Description of the Related Art As a process roll for transporting cold steel strips such as deflector rolls, pinch rolls, bridle rolls, steering rolls, ringer rolls, etc., the steel strips are subjected to tensioning for transport or straightening. It is known that the life of the roll is shortened due to the abrasion of the process roll for transport because the transport is performed while the roll is transported.
It is also known that the roll surface is plated with Cr for use in order to prevent abrasion of the roll, and rubber is arranged on the roll surface to prevent slipping of the steel strip.

を目的とするものである。As described above, in a roll having a Cr surface plated with Cr, when foreign matter such as iron powder is caught between the rolls during transport of the steel strip,
The steel strip has a flaw and deteriorates the quality. Further, when it is used as a ringer roll, there is a defect that the drainage of the steel strip cannot be surely performed. Further, in a roll having rubber arranged on the surface, abrasion resistance is inferior, and when the steel strip is broken, the rear end of the broken steel strip may be steep. And become unusable,
There are problems such as shortening the roll life. The present invention has been made in order to advantageously solve such a problem, a buffer material is arranged on the surface of the circular core material, the surface is coated with a cermet or a ceramic sprayed film, and it is excellent in resistance to push flaws and the like. Another object of the present invention is to provide a process roll for transporting cold steel strip.

特徴とする冷間鋼帯搬送用プロセスロールである。A feature of the present invention is that a cold-rolled steel strip is characterized by arranging a cushioning material on the surface of a circular core material and coating the surface with a cermet or a ceramic sprayed coating. It is a process roll for transportation.

機能を発揮することができる。BEST MODE FOR CARRYING OUT THE INVENTION As a cushioning material on the surface of a circular core material (including a cylinder), for example, a polymer material such as urethane rubber or nitric rubber is arranged, and the surface thereof is coated with a sprayed film of cermet or ceramics. Then, the cold rolled steel strip is used as a process roll. As such a cushioning material,
When foreign matter such as iron powder is caught during the transportation of steel strips, the part has a cushioning function to prevent the occurrence of dents in the recessed steel strips. A layer thickness of 15 to 50mm ensures a cushioning function. Can be demonstrated.

できる。Further, by coating the surface of the cushioning material with a sprayed film of cermet or ceramics so as not to generate flaws on the surface of the cushioning material when foreign matter is bitten in, the flaws, wear, and flaws of the cushioning material as described above are formed. Prevent. As such a sprayed film, for example, Ni, Ni-Cr, Co,
Cr, Al, Y, Mo, W, Ti, V, Ta-based metals and the like and WC, TiC, NbC, Cr 3 C 2 , Al 2 O 3 , C
As the cermet made of ceramics such as r 2 O 3 and ZrO 2 , and as the ceramics, the above ceramics can be spray-coated. Such a cermet or ceramics can form a sprayed film by gas flame spraying, plasma spraying or the like which is generally performed.

覆することができるものである。In such thermal spraying, when the thermal spray material of cermet or ceramics is projected onto the surface of the cushioning material (polymer material), the surface layer portion of the polymeric material is heated by the heat of the thermal spray material to be in a molten state. The impact force of the projection causes the polymer to diffuse to the surface layer of the polymer material, so that the polymer can be firmly coated. That is, the surface layer of the polymer material is in a molten state and has a function as a binder, so that the sprayed film can be firmly coated.

When foreign matter is caught at 5 to 20 μm as described above, it does not cause flaws on the surface of the cushioning material, and can sufficiently exert its function as a cushioning material, so that flaws are formed on the steel strip. Can be reliably prevented.
