Abstract
The utility model relates to a buffered inlet guide device which comprises a bottom plate, two side plates and two pairs of guide wheels, wherein, the two side plates are symmetrically fixed on the both sides of the bottom plate; each side plate comprises an inlet lining plate and a wear-resistant lining plate, wherein, a corner is formed at the connecting point between the inlet lining plate and the wear-resistant lining plate, one pair of the guide wheels is symmetrically installed at the connecting point between the inlet lining plate and the wear-resistant lining plate, and the other guide wheels is symmetrically installed on the wear-resistant lining plate; and the buffered inlet guide device further comprises buffering devices installed on the side plates and respectively arranged corresponding to the guide wheel axles of the guide wheels. The utility model changes the original rigid contact between the side part of the band steel and the surfaces of the guide wheels, and has larger width automatic regulation capability. When the deviation of the band steel is larger, the pressure change between the side part of the band steel and the surfaces of the guide wheels can be adjusted and reduced. Therefore, not only can the frication between the side surface of the band steel and the surface of the side plate of the inlet guide plate be reduced, but also the phenomenon of steel clamping caused by pressure jump or sharp increase at the side part of the band steel and the surfaces of the side plates can be avoided.
Description
Technical field
The utility model relates to steel rolling inlet guide and guards, particularly a kind of inlet guide and guards with buffering.
Background technology
In the steel rolling industry, all rolling machinery overwhelming majority have guide device at the entrance side of milling train, are commonly called as " entrance guide plate ".Fig. 1 is the schematic diagram of existing inlet guide device, Fig. 2 be among Fig. 1 the inlet guide device A-A to cutaway view.As depicted in figs. 1 and 2, existing inlet guide device comprises a base plate 1a and two side plate 2a, and two side plate 2a symmetries are fixed on the both sides of base plate 1a, and described base plate 1a is vertical welding or bolt connection structure with side plate 2a.Each side plate 2a is made of the inlet liner plate 21a of pilot tape steel 3a direction of advance and the abrasion-proof backing block 22a of control strip width respectively, and there is corner the junction of inlet liner plate 21a and abrasion-proof backing block 22a.Rolling band steel 1a needs the inlet guide device to lead before entering working roll 4a and being rolled, and band steel 3a runs on the base plate 1a of inlet guide device, and is subjected to the guiding of the side plate 2a of both sides, to prevent the steel plate sideslip.Because hot-strip is in the process of wearing band continuously, the limit portion of band steel rubs with the side of entrance guide plate continuously mutually through regular meeting, has caused the rapid wearing and tearing of impaired and guide plate side liner plate of the limit portion of band steel.
1, surface of side plate easily produces the metal knurl.On continuous hot-rolling mill, because the temperature of band steel higher (generally greater than about 900 degree) has heat radiation again to liner plate, the temperature of liner plate body is more than 150 degree, and this phenomenon is just more obvious.Because technical requirement, the material of liner plate body generally adopts the lower steel of hardness ratio (as SS40), its objective is that the limit portion for the boundary belt steel is not subjected to too big damage.But the thing followed is the wearing and tearing aggravation of liner plate, and the replacement cycle of liner plate is very short, generally can only be controlled at 1-2 week, determines the different replacement cycles according to the difference of rolling kind, but has more uncertainty in actual the maintenance.And suitable irregular of the polishing scratch on the liner plate caused the limit portion of band steel easily and draws trace and burr.But the band steel is in the process guide plate, because all milling trains all have the sideslip of trace at present, the limit portion of band steel one side always be unable to do without the guide plate liner plate, contact with the bolt connecting portion easily, like this at the head of bolt, gathered rapidly that strip edge portion rubs mutually with the guide plate liner plate and the metal knurl that produces, in the process of continuous rolling, it is long-pending more big more, finally dropping is pressed into the surface of band steel on the surface of being with steel, thereby forms depression at belt steel surface, causes product quality problem in batches, the frequency of occurrences of this phenomenon is quite high, and is especially obvious in rolling slab and high-temperature steel.According to the long observation at scene, cause the burr with the limit portion of steel, body that to draw main three main causes of defectives such as trace, depression in the surface be liner plate progressively the exposing of the high liner plate body wear aggravation that causes of temperature and uncertain, liner plate positioning bolt hole and bolt, strip edge portion rubs mutually with the guide plate liner plate and the metal knurl problem that produces.
2, artificial reconditioning need be frequently carried out in the surface of side plate wearing and tearing.Because hot-strip 3a is in the process of wearing band continuously; the limit portion of band steel 3a rubs with the side plate 2a of inlet guide device continuously mutually through regular meeting; the rapid wearing and tearing of impaired and side plate 2a of the limit portion of band steel 3a have been caused; the replacement cycle of side plate 2a is very short; generally can only be controlled at for 1～2 week; difference according to rolling kind is determined the different replacement cycles, but has more uncertainty in actual the maintenance.And suitable irregular of the polishing scratch on the side plate 2a caused the limit portion of band steel 3a easily and draws trace and burr.Thereby cause product quality problem in batches, the frequency of occurrences of this phenomenon is quite high.
Easy steel scrap when 3, the strip running deviation amount is big.Someone has developed a kind of entrance guide plate with guide wheel; because guide wheel can be followed the motion of rolling middle band steel; replace the speed of related movement of guide plate surface of side plate and rolled band steel to reduce greatly with guide pulley surface; effectively slow down the friction of band steel side and entrance guide plate surface of side plate; need not often to utilize roll change or downtime that the surface of side plate of entrance guide plate serious wear is carried out artificial reconditioning, higher labour intensity and danger when having avoided entrance guide plate to safeguard.But in actual applications, when the strip running deviation amount is big, pressure between strip edge portion and guide pulley surface steel running deviation value going along with increases and sharply increase (both proportional relations), the inlet guide and guards of existing anti-band steel frictionally damage then seems at a loss what to do to this, tend to assembly steel-fastening herein and cause the steel scrap fault, cause 2 steel billets that leave heating furnace to become intermediate blank simultaneously, the steel billet wasting of resources is bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of inlet guide and guards with buffering, changes that original rigidity contacts between strip edge portion and the guide pulley surface, has bigger width self-regulation ability.When the strip running deviation amount is big, pressure variation between strip edge portion and the guide pulley surface can be regulated and reduce to the inlet guide and guards of band buffering, and the friction that not only slows down band steel side and entrance guide plate surface of side plate, can also effectively avoid the pressure jump of strip edge portion and surface of side plate or sharply increase and the steel-fastening that causes.
