本发明属于转炉炼钢工艺技术领域，具体涉及一种采用少渣料冶炼高磷铁水生产转炉终点P≤0.01％钢的方法。所述方法为：向转炉中装入未经三脱预处理的低硅高磷铁水和废钢，采用单渣法操作进行吹炼，在吹炼过程中分两次加入造渣料，并且在吹炼过程中采用高‑低‑高‑低的枪位控制模式，在吹炼过程中供氧供氮；吹炼结束后出钢，出钢后进行溅渣，溅渣后留渣用于下一炉的冶炼。本发明所述方法在控制石灰消耗≤30kg/t钢液，新渣料消耗≤50kg/t钢液的前提下，可将元素重量百分比为Si：0.14‑0.26％、P：0.15‑0.20％的铁水脱磷至P≤0.01％，脱磷率≥94％，解决了低硅高磷铁水少渣料单渣法冶炼低磷钢的难题。

The invention belongs to the field of steelmaking by converter technology and specifically relates to a method for producing converter endpoint P ≤ 0.01 % steel by smelting high phosphorus hot metal with less slag. The method described is as follows: low silicon and high phosphorus hot metal and scrap without three de-treatment are loaded into the converter, and the single slag method is used for blowing. The slagging material is added twice in the blowing process, and the lance control mode of high-low-high-low is used in the blowing process to supply oxygen and nitrogen in the blowing process. After blowing, the steel is discharged, and slag splashing is carried out after tapping. After slag splashing, the slag is retained for smelting in the next furnace. On the premise of controlling lime consumption ≤ 30 kg/t molten steel and new slag consumption ≤50 kg/t molten steel, the method can dephosphorize molten iron with Si: 0.14~0.26%, P: 0.15~0.20% to P ≤0.01% and dephosphorize rate ≥94%, which solves the problem of smelting low phosphorus steel by single slag method with low silicon and high phosphorus molten iron and few slag.
