Abstract
The utility model relates to a door of industrial furnace, aiming at solving the deficiency in the prior art, such as spalling in large area, loosening, cracking, eroding and wearing of refractory lining refractory. The furnace door comprises a steel structure object (1), a steel plate (2) connected with the steel structure object, a metal riveting firmware (3) connected with the steel plate (2), a refractory castable work layer (4), a heat-insulation layer (5) between the refractory castable work layer (4) and the steel plate (2). The utility model is characterized in that a refractory castable riveting cylinder (6) is wrapped on the outside of the metal riveting firmware (3) and is connected with the steel plate (2), at least one groove (7) is arranged on the surface of the refractory castable riveting cylinder (6). The utility model has the advantages of the reasonable structure, the convenience of construction, the excellent whole performance of refractory lining with uneasy spalling ability, high thermal shock stability, well thermal insulation ability, and longer life than prior art.
Description
Technical field
The utility model relates to the industrial furnace fire door, specifically belongs to industrial furnace fire door refractory material lining structure.
Background technology
Industrial furnace is the visual plant of nonferrous metallurgy, iron and steel industry and mechanical industry, and fire door then is the vitals that constitutes industrial furnace, is undertaking keeping and furnace charge task such as come out of the stove of furnace atmosphere and high temperature.Because fire door will be subjected to opening and closing operations repeatedly, make its working environment that is in mechanical shock, collision and high temperature rapid heat cycle all the time, make fire door refractory material lining be easy to generate thermal shock and peel off problem with mechanical damage, cause stop work and production.People are in order to overcome the deficiency of its existence, carried out big quantity research, as, strengthen fire door refractory material lining globality, adopt integrated poured technology, whole ramming technology, good castable refractory or the fire-resistance rammed mass technology of thermal shock resistance, and obtained better effects, promptly prolonged fire door service life; Also have from improving the heat-proof quality of fire door refractory material lining, worked out the compound Lining structure of refractory material working lining and insulation layer, equally also prolonged fire door service life.Though but these improvement technology improved fire door life cycle, but compare with the life cycle and the heat insulating effect of industrial furnace integral body, still there are deficiencies such as refractory material lining large tracts of land is peeled off, become flexible, cracking, erosive wear in fire door, when serious even refractory material is served as a contrast burn.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of refractory material lining good integrity, long service life, insulation and heat-proof quality good novel fire door refractory material lining
Realize the technical measures of above-mentioned purpose:
Novel fire door refractory material lining, main by the insulation layer between steel construction piece, the steel plate that is connected with steel construction piece, the metal riveting component that is connected in steel plate, castable refractory working lining, steel plate and the castable refractory working lining), it is that castable refractory rivet clasp cylinder is wrapped in metal riveting component outside, and be connected with steel plate, there is at least one groove on the surface of castable refractory rivet clasp cylinder.
Its shape that is castable refractory rivet clasp cylinder (6) can be circle, ellipse and polygon according to the door structure form.
It is that castable refractory rivet clasp cylinder adopts the heavy castable refractory around the direct moulding by casting of metal riveting component.
It is that the castable refractory working lining adopts the light fibre castable refractory.
The utility model is rational in infrastructure, easy construction, refractory material lining overall performance is good and incrust, thermal shock resistance is high, heat insulation property good, and service life is longer than prior art.
