The invention discloses a device and a method for quickly replacing a tuyere medium sleeve, and belongs to the technical field of metallurgical equipment maintenance. The device comprises a clamping hook, a push-pull rod, a sliding hammer and a lifting hook, the clamping hook comprises a hook head part, a hook tail part and a telescopic part, the hook head part and the hook tail part are arranged at the two ends of the telescopic part to form a clamping groove matched with the middle sleeve, and the hook tail part is detachably connected with the push-pull rod; the sliding hammer is sleeved on the push-pull rod and is fixed with the push-pull rod through a bolt; and the lifting hook is detachably connected with the push-pull rod. According to the method, the characteristic that expansion and shrinkage are generated after the middle sleeve is rapidly heated and rapidly cooled on site can be fully utilized, a gap is generated between the middle sleeve and the large sleeve of the tuyere, the middle sleeve can be rapidly pulled out to be replaced by being matched with the replacement device, and the obvious effects are achieved on environment-friendly treatment on the working site, reduction of the labor intensity of workers and production safety.

    本发明公开了一种快速更换风口中套的装置和方法,属于冶金设备维护技术领域。该装置包括卡钩、推拉杆、滑锤和吊钩,卡钩包括钩头部、钩尾部和伸缩部,钩头部与钩尾部设于伸缩部的两端,形成与中套相匹配的卡槽,钩尾部可拆卸地连接推拉杆;滑锤套设于推拉杆上,并与推拉杆通过螺栓固定;吊钩与推拉杆可拆卸连接。本发明可以充分利用现场对中套进行急热急冷后产生的膨胀收缩的特点,使风口中套与大套产生间隙,配合更换装置的使用能够使中套被快速拉出进行更换,对于工作现场的环保治理、工人劳动强度的降低和生产的安全性均有显著效果。
