The invention relates to a slag grabbing hopper protective cover and a slag grabbing method for buffering water flow impact force of a rotational flow well, and belongs to the technical field of metal rolling equipment in the metallurgical industry. According to the technical scheme, the protective cover comprises a protective cover body (1), rails (3), flanges (4), supporting beams (5) and throttling holes (7), the protective cover body (1) is of a circular structure matched with the slag grabbing hopper (11), the throttling holes (7) are formed in the protective cover body (1), the rails (3) are arranged on the inner wall of the protective cover body (1) in the circumferential direction, one ends of the two supporting beams (5) are connected to the rails (3) in a sliding mode, and the other ends of the two supporting beams (5) are connected to the flanges (4) in a sliding mode. And the other ends of the two supporting beams (5) are respectively provided with a connecting flange (4) matched with the slag grabbing hopper (11). The slag grabbing bucket has the beneficial effects that the impact force of water flow of the rotational flow well can be effectively reduced, rotation of the slag grabbing bucket is relieved or eliminated, the situation that the slag grabbing bucket collides with the well wall is avoided, and the slag grabbing efficiency is improved.

    本发明涉及一种抓渣斗防护罩及缓冲旋流井水流冲击力的抓渣方法,属于冶金行业金属轧制设备技术领域。技术方案是:包含防护罩罩体(1)、轨道(3)、法兰(4)、支撑梁(5)和节流孔(7),所述防护罩罩体(1)为与抓渣斗(11)相配合的圆环形结构,防护罩罩体(1)上设有若干个节流孔(7),防护罩罩体(1)的内壁圆周方向上设有轨道(3),两个支撑梁(5)的一端分别滑动连接在轨道(3)上,两个支撑梁(5)的另一端分别设有与抓渣斗(11)相配合的连接法兰(4)。本发明的有益效果是:能够有效的降低旋流井水流的冲击力,减缓或消除抓渣斗的旋转,避免撞击井壁,提升抓渣效率。
