YD322 1.2mm 1.6,mm 57~62 is used for surfacing welding of various punching dies,cutting tools and repair of mechanical parts requiring high wear resistance.Hardfacing of YD350 1.2mm 1.6,mm 32~35 continuous casting rolls.Hardfacing of YD351 1.2mm 1.6,mm 38~42 continuous casting rolls.YD352 1.2mm 1.6,mm 45~50 continuous casting roll surfacing weldingChina Cost Effective Wear Resistant Hardfacing Mill Roll Cost Effective Wear Resistant Hardfacing Mill Roll Cladding Flux Cored Welding Wire Name:LM001 1.6-2.8mm HRC30-45 C:,1.0% Mn:0.5-1.5% Si 2.0% Cr:12-19% Ni 1.0% LM001 is a tubular wire for submerged arc hardfacing,which is designed for buffer layer forChina Stable Arcless Spatter Hardfacing Flux Cored Wires CF11 is submerged arc hardfacing flux cored wire,deposited metal is Cr low carbon alloy with high bonding strength and good toughness.it is used as buffer layer and buildup layer for continuous casting roller,cold rolling backup roller etc.
The hardfacing layers were made on a 120 × 350 × 50 mm plate in two layers on the plasma hardfacing machine PPC 250 R6. Rollers in steel continuous casting system are one of the supporting Hardfacing wire LM430 - Leigong welding alloysCLASSIFICATION.EN14700 DIN 8555 T Fe 7 MF 5-250-PRT CHARACTERISTICS.LM430 is submerged arc arc flux cored wire,shielding flux HJ260,alloy depositing a ferritic steel containing17% chromium,used for resistant to corrosion and oxidation at high temperature,as buffer-layer before hardfacing with 13 % chromium martensitic alloys.High Chromium Version Of Common Chromium CarbideHigh abrasion resistant wear plate for hardfacing continuous casting roller High chromium version of common chromium carbide overlay cco wear plate Wodon hardfacing bimetallic wear resistant steel plate for cement plants
Flux cored wire for hardfacing of parts subjected to metal-to-metal wear (adhesion),moderate impact,creep,thermal fatigue and corrosion at high temperatures.Especially designed for hardfacing and renovation of continuous casting rollers,where high hardness is required.SHF 604 is the suitable flux for these hardfacing applications.News and Updates - CST Pvt.Ltd.-The Hardsurfaced RollsWe also provide turnkey solutions to install hardfacing facilities in-house. dies is also our expertise.We cover everything from forged steel rolls,roller jackets,complete roll assembly for continuous casting machines and hot strip mills,to rolls for slab casters,CSPs,plate mills,hot strip and steckel mills,including high Possibilities for Using New Types of Additive Materials The paper presents the results of the research aimed at quality determination of cladding layers for renovation of the rollers during continuous casting of steel.Four newly designed additive materials in the form of filled tubular wires of diameter 2.4 mm were evaluated.Additive materials were experimentally designed for the renovation of support rollers of the hot rolling mill.
We offer one,two and three layer solutions for the repair of continuous casting rollers with proper-ties optimized for the various wear systems occurring along the line.Next to the steel mills themselves,we co-operate with manufacturers of continuous casting lines and with technical universities.We are at home in steel mills.Resource-saving hardfacing by arc welding with flux-cored The high hardness (57-60 HRC) of the hardfaced roll surface is achieved due to the formation of martensitic structure strengthened with dispersed carbides (Fig.7),as well as due to the diminution of the primary structure grain by performing hardfacing welding with the 2.0 mm diameter wire under conditions which combine in the optimal way the welding deposition rate and heat input.The rollsurface temperature during steady state service conditions can exceed 500 'C,and mate
