摘要:本实用新型公开了一种转炉用均质挡渣锥,由圆台状的锥体和导向杆组成,所述锥体倒置成上大下小的形状,在锥体的中心线上设置有中心孔,中心孔在锥体内形成通孔,导向杆贯穿于中心孔且上下两端均伸出锥体外,在锥体上端开口处设置有挡块,通过焊接挡块将导向杆固定在锥体上,在导向杆的下部套有耐火层,在锥体的侧面上设置有至少三条沟槽。本实用新型的挡渣锥能够确保挡渣率,提高钢质量;采用了导向杆的结构,同时抑制出钢口上方涡流的形成,减少钢渣随涡流被吸入钢包内的几率;结构简单,制作方便,成本低,便于大规模生产和使用。

主权项:1、一种转炉用均质挡渣锥,包括圆台状的锥体(1)和导向杆(2),其特征在于:所述锥体(1)倒置成上大下小的形状,在锥体(1)的中心线上设置有中心孔(5),导向杆(2)贯穿于中心孔(5)且上下两端均伸出锥体(1)外,在锥体(1)上端中心孔(5)处设置有挡块(3),挡块(3)将导向杆(2)固定在锥体(1)上,在导向杆(2)的下部设置有耐火层(4),在锥体(1)的侧面上设置有至少三条沟槽(6)。
