Abstract
The utility model relates to a device for steel rolling, particularly a compound roll. The utility model is characterized in that a roll base body 1 and a surfacing anti-friction layer 2 form the compound roll, the working surface between the two rolling rings of the roll base body 1 is covered with the surfacing anti-friction layer 2, and the working surface between the two rolling rings of the base body of the roll base body 1 is covered with the surfacing anti-friction layer 2 through adopting a common surfacing process. The utility model has the advantages of reasonable structure and long service life. The utility model can also reduce the frequency of roll changing and the production cost of the steel rolling.
Description
The utility model relates to a kind of steel rolling equipment, particularly roll.
In steel rolling was produced, roll was worked under hot environment and is worn and torn repeatedly, and working face very easily damages.Roll of the prior art generally is to be material with 70Mn, and the roll wearability and the hardness of this material are all relatively poor, so the life-span is low.Use this roll, need the frequent roll of changing in the production, influence output, increased production cost simultaneously.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and provides a kind of anti-wear performance good roll, improves roll service life, reduces cost.
The technical solution of the utility model is: constitute composite roll by roller substrate and build-up wear-resistant layer, the build-up wear-resistant layer covers on the working face of roller substrate.
Adopt common bead-welding technology, the build-up wear-resistant layer is covered on the working face between roller substrate two collars.
Because working face covers the build-up wear-resistant layer, makes improve greatly the service life of roll, reduce the roll change number of times, the corresponding production cost that reduced the utlity model has characteristics such as rational in infrastructure, long service life.
Accompanying drawing is the structural representation of an embodiment of the utility model.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
Present embodiment is the roll that 650 milling trains use, composite roll is made of roller substrate (1) and the overlay cladding (2) that covers on the working face between roller substrate two collars, roller substrate adopts the steel alloy casting to form, and with common bead-welding technology the build-up wear-resistant layer is covered on the working face between roller substrate two collars.
Claims (1)
1, a kind of composite roll is characterized in that roll is made of roller substrate (1) and build-up wear-resistant layer (2), and build-up wear-resistant layer (2) covers on the working face between roller substrate (1) two collars.
