Problems solved by technology

However, the refractory bricks disclosed in this application are formed by extruding various powders through a molding machine, and various powders will be unevenly mixed when mixed, that is, various returned materials cannot react uniformly during sintering. Thus affecting the performance of the prepared bricks, the produced bricks are prone to cracks or missing corners
[0008] And the production process currently used to produce paving bricks for glass kilns is mainly single-block production, that is, only one paving brick can be produced in one sand mold, so the qualified rate of paving bricks produced in this way is low, and the area occupied by the riser of the product is relatively small. Large, which increases the production cost, only a small amount of sand mold can be placed in the incubator, that is, the production efficiency is very low, which increases the production cost and delays the production cycle

Abstract

The invention provides paving bricks for a glass kiln and a production process thereof. The paving bricks are prepared from the following raw materials in parts by weight: 30-50 parts of natural zircon sand, 30-50 parts of aluminum oxide powder, 1-3 parts of sodium carbonate, 1-5 parts of fluorite powder, 2-8 parts of silica powder and 8-16 parts of titanium dioxide. By controlling the proportionof the components reasonably and selecting an insulating material reasonably, the prepared paving bricks have excellent performance. In the embodiment process, the sand form of the prepared sand is improved. 15 paving bricks can be produced at one time in one insulating oven after the sand form is improved. The paving bricks are good in quality and high in percent of pass. In the production process, the paving bricks need not to be melted frequently, so that scattering of a feed liquid is reduced, the casting time is shortened and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the production technical field of paving bricks, in particular to a paving brick for a glass kiln and a production process thereof. Background technique [0002] All material products that can be used in kiln masonry projects and have a melting point higher than 1588°C are collectively referred to as "refractory products" and are also called refractory bricks. Refractory bricks can be divided into clay, high alumina, Silicon, semi-siliceous, magnesium, magnesium aluminum, magnesium silicon, magnesium chromium, dolomite, corundum, zirconium corundum, mullite, zirconium mullite, quartz, alumina and silicon carbide etc. [0003] Refractory materials refer to inorganic non-metallic materials with a refractoriness of at least 1500°C. Refractoriness refers to the temperature in centigrade at which a refractory conical sample can resist high temperature without softening and melting under the condition of no load. Refractory materi...
