Abstract
The utility model relates to the structure of an industrial furnace, in particular to a fixed structure of resistance strap or wire in the industrial furnace. The utility model comprises a furnace wall composed of a metal shell and a fire resistant thermal layer and a plurality of fixed columns made of fire resistant pottery materials. The front part of the fixed columns is vertically inserted into the fire resistant thermal layer and the rear part extends out from the interior and is arranged in array. The resistance strap winds the extraction part of the fixed column. The rear end of the fixed column is provided with an end cap whose diameter is greater than the column body and the end cap is blocked inside the resistance strap. The utility model has characteristics of simple structure, convenient manufacture, low cost and long life and can intensify thermal performance so as to quicken temperature rise and reduce power consumption.
Description
Technical field
The utility model relates to the fixed structure of resistive band in the structure of industrial furnace, particularly industrial furnace or resistance wire.
Background technology
Common industrial furnace generally comprises the furnace wall of forming by by metal shell and refractory insulating layer, is mounted with resistive band or resistance wire as heater in furnace chamber.In the industrial furnace of existing structure, the fixed form of its resistive band or resistance wire, be the many Metallic rod (being generally stainless steel material) of in the furnace wall, arranging, Metallic rod one end is fixed on the metal shell, the other end is stretched out by the refractory insulating layer inboard, on this external part, overlap again with insulating part, then resistive band (silk) is hung around on the insulating part.This structure following defective arranged: one, process structure complexity, make processing inconvenience, the manufacturing cost height; Two, because Metallic rod runs through refractory insulating layer, and is connected, thereby heat is lost easily in the heating process, not only makes the power consumption that increased electric furnace, prolonged the electric furnace heating-up time, and easily make the metal shell temperature too high and be out of shape with metal shell; Three, Metallic rod easily oxide etch at high temperature, useful life is short.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of fixed structure of novel industrial furnace resistive band (silk) is provided, make that it is simple in structure, easily manufactured, cost is low, long service life, and can improve the heat-insulating property of electric furnace, make its quick heating, low in energy consumption.
The fixed structure of industrial furnace resistive band of the present utility model includes the furnace wall of being made up of metal shell and refractory insulating layer, it also includes the many fixed levers of being made by refractory ceramic material, the body of rod leading portion of fixed lever vertically is inserted in the refractory insulating layer, fixed lever body of rod back segment stretches out in the refractory insulating layer inboard, and by certain array arrangement, resistive band is promptly on the extension that hangs over the fixed lever body of rod, also have the end cap of a diameter greater than the body of rod in the rear end of the fixed lever body of rod, end cap is blocked in the inboard of resistive band.Also can be with the packing ring that a refractory ceramic material is made at fixed lever body of rod leading portion, this packing ring pad makes their not directly contacts between resistive band and refractory insulating layer.In above-mentioned technical scheme, described refractory insulating layer can adopt refractory fibrous material to make, and the leading portion outer surface at the fixed lever body of rod is provided with tapping screw thread simultaneously, fixed lever can be revolved in the mode of self tapping insert in the refractory insulating layer matrix.
The utility model is compared with existing structure, and it is simple in structure, installation and processing is convenient, low cost of manufacture.Simultaneously do not have metal material to conduct heat between metal shell and the electric furnace inner chamber, thereby reduced heat dissipation, improved the heat efficiency, improved programming rate, avoided metal shell Yin Gaowen and the distortion that produces.In addition, the fixed lever of refractory ceramic material and packing ring corrosion resistance are good, have prolonged useful life.
Description of drawings
Fig. 1 is the planar structure schematic diagram of the utility model in the inboard, furnace wall;
Fig. 2 is that the A of Fig. 1 is to cutaway view.
Embodiment
The utility model is applied in the industrial furnace, as shown in Figure 2, the furnace wall of electric furnace is made up of the refractory insulating layer 2 of outer field metal shell 1 and internal layer, refractory insulating layer is made by refractory fibrous material, the outer surface of fixed lever 3 body of rod leading portions of being made by refractory ceramic material is provided with tapping screw thread 7, fixed lever 3 revolves in the refractory fibrous material that inserts in the refractory insulating layer matrix in the mode of self tapping, fixed lever 3 body of rod back segments are stretched out by refractory insulating layer 2 inboards, and by certain array arrangement (as shown in Figure 1), resistive band 4 (also can be resistance wire) is on the extension that hangs over the fixed lever body of rod, and the body of rod rear end of fixed lever 3 has an end cap 5 to be blocked in the inboard of resistive band.Between resistive band and refractory insulating layer, also be lined with the packing ring 6 that refractory ceramic material is made, make their not directly contacts, avoid burning out refractory fibrous material.
