Hardness Of Steel Fibers

No matter which processing method is used, steel fibers will encounter high heat and rapid cooling during processing, which is equivalent to a quenching state. Therefore, the surface hardness of steel fibers is relatively high. When used for concrete reinforcement and mixing, bending rarely occurs. If the steel fiber is too hard and brittle, it will easily break during mixing, which will affect the reinforcement effect. When producing steel fibers by the melting and extraction method, the steel fibers centrifugally ejected from the melting and extraction wheel are still in a high temperature state and must be dispersed and cooled by rollers or vibration conveying methods. Otherwise, the steel fibers will gather and the heat will be difficult to dissipate, which will act as an annealing effect.
