Description
Technical field
The present invention relates to continuous casting technology, keep the method for direct casting behind particularly a kind of thin strap continuous casting broken belt.
Background technology
The twin-roll thin strip continuous casting technology is a kind of advanced person's a short flow process metallurgical technology.Typical example as shown in Figure 1, directly pouring molten steel is relatively rotated the casting roller 1a that also can cool off fast at one by two, 1b and side seal board 2a, in the molten bath that 2b surrounds, the peripheral surface that molten steel is rotated at the casting roller is cooled and solidifies, and then the formation solidified shell is also grown gradually then at two crystallization roller 1a, minimum place, 1b roll gap crack is pressed together, form band 4, band is via guide plate 5 guiding kink guide roller 12 and pinch rolls 6, and at kink guide roller 12 and casting roller 1a, form kink 3 between the 1b, be rolled into strip by milling train 7 then, drive through spray cooling device 9 by rollgang 8 then and cool off, send into crimping machine 11 at last through crimping machine pinch roll 10 and curl.
It is fast that the production of thin strap continuous casting has speed, the characteristics that flow process is short.And in thin strap continuous casting technology, the process condition at casting initial stage is very complicated, the temperature of crystallization this moment roller is lower, and the liquid steel temperature in the molten bath is also lower, causes casting strip quality poor, be not easy into band, described in typical process, if this moment be left intact, then exist mass defect take the lead can be directly oriented to subsequent handling, very likely at the milling train place or coiling machine inlet the obstruction accident takes place, whole casting operation failure.
In addition, need to switch crimping machine in the direct casting, after promptly a coiling machine reaches its curling weight, need to stop the operation of curling, production line is changed the operation of curling of another coiling machine, in some documents, be that shear arrangement is set behind milling train as the method for mentioning among patent CN1358119A, US6698498 and the CN1297793, after being disconnected, the Cast Strip switches coiling machine again.
But also there are some additive methods to save shear arrangement, technological parameters such as employing speed change described in U.S. Pat 2004104006A and WO02076655A1 or change roll gap make the Cast Strip locate to rupture in the outlet (nip point) of casting machine, thereby reach the purpose of broken belt.In these methods, great majority are to adopt the swing guide device to keep the post-rift casting continuity in Cast Strip in casting machine, and the form of swing guide is different, make it can enter next process smoothly but purpose all is the guiding Cast Strip.
The thin strap continuous casting direct casting method that also has is as follows:
Method described in U.S. Pat 2004104006A1, the WO02076655A1 is to utilize fixing casting rate and the relation between the thickness of Cast Strip, pace of change when needs disconnect the Cast Strip, deficiency broken belt under the effect of own wt is solidified in the Cast Strip, avoid using external equipment to come the Cast Strip is sheared, the method is fine, but control more complicated, and take the lead shape as the Cast Strip that the method obtains certainly will be very poor, be unfavorable for that the Cast Strip imports subsequent handling, cause the casting failure easily.
A kind of flying shear of mentioning among the Chinese patent CN1297793 is comprising two pairs of cutting edges, three guide channels.When cutting underproof waste material head, can waste material be moved on to another collecting box by mobile guide passage a and handle, normal product is then sheared in gathering sill b smoothly, and the product of afterbody is then cut apart among another gathering sill c.This processing method is applicable to the shearing of bar steel, and the band steel be because width restriction can't frequently move away the conveying raceway, so can not realize real-time shearing, for the continuous production of Cast Strip certain restriction is arranged.
The method of mentioning among Chinese patent CN1358119A and the US6698498B1 is to add shear arrangement at the pinch roll rear portion of thin strap continuous casting production line, in case the Cast Strip defect detector detects the Cast Strip defective, then cutter work, the Cast Strip is cut into discrete length, and the scrap collecting tank that the part that has arrangement for deflecting that the Cast Strip is cut is sent into along certain raceway, treat that casting strip quality normally batches after stable again, is still introduced the Cast Strip in the coiling machine by arrangement for deflecting.This method can guarantee Continuous Casting Stability, can eliminate the mass defect of Cast Strip.But mechanism is huge, complicated operation.
The method that Chinese patent CN1665619A mentions is to adopt the guide plate that can move horizontally, when Cast Strip fracture and normal band excessively, use as Cast Strip guiding deflection system, but this method requires the swing guide translational speed rapid, and its result of use is difficult to guarantee under the situation that does not have the broken belt checkout gear to cooperate.
The structure of having mentioned in the U.S. Pat 2004040689 among a kind of swing guide structure and the present invention is similar, also adopt the double-swing guide plate as band steel guider in this scheme, but it does not have the function that keeps casting to work continuously behind the broken belt.
In sum, produce successional needs, must initiatively rupture in the Cast Strip or passive unexpected fracture back keeps the continuity of casting operation, thereby reach the purpose of steady production for thin strap continuous casting.
Summary of the invention
The objective of the invention is to propose keep behind a kind of thin strap continuous casting broken belt the method for direct casting, in the casting cycle no matter the Cast Strip initiatively rupture or unexpected passive fracture after can keep the casting operation continuity, thereby reach the purpose of steady production, and can improve simultaneously to open and water success rate.The present invention is applicable to the strip steel of twin-roll thin strip continuous casting production 1-5mm.
