Embodiment 1

[0026] Embodiment 1: as image 3 , 4 As shown in , 5, the composite layer rotary kiln castable prefabricated block is composed of two layers, the high temperature resistant outer layer 1 and the light heat insulation inner layer 2, and the high temperature resistant outer layer 1 and the light heat insulation inner layer 2 An anchoring inner rib 3 is provided, and an arc-shaped groove 4 is respectively formed on both sides of the castable prefabricated block. There are two anchoring inner ribs 3, and the shape is "M" shape as shown in the figure. The top of the anchoring inner reinforcement 3 is at the bottom 2 / 3 of the castable prefabricated block, and the lower part protrudes 40mm from the composite layer castable prefabricated block, and the diameter of the anchoring inner reinforcement is 10mm or 12mm. Arc-shaped grooves are arranged at 1 / 2 of both sides of the castable prefabricated block, and the radius of the arc is 25mm.

Abstract

This invention relates to a rotary kiln cast material precast block. It is compounded by high temperature proof outer layer and light quality heat insulation and preservation inner layer. Anchoring inner tendon is set between the two layers; an arc groove is set on both lateral faces of the precast block. The rotary kiln cast material precast block in this invention can also be consisted by high temperature proof outer layer and anchoring inner tendon, anchoring inner tendon is set in high temperature proof outer layer and an arc groove is set on both lateral faces of the precast block. This invention also provides a method of manufacturing the above precast block. The problem of difficult processing of inner liningof rotary kiln, long consumption time, high labor intensity, expensive cost of erecting framework is solved. And the problem of short life, high failure rate, no long time stable running in production running is also solved.

Description

technical field [0001] The invention relates to a new castable prefabricated block for the inner lining of a rotary kiln, in particular to a castable block prefabricated outside the kiln with the castable and baked at low temperature. The invention also relates to a manufacturing process of the composite layer casting material prefabricated block. Background technique [0002] At present, in the construction of the castable lining of the rotary kiln, the commonly used method is to weld a number of "Y" anchor nails in the rotary kiln in advance according to the specified position, and then evenly distribute the supporting formwork into several strips, and then vibrate, form and maintain them one by one. . Its disadvantage is that the vibration molding of the adjacent one is carried out after the first vibration molding is completed, and the influence of resonance will affect the castable prefabricated strip after the last vibration molding (the crystallization of the castabl...
