摘要
高炉炉顶布料溜槽长期受到硬度较高、速度较大的冶炼料流的冲刷,磨损严重,属于耗损件。为提高溜槽衬板的使用寿命,采用WC作为耐磨层的基体,用锰白铜作为钎料,通过浸润焊接方式,在衬板基材上钎焊上一层硬质合金。实际使用表明,与堆焊硬质合金相比,焊接质量更好,不易开裂和脱落,可以延长设备使用寿命1年以上,具有较好的经济价值。
The spreading iron material chute on the blast furnace enduringly was scoured by higher hardness and higher speed＇s melting material flow,and the wear mass loss is serious,so the chute is easily damaged parts.To improve the life of the chute liner,WC is used as a wear-resistant layer matrix,BMn3-12 is used as filler,by infiltration welding,the brazing layer formed on the liner＇s base metal.Compared with the surfacing alloy,the infiltration welding quality is better,the welded joint is not easy to crack and fall off,the useful life of the equipment can be extended more than 1 year,with better economic value.
