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, purge for cold continuous rolling and single chassis reversable mill emulsion.
Background technology
At present, tandem cold rolling mill emulsion blow device all adopts outlet multi-pass to purge the mode of beam, and this Purge methods is with steel plate surface emulsion remained directly to purge, to blow device and to purge pressure requirements higher, emulsion still has a small amount of residual, easily causes cold-rolled products mass defect.
Summary of the invention
Thoroughly can not eliminate the problem of emulsion residue in order to solve existing coolant emulsion liquid blowing remover, the invention provides a kind of telescopic bellows type blow device, effectively isolate emulsion and contact with the strip, thoroughly eliminate plate face emulsion residue.
Above-mentioned purpose of the present invention is realized by such technical scheme: a kind of telescopic bellows type blow device, comprise main air case, front end bellows, main air case is connected by telescopic cylinder with front end bellows, the port of export of described main air case is connected with purging beam, lower purging beam, and described upper purging beam, lower purging beam are provided with nozzle.
Be provided with track in described main air case, front end bellows are driven, along orbital motion by telescopic cylinder.
The angle of described nozzle and belt steel surface is 45 °.
Water storage tank is provided with above the wind deflector of described front end bellows.
Described water storage tank both sides are provided with breach, and this breach is used for drainage.
The gap location of described main air case and front end bellows is provided with rubber sleeve.
A kind of emulsion blowing method, during steel rolling, front end bellows stretch out close to roll gap region, retract during roll change.
A kind of emulsion blowing method, front end bellows extend roll gap region and form zone of positive pressure, stop emulsion to flow into, and catch the emulsion wandered top; Simultaneously to continue from roll gap region, the process that upwards flows downward Mill and intermediate calender rolls, intermediate calender rolls and working roll at compressed air, to get rid of between working roll and band steel and the emulsion current of channelling downwards dispel, emulsion can not drop on the plate face of band steel.
A kind of emulsion blowing method, is provided with water storage tank above the wind deflector of front end bellows, roll band is crossed the emulsion dispelled with air-flow and catches and drained in melt pit by both sides breach.
A kind of telescopic bellows type blow device, this device is used for the purging of emulsion in rolling process.
A kind of telescopic bellows type blow device of the present invention, it is the emulsion that direct purge stream falls on band steel plate surface, this device contacts with belt steel surface to isolate emulsion, utilizes flexible front end bellows and purges air-flow by emulsion and the isolation of band steel, thoroughly eliminate emulsion residue.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is apparatus of the present invention structural representations.
Fig. 2 is apparatus of the present invention using state reference diagram.
Detailed description of the invention
As shown in Figure 1 and 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 by telescopic cylinder 4 with front end bellows 2.The upper and lower wind deflector place of the port of export of main air case 1 weld respectively one upper purge beam 5 and one under purge beam 6, described upper purging beam 5, lower purging beam 6 are provided with nozzle 8.Nozzle 8 and the surperficial angle at 45 ° of band steel 9.Main air case 1 inside is welded with track 7, and main air case 1 welds with memorial archway both sides inwall.
Main air case 1 and front end bellows 2 adopt telescopic cylinder 4 to be connected, and driven by front end bellows 2, stretch out close to roll gap region along track 7, can retract during roll change during steel rolling by telescopic cylinder 4.Be provided with water storage tank 3 above the wind deflector of front end bellows 2, roll band crossed the emulsion dispelled with air-flow and catch and drained in melt pit by both sides breach.The gap location of main air case 1 and front end bellows 2 is connected with rubber sleeve and seals.
The present invention adopts telescopic bellows type, purges bellows, that is: main air case 1 at outlet memorial archway internal fixtion one.Respectively weld one up and down near memorial archway port of export bellows and purge beam, that is: above purge beam 5, lower purging beam 6.Compressed air is power.Telescopic extensible bellows, that is: front end bellows 2 are made near roll end at device.
A set of telescopic cylinder 4 is installed in main air case 1 side, and compressed air is power.During steel rolling, front end purges and stretches out, to greatest extent close to roll gap, compressed air be sent to roll gap region along roll up and down and left and right overflow, zone of positive pressure is formed in roll gap region, emulsion is stoped to flow into, simultaneously continue the process upwards flowed downward from roll gap region, Mill and intermediate calender rolls 10, intermediate calender rolls 10 and working roll 11, the emulsion current that got rid of between working roll 11 and band steel 9 to be dispelled at compressed air, emulsion upwards disperses downwards, emulsion can not drop on band steel 9, the surfactant emulsion liquid almost noresidue of band steel 9.Be transformed into water storage tank 3 by above the wind deflector of front end bellows 2, respectively stay a breach in water storage tank 3 both sides.Water storage tank 3 will purge the emulsion that blows up and a large amount of emulsions of getting rid of between intermediate calender rolls and backing roll are caught completely, drains in memorial archway two side inflow backflow hole by both sides breach, this belt transect steel 9 in wind guide tank thoroughly and emulsion isolate.
