Abstract
The utility model relates to a magnesium oxide coating device of coating machine, it includes scribbles the roller, scribbles roller, left branch roller, right branch roller and steel band down, and the steel band is worn and is scribbled the roller and scribble the clearance of roller down last, and put up respectively at left branch roller and right branch roller both sides, characterized by: on scribble the roller the lower surface be less than the upper surface of left branch roller and right branch roller. The steel band becomes to be greater than 20 cornerites by left branch roller and right branch roller at the last roll forming of scribbling among this magnesium oxide coating device of coating machine. The utility model discloses the selection of preferred is: the steel band is 50~80 by left branch roller and right branch roller in last angle of scribbling the cornerite of roll forming one -tenth. This magnesium oxide coating device of coating machine changes the steel band and the position of scribbling roller, left branch roller down, makes the steel band scribble the roll forming on with and becomes the cornerite, and the coating volume reaches 5~7 gm2, reaches process standard's requirement.
Description
Technical field
This utility model relates to the device of a kind of magnesium oxide coating, is specifically related to the magnesium oxide coating dress of a kind of coating machine
Put.
Background technology
Orientation silicon steel, after decarburizing annealing, needs the upper and lower surface even application magnesium oxide masking liquid at steel band.Oxygen
Change magnesium and act primarily as the effect of interleaving agent, prevent steel band from producing bonding in high-temperature annealing process, while with the dioxy of steel strip surface
SiClx thin film reacts, and forms magnesium silicate bottom.Therefore magnesium oxide masking liquid is at the direct shadow of coating effect on orientation silicon steel surface
Ring whether steel band produces bonding in high-temperature annealing process,
Magnesium oxide coating at present is realized by double-roller type coating machine.Paint roller is divided into paint roller and lower paint roller, its table
Face is the rubber with cutting, and strip steel is through the gap upper and lower paint roller, and when steel band moves, strip steel leads to upper and lower paint roller
The effect crossing friction drives upper and lower paint roller to rotate, thus carries out the coating of steel band two sides magnesium oxide masking liquid.Strip steel produces at present
The tension force of gravity and strip steel is all undertaken by lower paint roller, owing to steel band lower surface is by the squeezing action of lower paint roller so that it is following table
The coating amount of face magnesium oxide generally only has 1～2g/m2, much smaller than normal process standard one side coating amount 5～7 g/m2Requirement,
The unit speed of pilot scale line is only 1～2m/min simultaneously, it is impossible to the same with normal production line, can be by improving the operation of unit line
Speed makes up the deficiency of lower surface masking liquid coating amount.CN 102407210A patent is wherein mentioned middle-size and small-size orientation silicon steel MgO
It is coated with coating control method and according to CN 102179347 A arranges method before application that support roller, strip steel lower surface magnesium oxide
Coating amount does not reaches requirement yet.How to solve this problem, presently relevant document does not also have the report of this respect.
Summary of the invention
In order to overcome in prior art, the above-mentioned deficiency of the magnesium oxide applying device of coating machine, this utility model provides one
Plant and avoid steel band in high annealing owing to magnesium oxide coating amount is inadequate, the magnesium oxide applying device of bonding coating machine occurs.
Idea of the invention is that, for avoiding the steel band gravity squeezing action to lower roll, by upper paint roller and the lower painting of coating machine
Roller position is moved vertically downward, makes steel band and upper paint roller form cornerite, so carries out orientation silicon steel magnesium oxide at two roller coating machines
During masking liquid coating, the coating amount of steel band lower surface magnesium oxide will be significantly improved, it is to avoid when high annealing, due under steel band
The bonding problem that surface coating amount is few and produces.
The magnesium oxide applying device of this coating machine includes paint roller, lower paint roller, left roller, right roller and steel band, and steel band is worn
In the upper paint roller gap with lower paint roller, both sides frame respectively props up roller and right roller on a left side, it is characterized in that: the lower surface of upper paint roller
Less than a left side roller and the upper surface of right roller, steel band and upper paint roller is made to form cornerite.
The magnesium oxide applying device of above-mentioned coating machine, is characterized in that: steel band is propped up roller with right roller at upper painting roll forming by a left side
Become more than 20 ° of cornerites.
This utility model compared with selection be: the angle that steel band is propped up, by a left side, the cornerite that roller and right roller are formed in upper paint roller is
50 °～80 °.
The utility model has the advantage of when usual pilot scale line low speed carries out the coating of orientation silicon steel magnesium oxide, change steel band
With lower paint roller, the position of left roller, steel band and upper paint roller is made to form cornerite, it is possible to significantly improve the coating amount of lower surface, be coated with
Deposited amount reaches 5～7 g/m2, reach the requirement of technological standards.The method is simple to operate, convenient and easy, and effect is notable.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of embodiment of the present utility model.
In above-mentioned figure
Paint roller on 1, roll body on 2, roller cutting rubber on 3,4 times paint rollers,
5 times roll bodies, 6 lower roll cutting rubber, 7 steel bands, 8 right rollers,
9 left rollers.
Detailed description of the invention
Below by embodiment and accompanying drawing detailed description detailed description of the invention of the present utility model thereof, but tool of the present utility model
Being confined to following embodiment under body embodiment, following embodiment is to explanation of the present utility model.
Embodiment
The device of the present embodiment is shown in Fig. 1, and it includes paint roller 1, lower paint roller 4, left roller 9 and right roller 8,
The upper paint roller 1 of coating machine and the position of lower paint roller 4 are moved vertically downward, by the lower surface of upper paint roller 1 less than a left side
Propping up roller 9 and right roller 8 upper surface, make steel band 7 and upper paint roller 1 form cornerite, the present embodiment steel band 7 moves from right to left, works as steel
Friction, lower surface and lower paint roller is produced by the gap between upper paint roller 1 and lower paint roller 4, steel band 7 upper surface and upper paint roller 1 with 7
4 produce friction, drive upper paint roller 1 and lower paint roller 4 to rotate the upper and lower surface of steel band 7 due to the effect of friction when steel band 7 moves
The coating of magnesium oxide masking liquid.The coating amount of steel band 7 lower surface magnesium oxide can be significantly improved, it is to avoid move back at high temperature by this device
During fire, the bonding problem produced owing to steel band 7 lower surface coating amount is few.
This device steel band 7 forms the cornerite more than 20 ° with upper paint roller 1 in coating process.
The cornerite size that the present embodiment steel band 7 is formed with upper paint roller 1 is 50 °～80 °.
