Abstract
The utility model discloses a pinch roller operating state simulating device, which is a testing device used for simulating the operating state of the pinch roller between a tail rack of continuously rolling with cold and a tension rolling cylinder. The utility model is provided with a machine frame, guide rollers and a tension roller. The two guide rollers and one tension roller are arranged on the machine frame in a triangular position. The pinch roller composed of one pressing roller and one driving roller is arranged on the position corresponding to the tension roller and is arranged between the two guide rollers on the machine frame. At least one guide roller of the two guide rollers is the driving roller. The device can simulate the nodulation and the friction scratch and other conditions of the roller surface of the pinch roller under the conditions of different band steel speeds, tension degrees, speed differences and pinching degrees.
Description
The utility model relates to a kind of pinch roll Work condition analogue device, is a kind of experimental rig that is used to imitate the duty of the pinch roll between cold continuous rolling tailstock and the tension reel.
Pinch roll is operated between cold-rolling mill tailstock and the tension reel, its effect is blocked but before not entering second tension reel as yet and rebuliding tension force at the band steel, clamping and drive band steel by two rollers about it run up, and keep the forward pull of tailstock band steel.Because pinch roll is bearing and the not exclusively synchronous caused friction and the band steel is nipped and impact during whipping of band steel, roll surface is very easy to scratch and also produces the dross phenomenon, and then causes belt steel surface to scratch and defectives such as surperficial pitting point.For addressing this problem, many enterprises are all spraying the modification processing to the pinch roll surface.But since rolling band steel kind different with specification, working conditions such as the clamping degree of strip speed and tension force and pinch roll alter a great deal, be difficult to determine desirable sprayed on material and spraying coating process, therefore need set up a corresponding analogue means, so that under different working conditions, carry out a large amount of simulated tests, by estimating roll surface coating performance index, filter out best sprayed on material and spraying coating process.In the prior art, steel transmission simulator in a kind of high speed stabilized zone is disclosed in the first volume first phase in " plasma spray technology " February nineteen ninety-five " application of plasma spray technology in the steel and iron industry " literary composition, form by two guide rollers and two jockey pulleys, one is that one of live-roller is driven voller in two guide rollers, and two jockey pulleys are driven voller.Two guide rollers are in the bilateral symmetry setting, and two jockey pulleys are symmetrical arranged up and down.During test, the speed of tension force and live-roller by the adjustment of tonicity roller, the abrasion condition between simulation different steel speed and tension force condition lower roll surface and the band steel.But because this simulator is not provided with clamp mechanism, can't simulate the fretting wear situation that can reflect when pinch roll has relative slip at clamping band steel and with the band steel, therefore can't be with this as the foundation of estimating roll surface coating performance index and screening best sprayed on material and spraying coating process.
The purpose of this utility model provides a kind ofly can simulate different steel speed, tensile force, the speed difference when clamps the friction scratch of degree condition bottom pinch roll and the pinch roll Work condition analogue device of dross production, for pinch roll sprayed on material and the corresponding spraying coating process of selecting to optimize provides effective research technique.
The purpose of this utility model realizes by following technical solution.
A kind of pinch roll Work condition analogue device has frame, guide roller and jockey pulley, and two guide rollers and a jockey pulley three position triangular in shape are provided with and are installed on the frame.A pair of by a hold-down roller and the pinch roll that live-roller constitutes, be installed on the frame position relative between two guide rollers with jockey pulley; At least one is a live-roller in two guide rollers.
Be equipped with one on the frame in order to measure the velometer of band steel wire speed.
Guide roller, jockey pulley and pinch roll all adopt the cantilever beam design and installation on frame.
All be coated with the rubber roll surface on guide roller and the jockey pulley.
Two rollers that constitute pinch roll all adopt structure of mosaic.
The advantage that the utility model is compared with prior art had is: one of two jockey pulleys of the prior art are changed into a pair of pinch roll with transmission agency, make the utility model pinch roll Work condition analogue device very convenient simulation to adopt the pinch roll of various face coats in different steel speed, tensile force, under the conditions such as speed difference clamping degree when, roller, relatively slide between the band friction scratch that produced and the situations such as generation of dross are for pinch roll sprayed on material and the corresponding spraying coating process of selecting to optimize provides succinct effectively research technique.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of the utility model pinch roll Work condition analogue device.
The utility model pinch roll Work condition analogue device, as shown in the figure, mainly pinch roll and the jockey pulley 6 that constitutes by frame 1, guide roller 2 and velometer 3, by a hold-down roller 4 and live-roller 5 formed.Two guide rollers 2 are live-roller and are arranged on the frame both sides, and a jockey pulley 6 is arranged on below between two guide rollers 2, and three position triangular in shape is provided with and is installed on the frame.All be coated with the rubber roll surface on guide roller 2 and the jockey pulley 6,, reduce the disturbing factor of simulated test to avoid relative slip with steel band and scratch steel strip surface.By a hold-down roller 4 and the pinch roll that live-roller 5 constitutes, be installed on the frame 1 jockey pulley 6 tops between two guide rollers 2.The hold-down roller 4 and the live-roller 5 that constitute pinch roll all adopt structure of mosaic, so that the loading and unloading during spray test, and save testing expenses.Guide roller 2, jockey pulley 6 and constitute the hold-down roller 4 of pinch roll and live-roller 5 all is to adopt the cantilever beam design and installation on frame 1 are so that the installation of steel band 7.A velometer 3 is installed on the frame 1, and the detection head and the steel band of velometer 3 are vertically opposite, in order to measure the linear velocity of band steel.
When adopting pinch roll after different sprayed on material and the spraying coating process spray treatment to test, start the live-roller 5 of guide roller 2 and pinch roll, regulate the clamping force of pinch roll and the tension force of jockey pulley 6.Because the rotating speed of each live-roller and clamping force and tensile force all are continuously adjustable, and the rotating speed of each roller can be by detecting with the coaxial mounted encoder of roller, the tensile force of the clamping force of pinch roll and jockey pulley 6 can detect by pressure sensor, and measure the linear velocity of band steel by velometer 3, therefore, this device can simulate different steel band speed, tensile force, speed difference than and situations such as the friction scratch of condition bottom pinch rolls such as clamping force and dross tendency, can provide effective foundation for pinch roll sprayed on material and the corresponding spraying coating process of selecting to optimize.
