Abstract
The invention relates to a flux-cored wire, which is characterized by being prepared by the following steps of: selecting alloy elements of 1.6 to 2.8 percent of silicon iron, 1.1 to 2.6 percent of medium carbon ferromanganese, 20 to 30 percent of chromium metal, 14 to 55 percent of nickel metal, 1 to 3 percent of molybdenum metal, 0.5 to 2 percent of tungsten metal, 0.1 to 2 percent of aluminum metal, 0.1 to 1 percent of niobium metal and 0.3 to 0.5 percent of titanium metal, preparing into powder, drying, mixing and stirring, filling in a hollow welding rod, and sealing to obtain a finished product. By selecting and blending the alloy elements in the flux core and controlling the content of key element components, the performance change of the flux-cored wire is completed so as to meet the process requirement of surfacing and improve the product serviceability.
Description
Technical field:
The invention belongs to material subject engineering application, mainly is a kind of submerged arc overlay welding welding material-extraordinary tubulose flux-cored wire that is applied to make and repair the industrial heating furnace furnace roller.
Background technology:
Industrial heating furnace is the important equipment during steel industry is produced, the furnace roller of working in stove is bearing up to 1100 ℃ of high temperature when working, bearing weight metal that is in the condition of high temperature and the continuous motion that goes round and begins again simultaneously, therefore the own requirement to furnace roller has good high-temperature oxidation resistance, high-temperature creep resistance and abrasion resistance.
The industrial heating furnace furnace roller that uses substantially all is to adopt casting method to produce at present, because the limitation of founding materials and technology makes that the service life of furnace roller is very of short duration, once inefficacy, must scrap, the production of enterprise consumes very huge, and the energy has also been caused great waste.
Summary of the invention:
The present invention mainly provides a kind of serial built-up welding with high temperature resistant wear-resistant flux-cored wire, and the material composition of this welding wire stacking coating metal is a multicomponent alloy, and institutional framework is an austenite, and hardness HRC28-38 still has good comprehensive mechanical properties under 1100 ℃.
Flux-cored wire is finished by special equipment production, and its processing step brief introduction is as follows: alloying element → join powder → oven dry → mixing to stir
↓
Steel plate → steel band → rolling → dress powder → closure shaping → drawing finished product (φ 3.2-φ 5)
Flux-cored wire of the present invention, be primarily characterized in that the Recipe of medicine core is by selection, the allotment to alloying element in the medicine core, the performance variation of flux-cored wire is finished in the control of key element component content, reaches the raising of satisfying bead-welding technology requirement and product serviceability.
Medicine core structural constituent content %
Ferrosilicon 1.6～2.8
Mid-carbon fe-mn 1.1～2.6
Crome metal 20～30
Metallic nickel 14～55
Metal molybdenum 1～3
Tungsten 0.5～2
Metallic aluminium 0.1～2
Metal niobium 0.1～1
Titanium 0.3～0.5
Alloy medicine core of the present invention prescription has easy to processly, and characteristic such as result of use is good can reduce the production cost of enterprise, the raising work efficiency significantly.
The specific embodiment:
Flux-cored wire of the present invention mainly is made up of hollow welding rod and medicine core, when specifically implementing, produces hollow welding rod earlier, and its production process is: steel plate → steel band → rolling → be drawn into hollow welding rod of φ 3.2-φ 5.Then, again the medicine core is prepared burden, by selection, allotment to alloying element in the medicine core, the performance variation of flux-cored wire is finished in the control of key element component content, after selecting for use ferrosilicon 1.6～2.8%, mid-carbon fe-mn 1.1～2.6%, crome metal 20～30%, metallic nickel 14～55%, metal molybdenum 1～3%, tungsten 0.5～2%, metallic aluminium 0.1～2%, metal niobium 0.1～1%, Titanium 0.3～0.5% alloying element to join powder → oven dry → mixing stirring, pack in the hollow welding rod, seal, make finished product.
