Product Description

The raw material is stainless steel ingots, using electric stoves which melt the stainless steel ingots to become 1500 ~ 1600 ºC steel liquid, and then with a grooved high speed rotating melt-extracting steel wheel which produces wires that meets specific requirements. The liquid steel blow out by slot with centrifugal force at extremely high speed with cooling forming. Melting wheels with water keep the cooling speed to produce different materials and sizes of steel fiber.
