The place of former inner wall smooth curved surface, thus determines that former heating surface area is extended twice or more；Also, because roller wall is made to thin-walled
State, its thickness is 5-15mm in addition to intensive deep trouth, is 1st/2nd to three of former conventional roller, thus its heat transfer time again compared with as far as
When young in two times, or speed is fast more than two times；Furthermore, because intracavitary is distributed closeer heat-collected bending resistance Beam, it has vast table
Area is absorbed heat, and can be contacted the heat to again by it on solder joint of the closeer spacing with roller inwall within 70 millimeters again
Row delivers heat to roller wall, consequently, it is possible to work on the three areas simultaneously, it will produce minimum 2 × 2 × 2=8 times of heat-transfer effect.Therefore have wide in roller
Big surface area is absorbed heat, and then heat is transmitted to the slightly lower roller table of temperature by heat transfer, during product processed because of roller table
It has been pulled away heat and has declined temperature, therefore has generated the temperature difference, (intensive deep trouth, heat-collected bending resistance Beam, annular on heat collecting
Plate) heat inhaled all can carry out transmission heat to roller table, because its heated surface area and former burnishing-in cunning inner wall surface area are relative huge,
Therefore huge lasting relatively large temperature difference heat transfer effect can be produced, roller wall is thin in addition, but because apart from it is short and accelerate heat transfer, can more produce
Raw huge and quick heat transfer effect, because heat-transfer rate is fast and sustainable, therefore can produce ultrahigh speed mode of operation.And heat-collected
Bending resistance Beam can resist the higher pressure of roller surface with annular slab.
Used when as dryer roll, roller is changed to aluminium, then cancel annular slab, heat-collected bending resistance Beam is changed to L-type, because of aluminium
Shorten three compared with steel thermal conductivity factor heat transfer time in the case of more than 100 degrees Celsius, four times, therefore, the film after gluing can be produced
High drying effect, it is adaptable to ultrahigh speed mode of operation.
If the ultrahigh speed hot-rolling is used as hot pressing steel rider, all steel are used；If being used as dryer roll, to upper
What the film after glue was dried, then using aluminium or steel.
Present invention has the advantages that：Simple in construction, production efficiency of the invention is high, and production cost is low.The thickness of roller wall of the present invention
Degree does not include intensive deep trouth, and its thickness is only two to 3 production efficiency highs of conventional roller, with the special core of hot-oil circulation isothermal hot-rolling
Axle technology is used cooperatively, and the temp effects such as roller table are up to hydrothermal circulation.Or the roller is equipped with other simple electrothermal tubes, common liquid is followed
Ring or built-in electromagnetic heating etc., after dress and axle concentric shafts, as long as high speed and superelevation effect can be obtained by meeting high power.
