Description

Name:碳化钨焊条硬质合金焊条YZ220-30焊条
Commodity number :NO31792

    1. 铸造碳化钨焊条同耐磨堆焊焊条属同类,是近几年新开发的超硬,超耐磨材料.耐磨度超过耐磨焊条的几倍,是修复深井钻头的必用品.

    2. 采用气焊焊接有较高的耐磨性和耐冲击性。

    3.此焊条是含钨粉,硼粉及合金粉末组成的高耐磨气焊条,硬度高、耐磨、耐冲击、耐高温。

    4. 氧-乙炔温度:1000~2800度.含钨量为65%-85%,粒度:30目-80目 .

    5. 广泛应用于石油钻具,工程机械,螺旋推进器(绞龙)叶片、排风机叶轮,搅拌机叶片,泥浆泵、煤矿溜槽等的堆焊,粉碎机叶片,矿业机械,煤炭钻杆,榨糖蔗刀等.硬度高,抗岩石砂磨粒磨损。延长设备寿命6-7倍. HB≥80

    1、碳化钨焊条,用氧-乙炔堆焊,多采用碳化焰,施焊温度控制在1700℃,被堆焊工件必须预热,堆焊面局部部加热850℃-950℃再施焊。                        

    2、应知堆焊工件的材质,不同的材质选用不同的焊条才能得到满意的效果。 

    3、堆焊工件,应除去铁锈、杂质、油污。
