Description
Technical field
The invention belongs to industrial furnace technical field more particularly to a kind of new type high temperature ceramic fibre liners.
Background technique
Industrial furnace largely uses in all trades and professions, it is the heat converted using fuel combustion or electric energy, by material
Or the Thermal Equipment of workpiece heating.The chief component of industrial furnace has：Brickwork of industrial furnace, fume dischange system for industrial furnace, industrial furnace
Preheater and combustion device for industrial furnace etc..Brickwork of industrial furnace is by furnace roof masonry, masonry for furnace wall and masonry of well composition, all blocks
Body is made of refractory material.
High-temperature ceramic fibre is a kind of energy-saving and environment-friendly refractory material that developed recently gets up.It is a kind of fibrous light
Refractory material has many advantages, such as that light-weight, high temperature resistant, thermal stability are good, thermal conductivity is low, specific heat is small and mechanical resistant vibration, often
Insulating layer in industrial furnace masonry, but there are life problems when in use in overall height temperature ceramic fibre liner, this is multi-party
Caused by the reason of face, first is that inherently a kind of non-crystalline state of ceramic fibre, under high-temperature situation, this non-crystalline state
Fiber can form crystal at leisure and dusting, the speed of the process are related to temperature, use especially as working lining liner
Ceramic fibre bears some uncontrollable temperature changes, if combustion gas is burnt on ceramic fibre surface, causes fiber surface temperature super
Height aggravates local fiber dusting；Two are subject to washing away for air-flow；Third is that in burner hearth slag erosion etc..These factors will be made
Help the problems such as ceramic fibre liner shrinks, falls off, heat insulating ability substantially reduces, finally can only shutdown maintenance replacement, therefore having must
Improvement is designed to it.
Summary of the invention
The present invention is to solve well-known technique and provide a kind of new type high temperature ceramic fibre liner.
The present invention is adopted the technical scheme that solve well-known technique：A kind of new type high temperature ceramics

Further, the ceramic fiber layer is suppressed by multiple ceramic fiber blankets.
Further, the end surface of the fixed link is equipped with external screw thread.
Further, the refractory slab is chlorine oxygen magnesium fire-proof plate.
Further, the spring is brute spring.
The present invention has the advantage that as follows with good effect：
1. a kind of new type high temperature ceramic fibre liner proposed by the present invention, by the way that fire resisting is arranged in the outside of ceramic fiber layer
Plate can effectively avoid contact of the open fire with ceramic fiber layer, ceramic fibre avoided to incinerate at high temperature, to greatly improve it
Service life.
2. a kind of new type high temperature ceramic fibre liner proposed by the present invention, is cased with telescopic rod by the end in fixed link,
Spring is cased on the outside of telescopic rod, this kind design may make heat-preservation cotton, ceramic fiber layer and refractory slab contact close, avoid revolving
Tight nut influences heat insulation for a long time in use, tightening nut pitches.
