耐磨钢板切割开孔焊接等加工注意事项

所属分类:行业资讯 发布时间:2021-02-26 17:07:08 来源:http://www.lcnmb500.com 浏览量:

在现代工业上耐磨钢板显然已经成为不可缺少的耐磨材料,不仅可以解决磨损快,耗费量大与耽误工期等问题,而且也响应了国家控量减排,减少污染的可持续发展战略,在环保方面做出了巨大的贡献。

In modern industry, wear-resistant steel plate has obviously become an indispensable wear-resistant material, which can not only solve the problems of fast wear, large consumption and delay of construction period, but also respond to the national sustainable development strategy of quantity control, emission reduction and pollution reduction, and make great contributions to environmental protection.

HARDOX600耐磨钢板是一种特种钢板,因此需要了解钢板的切割打孔焊接等特性,下面具体介绍一下:

Hardox600 wear resistant steel plate is a kind of special steel plate, so it is necessary to understand the cutting, drilling, welding and other characteristics of steel plate

耐磨钢板切割开孔焊接等加工注意事项(图1)

1.切割:可用等离子切割、碳弧、砂轮锯将大面积复层钢板切割成所需要的形状。方法是用空气或者惰性气体等离子弧进行切割,推荐方法是从合金面开始切割。碳弧切割应从基板一面开始切割。如果采用锯片,只能进行直线切割,需要采用碳化硅锯片。

1. Cutting: plasma cutting, carbon arc cutting and grinding wheel saw can be used to cut large area clad steel plate into required shape. The recommended method is to start cutting from the alloy surface. Carbon arc cutting shall start from one side of the substrate. If the saw blade is used, it can only be cut in a straight line, and silicon carbide saw blade is needed.

2.弯曲:耐磨钢板可以进行冷加工成型,根据需要弯曲成所需要的形状,或弧或圆。凹面成型,合金裂纹由于向内应力将紧闭;凸向成型,裂纹将变大开裂,这是正常现场。如果开裂过大,使用相应焊条进行修补。卷曲成管,按推荐最小弯曲半径进行。

2. Bending: the wear-resistant steel plate can be formed by cold working, and it can be bent to the required shape, or arc or circle. In concave forming, the alloy cracks will be closed due to the internal stress; in convex forming, the cracks will become larger and crack, which is the normal site. If the crack is too large, use the corresponding welding rod for repair. Crimp the tube according to the recommended minimum bending radius.

3.开孔:大孔可以采用等离子切割,小孔推荐使用电火花机床。装配螺栓用的沉头孔可以用等离子或者碳弧切割加工。

3. Opening: plasma cutting can be used for large holes, and EDM is recommended for small holes. The countersunk holes for assembling bolts can be machined by plasma or carbon arc cutting.

4.焊接:大面积耐磨复合钢板的母材是可焊接性能很好的钢板,需要两块钢板拼接时,可先将背面母材焊接在一起,然后用相应的堆焊焊条将正面堆焊层填平补齐。耐磨钢板也可以焊接到其他钢结构上。

4. Welding: the base metal of large area wear-resistant composite steel plate is a steel plate with good weldability. When two steel plates need to be spliced, the back base metal can be welded together first, and then the front surfacing layer can be filled up with corresponding surfacing electrode. Wear resistant steel plates can also be welded to other steel structures.

5.塞焊:可用等离子或者碳弧气刨在耐磨钢板上开孔,通过塞焊的方法与其他钢结构件连接。

5. Plug welding: plasma or carbon arc gouging can be used to open holes on the wear-resistant steel plate, and plug welding can be used to connect with other steel structures.

6.螺栓固定:可以用闪光焊或者融化焊的方法将螺栓焊接到钢板的母材上,然后与其他工件连接,也可以在耐磨钢板上开孔,通过螺栓与其他工件连接;

6. Bolt fixation: the bolt can be welded to the base metal of the steel plate by flash welding or melt welding, and then connected with other workpieces, or the hole can be opened on the wear-resistant steel plate to connect with other workpieces by bolts;

7.表面加工:耐磨钢板表明无须加工,如果需要加工,只能是研磨,其他常规方法不适用。耐磨钢板不适用表面精度要求高的场合。

7. Surface processing: wear resistant steel plate indicates that it does not need to be processed. If it needs to be processed, it can only be ground. Other conventional methods are not applicable. Wear resistant steel plate is not suitable for the occasion of high surface accuracy requirements.
