Foundry Grade Pure Iron 99.8% Supplier | Low Carbon Masterbatch for Steelmaking
Product Overview
Beilun Metal supplies pure iron (Fe ≥ 99.8%) as furnace material, specially designed for electric arc furnace (EAF) and induction furnace steelmaking. As a low-carbon base material, it can accurately control the composition of molten steel, significantly reduce sulfur and phosphorus residues (S ≤ 0.005%, P ≤ 0.006%), and improve the purity and mechanical properties of special steels such as silicon steel and stainless steel. Supports block shaped (10-50mm), granular (1-5mm), and customized forms, in compliance with ASTM A848 and JIS G2305 furnace charge standards.

The three major steelmaking functions of pure iron in furnace materials
1. Pure substrate:
Replace scrap steel to avoid residual element pollution such as copper and tin (control Cu ≤ 0.002%)
Case: After using our pure iron in a domestic stainless steel factory, the absorption rate of nickel chromium alloy increased by 12% and the amount of slag decreased by 18%
2. Ingredient adjustment:
Quickly reduce the carbon content of molten steel (adding 0.03% -0.05% C per ton can reduce it)
Case: A Japanese tool steel plant stabilized the quenching hardness of SKD11 mold steel to 62 ± 1 HRC by adding Beilun pure iron
3. Deoxygenation efficiency enhancement:
Combined with aluminum/silicon calcium wire, deoxidation time is reduced by 20% (compared to traditional scrap steel)
Why choose Beilun furnace material pure iron?
High consistency: Melting is carried out using a vacuum induction furnace (VIM), with component fluctuations of ≤± 0.01% per batch
Rapid melting: optimized grain size (ASTM No.5-7), melting speed 15% faster than ordinary pure iron
Global delivery: Provides moisture-proof vacuum packaging, supports EXW/FOB/DDP terms
Certification guarantee: MSDS report+SGS RoHS compliance certificate
Industry application scenarios
Stainless steel smelting: 304/316L base material, controlling chromium nickel oxidation loss
Electrical steel production: reducing iron loss (W15/50 ≤ 2.3W/kg)
Special alloys: oxygen sensitive melting of titanium alloys/high-temperature alloys
Automotive plate steel: IF steel with ultra-low carbon (C ≤ 0.003%) stabilization treatment
Technical comparison: Furnace charge pure iron vs traditional scrap steel

FAQ
Q： How to calculate the proportion of pure iron added to the furnace charge?
A： Based on the carbon content requirements of the target steel grade, the recommended formula is:
Addition amount (kg)=(Initial C% - Target C%) x Steel weight (ton)/Pure iron C%
Q： Do you support small batch samples?
A： Provide 50kg free samples with recommended melting parameters report.
Q： How to avoid transportation oxidation?
A： Nitrogen filling packaging is used, with an increase in oxygen content of ≤ 5ppm upon arrival at the port.
