High-temperature-resistant corundum mullite roller way plate in kiln cavity of totally-enclosed kiln

Abstract

The invention discloses a high-temperature-resistant corundum mullite roller way plate in the kiln cavity of a totally-enclosed kiln and aims to solve the problem of high probability of kiln arching of the conventional kiln roller way plate. The high-temperature-resistant corundum mullite roller way plate comprises a plurality of corundum mullite bricks which are taken as bottom plates of a roller way kiln, wherein each corundum mullite brick is provided with a plurality of roller grooves; the two ends of each roller groove are provided with corundum bearings; a corundum roller is arranged above each roller groove; and the two ends of the corundum roller are arranged in the corundum bearings respectively. The roller way plate has a small rolling friction coefficient, a simple structure, low manufacturing cost and wide sintering temperature range, can effectively reduce or avoid kiln arching accidents caused by large friction pressure of the kiln or the falling of a hot part into the kiln cavity and is safe and reliable.

Description

technical field [0001] The invention relates to a high-temperature-resistant corundum-mullite roller table in a fully-sealed kiln chamber. Background technique [0002] Most of the existing fully enclosed kiln roller table adopts corundum roller table. Due to the high friction coefficient of corundum, it will cause difficulty in advancing the material during the feeding process of the kiln, and it will be different from the previous ones. The phenomenon of arch kiln occurs when the material phase collides, which affects the production of materials and the use of kiln. At the same time, due to the small bending resistance of corundum, when the mass of the material is large, the corundum roller table will break, which will cause the overall destruction of the kiln cavity. At the same time, when this roller table method is adopted, the friction coefficient of many kilns becomes larger due to the falling of slag, and the sliding coefficient becomes smaller. Difficult to refle...
