Abstract
The utility model provides a continuous casting flame-cutting cinder flushing chute having a dustpan-shaped structure, wherein chute edges are respectively arranged on the front side, the rear side and one lateral surface of the rectangular cinder flushing chute; the other lateral surface of the rectangular cinder flushing chute is opened; at least two spraying holes on which duck bill-shaped high-pressure water spray nozzles are formed on the chute edge of the lateral surface of the rectangular cinder flushing chute; and a slope of 2-5 degrees is formed between the chute bottom and a horizontal plane. By adopting a mode of flushing away molten cinder from the opened end with the slope through one-step flushing, the molten cinder falling into the cinder flushing chute during flame cutting can be completely flushed by high-pressure water without any accumulated cinder, thereby avoiding the manual cleaning, saving the cost expenditure and reducing the maintenance workload and the labor intensity, wherein the cost for each chute each year can be saved by one hundred thousand Yuan.
Description
Technical field
The utility model belongs to the smelting servicing unit, relates in particular to the cinder-flushing groove that prevents accumulated slag in a kind of continuous casting flame cutting strand process.
Background technology
In continuous casting production process, need hot base is carried out flame cutting,, therefore below slag, be installed on a special cinder-flushing groove, be used for collecting slag and slag poured in the sluice with water under high pressure owing in the process of cutting, can produce a large amount of slags.Cinder-flushing groove is a rectangular open trough of being made up of bottom land and four sides ledge, and the backing plate below bottom land is connected on the base.Have spray-hole on the ledge of two sides of cinder-flushing groove, sharp mouth form height setting-out nozzle is installed in the spray-hole.Simultaneously, also be provided with a scum hole at the center of bottom land.The slag that is collected in the cinder-flushing groove flows in the sluice via the bottom land scum hole under the washing away of both sides water under high pressure.But the flushing cinder mode that this both sides water under high pressure liquidates, slag tap in the centre is difficult to the slag in the cinder-flushing groove is rinsed fully, very easily form accumulated slag at bottom land, need to adopt and manually regularly the accumulated slag of cinder-flushing groove is cleared up, average per 10 days will be to the casting machine cleaning once, each cleaning all need spend about about 3000 yuan of fund, and cinder-flushing groove be mounted in fiery cutter below, change and maintenance very difficult, not only time-consuming but also effort.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple, is convenient to operation, can prevent accumulated slag, improves the flushing cinder effect and the continuous casting fire in service life and cuts cinder-flushing groove.Its concrete scheme is:
A kind of continuous casting fire is cut cinder-flushing groove, comprises bottom land, ledge and backing plate, and described cinder-flushing groove is " dustpan " shape structure, and forward and backward of the rectangle cinder-flushing groove and a side are provided with ledge, and another side is uncovered, has at least 2 spray-holes on the ledge of side.
The end that bottom land has ledge is higher than opening end, forms 2 °～5 ° the gradient between bottom land and the horizontal plane.
The duckbill nozzle is installed in the described spray-hole.
The thick corrosion resistant plate welding processing of the described cinder-flushing groove employing 8～12mm of system forms.
The beneficial effects of the utility model are:
Owing to adopt a series of effective measures such as a side blow water, band gradient bottom land and duckbill nozzle, the slag of falling in the cinder-flushing groove when making the flame cutting can be washed away totally by water under high pressure fully, not residual any accumulated slag, thereby need not to carry out the labor cleaning, saved the expense expenditure, reduced maintenance load and labour intensity, each groove can be saved 100,000 yuan of value every year.And simple in structure, be convenient to implement small investment, instant effect.
Description of drawings
Accompanying drawing is cut the cinder-flushing groove schematic perspective view for the continuous casting fire.
Among the figure: spray-hole 1, ledge 2, bottom land 3, backing plate 4.
The specific embodiment
Cut the cinder-flushing groove stereogram as seen by the continuous casting fire, the utility model is made of ledge 2, bottom land and backing plate 4.Whole cinder-flushing groove is one " dustpan " shape, and bottom land 3 is a rectangular flat plate, is welded with the ledge of opening outside the top 2 respectively at front, back and the left surface of bottom land 3, and right flank is not established ledge 2 and is designed to uncovered only.Have 4 spray-holes 1 on the ledge 2 in left side, in each spray-hole 1 the duckbill hydraulic spray is installed all, it is long-pending that the duckbill nozzle can obviously increase the high pressure water jets surface sweeping, avoided injection " dead angle ".
Below bottom land 3, be provided with the supporting backing plate 4 of a size and dimension and bottom land 3, cinder-flushing groove be connected on the base by backing plate 4.Wash away for being easy to slag, so pass through in the mode of bottom land 3 with the left end shimming of backing plate 4, the left end that makes bottom land 3 promptly is provided with a little higher than opening end of an end of ledge 2 and spray-hole 1 a little more than right-hand member, make bottom land 3 have certain slope, form 3 ° angle between bottom land 3 and the horizontal plane.
The ledge 2 of the cinder-flushing groove of the utility model and bottom land 3 all adopt the thick corrosion resistant plate welding processing of 10mm to form, and both can improve the corrosion-resistant property of cinder-flushing groove, can strengthen the resistance to deformation intensity of cinder-flushing groove again.
