Description of drawings
Fig. 1 is the structural representation of a kind of taper roller-way of providing of the utility model embodiment;
Wherein, symbol description among the figure:
1 bearing block, 2 bearings, 3 rollers, 4 taper sheaths,
41 weld grooves, 42 roll shafts, L bus.
The specific embodiment
During crimp oblique milling groove rolling H shaped steel, common 8 °～24 ° of rolling each passage pass technology gradient.Wherein, common 20 °～24 ° of K1 passage pass technology gradient, common 15 °～21 ° of K2 passage pass technology gradient, common 12 °～18 ° of K3 passage pass technology gradient, common 12 °～18 ° of K4 passage pass technology gradient, common 8 °～13 ° of K5 passage pass technology gradient.When this just requires the rolled piece steel billet to enter each passage crimp oblique milling groove rolling, must form inclination angle more than 8 ° with roller 3 center lines, it is rolling to nip smoothly.Therefore, for the ease of each the passage crimp oblique milling groove rolling of nipping smoothly of rolled piece steel billet, need make the rolled piece steel billet form 8 °～10 ° inclination angle at roller 3 taper sheath 4 that is welded.
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Referring to Fig. 1, the utility model embodiment provides a kind of taper roller-way that is arranged on the roughing mill front and back, and this taper roller-way comprises: bearing block 1, bearing 2, roller 3 and taper sheath 4; Bearing 2 is arranged in the bearing block 1, the two ends of roller 3 are installed in respectively in the bearing 2, in order to make the rolled piece steel billet milling train of nipping smoothly, thereby reduce axial force and the impact load of the roll in rolling, the roller 3 between bearing 3 is welded with one or more taper sheath 4.
For taper sheath 4 is removed and installed easily, be provided with weld groove 41 at the endoporus of taper sheath 4 along the two ends of short transverse, when using, by weld groove 41 taper sheath 4 is welded on the roller 3.Such taper sheath, if through using for a long time, taper sheath 4 can produce wearing and tearing, the taper sheath 4 after the wearing and tearing can not be beneficial to the rolled piece steel billet roughing mill of nipping again, needs to install new taper sheath for this reason.For new taper sheath is installed, can separate with roller 3 by the existing metal cutting techniques taper sheath 4 of experience wear, weld new taper sheath after the polishing more again.As the metal cutting techniques, preferably utilize the gas cutting technology.
In order to make taper sheath 4 and roller 3 have good welding performance, the material of taper sheath 4 can be preferably carbon cast steel for carbon cast steel or low-alloy wear-resistant steel.
In order to make the rolled piece steel billet milling train of nipping smoothly, be 8 °～10 ° on that limit (the axial limit of endoporus) of the axially contact roller 3 of roller 3 with the L shaped angle theta that becomes of the bus of taper sheath (in fact just the L shaped angle that becomes of the axial and bus of taper sheath of roller 3) in taper sheath 4 endoporus, be preferably 8 °.In use, owing to be welded with taper sheath 4 on the roller 3, the axial limit of the endoporus of this taper sheath 4 and bus be L shaped to become certain included angle, make the rolled piece steel billet carried at roller 3 be rolled with certain inclination angle milling train of nipping smoothly, further reduced rolling in axial force and the impact load of roll.
According to rolling pass pass technological requirement, can a plurality of taper sheaths 4 be installed at the roller 3 between bearing 2, the angle θ of a plurality of taper sheaths 4 can be identical, also can be different.
When the angle of a plurality of taper sheaths is different, can satisfy the inclination angle requirement that multiple rolled piece steel billet is nipped, but in the reality, the angle θ of taper sheath 4 gets identical value usually, unification is got by lower limit.
In order to satisfy in the be welded requirement of a plurality of taper sheaths 4 of roller, need the height of taper sheath 4 be limited, height (the distance from the top margin to the base of general taper sheath, the also i.e. height of figure axis direction) the maximum specification bottom width with the rolled piece steel billet adapts, usually the big 30mm of maximum specification bottom width than rolled piece steel billet gets final product, the maximum specification bottom width of this example rolled piece steel billet is 200mm, and then the height of taper sheath is preferably 230mm.
In application, the diameter of bore of the taper sheath 4 of a plurality of taper roller-ways is generally than the big 2mm～3mm of diameter of roller 3, so that run through on the roller 3, and require to be weldingly fixed on the taper sheath 4 according to rolling pass.
Certainly, the shape of taper sheath 4 can that is to say the angle of taper sheath according to being convenient to the high temperature billet steel rolling variation of deriving of nipping smoothly, and height can change according to different operating positions with length.
In order to make the simple and economical high efficiency of processing, according to the rolling pass requirement, taper sheath 4 runs through and is weldingly fixed on the roller 3.Preferably the quantity of the taper sheath 4 that is welded at roller 3 is two, two taper sheaths 4 do not connect, be welded on to keep at a certain distance away on the roller 3, the base of any in two taper sheaths 4 is near roll shaft 42 1 sides, this roll shaft 42 is connected with transmission device, and transmission device rotates by roll shaft 42 drive roller 3.The number of degrees of the number of degrees of the angle that the axial limit of endoporus of a taper sheath in two taper sheaths and bus form and the axial limit of endoporus of another taper sheath and the angle of bus formation can be identical, also can differences, and present embodiment does not limit this.
Have good lubricated service behaviour between bearing block 1 and the bearing 2 in order to make, bearing block 1 is provided with the grease lubricating system (not shown).
Be welded with taper sheath on the roller 3, in application, the type of pair of rollers does not limit, and roller can be solid roll, can also be hollow roller, can also be the other types roller.
The roller of taper sheath of being welded can be installed in the front and back of roughing mill as roller-way, also can only be installed in a side of milling train as required, in addition, also can not roughing mill but the milling train of other types, such as straightener, when the aligning shape steel rolled stock, also needing rolled piece to form certain inclination angle could align, and this just needs the taper sheath that is welded on the straightener approach table.
The taper roller-way that present embodiment provides, by being welded with taper sheath at roller, satisfied the roughing mill rolling pass technology inclination angle requirement of adopting the crimp oblique roll process, being convenient to high temperature billet steel nips rolling smoothly, thereby reduce axial force and the impact load of rolling middle roll, and making is processed simply, is removed and installed easily remarkable in economical benefits.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
