摘要
钢坯除磷不净易引起钢轨表面缺陷,影响钢轨正常使用,为提升钢坯除磷效果,提出钢坯高压水除磷喷嘴设计策略.通过了解钢轨除磷现状,明确除磷问题,计算喷嘴喷射参数,建立喷嘴模型进行模拟与分析.研究认为:喷嘴入流速度v=200 m/s,喷嘴出流直径D=6 mm,喷嘴出流角度θ=11°,钢坯原始温度t1=1240 ℃,水温t2=20 ℃,该工艺条件的钢坯高压水除磷具有清理全面、高效的特点,经验证,提出的钢坯高压水喷嘴设计方案应用效果良好,对工业生产有指导意义.
Abstract
Poor phosphorus removal from steel billets can easily cause surface defects on rails,affecting their normal use.In order to improve the phosphorus removal effect of steel billets,a design strategy for high-pressure water phosphorus removal nozzles for steel billets is proposed.By understanding the current situation of phosphorus removal on steel rails,clarifying the problem of phosphorus removal,calculating nozzle spraying parameters,and establishing a nozzle model for simulation and analysis.Research suggests that the inlet velocity of the nozzle is v=200 m/s,the outlet diameter of the nozzle is D=6 mm,the outlet angle of the nozzle is θ=11 °,the original temperature of the steel billet is t1=240 ℃,and the water temperature is t2=20 ℃.The high-pressure water phosphorus removal of the steel billet under this process condition has the characteristics of comprehensive and efficient cleaning.After verification,the proposed design scheme for the high-pressure water nozzle of the steel billet has good application effect and has guiding significance for industrial production.
