    • PURPOSE: A manufacturing method of iron-based powder using converter molten steel is provided to reduce manufacturing costs of iron-based powder by manufacturing a large amount of powder-based steel all at once by using a converter. CONSTITUTION: A manufacturing method of iron-based powder using converter molten steel is composed of the following steps. Molten iron which is made through a steel manufacturing process is made into molten steel by blowing the molten steel(S10). The molten steel is treated with rephosphorization prevention in a converter, and continuously tapped from the converter into multiple ladles at the same time(S20). The molten steel is supplied to each tundish corresponding each of the ladles(S30). The iron-based powder is manufactured by spraying high pressure water onto the molten steel which is discharged through a nozzle on the tundish(S40). [Reference numerals] (S10) Manufacture molten steel in a converter; (S20) Treat the molten steel for preventing rephosphorization and tap the molten steel into multiple ladles; (S30) Supply the molten steel to a tundish with a nozzle; (S40) Manufacture iron-based powder by discharge through the nozzle
    • 目的:提供一种使用转炉钢铁的铁基粉末的制造方法,通过使用转炉,一次制造大量的粉末状钢来降低铁基粉末的制造成本。 构成:使用转炉钢水的铁基粉末的制造方法由以下步骤组成。 通过钢水制造工艺制造的熔融铁通过吹制钢水而制成钢水(S10)。 在转炉中对钢水进行再防磷处理,同时连续从转炉中抽出多个钢桶(S20)。 将钢水供应到每个浇包对应的每个中间包(S30)。 通过将高压水喷射到通过中间包上的喷嘴排出的钢水上来制造铁基粉末(S40)。 (S10)在转炉中制造钢水 (S20)处理钢水,防止再次磷化,并将钢水分解成多个钢桶; (S30)用喷嘴将钢水供给中间包; (S40)通过喷嘴排出制造铁基粉末
