Fig. 2 and Fig. 3 illustrates the roller being heated according to an embodiment of the invention and/or cool, i.e. hot-rolling 1, the thin skin 4 that this hot-rolling is provided with such as steel and the axle 2 be positioned within this skin, the surface of interior axle 2 has the chute of the runner 5 for being configured for coolant.
Hot-rolling comprises interior axle 2 and axle head 3; Axle head 3 is fastened to the end of interior axle 2, in order to bearing load.In the illustrated example shown in fig. 2, at least one axle head 3 being fastened to interior axle 2 comprises at least one runner for importing and/or derive coolant.Hot-rolling preferably includes the steel skin 4 around interior axle 2, and outer 4 for being passed to fiber web by heat from coolant during operation or being passed to coolant from fiber web.The oil that coolant preferably uses in the case of a high temperature.Coolant also can be water or steam.The runner 5 for coolant that hot-rolling comprises and interface phase between interior axle 2 and outer 3 is associatedly arranged.
Runner 5 for coolant can be made up of the chute on the outer surface 2a of interior axle 2 and the corresponding part on the inner surface of outer 4; Or be made up of the corresponding part on the skin of the chute on outer field inner surface and interior axle 2; But, also can by the surface of interior axle with on outer field surface, to align each other along the periphery direction of hot-rolling or the chute that offsets forms runner jointly.In fig. 2, runner 5 is advantageously disposed on the outer surface 2a of interior axle 2, makes between the on-stream period of hot-rolling, and these runners are formed and are preferably continuous print flow passage system in the shell area that reclines of fiber web of to be heated and/or cooling.This runner system can be made up of the runner between two ends extending in interior axle 2.Runner 5 need not with the axis being parallel of hot-rolling; On the contrary, such as, runner also can be arranged or is configured to spiral form obliquely, advantageously to avoid streak phenomenon (barring).Runner also can be set to crossing with the runner of other lateral inclinations, or crossing with the runner of other spiral form, to provide suitable turbulent flow, that is strengthens the flowing of coolant in flow passage system.
Can such as, by being suitable for bearing load, being easy to machined and the cast iron manufacture of cheapness, spheroidal graphite cast-iron, preferably GRP500 according to axle 2 in hot-rolling of the present invention.The material structure of spheroidal graphite cast-iron has homogenous properties, thus can expect and do not deposit
The distortion harmful to hot-rolling is being caused because of heat.
The skin 4 of hot-rolling also by being easy to machined and the steel making of cheapness, such as, can have the structural steel of high thermal conductivity.
Preferably, the material of outer 4 is hardened low-alloy steel.In order to make outer 4 to have expectation to the wear-resisting characteristic relevant with hardness, skin 4 is preferably hardened process, to reach that be suitable for hard conating, enough substrate hardness and stability.The obtainable hardness of structural steel is about 350HV to 400HV, and the thickness of hard material is thinner.Outer 4 can be hardened by such as flame, laser or induction hardening method.Cure process is that skin provides and is suitable for hard conating, sufficiently rigid substrate.The skin through overcure of structural steel preferably applies with metallic hard coating or carbide or ceramic coated, and this outer field case hardness is greater than 500HV in the case.Such as spraying process or laser coating method is used to apply.Preferably, when hot-rolling overall package is complete or when skin is assembled or before assembly around interior axle, can carry out machined according to coating layer thickness and coating uniformity (smoothness) to coating.
If require outer 4 to be thicker hard formation, then outer 4 can select to be manufactured by martensite steel, be preferably by stainless steel
Manufacture, namely it can reach firm case hardness without the need to independent coating, makes outer field case hardness be greater than 550HV.
The interior axle 2 of hot-rolling and the material of outer 4 easily obtain, and its manufacture needed for machine operations simple.Because hot-rolling according to the present invention has good overall thermal conductivity, use this hot-rolling can obtain high thermal power.Heat treated number of times needed for hot-rolling of the present invention is few.Interior axle 2 is without the need to heat-treating.
Surface according to the reliable near-thermal roller of the runner 5 for coolant of hot-rolling of the present invention is located, thus, make outer 4 be retained in the material between runner and thermo-roll surface on the thermal power of hot-rolling and the impact of surface temperature slight.According to the structure of hot-rolling of the present invention can easily for runner 5 provide such as there is expectation and the flow section (flowcross-section) of the size that can change on demand, position and shape.Such as, the shape of runner is made by selecting a kind of shape being suitable for machinery tools.The variable flow section of runner has variable depth easily provide by being processed into by chute, changes flow velocity thus without the need to Replacement Part (displacementpiece).Runner 5 can be optimised along the longitudinal direction of hot-rolling.Runner 5 can be easily positioned under the surface of hot-rolling, such as, be positioned the surface distance comparatively weakness from hot-rolling.Can arrange many bar runners 5 near the surface of hot-rolling, the flow section of these runners is advantageously less than the economically feasible flow section using Drilling operation technology to be formed.Such as, runner 5 by milling or such as when adopt spiral flow channel be also formed in by turning on the surface of interior axle 2.Such as, expect that the runner be arranged on outer field inner surface can correspondingly be processed by milling.The cross-sectional profiles of chute 5 preferably avoids having the shape (shape that such as interior angle is sharp-pointed and radius is very little) that possibility causes material fragmentation, divides or break.
The hot-rolling that the present invention relates to do not comprise be arranged in the axle 2 of the body forming roller, for independent " all marginal pores " of coolant flowing, or at least need not use this kind of to be enclosed in material layer and the shaft orientation flowing channel extending to the other end substantially from one end of hot-rolling housing to transmit coolant.Hot-rolling forms primarily of two parts in the region forming housing, the skin 4 of axle 2 (it can be tubulose or be mainly solid) and the relative thin-walled around interior axle 2 namely.The potential inner surface of interior axle represents with dotted line 6 in the drawings.
Hot-rolling to be regulated can be used and/or have all marginal pores hot-rolling preferably for the body of cylindrical and/or tubulose is as the matrix of axle 2 in hot-rolling according to the present invention, thus, according to the present invention, can prepare chute being formed on the outer surface 2a on this body, these chutes form a part for the cross-sectional profiles of coolant runner 5.
The skin 4 of hot-rolling can be used the mode of closing or pass through crimping (namely adopting thermal contraction method) fastened around axle 2 in hot-rolling 2, forms the connection between outer 4 and interior axle 2 thus by shrink-fit.
With regard to axle in hot-rolling 2 well connect with outer 4 by closed mode with by crimping, advantageously, interior axle 2 is in about 50 micron orders with the centrad (centricity) of skin 4, is preferably about 10 microns.In the case, interior axle 2 can not bend individually due to heat with outer 4 or bend with the form of the hot-rolling after assembling.In centrad requires, axle and the material both skin are uniformly distributed in thermal expansion situation, the thermal expansion (this uneven thermal expansion causes hot-rolling distortion by different way at different operating temperatures) that certain part in both making thus on arbitrary parts or region can not be uneven.It is also preferred that, while being heated to (or at least close) operating temperature, hot-rolling is balanced and carry out machined while heating, preferably.Two parts must carry out machined before connection.When using the screw thread as composition graphs 4 description to assemble roller, enough gap must be provided for the use of assembling.
Fig. 9 and the following description shell length provided when hot-rolling be 10 meters and the temperature of hot-rolling with 200 DEG C of changes time, calculate the example of the hot-rolling amount of deflection formed.Horizontal axis in chart shown in Fig. 9 represents the diameter of roller, and vertical axis represents the amount of deflection of roller.In this example, the pipe that the housing of hot-rolling is 180mm by wall thickness forms and has an endoporus.The steel layer that the skin of housing is 35 by thickness is formed.The material layer of the skin inside of housing is made up of spheroidal graphite cast-iron GRP.In this example, the degree of eccentricity of outer and inner material layer is selected as 10mm.
Amount of deflection as the function of the degree of eccentricity and linear change (thus when the degree of eccentricity is reduced to 1mm from 10mm, amount of deflection is reduced to 1/10th of initial value), and similarly, amount of deflection is as the function of the outer field thickness of housing and linear change (thus when the outer field thickness of housing is reduced to 17.5mm from 35mm, amount of deflection is reduced to the half of initial value).
If the amount of deflection of hot-rolling is all less than 50 microns (amount of deflection is represented by dotted lines in fig .9) under being desirably in the diameter of all practicalities, then connection surface must about the skin of roller shell and internal layer with one heart and have the machining accuracy of such as +/-0.25mm.
With chilled cast iron roller can not reach therewith closer to value.Similarly, in order to form uniform connection, connection surface must have the good cylindricity being preferably about +/-0.01mm.When being produced connection surface by turning, it is unchallenged for reaching above-mentioned cylindricity.
Fig. 4 illustrates the stereogram of hot-rolling according to an embodiment of the invention, and its ectomesoderm 4 is secured to interior axle 2 in a closed manner by screw thread 7.Hot-rolling is by screw thread 7, assembles simply by rotating skin 4 around interior axle 4.Subsequently, by mode locking screw thread 7 described below.Fig. 5 illustrates the partial sectional view along the line A-A shown in Fig. 4.Except chute 5, the outer 2a of interior axle 2 prepares external screw thread 7a, and on the inner surface of outer 4, form the internal thread 7b coordinated with external screw thread 7a.As used herein, " external screw thread " refers to the screw thread formed on the outer surface of object, and similarly, " internal thread " refers to the screw thread formed on the inner surface of object.Between hot-rolling on-stream period, the oil as coolant flows on the surface of interior axle 2, thus do not occur from the energy exchange of interior axle, and interior axle remains on the constant temperature determined by coolant.Heat exchange occurs by outer 4, and thus outer field mean temperature is, such as lower than the temperature of interior axle 2 30 DEG C to 40 DEG C.Due to the above-mentioned temperature difference, because the outer thermal expansion of interior axial ratio is more, skin 4 becomes under hot-rolling is in the condition of running, just become " being locked in " appropriate location.
