possess and can be through the ceramic gating system of adjustment constant diameter joint, pouring straight tube quantity, make this system avoid producing the phenomenon that molten steel leaks outward, molding sand gets into the molten steel when the pouring, stop the material waste, practice thrift the cost expenditure.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts;

FIG. 1 is a schematic sectional view of the structure of the present invention;

FIG. 2 is a schematic sectional view A-A of the present invention;

the pouring device comprises a bottom box 1, a bottom box 2, a cold mould 41, a pouring cup 42, a sprue 43, a pouring elbow 44, a cross runner 45 and an equal-diameter joint.

Detailed Description

The present invention will be described in further detail with reference to the following examples:

a ceramic gating system adapted for casting steel rolls, the system comprising: a bottom box 1, a sprue 42 and a runner 44.

Wherein, the sprue 42 includes the constant diameter joint 45 and pours the straight tube, pours the straight tube and is connected with the constant diameter joint 45, and the runner 44 includes constant diameter joint 45, pours the straight tube and cuts the line brick, and the pouring straight tube passes through constant diameter joint 45 and is connected with tangent line brick, and the sprue 42 passes through pouring return bend 43 and is connected with runner 44.

Specifically, the system can be used for adjusting the number of the straight pouring pipes through the equal-diameter joint 45, so that the phenomena that molten steel leaks outwards and molding sand enters the molten steel during pouring are avoided, material waste is avoided, and cost expenditure is saved.

Furthermore, the cross pouring channel 44 is communicated with the cavity of the bottom box 1 through a line cutting brick, the line cutting brick is connected with the cross pouring channel 44 through a bellmouth joint, and the bottom pouring type pouring system 4 with the line cutting brick is provided, so that impurities can float upwards conveniently in the pouring process of molten steel, and the surface quality of a product is good.

Further, the constant diameter joint 45 is a socket joint, and the sprue 42, the pouring bend 43 and the runner 44 are sockets to be connected with the socket joint.

Furthermore, the flow inner diameter of the bell mouth joint is approximately consistent with the inner diameters of the pouring straight pipe, the pouring bent pipe 43 and the tangent brick, so that molten steel can flow smoothly in the bottom pouring type pouring system 4, and the resistance is reduced.

Further, the cast straight tube, the cast bent tube 43, the tangent brick and the constant diameter joint 45 are all made of ceramics.

In the embodiment, the matching of the pouring straight pipe and the equal-diameter joint meets the bottom box 1 with the size of the inner cavity.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
