Abstract
The utility model belongs to the field of ferrous metallurgy hot-rolling heating furnace, and particularly discloses a hot-rolling heating furnace discharge end wall which comprises a snake-shaped water cooling pipe wall and is characterized in that the discharge end wall consists of an upper layer and a lower layer, wherein the lower layer is the snake-shaped water cooling pipe wall, and the upper layer is a moving layer and formed by pilling-up of refractory bricks. The utility model solves the problem that when two ends of each plate blank are discharged and a cantilever is overlarge, the downward winding part of two ends are blocked by the discharge end wall to clamp a furnace door, thus causing serious production accidents.
Description
Technical field
The utility model belongs to Ferrous Metallurgy hot-rolling heating furnace field.
Background technology
Hot-rolling heating furnace in the iron and steel metallurgical industry in the design of stove discharging headwall, all is to adopt snakelike water cooling tube to make skeleton to support for a long time, and skin is built with low cement deposit material.This structure is feasible in general straight carbon steel production, but the production of continually developing along with the silicon steel kind, the drawback of this structure just reveals, mainly be that silicon steel produces moderate finite deformation by when heating in stove, owing to go into the location, stokehold, and factor affecting such as sideslip in the stove, when the slab two ends cantilever occurs when excessive, down around the maximum raising height that highly surpasses extractor, to be stopped by the discharging headwall around part under the two ends when this moment, slab was come out of the stove, can not come out smoothly, if operating personnel find untimelyly will directly cause slab to be stuck in stove gate, can cause slab to fall into the stove gate bottom when serious, serious production accident taking place, deal with very difficulty, directly causes production line to stop production the processing accident.
Summary of the invention
The purpose of this utility model is to address the above problem and a kind of hot-rolling heating furnace discharging headwall is provided, this discharging headwall can not make the slab two ends in that cantilever is excessive when coming out of the stove, stopped by the discharging headwall around part under the two ends, block stove gate and cause serious production accident.
The technical scheme that the utility model adopted is:
A kind of hot-rolling heating furnace discharging headwall comprises snakelike water cooling tube wall, and described discharging headwall comprises two-layer up and down, and described lower floor is snakelike water cooling tube wall, and described upper strata is a mobile layer, is piled up by refractory brick to form.
Preferably, described refractory brick is alumina firebrick.
The utlity model has following advantage:
This hot-rolling heating furnace discharging headwall is divided into the upper and lower, the upper strata is a mobile layer, pile up by alumina firebrick and to form, under slab around highly excessive, when exceeding discharging headwall mobile layer, because mobile layer is to build form by laying bricks or stones by the alumina firebrick routine, slab can rush open mobile layer easily, slab just can normally be drawn out of, and can the accident of meeting accident not cause stopping production.When treating next shutdown maintenance, a mobile layer structure repair that only needs to destroy gets final product, thereby has improved the security performance of discharging headwall to greatest extent.This discharging headwall upper strata easy construction, cheap simultaneously.
Description of drawings
Fig. 1 is a hot-rolling heating furnace part-structure schematic diagram;
Fig. 2 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
The hot-rolling heating furnace part-structure is with reference to Fig. 1, and the discharging headwall is below discharging stove gate 2, and slab is retracted on the discharging Kun road 3 by discharging headwall and discharging stove gate 2.
With reference to Fig. 2, the discharging headwall is divided into the upper and lower, and lower floor is snakelike water cooling tube wall 1, and snakelike water cooling tube wall is to do skeleton by snakelike water cooling tube 4 to support, and skin is built with low cement deposit material.The upper strata is a mobile layer 5, is piled up by alumina firebrick to form.
Around highly excessive, when exceeding discharging headwall mobile layer 5, slab rushes open mobile layer 5 under slab, and slab can normally be extracted on the discharging Kun road 3 this moment.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
Claims (2)
