Abstract
The invention provides a magnalium spinelle composite brick, which is a sector block and consists of a little end magnalium spinelle layer and a big end light heat-insulation layer. The thickness A is 98 millimeters, the sector angle B is 6.53 degrees, the radius of an outer circle of the light heat-insulation layer is 2000 millimeters, the radial length of the light heat-insulation layer is 60 millimeters, and the total radial length of the magnalium spinelle layer and the light heat-insulation layer is 230 millimeters. The service life is longer than 2 years.
Description
Technical field
The present invention relates to a kind of magnesium aluminate spinel composite brick, be particularly suitable for building by laying bricks or stones rotary kiln.
Background technology
The Mg-Al spinel brick of existing inner liner of rotary kiln all is a double-layer structure, near the promptly outer lightweight thermal insulation brick that adopts of kliner coating, is that internal layer is a Mg-Al spinel brick by material.Lightweight thermal insulation brick and Mg-Al spinel brick are respectively independently.Build difficulty on the one hand by laying bricks or stones, loosening easily on the other hand, along with the wear down of Mg-Al spinel brick, cause cave-in accident in the kiln easily, the service life of the anti-material of inner liner of rotary kiln is in 1 year.
Summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides a kind of magnesium aluminate spinel composite brick, reach more than 2 years its service life.
The present invention solves the technical scheme that its technical problem takes: it is secter pat, consist of one by the magnesium aluminate spinel of small end and the light heat insulation layer of big end, its thickness A is 98 millimeters, segment angle B is 6.53 degree, the radius of light heat insulation layer cylindrical is 2000 millimeters, light heat insulation layer length radially is 60 millimeters, and magnesium aluminate spinel layer and light heat insulation layer total length radially is 230 millimeters.
The present invention is combined with each other Mg-Al spinel brick and lightweight thermal insulation brick, becomes a brick, and composite brick is divided into light heat insulation layer and magnesium aluminate spinel layer.Guarantee the high temperature and the anti-wear performance of the contactant bed of material on the one hand, guaranteed the effect of heat insulation of contact kliner coating thermal insulation layer on the other hand.Simultaneously masonry quality increases substantially, and has avoided existing two-layer brick loosening easily and owing to the Mg-Al spinel brick wear down problem of caving in use effectively.Bring up to service life more than 2 years.
