Welding Consumables Metal Materials reduced iron powder FHT40.30, FHT40.37, FHT100.25

製品特性：...The reduction process is divided into (solid carbon reduction) primary reduction and secondary reduction. The primary reduction is the production of sponge iron by solid carbon reduction. The main process of primary reduction is: (iron concentrate, rolled steel scales, etc.) → drying → magnetic separation → crushing → screening → canning → entering the primary reduction furnace → sponge iron. Secondary precision reduction process: Sponge iron → Cleaning → Crushing → Magnetic separation → Secondary reduction furnace → Powder block → Crushing → Magnetic separation → Screening → Grading → Mixing → Packaging → Finished product.
