Description
Technical field
The present invention relates to a kind of online roll continuous constant temperature heating temperature-control system, belong to roll heating temperature control technology field.
Background technology
For metal material, when using cold rolling, due to the mechanical property of metal in itself, in rolling reduction
Greatly, during the sheet material of thickness of thin, the unstable quality problems of many occur after rolling；And despite first heating rolled piece, then
Rolled on roll, be Strip for some rolled pieces without heated roll because simply being heated to rolled piece, especially thickness
The poor rolled piece of thin and plasticity, because the temperature difference of roll and rolled piece make it that the cooling velocity of rolled piece is very fast, causes rolled piece rolling
Plasticity is decreased obviously in journey, and resistance of deformation gradually increases, then occur in the operation of rolling side split or crackle expansion, and then
Rolled piece is scrapped.
With the development of science and technology, the method for online hot rolling can be divided into four kinds of methods at present, and first method is most former
The method of beginning, first to roll surface heating, is heated to after proper temperature remove heater, is then rolled again, still
The method, it is impossible to realization on-line heating in the operation of rolling to roll, and thermostatic control can not be realized to roller surface temperature.The
Two kinds of methods, using electrical heating, to heat roller core, such as Chinese Patent Application No. 201310518804.6（A kind of on-line continuous is rolled
Roller heater and its processing method）With 201510015783.5（Differential temperature and isothermal roll heater and milling method）With
201220520261.2（A kind of electrical heating roll）Etc. utility model device, although can realize that on-line continuous is heated, because
In roll open interior, heated to install electrically heated rod, long-term heating can make to produce oxide skin on heating rod, obstruct the effect of heating
Really, in addition heating rod rotation fracture generation, also, use electrically heated rod heated roll, firing rate is slow and temperature of heating
Degree is not easily controlled, in addition, electrically heated rod is heated, the temperature of the roll surface of roll differs greatly during heating, and to the roller of roll
Body produces the influence of certain rigidity or intensity, and using electrical heating, the requirement for insulation protection is higher, to operator's
Personal safety also has certain danger.The third method, uses sensing heating roller surface, roll is distributed in by using induction coil
Both sides, to roll surface heating.Such as China Patent No. 03206018.1（A kind of roll repair welding electromagnetic induction heater）、
201510022238.9（Magnesium alloy board roll induction heating method and device）、201510541230.3（One kind is used for rolling
The device and method that roller is heated）、201220017184.9（Heating coil for Electromagnetic Heating hot roll）With
201620785046.3（Double roll electromagnetic heaters）Etc. utility model device, using these new roll heaters,
Although the purpose of on-line continuous heating can be reached, in the operation of rolling electromagnetic induction to the temperature of roll surface heating not
It is good, thermostatic control is difficult to realize, and when rolling is that rolled piece roll banding occur, occurs upwarping or have a downwarp easily to rush at and heat dress
Put, be damaged heater, and the induction heating apparatus handling of roll are all relatively difficult.4th kind of method, is rolled with conduction oil
Roller surface is heated, i.e. the perforate on the roller core of roll, and the conduction oil of injection heating is to roll surface heating.Such as China Patent No.
201210066580.5（Heated roll）、201410048249.X（A kind of roll sleeve type roll of use heat-conducting oil heating）、
201020164251.0（Heat conducting oil heating roller）、201520021175.0（Various temperature pattern roll heating dress can be achieved
Put）、201521041738.9（Heated roll）With 201620949873.1（A kind of roll with heating function）Deng practical new
Type device, although can meet the continuous on-line heating to roll, but have because the aperture space opened inside roll is larger,
Weaken the rigidity and intensity of roll itself, have because the complex-shaped of internal openings does not allow easy processing, difficulty of processing is big, into
This height, have due to heating oil duct from roller surface with a distance from far and skewness, cause the efficiency of heating surface to roller surface slow
It is uneven with heating.
The content of the invention
The present invention is to provide for a kind of continuous, online and constant temperature roll heating temperature control device, it is intended to make up prior art

26.5% biphenyl and 73.5% Biphenyl Ether are constituted, and the heating temperature range of conduction oil is：12 °~400 °.
Due to using above-mentioned technical proposal, the present invention has the advantage that compared with prior art：
One is that hollow roll and the solid roll shaft of spiral of two perforate are used cooperatively, when hollow roll use time is permanent
Afterwards, if there is roll surface wearing, hollow roll can be changed at any time, without again to roll overall processing；Two be to use spiral
Solid roll shaft, is machined with spiral oil duct to allow conduction oil to circulate on the solid roll shaft of spiral, because spiral oil duct is solid in spiral
Distribution on roll is relatively uniform, so that when conduction oil flows through spiral oil duct, the heating to hollow roll is also just relative
Uniformly so that the heating-up temperature of roller surface is with regard to that can be uniformly distributed, as long as because continuing constant temperature fuel feeding in spiral oil duct, so that just
It can guarantee that the temperature of roller surface is continuously constant, be conducive to the steady quality of rolled piece in the operation of rolling；Three be that temperature control system passes through
The first temperature sensor is controlled continuously to measure the temperature of roller surface, by the first temperature sensor feedback to temperature control
System adjusts the heating-up temperature of heating system, and then adjusts by second temperature sensor the oil temperature of conduction oil, the company of realization
Continue online thermostatic control；Four be spiral oil duct due to itself frictional resistance to conduction oil, slow down the flow velocity of conduction oil, extends
Residence time of the conduction oil in helical cavity, heat is fully used, and improves the utilization ratio of the energy.
