Abstract
An expansion-bellows purging device comprises a main bellows and a front bellows. The main bellows is connected with the front bellows through a telescopic cylinder. An outlet end of the main bellows is connected with an upper purging beam and a lower purging beam. The upper purging beam and the lower purging beam are provided with nozzles. The expansion-bellows purging device effectively isolates emulsion and strip steel from contacting, and residue of emulsion on surfaces of the strip steel is eliminated thoroughly.
Description
Technical field
The present invention relates to a kind of telescopic bellows type blow device, be used for cold continuous rolling and single chassis reversable mill emulsion and purge.
Background technology
At present; The tandem cold rolling mill emulsion blow device all adopts the outlet multi-pass to purge the mode of beam, and this purging mode is emulsion remained with direct purging band steel plate face to be main, and blow device and purging pressure are had relatively high expectations; Emulsion still has small amount of residual, causes cold-rolled products mass defect easily.
Summary of the invention
Can not thoroughly eliminate the problem of emulsion residue in order to solve existing emulsion blow device, the present invention provides a kind of telescopic bellows type blow device, isolates emulsion effectively and contacts with the strip, and thoroughly eliminates plate face emulsion residue.
Above-mentioned purpose of the present invention is to realize through such technical scheme: a kind of telescopic bellows type blow device; Comprise the main air case; The front end bellows; The main air case is connected through telescopic cylinder with the front end bellows, and the port of export of said main air case is connected with and purges beam, purges beam down, and said going up purges beam, purges beam down and be provided with nozzle.
Be provided with track in the said main air case, the front end bellows are through the telescopic cylinder driving, along orbital motion.
The angle of said nozzle and belt steel surface is 45 °.
Be provided with water storage tank above the wind deflector of said front end bellows.
Said water storage tank both sides are provided with breach, and this breach is used for drainage.
The gap location of said main air case and front end bellows is provided with rubber sleeve.
A kind of emulsion blowing method, during steel rolling, the front end bellows stretch out near the roll gap zone, withdraw during roll change.
A kind of emulsion blowing method, front end bellows extend the roll gap zone and form zone of positive pressure, stop emulsion to flow into, and catch the emulsion that the top is wandered; Simultaneously between compressed air continues from roll gap zone, the process that upwards flows downward milling train backing roll and intermediate calender rolls, intermediate calender rolls and working roll, working roll and band steel, got rid of the emulsion current that reach downward channelling and dispel, emulsion can not drop on the plate face of being with steel.
A kind of emulsion blowing method is provided with water storage tank above the wind deflector of front end bellows, the roll band is crossed the emulsion that dispels with air-flow catch through the both sides breach and drain in the melt pit.
A kind of telescopic bellows type blow device, this device is used for the purging of rolling process emulsion.
A kind of telescopic bellows type blow device of the present invention; Be that direct purge stream is fallen the emulsion on the band steel plate face; It is main that this device contacts with belt steel surface with the isolation emulsion, utilizes flexible front end bellows and gaseous purge stream with emulsion and the isolation of band steel, thoroughly eliminates emulsion residue.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Fig. 1 is apparatus of the present invention structural representations.
Fig. 2 is apparatus of the present invention user mode reference diagram.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of telescopic bellows type blow device comprises main air case 1, front end bellows 2, and main air case 1 is connected through telescopic cylinder 4 with front end bellows 2.The port of export of main air case 1 up and down wind deflector place welds one respectively and goes up and purge beam 5 and purge beam 6 down with one, saidly goes up purging beam 5, purges beam 6 down and be provided with nozzle 8.Nozzle 8 becomes 45 ° of angles with band steel 9 surfaces.Main air case 1 inside adds weldering track 7, main air case 1 and the welding of memorial archway both sides inwall.
Main air case 1 adopts telescopic cylinder 4 to be connected with front end bellows 2, during steel rolling front end bellows 2 is driven, stretches out near the roll gap zone along track 7 through telescopic cylinder 4, can withdraw during roll change.Be provided with water storage tank 3 above the wind deflector of front end bellows 2, the roll band crossed the emulsion that dispels with air-flow catch through the both sides breach and drain in the melt pit.Main air case 1 is connected sealing with the gap location of front end bellows 2 with rubber sleeve.
The present invention adopts telescopic bellows type, and fixing one purges bellows in the outlet memorial archway, that is: the main air case 1.Respectively weld one up and down near memorial archway port of export bellows and purge beam, that is: purge beam 5 on, purge beam 6 down.Compressed air is power.Make telescopic extensible bellows at device near the roll end, that is: the front end bellows 2.
A cover telescopic cylinder 4 is installed in main air case 1 side, and compressed air is power.Front end purges and stretches out during steel rolling; To greatest extent near roll gap; Compressed air is sent to the roll gap zone and overflows about reaching up and down along roll, forms zone of positive pressure in the roll gap zone, stops emulsion to flow into; Simultaneously continue from the process that the roll gap zone upwards flows downward milling train backing roll and intermediate calender rolls 10, intermediate calender rolls 10 and working roll 11, working roll 11 and be with the emulsion current that got rid of between the steel 9 to dispel at compressed air; Emulsion upwards disperses downwards, and emulsion can not drop on the band steel 9, the almost noresidue of surfactant emulsion liquid of band steel 9.Be transformed into water storage tank 3 above the wind deflector with front end bellows 2, respectively stay a breach in water storage tank 3 both sides.The a large amount of emulsions that got rid of between the emulsion that water storage tank 3 blows up purging and intermediate calender rolls and the backing roll are caught fully, drain into memorial archway two side inflows through the both sides breach and reflux in the hole, this belt transect steel 9 in wind guide tank thoroughly with the emulsion isolation.
