OKAYAMA GIKEN (Mining) Co., LTD.,is a reliable Steel Fibers For Refractory manufacturer and exporter based in China, with years of experience supplying high-performance reinforcement fibers for the refractory industry.We manufacture and export steel fibers tailored for steel plants, cement kilns, ladles, tundishes, incinerators, and other high-temperature environments.
At OKG，Our high-quality steel fibers for refractory applications are designed to reinforce refractory castables under extreme thermal and mechanical stress,improve the cracking resistance and thermal shock durability of your castable refractories.
· High Tensile Strength: ≥1100 MPa
Strong resistance to thermal cracking and mechanical damage.
· Optimized Length & Diameter:
Standard size: 25mm length × 0. 5mm diameter, or customized as per your formula.
· Uniform Dispersion:
Excellent workability in castables – no clumping, even mixing.
· Improved Lining Life:
Reduces spalling, extends refractory lining service time by 30–50%.
· Cost-Effective:
Direct factory price and flexible packing (bulk bags, water-soluble bags).
● Our steel fibers are widely used in:
● Electric Arc Furnace (EAF) walls and roofs
● Steel ladle & tundish lining castables
● Precast refractory blocks
● Cement rotary kiln linings
● Garbage incinerator lining
● Boilers and industrial furnaces
● They significantly reduce crack formation caused by heat shock and mechanical stress.
