Description
Technical field:
The utility model relates to a kind of roll primary heater unit, belongs to field of mechanical technique.
Background technology:
Metallic substance is in the cold conditions operation of rolling, and owing to rolled band steel thickness is thin, distortion amount is big, and the belt steel temperature after rolling can reach 120-150 DEG C, and therefore the temperature of roll is very crucial to the stability in the operation of rolling and quality control. in general cold continuous rolling production process, inevitably carry out roll change. it is directly load frame at normal temperatures due to new roller so that newly there is obvious temperature head (about 50-60 DEG C) between roller and old roller. meanwhile, owing to band steel is thin so that when new roller is started shooting after loading again, plate shape is difficult to control, and this kind of situation is the most outstanding in last frame. during in order to alleviate cold continuous rolling roll change, temperature head between new roller and old roller, have developed roll primary heater unit, existing roll primary heater unit is all generally be wound with multiple heater strip on the surface of roll, heated to roll by heater strip, this kind of pre-thermal means only can make the surface of roll reach preheating temperature, and the internal temperature of roll is still lower, thus make the surface of roll and inner formation temperature poor, namely there is certain roll thermal crown in roll, for above-mentioned reasons, although this kind of roll primary heater unit can alleviate the low problem of roller surface temperature a little, but in actual use, fail to reach ideal effect, so industry needs a kind of can the roll device of inside and outside preheating, to solve the problem run in industry.
Summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of roll primary heater unit, to solve problems faced in current industry.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of roll primary heater unit, is provided with the roller core in column structure, and the outer sheath of described roller core is connected to roller shell.
As preferably, the center of described roller core is provided with the Transverse Heated hole in horizontal structure.
As preferably, described Transverse Heated hole, through the rear and front end of described roller core, described roller core is also provided with multiple erecting to heating hole.
As preferably, described erecting extends through described Transverse Heated hole to heating hole from the surface of described roller core.
As preferably, described Transverse Heated hole is respectively arranged with multiple heating rod with erecting in heating hole.
As preferably, described to erect the quantity to heating hole be 48.
As preferably, the arranged outside in described Transverse Heated hole has temperature-detecting device.
As preferably, described temperature-detecting device being provided with Temperature displaying table, described temperature-detecting device is also provided with warning device.
As preferably, the material of described roller core is 32Cr3MolV.
Compared with prior art, usefulness of the present utility model is: be provided with roller core, outer sheath at roller core is connected to roller shell, in described roller core, it is provided with Transverse Heated hole and erects to heating hole, in heating hole, it is provided with heating rod with erecting in described transverse direction, by carrying out preheating to heating rod heats to whole roller core, the front end in Transverse Heated hole is provided with temperature-detecting device, it is thus possible to the Heating temperature of detection roller core, and adjust temperature in time. The utility model structure is simple, and easy to operate, cost is lower.
