Abstract

The invention relates to a method for arranging wrapper rollers and forming plates of a strip steel recoiling machine. The method is realized by a scrolling device which comprises a No.1 wrapper roller, a No.2 wrapper roller, a No.3 wrapper roller, a No.1 forming plate, a No.2 forming plate, a No.3 forming plate and a coiling block, wherein the coiling block is formed mainly in the manner that four coiling block fan-shaped plates and four coiling block mandrel pillars wrap a coiling block mandrel; the No.1 wrapper roller, the No.1 forming plate, the No.2 wrapper roller, the No.2 forming plate, the No.3 wrapper roller and the No.3 forming plate surround the coiling block. The arrangement method comprises the following sequential steps: I, the clearances between the No.1 wrapper roller and the coiling block in a perfect circle state, between the No.2 wrapper roller and the coiling block in a perfect circle state and between the No.3 wrapper roller and the coiling block in a perfect circle state are set to be 10mm, 8mm and 7mm, respectively; II, the clearances between the No.1 forming plate and the coiling block, between the No.2 forming plate and the coiling block and between the No.3 forming plate and the coiling block are set to be 20+/-1mm, 18+/-1mm and 17+/-1mm respectively. According to the method for arranging the wrapper rollers and the forming plates of the strip steel recoiling machine, the wrapper rollers and the forming plates have long service lives, and the qualified rate of scrolling of hot continuous rolling strip steel coiled by the recoiling machine is high.

Description

The method to set up of a kind of strip coiling machine aided winding up roller and forming board

Technical field

The present invention relates to the method to set up of a kind of strip coiling machine aided winding up roller and forming board.

Background technology

The scroll device of large-scale Hot Line coiling machine is mainly to help winding up roller and forming board, due to coil wrapper roll withforming board plays an important role to band coil of strip shape, thus must be accurately to the design of its mechanical dimension, change separately the large and precision of difficulty because these parts are on-the-spot and be difficult for ensureing, generally with help winding up roller roller arm entirety in change during repairing, its service life should be lower than 2 years.The method to set up of existing strip coiling machine aided winding up roller and forming board is unreasonable, when 1,2,3# helps that reel gap under winding up roller and round type state is respectively 10,8, when 7mm, 1,2,3# forming board and reel gap be respectively 30,28,27mm, data are bigger than normal, can not play good shaping effect to band steel; The former hot continuous rolling 2250 production line coil wrapper rolls of applicant and forming board design material are GS-20Mn5V, and wearability is poor, 1 year about 10mm of wear extent, and the coil wrapper roll of serious wear and forming board do not have good shaping effect to band steel yet.

Summary of the invention

In order to overcome the above-mentioned deficiency of method to set up of existing strip coiling machine aided winding up roller and forming board, the invention provides that a kind of hot-continuous-rolling strip steel scroll qualification rate after coiling machine batches is high, coil wrapper roll and the strip coiling machine aided winding up roller of forming board long service life and the method to set up of forming board.

The method to set up of strip coiling machine aided winding up roller of the present invention and forming board is to realize on following scroll device, scroll device comprises that 1# helps winding up roller, 2# to help winding up roller, 3# to help winding up roller, 1# forming board, 2# forming board, 3# forming board and reel, reel is mainly wrapping reel mandrel by four drum fan-shaped plates and four reel mandrel pillars and is forming, 1# helps winding up roller, 1# forming board, 2# to help winding up roller, 2# forming board, 3# to help winding up roller and 3# forming board round reel, and method to set up is following step successively:

I helps winding up roller, 2# to help winding up roller and 3# to help that reel gap under winding up roller and round type state is set to respectively 10,8,7mm 1#; II 1# forming board, 2# forming board and 3# forming board and reel gap are set to respectively 20 ± 1 mm, 18 ± 1 mm, 17 ± 1mm.

Above-mentioned strip coiling machine aided winding up roller and the method to set up of forming board, is characterized in that: described 1# forming board, 2# forming board, 3# forming board is that material is the forming board of 2Cr12NiWoMoV.

The material of forming board changes 2Cr12NiWoMoV into by GS-20Mn5V, has met the especially wear-resistant requirement of forming board shock resistance thermal deformation resistant.

The method to set up of this strip coiling machine aided winding up roller and forming board is good good in the scroll device effect of the coiling machine of western mark company of Germany 2250 Hot Line models.

Beneficial effect of the present invention

Change the method to set up coil wrapper roll of this strip coiling machine aided winding up roller and forming board and the position of forming board, and band steel finished product inner ring pine, a tower, the defect of coil shape such as loose core obviously decline, and the following thin material scroll qualification rate of 5mm improves 5 percentage points.Can reduce the loss:

2000000 tons × 5% × 300 yuan/ton=3,000 ten thousand yuan.
