High-erosion-resistance lip brick for glass kiln and preparation method of high-erosion-resistance lip brick

Abstract

The invention discloses a high-erosion-resistance lip brick for a glass kiln and a preparation method of the high-erosion-resistance lip brick, the high-erosion-resistance lip brick comprises a lip brick body, the lip brick body is composed of an upper lip brick and a lower lip brick, fixing strips are arranged on the lower lip brick at equal intervals, fixing grooves are formed in the lower portion of the upper lip brick at equal intervals, the fixing grooves are clamped with the fixing strips, and an inclined plane is arranged on the upper lip brick. Two layers are arranged during processing of the lip brick, the upper lip brick has excellent corrosion resistance and fire resistance, good thermal shock resistance, low porosity, good volume stability and high strength can be guaranteed, corrosion of glass to the lip brick can be improved, the overall service life is prolonged, the lower lip brick is made of basic materials, and the cost is low. Not only can the processing cost be reduced, but also proper lip bricks can be produced according to actual conditions and can be reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of lip bricks, in particular to a high-corrosion-resistant lip brick for a glass kiln and a preparation method thereof. Background technique [0002] With the wide application of solar energy, the production of rolled glass used in some solar devices is increasing day by day, and the lip brick is an important forming part of the rolled glass production line, and its use environment is very harsh. Usually, the service temperature of the lip brick is: 1180-1200°C on the contact surface with the glass liquid, and 600-700°C on the non-glass liquid contact surface, because the lip brick is longer. Lip bricks must have the following properties: (1) Small dimensional tolerance and small deformation in the section, and the deformation in the length direction after burning should not exceed 3mm; (2) It must have good thermal shock stability; (3) It must have good alkali corrosion resistance . At present, the method...

AI Technical Summary

Problems solved by technology

[0004] In actual use, the corrosion resistance and high temperature resistance of the lip brick only need to ensure that the end face in contact with the glass ensures better excellence, and the end face that does not contact only needs to ensure basic performance. And refractory technology, because it needs to be replaced frequently, it will increase the cost of processing, and the performance of lip bricks cannot be fully utilized
