The article considers the issue of influence nature core powder strip on properties wear-resistant deposited layer in relation to operating conditions parts backfilling devices blast furnaces. It is shown that introduction a complex-alloyed alloy into ribbon electrode instead mechanical mixture components increases uniformity wear metal due homogeneous distribution chemical elements component composition ribbon. This contributes formation with better and uniform structural phase, which...
The main types of flux-cored strip electrode materials for mechanized arc surfacing alloyed and composite alloys are discussed. Surfacing with these strips results in the formation required properties working surfaces components. Special features melting deposited layer welding technological also discussed, taking into account production technology strips.
A mathematical model of the stress–strain state in drawing flux-cored wire, which takes into account actual distribution geometrical parameters, mechanical properties, and conditions contact friction at bottom deformation zone, is developed. The also possibility plastic sheath.
A mathematical model of the stress–strain state metal in process rolling flux core different metallic shells is developed. The takes into account effect shell on geometrical and energy–force parameters flux-cored electrode tapes also physical–mechanical properties core.
AbstractThe proposed automated program takes into account changes in the geometrical parameters during drawing, mechanical properties and contact friction conditions along length of deformation zone, also plastic shell fracture shell. It is shown to be possible produce defect-free flux-cored wires at minimum number passes.Keywords:: ratiocontact stressshearing stresslevel front rear tensionautomated analysis
It is shown that the longitudinal magnetic field of welding current in two sheets transforms to a single sheet and this confirms electromagnetic nature interatomic binding forces. At gap 0.002 m as result separation lines force, induction rapidly increases arc starts rotate. The force pressure directed forward side edges weld pool then appear. This results movement liquid metal front part crater edges, formation welded joints without undercutting, undercutting one-sided high-speed welding. A...
The results of investigations the effect amount and composition exothermic mixture in filler powder strips, produced with different rolling parameters, on melting parameters transition alloying elements from strip to deposited metal are presented.
The results of investigations the effect chemical composition flux used for flux-cored wire surfacing to produce metastable austenite in deposited metal are presented.

At casting of steel on CCM quality all ingots is almost identical by creating stable conditions continuous casting. The fi nal slabs have a defect in the form cross-sectional dimensions - deviation from desired values. This leads to additional losses metal subsequent metallurgical redistribution and reduces cost commodity products. prior studies publications consider technology established periods. Transition periods been poorly studied because there are no simple reliable methods...
Gas-slag-forming systems of flux-cored wires for plasma building-up welding surveyed. Application substances at overlaying boron triphtoride is considered, to provide the improvement formation deposited bead, reduces vaporization. Systems gas-slag-forming which are gating out proposed excreting investigated welding.
Possibility of increase the productivity is investigational at welding copper with steel by optimization components powder-like wire. Practical researches are executed. The mathematical model process created. Optimization composition wire executed
Two alloying systems of stamping tools (with intermetallic and carbide hardening) are analysed. Analysis shows the high characteristics metal with different systems. The heat resistance 100Kh4M5F2(Zr) alloy is not inferior to R18 high-speed tool steel, hardness equals 58–62 HRC as a result hardening. relative wear 8Kh4GSV2M5F2T was (ε = 2.65), impact toughness (0.28 MJ/m2) (55 HRC). highest recorded for K15M15N5Kh3B2 following properties after treatment: (0.1 (39 2–2.5 times higher than that...
