Fiber module for heating furnace and manufacturing method for fiber module

Abstract

The invention discloses a fiber module for a heating furnace and a manufacturing method for the fiber module. The fiber module comprises a body consisting of a fiber blanket and is characterized in that: the body is formed by flatly paving the fiber blanket and folding the fiber blanket for many times along a length direction or a width direction or flatly paving a plurality of fiber blankets in a staggered manner and folding the fiber blankets for many times along directions of staggered gaps; in the body, a plurality of hangers are arranged; the hangers are fixedly connected with the body; and fixed clamping plates are arranged on two side faces of the body. By the fiber module of the heating furnace, the shortcomings that a furnace lining has shorter service life, the fiber module on the top of the furnace or a fiber folding block is easy to fall off and difficult to repair and the like of the conventional heating furnace can be overcome; the gaps of the fiber module in a compression-free direction (the length direction) can be reduced to the maximum extent; at high temperature, the fiber module has higher adaptability and has an outward extending function, so that the same distance between two ends of the fiber module can be substantially kept in the length direction; and the two ends of the fiber module cannot be inwardly contracted substantially.

Description

technical field [0001] The invention relates to a fiber module used as a furnace top lining on an industrial heating furnace, in particular to a fiber module used for a high-temperature heating furnace for heating workpieces and a manufacturing method thereof. [0002] Background technique [0003] In the field of thermal processing, such as forging and rolling of the workpiece, it is necessary to use a heating furnace, place the workpiece in the heating furnace and heat it to the required temperature, and then perform the operation of the thermal processing process; in order to achieve the effect of heating and heat insulation, in The furnace top of the heating furnace must be provided with heat-insulating and fireproof linings. In the heating furnaces of the prior art, the furnace lining of the furnace roof usually adopts an all-fiber module structure, and several pieces of all-fiber module linings are densely distributed on the furnace roof as a refractory material layer...

AI Technical Summary

Problems solved by technology

[0007] The present invention aims at the fiber module of the heating furnace in the prior art, and cannot avoid the state of non-uniform gaps formed between adjacent fiber modules or fiber folded blocks due to the shrinkage of the refractory fiber material at high temperature, and the flame jumps up from the gap and burns out. Fix the anchors, screws, furnace roof steel plates and other parts of the fiber module or fiber folding block, shorten the service life of the furnace lining, the fiber module or fiber folding block on the top of the furnace is easy to fall, difficult to repair, etc., and provide a method that can minimize no compression Long fiber module for heating furnace with directional slit and manufacturing method thereof
