Abstract
The invention discloses a novel convection plate of a bell-type furnace. The novel convection plate comprises a convection plate and 16 ribbed plates, and is characterized in that the 16 trapezoidal ribbed plates are arranged on the convection plate, each ribbed plate is provided with an extending projection of 20mm close to a central portion, the inner ring diameter of the ribbed plates is 590mm, and the inner ring diameter of a steel reel is 610mm. Saw teeth with the height of 2mm are additionally arranged on the extending projections along a steel reel winding direction, the tooth spacing is 3mm, and the width of each sawtooth area is 90mm, so that an inner ring of the steel reel can be effectively locked up through the dead weight of the steel reel and snapping grooves of the saw teeth, and the inner ring of the steel reel is prevented from loosing during heating and cooling. The novel convection plate is further characterized in that the following manufacturing steps are carried out: (1) processing the 16 ribbed plates according to dimensions on drawings; (2) uniformly distributing the ribbed plates at the spacing of 22.5 degrees, and welding the ribbed plates in a longitudinal symmetry manner; (3) additionally arranging the saw teeth with the height of 2mm on the extending projections along the steel reel winding direction, wherein the tooth spacing is 3mm, and the width of each sawtooth area is 90mm. The novel convection plate of the bell-type furnace has the advantage that a reel core spot-welding procedure for each cold-rolled hard reel before furnace loading can be avoided.
Description
Technical field
The present invention relates to cold-strip steel equipment technical field, more particularly, to a kind of novel hood-type furnace convection plate, particularly suitable
In using bell furnace production cold rolling hard coil of strip.
Background technology
Cold rolling hard coil of strip during cover annealing, due to Internal and external cycle heating and cooldown rate difference, coil of strip
Inner ring can occur loose winding situation, the coil of strip after loose winding can skid in planisher uncoiling process, causes belt steel surface
Wipe and scratch.Currently in order to solve this problem using by the way of be to roll hard volume inner ring and inner core both sides carry out spot welding.This kind of side
There is obvious shortcoming in method, need special spot-welding equipment and spot weld operation personnel, Deformation in thick (more than thickness 1.5mm) simultaneously
Due to spot-welding equipment scarce capacity, need manually to carry out spot weld operation, complex operation and there is the risk snapped.
Content of the invention
The purpose of the present invention is aiming at the problem of prior art presence, provides a kind of novel hood-type furnace convection plate, passes through
Coil of strip deadweight and frictional force form self-locking, prevent inner ring loose winding.Overcome in existing solution to spot-welding equipment and spot welding people
The dependence of member's resource, the situation preventing pine in coil of strip occurs.
The object of the present invention is achieved like this: a kind of novel hood-type furnace convection plate, including convection-plate and floor, its feature
It is: have 16 pieces of trapezoidal shape floors above described convection-plate, every piece of floor has the extension protuberance of 20mm, floor near central part
Inner ring diameter 590mm, inner ring of steel coil diameter 610mm；Highly sawed by increasing 2mm in extension protuberance along coil of strip flexing direction
Tooth, space width 3mm, saw tooth region width 90mm, effectively inner ring of steel coil can be realized by the draw-in groove of coil of strip deadweight and sawtooth locked,
Prevent inner ring loose winding in heating and cooling procedure for the coil of strip.
A kind of novel hood-type furnace convection plate, is further characterized in that, carries out by following making step:
1). according to 16 pieces of floors of drawing dimensioned, length 665mm, width 50mm-170mm, thickness 25mm, described floor board
Matter is low-alloy high-tensile structural steel；
2). floor is spaced 22.5 degree and is uniformly distributed, floor welding symmetrical above and below；Every piece of floor has the extension of 20mm near central part
Protuberance, floor inner ring diameter 590mm, inner ring of steel coil diameter 610mm；
3). by extending protuberance along coil of strip flexing direction increase 2mm height sawtooth, space width 3mm, saw tooth region width
90mm；When sawtooth makes, floor thickness 29mm, using the flat back-end region of milling machine milling to 25mm thickness, saw tooth region adopts milling machine
Mill out sawtooth.
Compared with prior art, the invention has the advantage that cold rolling hard volume can be saved often roll up the core spot welding before shove charge
Program, has saved the operation and maintenance cost of spot-welding equipment, and spot weld operation personnel, avoids the artificial spot welding of think gauge simultaneously
Snap risk.
