Abstract
The utility model relates to a cooling water adjustment device for preventing the roller surface from scaling, which comprises a water cutting plate arranged the outer peripheral side of a working roller, a scaling-preventing water header pipe support located below the water cutting plate and a scaling-preventing water header pipe arranged on the scaling-preventing water header pipe support and used for preventing an oxide film on the roller surface of the working roller from scaling, wherein a locating bearing pedestal (5) used for rotating the scaling-preventing water header pipe (4) is arranged on the water cutting plate (2) of the cooling water adjustment device, the scaling-preventing water header pipe (4) can rotate around the locating bearing pedestal (5) as a rotating fulcrum when the roller diameter varies in order to ensure that cooling water sprayed from the scaling-preventing water header pipe can always cool band steel at the inlet of the roller, and scaling-preventing water can not be sprayed to the roller because the positions of a guide and guard device and the water cutting plate vary after the roller diameter varies.
Description
Technical field
The utility model relates to the steel rolling automation field, and particularly, the utility model relates to a kind of cooling water adjusting device that prevents that roller surface from peeling off.
Background technology
In the steel rolling field, the hot rolling working roll is under high temperature, working condition such as heavily stressed, and work roll surface forms the thin black bonding oxide-film of one deck easily.Oxide-film not only can reduce the friction factor between band steel and the working roll, prevents that fire check from expanding to roll body, stops the band heat of steel to spread to roll body, and can improve the surface quality of band steel.In contrast,, then will cause the uneven wear of roll surface, directly influence roll forming, dynamic roll gap and band steel section convexity if oxide-film produces inhomogeneous coming off.
According to bibliographical information, the instantaneous surface temperature of working roll is usually at the 500-700 degree in the course of hot rolling, and the roll body temperature surpasses 60 degree.The key factor that influences the oxide-film growth is the work roll surface temperature.Therefore, desirable working roll is forced cooling and is shortened the time that roll surface is in the condition of high temperature, is the important means of the oxide thickness of control roll surface, hot convexity, minimizing fire check.
For this reason, each manufacturer is through strengthening roll cooling water flow and pressure, using rolling wet goods technology to reduce roller temperature.In recent years, technical staff's way of cooling off through belt steel surface temperature before rolling of justing think reduces roller temperature.We are referred to as the anti-water that peels off usually said this cooling water.For example, through retrieval, find number of patent application " CN201020662875.5 ", name is called the patent application technology of " a kind of roller gap temperature cooling device ", and not overcome present ubiquitous cooling effect yet undesirable but it is disclosed.
But each producer effect in use is different.After deliberation, we think that main still each manufacturer inaccurate cooling effect that causes in position when installation is prevented peeling off water is not ideal enough.
That is, the problem of prior art existence is following:
1) prior art constructions form (Fig. 1) is that the anti-water collector 4 that peels off is through peeling off 3 welding of water header bracket and be fixed with one with anti-; And be installed in the below of water discharging board 2 through bolt; Though the whole fastness intensity that connects can necessarily be guaranteed; But, be unfavorable for the comparative analysis of steel rolling producers to practical application effect because the nonadjustable constraint of angle of this kind mode causes the anti-spray angle that peels off the water collector of this form to carry out free angle according to objective condition and regulates.The actual conditions that cause thus are: the machine made anti-best spray site that the water scavenging header can't calibrate to belt steel surface of peeling off of former spray angle; And the anti oxidation layer of working roll 1 roll surface of machine peels off more seriously under the off-line, and promptly this cooling device practical application effect is bad.
In addition, in rolling process, sometimes because of abnormal conditions generation steel scrap accident; And in handling the flow process of steel scrap, need the milling train counter-rotating to fall steel sometimes, and roll broken the steel scrap that is out of shape in steel; Also sometimes water discharging board below anti-peeled off water pipe and hit distortion or directly break, in this case, if change the anti-water collector that peels off of original structure form; Then necessary integral replacing, it is many so to remove parts, and it is also many to expend time in; Be unfavorable for that the fast processing after abnormal problem takes place is restorative, and operating personnel can wouldn't handle the anti-water collector that peels off of damage for guaranteeing the rolling line rhythm of production sometimes; This will certainly be not good because of the spray angle of the collector that damages yet; Cause that practical application effect is undesirable, (anti oxidation layer of the working roll roll surface of machine peels off seriously under the off-line, and the inessential roller consumption in the time of can causing the roll surface grinding rises, and directly causes production cost to increase) has little effect.
The utility model content
For overcoming above-mentioned shortcoming; The purpose of the utility model is: a kind of cooling water adjusting device that prevents that roller surface from peeling off is provided; The said anti-water collector that peels off of the cooling water adjusting device that roller surface peels off that prevents can adjust rotation according to the variation in roller footpath; To guarantee the anti-band steel that the cooling water that sprays in the water collector can be cooled to the roll inlet all the time that peels off; Cause preventing that because of guide and guards and water discharging board change in location peeling off water is sprayed onto on the roll, finally causes the roll spalling of oxide film and can directly not change the back at roller.
The technical scheme that prevents the cooling water adjusting device that roller surface peels off of the utility model is following:
