Preparation method of sliding plate bricks without iron shells and asbestos boards

Abstract

The invention discloses a preparation method of sliding plate bricks without iron shells and asbestos boards. The preparation method comprises the following steps that raw materials are prepared, wherein compounding and mixing are conducted on the required raw materials; molding is conducted, wherein the raw materials prepared and mixed in the step (1) are compressed into sliding plate brick green bricks; sintering is conducted, wherein the sliding plate brick green bricks are sintered into the sliding plate bricks in a kiln; iron hoops are assembled, wherein the iron hoops and the sliding plate bricks are thermally matched; rough machining is conducted, wherein the sliding plate bricks are punched, roughly ground and dried; zirconium ring embedding is conducted, wherein zirconium rings are embedded into air holes; fine grinding is conducted, wherein the sliding plate bricks are finely ground to a specified size; product inspection is conducted, wherein the physical and chemical properties of the sliding plate bricks are checked, the qualified sliding plate bricks enter the next process, and the unqualified sliding plate bricks are scrapped; coating is conducted, the sliding plate bricks which are inspected to be qualified are coated with heat insulation materials; and inspecting and warehousing are conducted, wherein the appearances of the sliding plate bricks are inspected. The invention aims to provide the preparation method of the sliding plate bricks without the iron shells and the asbestos board, and the preparation method has the advantages that the product quality is ensured, the machining procedures are reduced, the yield is improved, the cost is reduced and the efficiency is obviously improved.

Description

technical field [0001] The invention relates to the field of inorganic non-metallic refractory materials based on alumina, magnesia and carbon, and more specifically relates to a method for preparing a sliding brick without an iron shell and an asbestos board and the preparation method thereof. Background technique [0002] At present, the skateboard bricks in the prior art all use iron shells or asbestos boards to assist and protect the skateboard brick body. Although these auxiliary spare parts have certain functions on the brick adobe, they have serious problems in the process of production and processing. Asbestos The board is easy to detach, and the high-temperature glue is easy to adhere to the joints, which will easily lead to the hidden danger of steel clamping and steel penetration. In addition, when the iron shell is assembled on the skateboard brick, due to the poor flatness of the iron shell, after lathe processing, the iron shell is partially It is scrapped due ...

[0002] At present, the skateboard bricks in the prior art all use iron shells or asbestos boards to assist and protect the skateboard brick body. Although these auxiliary spare parts have certain functions on the brick adobe, they have serious problems in the process of production and processing. Asbestos The board is easy to detach, and the high-temperature glue is easy to adhere to the joints, which will easily lead to the hidden danger of steel clamping and steel penetration. In addition, when the iron shell is assembled on the skateboard brick, due to the poor flatness of the iron shell, after lathe processing, the iron shell is partially It is scrapped due to car wear or partial car processing is not in place; at the same time, the more processes, the labor costs and the waste of auxiliary materials are not a small number, the production and processing costs of the product increase, and the product's competitiveness in the market weakens
