Description
Technical field
The utility model belongs to metallurgy industry continuous casting process and equipment, relates in particular to a kind of thin strap continuous casting roll surface cleaning plant.
Background technology
The twin-roll thin strip continuous casting technology is a kind of advanced person's a short flow process metallurgical technology.Typical process be directly with pouring molten steel in the molten bath that a chill roll that relatively rotates by two and can cool off fast and side seal board surround, the peripheral surface that molten steel is rotated at chill roll is cooled and solidifies, and then formation solidified shell and growth gradually, minimum place is pressed together in two crystallization roller gap cracks then, forms steel band.
The subject matter of this technology existence is as follows at present:
The difficult control of casting cycle.In casting was produced, the temperature of crystallization roller and the liquid steel temperature difference in the molten bath were big, tended to occur bleed-out, do not become to be with, be with steel to be bonded in phenomenons such as crystal roller surface.If band steel bonding is serious, not only can greatly influence casting roller overall thermal balance, also can produce impression and pit at crystal roller surface, damaging surface coating, and produce bigger roll-force.So must within a short period of time the cold steel that is bonded in roll surface be cleaned out, avoid it to follow the crystallization roller and enter the molten bath.
The crystallization roller in use because end and side seal board loose contact, causes limit portion bleed-out and produces the thread coagulum in Cast Strip, if do not remove the influence of these limit silks immediately, may tear the Cast Strip after it is further grown up and cause test failure.According to patent documentation analysis both domestic and external, as a kind of method of utilizing roll surface scraper cleaning roll surface of mentioning among the Chinese patent literature CN01142552.0, the device of fouls such as the scraper cleaning roll surface oxide inclusions of mentioning among the Chinese patent literature CN03229946.X, think and use the form of scraper more suitable by cleaning thin band continuous casting crystallization roller end face.
Existing roll surface Removal Technology has a lot, extensive use following several technology arranged:
1, the disclosed a kind of operation principle of Chinese patent literature CN2607209Y is to use a pair to be installed in roll surface scraper on the air bag, is attached on the roller with certain pressure, angle, removes the foul of roll surface, and particularly the graininess foul is mainly used in cold roll.
2, the utility model of European patent document EP887145A is a kind of Roller-surface cleaning equipment, and its principal character is: the steel wire brush that uses a row or number row can move up and down and make transverse vibration separately scrapes roll surface, removes adhesive.Though it can repair roll surface fast, but it can not effectively remove big cold bloom and limit silk, and, in order to satisfy the needs of long-time casting, equipment has proposed very high requirement to steel wire elevated temperature strength, the hardness as brush, therefore implement the comparison difficulty, manufacturing cost is corresponding to higher.
3, the feature of Japanese documentation JP06000591A is a kind of according to the load cell detection and location, the method for directly clearing up the defectiveness position then.Its cleaning plant is the brush roll that a cover can rotate, regulates the speed of grinding roll surface by changing operating pressure, but is mingled with still and can not effectively removes for bigger cold steel, and the control method complexity.
What the method for 4, mentioning among the american documentation literature US20020088602 was used is two groups of brush roll, home roll uses when normal casting, and secondary roller only uses when casting begins and finish below home roll, secondary roller purpose is to reduce the wearing and tearing of home roll, the residue of the difficult cleaning of cleaning.
5, mentioned a kind of roll surface scraper among the Chinese patent literature CN2863310Y, the form of side scraper is very simple, but can not use for a long time.
The method of the scraper cleaning roll surface of 6, mentioning among the Chinese patent literature CN1348915, scraper is positioned at the upper surface of roller, the impurity that scrapes off is removed by corresponding aspirator, for the low weight situation of impurity, this method is more favourable, but, had better directly remove safer for impurity such as slags.
The utility model content
In order to overcome the shortcoming of above-mentioned prior art, task of the present utility model provides a kind of improved thin strap continuous casting roll surface cleaning plant, can reach the purpose of cleaning roller end face.
Technical solution of the present utility model is as follows:
A kind of thin strap continuous casting roll surface cleaning plant, it comprises the side scraper, it also comprises side scraper spring plug, side scraper adjustment cover, adjusting nut, side scraper spring case and side scraper spring;
Settle side scraper adjustment cover, adjusting nut and side scraper spring on the described side scraper spring plug, side scraper spring is positioned at side scraper spring case;
Described side scraper spring case is by being bolted on the fixed mount, side scraper spring plug passes side scraper spring case and is connected with side scraper spring case by key, the side scraper is connected with side scraper spring plug by pin, and side scraper adjustment cover and side scraper spring are adjusted size by adjusting nut.
Described side is scraped jet blade and is designed to patty.
Described side scraper nose angle has the abundant point of a knife shape of chamfered edge.
Described side scraper edge anterior angle is 45 °～60 ° angles, and circumferential clearance is 15 °～20 ° angles.
The installation position of described side scraper on side scraper spring case makes side scrape the jet blade center line to become 10 ° of angles with crystallization roller side.
Described side is scraped jet blade and is made by the brass material.
The utility model is that two end faces at the crystallization roller are provided with the roll surface cleaning plant; utilize this device in time to remove cold steel and the Bian Si that is bonded in the casting cycle on the roller, avoid the repetition steel bonding, protection crystallization roller and side seal board are without prejudice; improve the quality of Cast Strip, guarantee that continuous casting carries out smoothly.
Thin strap continuous casting roll surface cleaning plant of the present utility model is provided with crystallization roller side scraper, is applicable to the metal Cast Strip of double-roll type strip caster cast thickness 1～10mm.
According to patent documentation analysis and experimental study, the material of the side scraper of crystallization roller should be softer than the material of crystallization roller, otherwise can injure the roller body.In addition, because limit, the Cast Strip silk that produces in the casting cycle is thicker,, increase its intensity so the nose angle of side scraper is bigger.In addition, the side scraper should be tight more apart from the roller end face, and shaving effect is good more.But take precautions against the crystallization roller and be subjected to the later extruding of thermal stretching it.
Major advantage of the present utility model is as follows:
