Description
Technical field
The invention belongs to the welding fields in Materials Processing Engineering, and in particular to a kind of ilmenite type E308 flux-cored wire.
Background technique
Flux-cored wire is a kind of novel welding material developed rapidly in recent years, production good with welding quality
The series of advantages such as high-efficient, comprehensive welding cost is low, in shipbuilding, machinery, petrochemical industry, metallurgy, military project, manufacture of steel structure and engineering
It is widely applied in construction.Stainless flux-cored wire at present, the medicine core formula of the type flux-cored wire typically constitute from medicine based on rutile
30% or so of core, used raw material are natural rutiles, wherein TiO2Content it is general >=95%.However natural rutile
Mineral resources are rare, and distributed pole is uneven on earth, mainly produce at present a small number of in Australia, South Africa, Ukraine
Several countries.It is increasingly depleted recently as world's natural rutile placer mining, and market is to high-grade natural rutile
Demand is continuously increased, so that the rapid rise of price of high-grade natural rutile, price rising over the past two years nearly 200%, and artificial gold
Red stone is by resource constraint, and complex process, yield very little and pollutes the environment, and price also differs nothing with natural rutile
It is several.
