Abstract
The invention relates to a rolling method capable of preventing steel ingot rolling tilting. The method comprises the steps that (1) a steel ingot is rolled to a previous pass of a pass which is not smooth, namely when the length of the steel ingot is smaller than or equal to 5100 mm, steel ingot tilting is removed through a smooth pass; (2) when the steel ingot is larger than 5100 mm, under manual swinging and pressing, pressing amount of each pass is 15 mm-25 mm, through the longitudinal held angles of +/- (5-15 degrees) of the wide-rotating steel ingot, a head is meshed in, and under manual lifting and pressing at a next pass, treading air-through operation is used; and (3) under manual swinging and pressing, the head is meshed in, pressing amount at each pass is head single-pass meshing-in amount, and treading air-through returning is carried out until the smooth pass is over. The rolling method has the advantages treading single-pass oblique rolling is used, dead head tilting caused by dead head meshing in can be effectively avoided, accordingly, steel ingot head tilting during rolling can be lowered, the risk of water box collision is prevented, and when the steel ingot head falls down, the risk of roller way flapping is avoided.
Description
Technical field
The milling method that steel ingot rolling is upwarped is solved the present invention relates to a kind of.
Background technology
During military project steel ingot is produced, due to Steel ingot feeder head, there is the situation that rolling is upwarped, upwarped for this at present
Treating method for increase planishing pass, i.e., width is smooth after carrying out turning steel to steel ingot, but is less than for target thickness
The steel ingot of 250mm, cannot when upwarping because its length is more than 5100mm (5500 rolling line roughing mill breast roll length are 5030mm)
Carry out it is smooth, to complete military project steel ingot rolling there is greater risk, while when rising head is nipped occur pat breast roll roller-way, this
Sample causes certain harm to equipment.
The content of the invention
To overcome the deficiencies in the prior art, the rolling side that steel ingot rolling is upwarped is solved it is an object of the invention to provide a kind of
There is ingot head and upwarps in rolling in method, reduction, prevents steel ingot from patting roller-way.
To achieve the above object, the present invention is achieved through the following technical solutions：
It is a kind of to solve the milling method that steel ingot rolling is upwarped, comprise the following steps：
1) when steel ingot is rolled down to upper a time for being unsatisfactory for planishing pass, i.e. steel ingot length≤5100mm, by smooth road
Secondary elimination steel ingot is upwarped；
2) as steel ingot length ＞ 5100mm, pendulum pressure manually, draught per pass is 15~25mm, and is made by width rotation
Steel ingot longitudinally holds the angle of ± (5 °~15 °), and head is nipped, and lower a time is lifted pressure and steps on sky mistake using pin manually；
3) pendulum pressure manually is continued, head is nipped, every time band drafts is all that head single track is nipped, and pin is stepped on empty mistake and returned
Return, until planishing pass terminates.
Compared with prior art, the beneficial effects of the invention are as follows：
The oblique rolling of single pass is stepped on using pin, can effectively be evaded and cause rising head because rising head is nipped and upwarp, so can be with
There is ingot head and upwarps in rolling in reduction, prevents from clashing into the risk of water box；When ingot head falls, prevent from patting roller-way
Risk.
Brief description of the drawings
Fig. 1 is the operating diagram of the embodiment of the present invention.
Specific embodiment
The present invention is described in detail with reference to Figure of description, it should be noted that implementation of the invention is not limited
In following implementation method.
It is a kind of to solve the milling method that steel ingot rolling is upwarped, comprise the following steps：
1) steel ingot is rolled down to the upper a time for being unsatisfactory for planishing pass, i.e. steel ingot length≤5100mm (or ingot thickness
＞ 250mm) when, steel ingot is eliminated by planishing pass and is upwarped；
2) as steel ingot length ＞ 5100mm, pendulum pressure manually, draught per pass is 15~25mm, and by width rotation steel
Ingot longitudinally holds the angle of ± α, and head is nipped, and lower a time is lifted pressure and steps on sky mistake using pin manually；
3) pendulum pressure manually is continued, head is nipped, every time band drafts is all that head single track is nipped, and pin is stepped on empty mistake and returned
Return, until planishing pass terminates.
Hold angle [alpha]=5 °~15 ° in described longitudinal direction.
Embodiment：
See Fig. 1, pin steps on the oblique rolling of single pass：Steel ingot is rolled down to and is unsatisfactory for the upper a time i.e. thickness of planishing pass and is more than
During 250mm, just eliminating steel ingot frequently with planishing pass and upwarping；As steel ingot length ＞ 5100mm, then using pendulum pressure manually,
Every time 15~25mm drafts, while the angle for allowing steel ingot longitudinally to hold ± 5~15 ° by rotation wide, it is desirable to which head is (non-to emit
Mouthful) nip, lower lift pressure steps on sky mistake using pin manually together, then proceedes to put pressure manually and allows head to nip, that is, ensure per pass
Sub-band drafts is all that head single track is nipped, and pin is stepped on empty mistake and returned, and so can effectively evade steel ingot and upwarp problem, and then ensure
Steel ingot is successfully rolled.
The present invention steps on the oblique rolling of single pass using pin, can effectively evade and cause rising head because rising head is nipped and upwarp, this
Sample can be reduced to be there is ingot head and upwarps in rolling, prevents from clashing into the risk of water box；When ingot head falls, prevent from patting
The risk of roller-way.
Claims (1)
1. it is a kind of to solve the milling method that steel ingot rolling is upwarped, it is characterised in that to comprise the following steps：
1) when steel ingot is rolled down to upper a time for being unsatisfactory for planishing pass, i.e. steel ingot length≤5100mm, disappeared by planishing pass
Except steel ingot is upwarped；
2) as steel ingot length ＞ 5100mm, pendulum pressure manually, draught per pass is 15~25mm, and makes steel ingot by width rotation
The angle of ± (5 °~15 °) is held in longitudinal direction, and head is nipped, and lower a time is lifted pressure and steps on sky mistake using pin manually；
3) pendulum pressure manually is continued, head is nipped, every time band drafts is all that head single track is nipped, and pin is stepped on empty mistake and returned, directly
Terminate to planishing pass.
