Abstract
The invention relates to a process of a nickel-based high-temperature alloy flux-cored welding wire on a hard surface of a wrapper roller. The process is characterized by comprising the following steps that: the nickel-based high-temperature alloy flux-cored welding wire is adopted, direct-current submerged-arc welding equipment is utilized to carry out surfacing, the surfacing layer is 3-5mm, and after welding, the wrapper roller is preheated to 600 DEG C to carry out heat treatment; and after cooling, a cold-extrusion processing method is used to enable the metal hardness of the surfacing layer to be more than HRC50. The process has the advantages that the material of the surfacing layer is nickel-based high-temperature alloy, no steel bonding is caused in use, complete alloy combination is realized for the surfacing layer and a matrix, no stripping can be caused in use, the welding layer generates the processing hard surface after cold processing, the hardness is high and the wear resistance is good.
Description
Technical field
The present invention relates to the technique for overlaying field, relate in particular to a kind of technique helping winding up roller stiff dough nickel base superalloy flux-cored wire.
Background technology
The use of steel mill's rolling-assisting device becomes more scabrous problem in the industry all the time, in use roll surface easily produces steel bonding, and make roll surface form raised points and affect product quality, technique in this class roll manufacturing formula reparation is: the one, and the pile-up welding hard alloy layer, the 2nd, thermal spraying nickel chromium triangle borosilicate is from ironing alloy, but these two kinds of methods are existent defect all, before a kind of be well to solve the problem of steel bonding, so the life-span of only using of roller can only be about half a year, though then a kind ofly can solve the steel bonding problem, but because alloy-layer and the parent of thermal spraying are half metallurgical binding, peel off so in use easily produce, and cause roll to use, therefore, for addressing the above problem, the spy provides a kind of new technical scheme to satisfy the demands.
Summary of the invention
The purpose of this invention is to provide the technique that is always helping winding up roller stiff dough nickel base superalloy flux-cored wire.
The technical solution used in the present invention is:
In the technique that helps winding up roller stiff dough nickel base superalloy flux-cored wire, described processing step is: welding wire adopts the nickel base superalloy flux-cored wire, utilize direct current submerged-arc welding equipment to carry out built-up welding, overlay cladding is 3-5mm, postwelding, to help winding up roller to be preheating to 600 ℃ and heat-treat, after the cooling, adopting the method for cold extrusion processing is that surfacing layer metal hardness hardens to more than the HRC50.
The percentage by weight of described nickel base superalloy flux-cored wire is the Cr of 10-20%; The Mn of 0-5%; The Si of 0-2%; ≤ 0.02% S; ≤ 0.02%P; The W of 0-5%; The Mo of 10-20%; The Co of 0-3%; The V of 0-2%; The Nb of 0-5%; The Ni of 0-5%.
Advantage of the present invention is: weld overlay materials is nickel base superalloy, non-stick steel in the use, and overlay cladding and parent are combined for alloy completely, and can not produce in the use and peel off, the processing stiff dough that layer produces after cold working, the hardness high-wearing feature is good.
