Description
Technical field
The invention belongs to steel rolling equipments to assemble field, in particular to a kind of edger roll and H-type with nested hole slot structure
The milling method of steel.
Background technique
Section Steel Production, such as the production of big H profile steel generally use X-H rolling, between omnipotent horizontal mill using edger roll come
Rolled piece edge of a wing height is controlled, due to web and edge of a wing height difference, the edger roll inner width and slot of each specification of H profile steel
Deep also different, this just determines that the edger roll pass of different H profile steels is different, and a pair of of edger roll can only be used to produce under normal conditions
A kind of H profile steel.The not high fashioned iron specification of part producing frequency, edger roll cannot use for a long time, occupy a large amount of money
Gold and storage space.
Such as application No. is 201520483121.6 patent applications to disclose a kind of H profile steel edging that can effectively reduce roller consumption
Machine matches roller pass structure.The utility model is related to a kind of H profile steel edging mill that can effectively reduce roller consumption with roller pass structure, genotype
Steel rolling equipment technical field.Its improvements are as follows: outer collars, the first abdomen on the left of including with the direction roller barrel length L sequence
Collars outside plate, edge of a wing pass groove, the second web, the edge of a wing the n-th web of pass groove ..., edge of a wing pass groove and right side, n-th
It is identical as with roller web width to distance between the (n+1)th web right side on the left of web, and match with H profile steel web height；The wing
Marginal pore type groove depth is identical as with roller depth of groove；Edge of a wing pass groove width is omnipotent first passage edge of a wing thickness ± (10-15)
mm；N-th web width is 0.8-2 times of edge of a wing pass groove depth.Match in existing edging mill and is designed on roller using nested thinking
Roll shape is nested with edge of a wing pass in pass web width range, can by edging mill with roller utilization rate improve 50%~
100%, ton steel rider consumption is reduced, there is significant economic benefit.
But two passes of the roll of above-mentioned patent application publication be it is staggered, i.e., the center line of two passes does not weigh
It closes, such arrangement is very big on the influence of the spindle of edging mill, and mobile spindle is just needed when replacing the specification of H profile steel, makes edging roller aperture
The center line of type and the center line of other horizontal rollers are obvious to the damage trend for just, thereby resulting in spindle.
Summary of the invention
The purpose of the present invention is to provide a kind of edger roll with nested hole slot structure and the milling method of H profile steel, with
Edger roll of the existing technology is solved since the single caused utilization rate of hole slot is not high and staggeredly hole slot be easy to cause spindle to damage
Bad the problems such as.
To solve the above-mentioned problems, the invention provides the following technical scheme:

Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.It should be noted that in the feelings not conflicted
Under condition, the features in the embodiments and the embodiments of the present application be can be combined with each other.
In the description of the present invention, term " longitudinal direction ", " transverse direction ", "upper", "lower", "front", "rear", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "top", "bottom", "center" is that orientation based on the figure or position are closed
System is merely for convenience of the description present invention rather than requires the present invention that must be constructed and operated in a specific orientation, therefore cannot
It is interpreted as limitation of the present invention.
In addition, term " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance
Or the quantity of technical characteristic.Be limited to " first " as a result, the feature of " second " can express or implicitly include one or
More this feature.
As shown in Figures 1 to 5, the invention discloses a kind of edger roll with nested hole slot structure, the embodiment of the present invention
The body of roll be in the form of a column, second be set to including a set of the first hole slot 1 being set on edger roll and other set on edger roll
Hole slot 2, the first hole slot 1 and the second hole slot 2 are located on same edger roll, and the second hole slot 2 is nested in the inside of the first hole slot 1,
That is specification of the specification of the second hole slot 2 less than the first hole slot 1.Specification refers to the specification of H profile steel, i.e., common 700 (height
H) * 300 (width B), 250 (height H) * 250 (width B) types of steel specification title.
The fashioned iron of first hole slot 1 of the invention and the corresponding two kinds of specifications of the second hole slot 2, two kinds of specifications can make when producing
With same a pair of of edger roll, and the steel transportation amount of each specification reach economic steel transportation amount after just carry out reparation turning so that edger roll
Accumulative steel transportation amount be much larger than common edger roll.
Further, the center line of the first hole slot 1 is overlapped with the center line of the second hole slot 2.When rolling edger roll pass with
The center line of other horizontal rollers is coped with just, since the center line of the first hole slot 1 is overlapped with the center line of the second hole slot 2, the first hole
The center line of the center line of slot 1 and the second hole slot 2 is overlapped with the center line of other horizontal rollers, so that replacement rolled section steel
Mobile spindle is not needed when specification, would not be damaged spindle yet and be effectively protected spindle, effectively increase the use of spindle
Service life.
Further, as shown in figure 4, the first hole slot 1 and second of the diameter of the end collar 3 at the both ends of edger roll and composition
The maximum gauge at the body of roll position of hole slot 2 is identical, is used with being pressed against mark zero for edger roll.Specifically, to prevent because a certain
The abrasion of pass and bring pressing mark zero distortion the case where, the present embodiment by the diameter of the end collar 3 at the both ends of edger roll with
The body of roll diameter design that works be it is identical, end collar 3 belongs to nonclient area when rolling, and diameter does not have abrasion, therefore can protect
The accuracy of card mark zero.In order to guarantee the stability in the operation of rolling, the width L1 of end collar 3 is set as the first hole slot 1 and
0.6 times or more of the groove depth H 1 of two hole slots, as shown in Figure 5.
Further, as shown in Figures 2 and 3, the first hole slot 1 is the hole slot of H profile steel；Second hole slot 2 is the hole of H profile steel
Slot.Further, the first hole slot 1 is the hole slot of big specification H profile steel 5, and the second hole slot 2 is the hole slot of small dimension H profile steel 4.Certainly,
The present invention is not limited thereto, it is contemplated that the present invention may be use with the production of other fashioned iron, such as channel steel etc..
When producing small dimension H profile steel 4 using the present embodiment, (such as Fig. 3) is produced to edger roll using this, after the completion of production again
When producing big specification H profile steel 5, still using this to edger roll (such as Fig. 2), when the steel transportation amount of two specification H profile steels all reach through
When Ji steel transportation amount, once repaired to edger roll.The use in turn of 2 two passes of the first hole slot 1 and the second hole slot, theoretically
Reach the steel transportation amount of a pair of of edger roll twice of independent pass, greatly reduces the consumption of edger roll.
The width of groove of first hole slot 1 and the second hole slot 2 is respectively set to omnipotent first passage H profile steel 5 and H profile steel 4
Edge of a wing thickness+(10-15) mm.As shown in figure 5, D2 is less than D1, setting is in order to avoid edger roll touches H in production in this way
The web of fashioned iron, and then the phenomenon that avoid the occurrence of " eating web ".
