Abstract
The invention provides a roll cooling method for rolling of composite metal, for solving the problem that the composite effect of two types of metal is easy to be affected in the process of cooling rolls by emulsion or rolling oil. Blind-hole channels are arranged on an upper roll and a lower roll of a rolling mill along the center axes of the rolls; cooling water pipes with outside diameter smaller than inside diameter of the blind-hole channels are disposed in the blind-hole channels; cooling pressure water is delivered into the cooling water pipes, flows out of the tail ends, at the bottoms of blind-hole channels, of the cooling water pipes, and returns to areas between the outer walls of the cooling water pipes and the inner walls of the blind-hole channels so as to dissipate heat of the rolls. The invention further provides a special cooling device. Through holes are formed in bearing end caps at the ends of inlets of the blind-hole channels arranged along the center axes of the rolls, rotary joints are respectively connected with water inlet pipelines, the through holes and return pipelines, the cooling water pipes are mounted in axial channels formed by the blind-hole channels, the through holes and the rotary joints which are communicated in sequence, and the inside diameter D1 of the blind-hole channels, the aperture D2 of the through holes and the aperture D3 of the rotary joints are all larger than the outside diameter d1 of the cooling water pipes.
Description
Technical field
The present invention relates to composite material process unit field, be specially a kind of roll cooling means and cooling device for composite material rolling.
Background technology
Conventionally in the common sheet material operation of rolling, all need to adopt a large amount of emulsions or ROLLING OIL to carry out cooling roll, control strip shape, if but when producing composite material rolling, still by emulsion or ROLLING OIL, come cooling roll, control strip shape can have a strong impact on two kinds of metal material composite effects, cause composite material qualification rate low.
Summary of the invention
For the problems referred to above, the invention provides a kind of roll cooling means for composite material rolling, it can solve and adopt existing emulsion or ROLLING OIL to come cooling roll easily to affect the problem of the composite effect of two kinds of metals; For this reason, the present invention also provides Special cooling device.
Roll cooling means for composite material rolling, it is characterized in that: on the upper and lower roll of milling train, along roll central axis, offer blind hole passage respectively, and the cooling water pipe that external diameter is less than described blind hole passage internal diameter is set in described blind hole passage, in cooling water pipe, pass into cooling pressure water, thereby cooling pressure water is from cooling water pipe, the end in described blind hole channel bottom flows out and refluxes and take away roll heat from the region between cooling water pipe outer wall and blind hole vias inner walls.
It is further characterized in that:
Described cooling pressure water water temperature≤30 ℃;
The flow of described cooling pressure water is 6.0 m
3/ h～7.0m
3/ h;
The hydraulic pressure of described cooling pressure water is controlled by water supply pump, and the operating pressure of described water supply pump is 0.5 Mpa～0.55Mpa.
Special roller cooling device for composite material rolling, it comprises be arranged in parallel upper, lower two rolls, described roll two ends are installed on bearing block by bearing respectively, it is characterized in that: it comprises cooling water pipe, swivel joint, inlet pipeline and water return pipeline, the external water supply pump of described inlet pipeline, described roll has blind hole passage along central axial direction, the bearing (ball) cover of one end, corresponding described blind hole feeder connection place has the through hole coaxial with described blind hole passage, the axial two-port of described swivel joint connects respectively described inlet pipeline and described through hole, the vertical port of described rotatable interface connects described water return pipeline, described cooling water pipe is installed on by described blind hole passage, through hole, the axial passage of swivel joint successively UNICOM forms in an axial passage, the inner diameter D 1 of described blind hole passage, the aperture D2 of through hole and the axial passage inner diameter D 3 in swivel joint are all greater than the outside diameter d 1 of described cooling water pipe.

Roll cooling means for composite material rolling of the present invention, it is to carry out cooling from core of the roll breaker roll, thereby the problem that affects metal material composite effect of effectively avoiding the cooling means because adopting a large amount of emulsions or ROLLING OIL to infiltrate roll outer surface to bring, therefore it can improve metal material composite effect; During due to composite material rolling, its linear velocity speed lower, that produce heat is slower, and water temperature, pressure, the flow of therefore controlling cooling pressure water can reach the cooling requirement of breaker roll, its good cooling results.Roll cooling device for composite material rolling provided by the invention, its simple in structure, simple operation.
Accompanying drawing explanation
Fig. 1 the present invention is for the structural representation of the roll cooling device of composite material rolling.
The specific embodiment
Roll cooling means for composite material rolling, it offers blind hole passage along roll central axis respectively on the upper and lower roll of milling train, and the cooling water pipe that external diameter is less than blind hole passage internal diameter is set in blind hole passage, in cooling water pipe, pass into cooling pressure water, thereby cooling pressure water is from cooling water pipe, the end in described blind hole channel bottom flows out and refluxes and take away roll heat, interim cooling pressure water water temperature≤30 ℃ from the region between cooling water pipe outer wall and blind hole vias inner walls; The flow of cooling pressure water is 6.0 m
3/ h～7.0m
3/ h; The hydraulic pressure of cooling pressure water is controlled by water supply pump, and the operating pressure of water supply pump is 0.5 Mpa～0.55Mpa.
See Fig. 1, roll cooling device for composite material rolling, it comprises be arranged in parallel upper, lower two rolls 1, roll 1 two ends are installed on bearing block 3 by bearing 2 respectively, it also comprises cooling water pipe 4, swivel joint 5, inlet pipeline 6 and water return pipeline 7, roll 1 has blind hole passage 8 along central axial direction, the bearing (ball) cover 9 of corresponding blind hole passage 8 one end, porch has the through hole 10 coaxial with blind hole passage 8, the entrance point of swivel joint 5 is connected with through hole 10, cooling water pipe 4 is installed in blind hole passage 8 and its inlet end stretches out through through hole 10, the rear connection inlet pipeline 6 of swivel joint 5, the port of export of swivel joint 5 connects water return pipeline 7, the aperture D1 of blind hole passage 8, the aperture D2 of through hole and the axial passage inner diameter D 3 in swivel joint are all greater than the outside diameter d of described cooling water pipe.Aperture 45mm≤D1≤the 50mm of blind hole passage; External diameter 32mm≤d1≤the 28mm of cooling water pipe, the internal diameter 25mm≤d2≤20mm of cooling water pipe.In Fig. 1,11 is oil sealing.During this cooling device work, cooling pressure water by inlet pipeline 6 input cooling water pipes 4, from cooling water pipe 4, at the cooling water pipe end of blind hole channel bottom, flow out, enter again that cooling water pipe 4 refluxes with the region between blind hole passage 8 inwalls and from rotation, connect the vertical port inflow water return pipeline 7 of 5, thereby realize the cooling of breaker roll.
