Description
Technical Field
The invention relates to the technical field of ceramic composite roller skin casting, in particular to an anti-crack ceramic composite roller skin casting system.
Background
In the production process of the grinding roller of the easy-to-wear part of the medium-speed coal mill used in a coal-fired power plant, a roller leather embedding composite casting method is adopted in the process. The roller skin is formed by compounding ceramic honeycomb grids and high-chromium cast iron. In the compounding process of the ceramic honeycomb grids and the high-chromium cast iron, because the difference between the thermal expansion systems of the ceramic honeycomb grids and the high-chromium cast iron is large, cracks are often generated on the surface of the roller skin in the cooling process after the composite casting.
Disclosure of Invention
The invention aims to provide an anti-crack ceramic composite roll skin casting system, which solves the problem that cracks are generated on the surface of a roll skin.
In order to solve the technical problems, the invention adopts the following technical scheme: an anti-cracking ceramic composite roll skin casting system comprises a roll skin cavity, a middle cross gate, a left side cross gate, a right side cross gate, a riser, a sprue and an air outlet sheet; both ends of the middle horizontal pouring gate are provided with a roller skin cavity; the two sides of the middle cross gate are respectively provided with a left side cross gate and a right side cross gate, and the middle cross gate is communicated with the left side cross gate and the right side cross gate; two ends of the middle horizontal pouring gate, the left horizontal pouring gate and the right horizontal pouring gate are respectively communicated with roller skin cavities positioned at two ends of the middle horizontal pouring gate; a pouring gate is arranged on the middle horizontal pouring gate; and risers are arranged on the left side cross gate and the right side cross gate.
Furthermore, a plurality of air outlet sheets are arranged on the roller skin cavity; the air outlet sheet is arranged on the inner side of the roller skin cavity.
Further, when a ceramic composite roll skin casting system is adopted, after molten iron enters from a sprue in the middle of a middle cross gate, the molten iron enters a left side cross gate and a right side cross gate; molten iron enters the left side cross gate and the right side cross gate through the middle cross gate and is divided into three paths to enter the roller shell cavity, and step casting is formed.
Further, when bubbles are generated in the casting process, air is exhausted through the air outlet piece on the roller skin cavity.
The invention has the beneficial effects that: the invention adopts a structural form that one mould is provided with two parts, water is fed in the middle, and two ends of the mould are provided with risers, and molten iron enters a roller shell cavity in three ways after entering from a middle pouring gate, which is similar to step casting. After a middle cross gate is added, the left, middle and right parts of the two roller skin cavities are connected after forming, and cracks caused by deformation in the cooling process are avoided.
In addition, the air outlet piece is additionally arranged above the roller skin cavity and is designed on the inner side of the roller skin cavity, so that the air outlet effect is improved, and the phenomenon of poor casting and infiltration caused by bubbles of the ceramic honeycomb grids is avoided
Drawings
The invention is further illustrated by the following figures and examples.
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described by the following detailed description.
Referring to fig. 1, the crack-resistant ceramic composite roll skin casting system comprises a roll skin cavity 1, a middle cross gate 2, a left cross gate 3, a right cross gate 4, a riser 5, a gate 6 and an air outlet sheet 7; two ends of the middle horizontal pouring gate 2 are respectively provided with a roller skin cavity 1; a left side cross gate 3 and a right side cross gate 4 are respectively arranged on two sides of the middle cross gate 2, and the middle cross gate 2 is communicated with the left side cross gate 3 and the right side cross gate 4; two ends of the middle cross gate 2, the left side cross gate 3 and the right side cross gate 4 are respectively communicated with roller skin cavities at two ends of the middle cross gate; a pouring gate 6 is arranged on the middle horizontal pouring gate 2; and risers 5 are arranged on the left side cross gate 3 and the right side cross gate 4.
A plurality of air outlet sheets 8 are arranged on a roller skin cavity 1; the air outlet sheet is arranged on the inner side of the roller skin cavity 1.
The invention adopts a structural form that water is fed into the middle of one die and two parts are fed into the middle of the die, and two ends of the die are provided with dead heads, when a ceramic composite roll skin casting system is adopted, molten iron enters a left side cross pouring gate and a right side cross pouring gate after entering from a pouring gate in the middle of a middle cross pouring gate; molten iron enters the left side cross gate and the right side cross gate through the middle cross gate and is divided into three paths to enter the roller shell cavity, and step casting is formed. . After a middle cross gate is added, the left, middle and right parts of the two roller skin cavities are connected after forming, and cracks caused by deformation in the cooling process are avoided.
In addition, the air outlet piece is additionally arranged above the roller skin cavity and is designed on the inner side of the roller skin cavity, so that the air outlet effect is improved, and the phenomenon of poor casting and infiltration caused by bubbles of the ceramic honeycomb grids is avoided. The vent plate is designed on the inner side (the ceramic honeycomb grid is arranged on the outer side), so that cracks generated by the tension of the vent plate on the high-chromium covering layer of the grid in the cooling process are avoided.
