Description

Aluminium strip six-high cluster mill strip surface blow device

Technical field:

The utility model relates to the aluminium strip rolling mill technical field, a kind of aluminium strip six-high cluster mill strip surface blow device.

Background technology:

In existing four roller aluminium strip rolling mills, the plate top blast that installs behind the machine is swept mechanism and has been taked the roll gap blockade, roll surface purges, and the plate top blast on the band is swept, and lower face purges and means such as upper face secondary purging are removed coiled material residual ROLLING OIL of upper and lower plate face after rolling.By these measures, solved the problem of taking away ROLLING OIL basically, but still had some rolling Residual oils.

Summary of the invention:

In order to solve the problem of above-mentioned existence, the utility model provides a kind of aluminium strip six-high cluster mill strip surface blow device, the space in its milling train exit can be arranged original parts of blow device very easily, so that make the effect of removing board rolling oil more satisfactory, can fundamentally solve the problem that ROLLING OIL is removed from strip surface.

The utility model is to adopt following technical scheme to solve:

Described aluminium strip six-high cluster mill strip surface blow device, this blow device is positioned at the six-high cluster mill exit, its splash-back is installed on the guide rail of roll line top in milling train exit, guide rail is fixed on the memorial archway, protective plate is fixed on the memorial archway in milling train exit, the below of splash-back, delivery guide is installed on the guide rail of roll line below in milling train exit, guide rail is with fixing on the memorial archway, the roll surface blowing mechanism is installed in above the splash-back, the upper face blowing mechanism is installed in the below of splash-back, the roll gap blocked mechanical system is installed in splash-back and delivery guide front end, and the lower face blowing mechanism is installed on the delivery guide, and the secondary blowing mechanism is installed on the protective plate.

Described aluminium strip six-high cluster mill strip surface blow device, the centre of the roll surface blowing mechanism of this blow device is equipped with big flow nozzle, and both sides are furnished with the low discharge nozzle; On the secondary blowing mechanism of installing on the protective plate big flow nozzle is installed, both sides are furnished with the low discharge nozzle; Front guide two ends at the band lower face at the roll gap blocked mechanical system place of delivery guide front end are provided with two sections purge nozzle.

Owing to adopted technique scheme, the utility model to obtain following good effect:

In the former purging system, one group of nozzle the blockade of roll gap outside the roll of contact band being taked to be positioned on the splash-back of band upper face purges the dynamics deficiency.And the utility model has newly designed two sections purge nozzle at the front guide two ends of band lower face, to strengthen its effect.These two sections new type nozzles that are called as " gas cutting cutter " can be continuous, block roll gap outside the band on a large scale.

According to the flowing law of ROLLING OIL behind the machine, oil stream mainly concentrates on the core of working roll and backing roll.In order to strengthen purging to the centre ROLLING OIL, newly to design a kind of big flow nozzle and be installed in the centre, all the other positions dispose the low discharge nozzle of right quantity again, make it to cooperatively interact, and plate face Residual oil are purged clean.

In the purge of upper face, the form that has also adopted big flow nozzle to add the low discharge nozzle purges effect to strengthen it.

By the exploration of long period, grasped the flowing law of ROLLING OIL behind the machine, found past some defective in the design purging system, can suit the remedy to the case, further improvement has been done in design, fundamentally solve the problem that ROLLING OIL is removed from strip surface.

Description of drawings:

Fig. 1 is the structural representation of aluminium strip six-high cluster mill strip surface blow device.

Among the figure: 1-splash-back, 2-protective plate, 3-delivery guide, 4-roll surface blowing mechanism, 5-upper face blowing mechanism, 6-roll gap blocked mechanical system, 7-lower face blowing mechanism, 8-secondary blowing mechanism, the big flow nozzle of 9-, the big flow nozzle of 10-.

The specific embodiment:

As shown in fig. 1, this blow device installs after belonging to the six-high cluster mill machine, its splash-back (1) is installed in the roll line top in milling train exit, can move up and down with the guide rail on memorial archway along it, be convenient to roll change, its effect is to block the ROLLING OIL of splashing from entrance side in process of production, with prevent it splash down the outlet strip surface, also having an effect is to block four ROLLING OIL of penetrating of splashing when the machine post-purge, allows it flow away from the splash-back both sides; Protective plate (2) is fixed on the memorial archway in milling train exit, is in the below of splash-back (1), and its main effect is the head of protection calibrator, prevents when broken belt or magnetic tape trailer breaks calibrator after leaving roll; Delivery guide (3) is positioned at the below of the roll line in milling train exit, can move up and down along its guide rail that is fixed on the memorial archway, is convenient to roll change, and its purposes is that the band head that guiding is shut out by roll gap moves on along this guide plate, falls and curling round the roll to prevent band; Roll surface blowing mechanism (4) is installed above the splash-back (1), splash-back (1) below is equipped with upper face blowing mechanism (5), splash-back (1) and delivery guide (3) front end are equipped with roll gap blocked mechanical system (6), lower face blowing mechanism (7) is installed on the delivery guide (3), secondary blowing mechanism (8) is installed on the protective plate (2).

The front guide two ends of the band lower face of locating at the roll gap blocked mechanical system (6) of delivery guide (3) front end are provided with two sections purge nozzle.

Centre at working roll and backing roll, in order to strengthen purging to the centre ROLLING OIL, in the centre of roll surface blowing mechanism (4) a kind of big flow nozzle (9) is installed, all the other positions dispose the low discharge nozzle of right quantity again, make it to cooperatively interact.

In order thoroughly to remove the ROLLING OIL of band upper surface, go up in the secondary blowing mechanism (8) of dress at protective plate (2), the form that has also adopted big flow nozzle (10) to add the low discharge nozzle purges effect to strengthen it.

When band from milling train exit output when delivery guide (3) advances, compressed air enters roll surface blowing mechanism (4) by pipeline, purging by big flow nozzle (9) and low discharge nozzle will accumulate in ROLLING OIL between top backing up roll and the top working roll and dispel and be unlikely to drop to strip surface, compressed air enters upper face blowing mechanism (5) by pipeline simultaneously, can remove ROLLING OIL attached to upper face, compressed air enters lower face blowing mechanism (7) by pipeline simultaneously, can remove ROLLING OIL attached to lower face, compressed air enters roll gap blocked mechanical system (6) by pipeline, on two groups of nozzle alignments of design, the bottom working roll roll gap purges, and sprays the ROLLING OIL of coming to stop from entrance side; Compressed air enters the purging of secondary blowing mechanism (8) by big flow nozzle (9) and low discharge nozzle by pipeline, and the ROLLING OIL that does not have thoroughly to remove in once purging is removed once more.
