Anti-scaffolding furnace bottom roller used for steel rolling and manufacturing method thereof

Abstract

The invention relates to the field of steel rolling equipment, in particular to an anti-scaffolding furnace bottom roller used for steel rolling and a manufacturing method of the anti-scaffolding furnace bottom roller. The anti-scaffolding furnace bottom roller used for the steel rolling comprises a furnace bottom roller body in a cylindrical shape, supporting shafts are arranged at the two ends of the furnace bottom roller body, a carbon-pottery composite material layer is sleeved on the outer surface of the furnace bottom roller body, and the carbon-pottery composite material layer is sleeved or fixed on the outer surface of the furnace bottom roller body in an interference fit or bolted connection mode. Carbon-pottery composite material is adopted for manufacturing the carbon-pottery composite material layer on the outer surface of the furnace bottom roller body, the roller body can be thoroughly isolated from oxidizing material, therefore the scaffolding problem of the roller body is solved fundamentally, meanwhile, the operation is easy, the carbon-pottery composite material layer can further be replaced, and therefore service life of the furnace bottom roller is prolonged.

Description

technical field [0001] The invention relates to a hearth roll and a manufacturing method thereof, in particular to design a nodulation-preventing hearth roll for steel rolling and a manufacturing method thereof, belonging to the field of steel rolling equipment. Background technique [0002] At present, the rolls used by iron and steel enterprises, such as reels and hearth rolls, which are in direct contact with the steel plate at high temperature, will form oxide particles when the steel plate is subjected to oxidation and corrosion of the air medium at high temperature. There is a certain wettability between the roll body and the oxide, which causes the particles to aggregate, grow up gradually, and condense on the surface of the roll body to form tumor-like protrusions, which seriously affects the surface quality of the rolled sheet. There is currently no effective solution to this practical problem in the industry. SUMMARY OF THE INVENTION [0003] The technical probl...

Problems solved by technology

There is a certain degree of intrusion between the roll body and the oxide, which causes the particles to gather, gradually grow up, and condense on the surface of the roll body to form nodules, which seriously affects the surface quality of the rolled plate.

There is currently no effective solution to this practical problem in the industry
