Roll system

Technical field

The utility model relates to a kind of roll system.

background technology

In common Rolling Production, adopt the fountain type of cooling to carry out cooling roll, cooling medium has emulsion or the full oil of water, content 5%.

And the micro oil " dry lubrication " that the cold composite roll of two kinds of metals adopts is almost " dry lubrication " roll carried out under fully without the situation of cooling medium;

Due to the particularity of metal composite rolling, the fully inapplicable type of cooling during with the metal composite rolling of fountain cooling and lubricating mode, so general hollow working roll water flowing or the blower fan breaker roll of adopting of its type of cooling blows cooling.

Hollow working roll water flowing is due to the restriction that is subject to roll strength, and hollow diameter can not be enough large, and the water flowing underfed is to play the effect that continues the cooling work roller;

The blower fan quenching, due to the restriction that is subject to environment temperature, can not be enough to effectively continue the temperature rise of chill roll system;

Therefore, the temperature that two kinds of above-mentioned types of cooling all can not fully continuously and effectively solve roll constantly raises and makes roll production convexity problem, particularly spring and summer, summer, summer and autumn roller system temperature rise coolingly seem particularly important.

In sum, how designing a kind of roller that can solve effectively constantly in the metal composite operation of rolling is the new process for cooling device that temperature rise causes the hot convexity problem of roll production, becomes those skilled in the art's matter of utmost importance urgently to be resolved hurrily.

Please refer to Fig. 1 and Fig. 2, wherein, Fig. 1 is the structural representation of roll system in a kind of embodiment of the utility model; Fig. 2 is along the cutaway view of A-A in Fig. 1.

The utility model provides a kind of roll system, include two backing rolls and two working rolls, backing roll and working roll are enumerated setting according to the order of backing roll, working roll, working roll, backing roll, backing roll rolls and contacts with working roll, be formed with the rolling gap of passing through for composition metal between two working rolls, also include: the first cooling package, the first cooling package includes for the cooling tube of cooling medium circulation and the EGR be communicated with cooling tube, cooling tube and the backing roll rotating contact that is positioned at upside; The second cooling package, the second cooling package includes cooling water tank and circulation piping, and the circulation piping is communicated with cooling water tank, is provided with cooling medium in cooling water tank, and the backing roll that is arranged in downside is invaded and is steeped in cooling medium.

The roll system that the utility model provides, in working order under, working roll contacts with composition metal, the fricative heat of working roll and composition metal makes the working roll temperature raise; Working roll rolls and contacts with backing roll, and backing roll is undertaken cooling by the first cooling package and the second cooling package, and the backing roll of low temperature contacts with working roll, thereby reaches the purpose to the working roll effective temperature-reducing.

Particularly, it is roundabout or be parallel to backing roll and axially be arranged side by side and form the cooling tube group that cooling tube is the s type, the arcuate structure of cooling tube group for matching with backing roll.

It is the process for cooling technical field that the utility model relates to the composition metal Rolling roller, and in the utility model, roller system is by the cooling lower backing roll of water tank, and the conduction bottom working roll is cooling, controls the hot convexity of bottom working roll; Be provided with cooling tube (cooling jacket) on the backing roll of the utility model device upside, coolant jacket is arranged the cooling tube conduction upper backup roll heat of rotation, cooling upper backup roll, and upper backup roll conduction top working roll is cooling, controls the hot convexity of top working roll.

After the operation of the utility model device, realize that roller is that temperature is effectively controlled, reach and promote two kinds of metal composite band production efficiencys.

For the roller that solves constantly in the composite rolling process is temperature rise, the utility model provides a kind of direct-cooled backing roll conduction working roll cooling new equipment.

The bottom working roll cooling principle: lower backing roll is immersed in water, and the water that heat is flowed by water tank is taken away, cooled lower backing roll contact bottom working roll, and the heat of bottom working roll is walked in conduction band, and the temperature that the bottom working roll rotation is produced is lowered;

Water after the heat exchange of flowing out through water tank is again used as new water circulation after cooling tower is cooling.

The top working roll cooling principle: top working roll carries out heat exchange with arrangement and rotatable cooling tube wall in coolant jacket after contacting, the heat of its contact-making surface tube wall that is cooled is taken away, cooled upper backup roll contact top working roll, the heat of top working roll is walked in conduction band, and top working roll is lowered because of the temperature that the rolling rotation produces;

Cooling medium contact tube wall in cooling tube absorbs heat, and mobile cooling medium is continuously taken away the heat of tube wall, realizes the exchange heat of upper backup roll and temperature is reduced;

The heat exchange medium flowed out through cooling tube is by after cooling processing, and the cooling tube of again inputting coolant jacket recycles.

The utility model comprises:

Be arranged on the cooling water tank of lower backing roll below, new water successively enters water tank through oral siphon, and the heat of the lower backing roll of rotation is flowed into the water exchange disconnectedly and lower the temperature in water tank;

Lower backing roll rotates a circle, and the water in water tank completes a heat exchange;

When bottom working roll contacts again with lower backing roll, the heat of lower backing roll is exchanged by the water of water tank, the stack of empty calory;

While contacting with bottom working roll by the lower backing roll of lowering the temperature, heat can be replaced by lower backing roll again, and the bottom working roll temperature is reduced;

When bottom working roll contacts with the metal rolled material of roll entrance again, the synergistic effect of bottom working roll empty calory;

So go round and begin again, the lower backing roll heat by water cooling after the conduction to bottom working roll, bottom working roll is lowered the temperature.
