Abstract

The invention discloses a production process of a fused quartz ceramic roller way. The preparation process comprises the following step: S1, preparation of a base material, namlely, mixing fused quartz powder and ceramic according to a mixing ratio of 2: 1, adding clay, putting the mixture into a calcining furnace, carrying out calcining treatment at a calcining temperature of 1000-1200 DEG C for1-2 h, and carrying out cooling after calcining so as to obtain the base material. The base material is obtained by mixing fused quartz powder with ceramic first and then adding clay and carrying outcalcining treatment. The clay is prepared by adding high-aluminum clay into a rare earth lanthanum chloride solution, the high-aluminum clay can be used for calcination treatment to promote the combination effect of fused quartz powder and ceramic, and the effect is better after treatment with a rare earth lanthanum chloride solution. The connection degree between the raw materials can be furtherenhanced by adding an adhesive, and then the compression resistance and other strength properties of the material are improved.

Description

technical field [0001] The invention relates to the technical field of quartz ceramic roller tables, in particular to a production process of fused quartz ceramic roller tables. Background technique [0002] The roller table is the main equipment for transporting rolled pieces in the rolling workshop, and its weight accounts for about 40% of the total weight of the equipment in the rolling workshop, and it is the most used equipment in the rolling workshop. Rolled pieces enter and exit the heating furnace, are reciprocally rolled on the rolling mill, and are transported to the finishing process after rolling, etc., are all completed by the roller table. The roller table is a transportation device that uses the rotation of cylindrical rollers to convey the rolled piece. It connects the various processes of the rolling production process with each other. Realize operation mechanization, greatly improve working conditions, increase production efficiency, and provide condition...
