Abstract
Chromium nickel molybdenum vanadium flux-cored wire, each main auxiliary material composition is by weight percentage: ferrosilicon 2 ~ 5%, mid-carbon fe-mn 6 ~ 15%, high carbon ferro-chrome 10 ~ 25%, chromic carbide iron 6 ~ 15%, metal molybdenum 4 ~ 10%, metallic nickel 4 ~ 8%, vanadium iron 3 ~ 8%, rare earth 3 ~ 8%, fluorite 5%, all the other are iron powder; Its processing method is as follows: select main auxiliary material → weigh to main auxiliary material by weight percentage and join powder → oven dry → mix and blend; Select steel plate → cut into steel band → be rolled into U-shaped → at the finished product of the powder → Closed forming → drawing φ 3.2-φ 5mm of the in-built mix and blend of U-lag.The present invention, for the manufacture of composite abrasion-proof inner plate, has increased substantially service life, has reduced production cost.
Description
Technical field
The present invention relates to material subject engineer applied field, particularly relate to a kind of chromium nickel molybdenum vanadium flux-cored wire.
Background technology
In smelting iron and steel, mining and mill run industry, feed bin liner plate is the important equipment material in producing, the mechanical deformation stress that subject high strength during work under severe conditions and the variations in temperature of going round and beginning again, product requirement has good abrasion resistance, cracking resistance under the high temperature conditions.The liner plate of current use is substantially all adopt casting method to produce, and due to the limitation of founding materials and technique, its institutional framework is loosened, and service life is very of short duration, and the production of enterprise consumes very huge, also result in great waste to the energy.
Summary of the invention
The object of this invention is to provide a kind of chromium nickel molybdenum vanadium flux-cored wire, for the manufacture of composite abrasion-proof inner plate, can service life be increased substantially, reduce production cost.
The present invention is achieved in that chromium nickel molybdenum vanadium flux-cored wire, it is characterized in that: each main auxiliary material composition is by weight percentage: ferrosilicon 2 ~ 5%, mid-carbon fe-mn 6 ~ 15%, high carbon ferro-chrome 10 ~ 25%, chromic carbide iron 6 ~ 15%, metal molybdenum 4 ~ 10%, metallic nickel 4 ~ 8%, vanadium iron 3 ~ 8%, rare earth 3 ~ 8%, fluorite 5%, all the other are iron powder; Its processing method is as follows: select main auxiliary material → weigh to main auxiliary material by weight percentage and join powder → oven dry → mix and blend; Select steel plate → cut into steel band → be rolled into U-shaped → at the finished product of the powder → Closed forming → drawing φ 3.2-φ 5mm of the in-built mix and blend of U-lag.
The present invention, for the manufacture of composite abrasion-proof inner plate, has increased substantially service life, has reduced production cost.
Detailed description of the invention
Chromium nickel molybdenum vanadium flux-cored wire, is characterized in that: each main auxiliary material composition is by weight percentage: ferrosilicon 2 ~ 5%, mid-carbon fe-mn 6 ~ 15%, high carbon ferro-chrome 10 ~ 25%, chromic carbide iron 6 ~ 15%, metal molybdenum 4 ~ 10%, metallic nickel 4 ~ 8%, vanadium iron 3 ~ 8%, rare earth 3 ~ 8%, fluorite 5%, all the other are iron powder; Its processing method is as follows: select main auxiliary material → weigh to main auxiliary material by weight percentage and join powder → oven dry → mix and blend; Select steel plate → cut into steel band → be rolled into U-shaped → at the finished product of the powder → Closed forming → drawing φ 3.2-φ 5mm of the in-built mix and blend of U-lag.During concrete enforcement, chromium nickel molybdenum vanadium flux-cored wire is that tubulose flux-cored wire has been manufactured by special equipment, determine by the selection of alloy element (also known as medicine core), allocate, the interpolation of key alloying elements and the control of component content complete flux-cored wire and weld later product institutional framework change, make grain refinement, performance optimization, reaches the object improving product serviceability.Be chromium nickel molybdenum vanadium multicomponent alloy with the material composition of chromium nickel molybdenum vanadium flux-cored wire deposited metal, wherein the percentage by weight of Partial Elements is: C:0.5 ~ 0.7%; Si:0.5 ~ 1.5%; Mn:1.5 ~ 2.5%; Cr:5,5 ~ 7.5%; Mo:1 ~ 3%; V:0.5 ~ 1.0%; Nickel: 0.7 ~ 1%; Rare earth: 0.3 ~ 0.5%; By to the performance evaluation research of multicomponent alloy element and technological experiment, material metallurgical structure is ferrite structure, hardness HRC52 ~ 55, density of material 7.9g/cm3, and compression strength reaches 1200MPa, and impact flexibility reaches 26J/cm2, heatproof 600 DEG C.
