Abstract
The utility model relates to a shim plate for a furnace bottom plate of an annealing furnace. A circular metal plate (2) of which the thickness is 20 to 60 millimeters is additionally arranged on a furnace bottom plate (1). The utility model can prolong the service life of the furnace bottom plate, reduce production cost, diminish the width of side waves, have no imprint and make the performance and the quality of products accord with the standard.
Description
The utility model relates to the temper remover in the annealing furnace.
Before the invention, after the drop-bottom in the annealing furnace used a period of time, under the effect of factors such as thermal stress, coil of strip weight and furnace atmosphere, drop-bottom then can produce problems such as distortion, crackle.Because distortion makes the drop-bottom air spots, and make coil of strip produce impression near the end face of drop-bottom side, after the uncoiling then its limit portion formed the local deformation of picture horse-hof shape, thereby influenced the quality of product, can not satisfy the requirement behind the user, at this moment then need in time to change drop-bottom.But drop-bottom is made of high alloy heat-resistance stainless steel material, so cost an arm and a leg, production cost increases.
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can increase drop-bottom service life, reduces production costs, coil of strip can not produce impression, the drop-bottom backing plate of limit wave phenomenon.
Its objective is such realization: be used for the backing plate of annealing furnace drop-bottom, being increased for the service life that makes drop-bottom, set up thickness and be 20～60 millimeters metallic plate on drop-bottom, metallic plate be shaped as circle.
Place metallic plate on the drop-bottom of annealing furnace, can improve the service life of drop-bottom, reduce production costs, limit wave width reduces, and does not produce impression, and the properties of product quality meets standard.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model
Be described in further detail as follows below in conjunction with accompanying drawing: embodiment 1: in the ring-like annealing furnace that the Wuhan Iron and Steel Plant silicon sheet plant adopts, drop-bottom (1) is a plum blossom shape, for increase the service life that makes this drop-bottom (1), the thickness that superposeed on drop-bottom (1) is 41 millimeters circular general carbon plate (2).General carbon plate (2) can in time be changed according to its situation of change of using back plate shape.Embodiment 2: in the bell type annealing furnace that Wuhan Iron and Steel Plant adopts, drop-bottom (1) be circular, and for making the increase in service life of this drop-bottom (1), the thickness that superposeed on drop-bottom (1) is 35 millimeters circular high alloy plate (2).High alloy plate (2) can in time be changed according to the situation of change of using back plate shape.
Claims (1)
1, a kind of backing plate that is used for the annealing furnace drop-bottom is characterized in that setting up thickness and is 20～60 millimeters metallic plate (2) on drop-bottom (1), metallic plate (2) be shaped as circle.
