Abstract
The utility model discloses a steel coil support plate which is a disc steel plate (1). The steel coil support plate is characterized in that grid strips (11) are evenly arranged on the plate along the circumference; an empty slot formed between two adjacent grid strips (11) is a longitude hot air runner (12); the width of each grid strip (11) on the circumference is equal to the distance of the longitude hot air runner (12); two latitude hot air runners (13) are also arranged in the latitude direction; a round hole (14) is formed in the middle of the steel plate (1). The steel coil support plate is simple and practical, easy to operate on the spot, and convenient to maintain, the mobility of the hot air is increased by virtue of the latitude and longitude hot air runners, and the phenomenon of uneven cold and heat inside a cover is improved. Thus, the surface quality of the heat-treated steel coil is improved. Furthermore, the roughness of the contact surface of the support plate and the steel coil is improved, and the friction between the steel coils can be reduced. Thus, deformation of the steel coil is reduced, and the yield is improved.
Description
Technical field
The utility model relates to smelting iron and steel industry, is specially the coil of strip back up pad using in the silicon steel rotary heating furnace of Steel Plant.
Background technology
Coil of strip thermal treatment is carried out heating anneal and is realized under a sealed environment, at present, coil of strip is to be all directly placed on table, directly the flow through inner diameter hole of coil of strip and the outside surface of coil of strip of the hot gas flow being blasted by gas blower from table heats coil of strip, this table heating arrangement can not regulate direction and the airshed of hot gas flow, easily producing the overheated top away from table in coil of strip and the close bottom of table is easily heated insufficient, thereby it is inhomogeneous that process furnace coil of strip is heated, lower deformation is very large, cause scrap rate can not to be in any more, production capacity is low, cost is high.
Utility model content
Be heated evenly in table in order to realize coil of strip, the utility model provides a kind of coil of strip back up pad.The technical solution of the utility model is: be a discoidal steel plate; on steel plate, be provided with barrier bar along even circumferential; the dead slot forming between two adjacent barrier bars is warp-wise thermal current passway, and the width on excircle of barrier bar is identical with the distance of warp-wise thermal current passway; In broadwise, be also provided with two broadwise thermal current passways; Be provided with a circular hole in the centre of steel plate; Described warp-wise thermal current passway and broadwise thermal current passway guide to the hot gas flow being blasted from table the periphery of steel plate equably, the hot gas flow evenly being guided converges on the top of coil of strip with the hot gas flow directly passing through through coil of strip internal diameter from described circular hole, thereby make coil of strip be in one around in the uniform environment of hot gas flow, be heated evenly.
The utility model adopts the beneficial effect of above technical scheme to be: this coil of strip back up pad is simple and practical, execute-in-place is easily easy to maintenance, it has increased the mobility of hot gas flow by warp-wise and broadwise thermal current passway, improve phenomenon uneven in temperature in cover, thereby improved the surface quality of thermal treatment coil of strip; Moreover, by improving the roughness of Zhi Gangjuan fagging and coil of strip contact surface, can reduce coil of strip and the friction between it, thereby reduce coil of strip distortion, improve lumber recovery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be Fig. 1 along A-A to sectional view.
Fig. 3 is application schematic diagram of the present utility model.
In figure: 1 steel plate, 11 barrier bars, 12 warp-wise thermal current passways, 13 broadwise thermal current passways, 14 circular holes, 2 coil of strips, 3 inner covers, 4 tables, 5 outer covers.
Embodiment
As shown in Figure 1; the utility model is a discoidal steel plate 1; as shown in Figure 2; on steel plate 1, be provided with barrier bar 11 along even circumferential; the dead slot forming between two adjacent barrier bars 11 is warp-wise thermal current passway 12, and the width on excircle of barrier bar 11 is identical with the distance of warp-wise thermal current passway 12; In broadwise, be also provided with two broadwise thermal current passways 13; Be provided with a circular hole 14 in the centre of steel plate; As shown in Figure 3, when coil of strip 2 is placed on the utility model, cover after inner cover 3, itself and outer cover 5 form an airtight heating space; In this space, described warp-wise thermal current passway 12 and broadwise thermal current passway 13 guide to the hot gas flow being blasted from table 4 periphery of steel plate 1 equably, the hot gas flow evenly being guided converges on the top of coil of strip with the hot gas flow directly passing through through coil of strip internal diameter from described circular hole 14, thereby make coil of strip 2 be in one around in the uniform environment of hot gas flow, be heated evenly.
Above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as the technology contents essence made according to the disclosed technical scheme of this patent is identical or be equal to any change or modification, all fall into the scope that this patent comprises.
Claims (1)
