Abstract
The utility model relates to the steel rolling equipment field, particularly relates to an anti-scaffolding furnace bottom roller for steel rolling. The anti-scaffolding furnace bottom roller for the steel rolling comprises a furnace bottom roller body which is in a cylinder shape; supporting shafts are arranged at two ends of the furnace bottom roller body; a carbon-ceramic composite material separation layer sleeved or fixed on the external surface of the furnace bottom roller body in an interference fit mode or a bolted connection mode. According to the anti-scaffolding furnace bottom roller for the steel rolling, the carbon-ceramic composite material separation layer which is made of carbon-ceramic composite materials covers on the external surface of the furnace bottom roller body, so that oxidizing materials can be completely insulated from being in contact with the roller body and the scaffolding forming problem of the roller body is solved; meanwhile the operation is simple; the carbon-ceramic composite material separation layer can be replaced; the service life of the furnace bottom roller is prolonged.
Description
Technical field
The utility model relates to the steel rolling equipment field, especially designs anti-dross hearth roll for a kind of steel rolling.
Background technology
The roller class directly contacted with steel plate under the conditions of high temperature such as the reel that iron and steel enterprise is used at present, hearth roll, steel plate is done the used time in the oxidation that stands the air dielectric under the condition of high temperature, corrosion etc., can form oxidation particle.There is certain wettability between the body of roll and oxide, cause particle aggregation, grow up gradually, condense at body surface, form wart like structure, have a strong impact on the surface quality of rolled plate.For the treating method of the effective solution of nothing temporarily in the current industry of this practical challenges.
The utility model content
Technical problem to be solved in the utility model is to provide anti-dross hearth roll for a kind of steel rolling, avoids occurring oxidation particle, prevents the generation of wart like structure on roller.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: anti-dross hearth roll for a kind of steel rolling, comprise cylindrical hearth roll body, the two ends of described hearth roll body are equipped with bolster, and the outer surface of described hearth roll body is set with carbon ceramic composite material interlayer.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described carbon ceramic composite material interlayer is formed in one, and adopts the mode of interference fit that described carbon ceramic composite material interlayer cover is installed on the outer surface of described hearth roll body.
Further, described carbon ceramic composite material interlayer is the Split modular structure, by bolt, the modules of described carbon ceramic composite material interlayer is fixed on the outer surface of described hearth roll body.
Carbon ceramic composite material (C/-SiC) is the carbon fibre reinforced silicon carbide ceramic composite.Main matrix composition carborundum is determining the hardness of composite, and carborundum hardness is only second to diamond; The effect of carbon fiber is mechanical strength and the fracture toughness that improves material, and its intensity is more than 5 times of steel.The carbon ceramic composite material have density low and high temperature antioxygenic property good, corrosion-resistant, be high temperature structural material and the functional material that a kind of energy meets 1650 ℃ of uses.
The beneficial effects of the utility model are: at the outer surface of hearth roll body, utilize the carbon ceramic composite material to make carbon ceramic composite material interlayer, thoroughly contacting of isolation oxide and the body of roll, fundamentally solve body of roll dross problem.Simultaneously simple to operate, carbon ceramic composite material interlayer can also be changed, and has increased the service life of hearth roll.
The accompanying drawing explanation
Fig. 1 is the cutaway view of a kind of steel rolling of the utility model with anti-dross hearth roll;
Fig. 2 is the side view of a kind of steel rolling of the utility model with anti-dross hearth roll.
In accompanying drawing, the list of parts of each label representative is as follows:
1, hearth roll body, 2, bolster, 3, carbon ceramic composite material interlayer.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, anti-dross hearth roll for a kind of steel rolling described in the utility model, comprise cylindrical hearth roll body 1, the two ends of described hearth roll body 1 are equipped with bolster 2, and the outer surface of the outer surface of described hearth roll body 1 and bolster 2 all is set with carbon ceramic composite material interlayer 3.
Described carbon ceramic composite material interlayer 3 is formed in one, and adopts the mode of interference fit that described carbon ceramic composite material interlayer 3 covers are installed on the outer surface of described hearth roll body 1.
In another embodiment, described carbon ceramic composite material interlayer 3 is the Split modular structure, by bolt by described carbon ceramic composite material interlayer 3 modules be fixed on the outer surface of described hearth roll body 1.
Carbon ceramic composite material (C/-SiC) is the carbon fibre reinforced silicon carbide ceramic composite.Main matrix composition carborundum is determining the hardness of composite, and carborundum hardness is only second to diamond; The effect of carbon fiber is mechanical strength and the fracture toughness that improves material, and its intensity is more than 5 times of steel.The carbon ceramic composite material have density low and high temperature antioxygenic property good, corrosion-resistant, be high temperature structural material and the functional material that a kind of energy meets 1650 ℃ of uses.
Outer surface at hearth roll body 1, utilize the carbon ceramic composite material to make carbon ceramic composite material interlayer 3, thoroughly isolation oxide and the body of roll contacts, fundamentally solve body of roll dross problem, simultaneously simple to operate, carbon ceramic composite material interlayer 3 can also be changed, and has increased the service life of hearth roll.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
