Abstract
The invention discloses a double-pass roller for machining track shape steel and a rolling method. The two passes of the double-pass roller are formed by rolling grooves in an upper roller and rolling grooves in a lower roller are symmetrical about an axis AA and are communicated with each other, and the axis AA is perpendicular to the horizontal center line BB of the two passes. According to the rolling method, the track shape steel is rolled on a production line which is formed by a roughing mill unit and a finish mill unit, and the finish mills of the finish mill unit are provided with double-pass rollers for machining the track shape steel. When the track shape steel is rolled through the double-pass rollers, rolling speed, namely steel yield per hour, is increased, production cost is reduced, rolling stability is improved, and the rate of finished products is increased.
Description
Technical field
The present invention relates to the rolling field of deformed steel in the rolling of sectional iron, be specifically related to a kind of track shoes roll diapsid and milling method, is a kind of brand-new pass exploitation and milling method, and it improves deformed steel hour output of steel and rolling stability, reduces production costs.
Background technology
Track shoes is mainly for the manufacture of bull-dozer, tractor caterpillar, that typical special-shaped difficulty is rolled kind, because the asymmetry of section, metal differs greatly in the distribution of section each several part, it is serious that reflection shows as the inhomogeneous deformation of operation of rolling steel in process of production, it is large to roll rear steel cooling flexibility, thereby causes the profile of product and dimensional accuracy to be difficult to guarantee that the production development difficulty is large.
For present steel production enterprise, the crawler belt steel is that it has one of product of high benefit.General track shoes mainly adopts following production line to produce, and comprises roughing unit and mm finishing mill unit, and it is back and forth rolling that the roughing unit by R1 roughing → crop → R2 roughing carries out cogging to steel billet; Rolled piece enters mm finishing mill unit subsequently, carries out the single pass formation rolling between U1-U2-U3; With carrying out crop, segmentation by hot saw, cold saw carries out collecting warehouse-in after the scale sawing.The roll pass of producing the finishing mill of track shoes is single track shoes pass, low and the single track shoes pass of track shoes hour output of steel causes rolling stability poor, yield rate is low, only be 80%, wilderness demand that can't satisfying the market, therefore need to improve production line with raising hour output of steel, and improve rolling stability, increase yield rate.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of track shoes roll diapsid is provided.This diapsid can improve the i.e. hour output of steel of mill speed, reduces production costs.
Another object of the present invention is to provide a kind of method that adopts the rolling track shoes of above-mentioned roll diapsid, this milling method can improve rolling stability, improves yield rate.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of track shoes roll diapsid is formed by the top roll of finishing mill and the groove of lower roll, this diapsid be a pair of along axis AA track shoes pass symmetrical and that be communicated with through join domain.Described axis AA is vertical with the horizontal center line BB of described diapsid.
Because the roll pass of existing finishing mill is single track shoes pass, track shoes hour output of steel is low, so the present invention is on the basis of existing equipment, by reference existing " crawler belt " Pass parameter, adopt symmetrical turning, to go out along axis AA symmetry be a pair of track shoes pass of left-right symmetry and connection in turning on new roll.Output of steel can be doubled in such hour.
In described track shoes roll diapsid, as a kind of preferred embodiment, the length of described join domain is 250-280mm, highly is 80-85mm, is convenient to like this secondary machine.More preferably, the length of described join domain is 250mm, highly is 80mm.
In described track shoes roll diapsid, described join domain can be communicated with a pair of track shoes pass in any position of vertical direction, that is to say, described join domain can be positioned at described diapsid horizontal center line BB top, below or cover the horizontal center line BB of described diapsid, as a kind of preferred embodiment, the horizontal center line BB of described diapsid passes through described join domain central point, and intersects in described central spot and described axis AA.That is to say that described join domain covers the horizontal center line BB of described diapsid just.
In described track shoes roll diapsid, as a kind of preferred embodiment, described join domain links together part corresponding with the free end of the non-guided plate of rolling track shoes in the described a pair of track shoes pass.
A kind of milling method of track shoes, it is rolled by the production line that roughing unit and mm finishing mill unit consist of, each finishing mill in the described mm finishing mill unit has the roll (being designated hereinafter simply as symmetrical pass) of above-mentioned track shoes diapsid, and this milling method comprises following operating procedure:
Step 1, it is rolling to utilize the roughing unit that blank is carried out R1 roughing → crop → R2 roughing, enters the required rolled piece of mm finishing mill unit to roll out;
Step 2 utilizes the U1-E1-U2-E2-U3 milling train that described rolled piece is carried out a pair of track shoes (be symmetrical pass mill product) of finish rolling to obtain connecting as one successively;
For the roughing mill in the roughing unit is adapted with the finishing mill with above-mentioned roll pass, the roll of roughing mill also needs symmetrical turning pass, namely according to existing size turning left-right symmetry pass on new roll, in order to roll out the required rolled piece of mm finishing mill unit.
Because the finishing mill that uses in this milling method has the roll that above-mentioned pass is symmetrical pass, compare with the single-orifice type milling method, overcome because of deformed steel rolling in, stress is asymmetric, the asymmetric rolled piece that causes of shape twists, the problem of size distortion, the rolled piece that causes because roll-force is inhomogeneous is head and nose phenomenon partially, overcome simultaneously the unsettled problem of transporting that rolled piece causes because profile is asymmetric when roller transport, the rolling rolled piece that improves of diapsid is at the rolling stability in tandem mill zone simultaneously.
The present invention compared with prior art has following beneficial effect:
The present invention is according to section steel works Minifab rolling mill design ability, on the basis of existing equipment, designed diapsid (being symmetrical pass), the method that adopts symmetrical pass to be rolled, improved mill speed, original production line hour output of steel is 35-40t, and hour output of steel is 75-80t behind the roll diapsid of the present invention and adopt; And because symmetrical configuration, rolling stability is improved, and yield rate has increased 10-12%, makes the rolling mass production of accomplishing maximum-norm of track shoes, has reduced production cost.
Description of drawings
Fig. 1 is the symmetrical pass mill product cross sectional view that adopts symmetrical pass roll of the present invention to be rolled;
Fig. 2 is the schematic diagram of the symmetry rolling pass (being diapsid) that forms of the groove of milling train top and bottom rolls of the present invention.
Wherein, description of reference numerals is as follows: 1-1# tooth, 2-2# tooth, 3-3# tooth, the non-guided plate of 4-, 5-guided plate
The specific embodiment
