Description
Technical field: the utility model relates to a kind of steel plate on-line insulating device, particularly a kind of rolling line stay-warm case.
Background technology: at present, steel rolling mill exports the rear end at roughing mill, and to the flying shear inlet, operated by rotary motion has a plurality of stay-warm cases, puts down during use; Lift when not using.Purpose is to reduce the temperature loss of intermediate blank, is convenient to the rolling of finishing mill.In actual production, this have certain insulation effect, and still, heat insulation effect is bad, and the temperature difference in the cross section of intermediate blank is very big, because the existence of the big temperature difference (about 50 ℃), directly influenced the Functionality, quality and appealing design yield of sheet material finished product; As: thickness and precision, temperature accuracy, template precision etc.Secondly, because the insufficient height of stay-warm case is damaged by the band steel of nose bump often, influenced normal use.In order to improve heat insulation effect, the electromagnetic induction of employing strip edge heater is also arranged, but this installation cost is very high, power consumption is very high, annual electric consumption cost is about 500～6,000,000 yuan, and because heating wire is arranged on two sides of stay-warm case, makes that the heating of steel plate is inhomogeneous, cause steel plate uneven in temperature, influence follow-up finish rolling.
Summary of the invention: the purpose of this utility model provides a kind of temperature loss can reduce the on-line rolling of slab before heating furnace is retracted to finishing mill the time, guaranteeing that normally nipping of finishing mill is the stability in the operation of rolling, thereby improve the rolling line stay-warm case of the end product quality of coiled sheet.The technical issues that need to address are: reduce the slab temperature drop in the rolling process of rough rolling, the uniformity that improves board briquette and the minimizing slab bump accident to cover cap.The technical solution of the utility model is: the rolling line stay-warm case, bracket basis is fixed with fixed support, fixed support connects swing arm by rotating connecting shaft, on the swing arm by the fixing stay-warm case of anchoring piece, stay-warm case is provided with thermal insulation layer and heat-insulation layer, the stay-warm case below is fixed with bearing block on the basis, roller-way is installed on the bearing block, roller-way one end is provided with deflector apron, it is characterized in that: stay-warm case is arranged side by side vacuum extractor with being connected of swing arm in the cross section, gas combustion apparatus and ignition, described vacuum extractor is by the air pipe arrangement, stop valve, connect flexible pipe, control valve and nozzle constitute, the air pipe arrangement connects stop valve, stop valve connects control valve, and the air pipe arrangement connects by connecting flexible pipe in the corner, and nozzle one end connects the air pipe arrangement other end and penetrates stay-warm case.Gas combustion apparatus is made of combustion gas pipe arrangement, stop valve, connection flexible pipe and nozzle, and the combustion gas pipe arrangement connects stop valve, and the combustion gas pipe arrangement connects by connecting flexible pipe in the corner, and nozzle one end connects the combustion gas pipe arrangement other end and penetrates stay-warm case.Combustion gas pipe arrangement and air pipe arrangement are two king's fonts in the framework of stay-warm case upper surface arranges, is vertically arranging a plurality of gas nozzles on the straight line, and laterally straight line evenly is furnished with air and gas nozzle.
The beneficial effects of the utility model are: reduce rolling temperature drop, can guarantee the stability of stinging steel state and logical plate of finish rolling better.Save the heating furnace burnup; Temperature loss when having reduced on-line rolling under the prerequisite of temperature is nipped in equal finish rolling, can suitably reduce the heating-up temperature of heating furnace.Improve the end product quality of slab.Because the inside and outside temperature homogeneity of slab has obtained good improvement, makes that the drag of slab in the operation of rolling is more aligned, be very helpful to improving plate shape.Increase rolling milimeter number, the production capacity of more effective performance rolling line, input, use, maintenance cost reduce significantly.
