Estimating the term…
The outer periphery of a heat resistant roll comprises a para aromatic polyamide fiber. The heat resistant roll is applied for conveying and picking up a steel plate heated to a high temperature. The heat resistant roll is preferably applied to the inside of a continuous annealing apparatus for annealing the steel plate or to the exit side of this apparatus. The heat resistant roll is also preferably applied to the exit side of a baking furnace in a continuous coating apparatus for coating the steel plate. The heat resistant roll is also preferably applied to the exit side of a galvanization tank in a zinc galvanizing apparatus.
A heat resistant roll for use in steel plate manufacturing equipment, the roll having an outer periphery comprising a para aromatic polyamide fiber, said outer periphery coming into contact with the steel plate heated to a high temperature.
A heat resistant roll for use in the exit side of a baking furnace of a continuous coating apparatus for coating steel plate with a coating material with steel plate manufacturing equipment, the roll having an outer periphery comprising a para aromatic polyamide fiber.
A heat resistant roll for use in a continuous annealing apparatus for annealing steel plate with steel plate manufacturing equipment, the roll having an outer periphery comprising a para aromatic polyamide fiber.
A heat resistant roll for use in the exit side of a galvanizing tank of a continuous zinc galvanizing apparatus for galvanizing steel plate with zinc with steel plate manufacturing apparatus, the roll having an outer periphery comprising a para aromatic polyamide fiber.
