Abstract
The utility model discloses a kind of Quartz Ceramic Roller for electrical steel continuous annealing stove heat section, the both ends of the surface of described ceramic roller main body are respectively evenly equipped with the blind hole of 6 and match with flange plate bolt hole; Between described metal core axle and ceramic body, adopt the plug-type connecting mode of ring flange six bolt to prevent the axial rotation of ceramic body and metal core axle, and prevent the radial-play of ceramic body and metal core axle by shielding tight relative screw.This ceramic roller has replaced traditional carbon cover roller, overcome the generator tool rubbing effect under hot environment of band steel and ceramic roller, cause the various oxide particles of roll surface and iron filings etc. to be reduced and melting, bonding under the reducing atmosphere environment that contains high concentration hydrogen, the undesirable element of growing up is layering, improve operating rate, reduce the consumption of furnace roller.
Description
Technical field
The utility model relates to a kind of Novel ceramic roller, relates in particular to a kind of Quartz Ceramic Roller for electrical steel continuous annealing stove heat section.
Background technology
The quality of the Quartz Ceramic Roller of electrical steel continuous annealing stove is to affect operating rate and product surface quality is one of principal element.The furnace roller of existing electrical steel continuous annealing stove heat section is also continued to use carbon cover roller always, and its work-ing life and quality are perplexing the production of electrical steel always.Because carbon cover roller surface is softer, the surface of roller is easily by scratch of steel strip, also easily iron powder accumulated and buildup of scuffing place, although the relative steel rider of carbon cover roller has been alleviated the dross cycle, the work-ing life of carbon cover roller is short, in addition, due to ceramic jacket and roller core coupling part unreasonable, once be heated, can cause steel roller core that ceramic jacket is risen brokenly, often increase production cost.
Publication number is to disclose " a kind of Novel silicon steel annealing furnace ceramic roller device " in the utility model patent of CN 202925060U, and its roller-way structure be can solve over the thermal expansivity of steel roller core and causes ceramic jacket to be subject to the problem of thermal rupture higher than the thermal expansivity of ceramic jacket.But the ceramic roller of this structure very easily produces surface cord at electrical steel annealing furnace continuous operation, and its roll surface also easily produces oxidation, loose and the phenomenon such as peel off, particularly furnace temperature is when more than 900 DEG C, the easy flexural deformation of its metal core axle, has had a strong impact on the stably manufactured of electrical steel product.
Summary of the invention
In order to overcome carbon cover roller that existing electrical steel continuous annealing stove uses because of dross, roll surface oxidation, loose and peel off and grinding roller, improves operating rate, reduces the consumption of furnace bottom roll.The utility model provides a kind of Quartz Ceramic Roller for electrical steel continuous annealing stove stove heat section.
The technical solution of the utility model is as follows: comprise that inner is hollow ceramic roller main body, be enclosed within the metal core axle in ceramic roller main body and be assemblied in the ring flange at two ends, ceramic roller main body left and right, described ring flange bottom surface is circular bottom surface, on this circular ground, be evenly provided with at least three bolts hole, ring flange left and right side is provided with two symmetrical open holess, between described metal core axle and ceramic body, fix by the plug-type connecting mode of flange plate bolt, this connecting mode has limited the axial rotation between ceramic body and metal core axle, in the open holes of ring flange left and right side, screen tightly has relative screw, radial-play between restriction ceramic body and metal core axle.
The beneficial effects of the utility model are Quartz Ceramic Rollers of a kind of electrical steel continuous annealing stove stove heat section, surface smoothness is high, hardness is high, metal core axle, ring flange and ceramic body are running fit to adapt to the different swell incremenies in high temperature lower shaft and hole, and in the high temperature being greater than more than 900 DEG C, there are good thermostability and good oxidation-resistance, phenomenons such as solving surface cord, oxidation, loosen and peel off, therefore long service life.

Embodiment
The Quartz Ceramic Roller of a kind of electrical steel continuous annealing stove stove heat section as shown in Figure 1, comprise ceramic main body 1, metal core axle 3 and be assemblied in the ring flange 2 at two ends, ceramic roller main body left and right, for connecting the standing bolt 4 of ceramic body 1 and ring flange, the contact surface more than coordinating has certain gap, ensure under hot environment, metal core axle 3, ring flange 2 and standing bolt 4 can closely cooperate with ceramic body 1 after expanded by heating.
On ceramic roller main body 1 both sides end face, be evenly equipped with 6 blind hole 1-1 as shown in Figure 2, process by supporting frock, match with 6 bolt hole 2-2 on ring flange.The hollow wall thickness of ceramic body need meet the half that diameter of bore is outside diameter, to strengthen the intensity of ceramic roller shell.
Metal core axle is used for supporting ceramic body as shown in Figure 3, between metal core axle and ceramic body, adopt the plug-type connecting mode of ring flange six bolt to prevent the axial rotation of ceramic body and metal core axle, increase the point of contact rotating, reduce the probability cracking in clashing into, and prevent the radial-play of ceramic body and metal core axle by shielding tight relative screw.
Ring flange is axially evenly equipped with 6 bolt hole 2-2 and coordinates with 6 blind hole 1-1 on ceramic body end face as shown in Figure 4, and side is provided with screw hole 2-1 and cone-head screw and tack screw fit and uses.Ring flange is aimed at porcelain bushing center all the time.These two ring flanges and ceramic body have conical contact, allow reversibly hot distortion.
As shown in Figure 5 metal core axle 3 is inserted in ceramic body 1,6 standing bolts 4 of each left and right side are inserted in the bolt hole 2-2 of ring flange and the blind hole 1-1 of ceramic body and carry out pre-installation ring flange.Screw hole 2-1 on ring flange is aimed to metal core axle fixed orifices 3-1, the tight relative cone-head screw 6 of screen and screw with flat head 7 prevent the radial-play of ceramic body and metal core axle, adjust immediately 6 standing bolts 4 of each side to reach the gap of ring flange 2 and ceramic body 1 simultaneously, screen jack panel prevents the axial rotation of ceramic body and metal core axle, the fixing cone-head screw 6 of mode and the nut 5 that finally adopt spot welding, prevent that it from getting loose.
The structure design of this Quartz Ceramic Roller is dissolved the shearing stress on porcelain bushing, centering ability is good, and the good reversibility of thermal distortion under high temperature adds the extremely low thermal expansivity of stupalith characteristic, even if therefore axle is in the time of the highest expansion, ceramic jacket is still fixed firmly.
