Abstract
The utility model discloses a mechanical transmission device for a forehearth tension roller, which comprises an entry loop, three-roller tension roller connected with motors, and an annealing furnace, wherein the motors connected with the three-roller tension roller are respectively arranged in sequence (40.5kW - 67kW - 33kW). The mechanical transmission part of the forehearth tension roller is modified, and the sequence of the motors for the three-roller tension roller is adjusted, so that the mechanical transmission device ensures the actual applied force of the tension roller, meets the process requirements and solves the problems that the strip steel is drawn down in the furnace during plate thinning, and the strip steel slips at the tension roller due to the insufficient applied force from the tension roller during plate thickening.
Description
Technical field
The utility model relates to a kind of stokehold tensioning roller mechanical transmission of stainless-steel sheet continuous annealing pickling unit.
Background technology
Stainless-steel sheet continuous annealing pickling unit is a production unit with functions such as annealing, ball blast, pickling of producing 300000 tons per year.Unit was gone into operation so far in 2006, moved 3 years continuously, had produced large quantities of qualified products.As domestic article one hot-rolled stainless steel continuous annealing pickling unit, this unit has been given play to very big economic benefit.But along with the user to the improving constantly of product quality requirement, according to market demand, this unit must can satisfy the requirement of production 16mm thickness of slab product.But because former unit capacity designs by the thickest 12mm, therefore, aspects such as unit equipment ability and transmission control need be adjusted, adjustment and technological transformation.
Existing stokehold tensioning roller is four roller tensioning rollers, and wherein a rod is free roller, and other three rollers are connected with motor, and the power of motor that is connected with three rollers is in proper order:
Entry loop → 33KW → 40.5KW → 67KW → annealing furnace
Because stove internal tension coefficient is little, and the entry loop coefficient of tension is big, and above-mentioned power of motor design is unreasonable, with production technique actual require inconsistent.1# roller power is not enough, and 3# roller power is brought into play to be come out again, causes actual the exerting oneself of a whole set of tensioning roller to be far smaller than processing requirement, when the problem that shows on the final production is thin plate, and band steel drawing down in stove; Tensioning roller is exerted oneself inadequately during slab, and the band steel skids at the tensioning roller place.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of stokehold tensioning roller mechanical transmission reasonable in design is provided.
Technical scheme: stokehold described in the utility model tensioning roller mechanical transmission, comprise entry loop, three roller tensioning roller and the annealing furnaces that are connected with motor, the motor of described three roller tensioning rollers is followed successively by 40.5KW → 67KW → 33KW in proper order.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: the utility model is transformed the mechanical driving part of stokehold tensioning roller, adjust the motor order of three roller tensioning rollers, actual the exerting oneself that guarantees tensioning roller satisfied processing requirement like this, band steel drawing down in stove when having solved thin plate, tensioning roller is exerted oneself inadequately during slab, and the band steel is in tensioning roller place problem of slip.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in the figure, a kind of stokehold tensioning roller mechanical transmission comprises entry loop, three roller tensioning roller and the annealing furnaces that are connected with motor, and the motor of described three roller tensioning rollers is followed successively by 40.5KW → 67KW → 33KW in proper order.
Above-mentioned transformation only need be shifted to motor, step-down gear, and its base need redesign and make.
Claims (1)
