堆焊复合耐磨板焊丝分类及选择

所属分类:常见问题 发布时间:2021-04-26 来源:https://www.lcnaimoban.com/ 浏览量:

堆焊复合耐磨板就是以普通钢板为基材,在其表面堆焊一层碳化铬,使钢板具有更高的强度,所以堆焊耐磨板的质量,主要是由焊丝和堆焊工艺来决定的。耐磨焊丝有很多详细的分类。
Hardfacing composite wear-resistant plate is based on ordinary steel plate. A layer of chromium carbide is overlaid on its surface to make the steel plate have higher strength. Therefore, the quality of hardfacing wear-resistant plate is mainly determined by welding wire and hardfacing process. There are many detailed classifications of wear-resistant welding wires.
首先可以分为单层焊丝,双层焊丝和多层焊丝。从使用类别上又可以分为各种修复焊丝和气体保护焊丝。优质的焊丝有具备送丝流畅,电弧稳定,直径均匀。焊丝飞溅小,烟尘小,熔敷效率要高。优质的焊丝基本每一包焊丝是一根整根的焊丝,没有接缝。复合以上特点的焊丝为优质焊丝。

Firstly, it can be divided into single layer welding wire, double layer welding wire and multi-layer welding wire. From the use of categories can be divided into a variety of repair wire and gas shielded wire. High quality welding wire has smooth wire feeding, stable arc and uniform diameter. The spatter of welding wire is small, the dust is small, and the deposition efficiency is high. High quality welding wire basically every package of welding wire is a whole welding wire without seam. The welding wire with the above characteristics is of high quality.
焊丝按粗细来分,主要有几种种规格,1.2mm,1.6mm,2.4mm,2.8mm和3.2mm,不同规格的焊丝具备不同的硬度,优质的焊丝硬度要能达到HRC55以上,越高越好。碳和铬的含量决定了焊丝的硬度,基本焊丝的碳含量在3.0-5.0左右,铬含量在15-40之间。优质的焊丝堆焊后,其表面的对焊层要有较好的抗冲击性,不易脱落。焊丝根据不同的行业还可以有更加详细的细分,譬如有的厂家,焊丝可以针对不同使用机械,细分为水泥立磨堆焊焊丝,轧辊堆焊焊丝,挤压辊堆焊焊丝,星轮修复焊丝等具体分类。
According to the thickness of welding wire, there are several specifications, 1.2mm, 1.6mm, 2.4mm, 2.8mm and 3.2mm. Different specifications of welding wire have different hardness. The hardness of high-quality welding wire should reach above HRC55, the higher the better. The content of carbon and chromium determines the hardness of welding wire. The carbon content of basic welding wire is about 3.0-5.0, and the chromium content is between 15-40. After surfacing with high quality welding wire, the butt welding layer on the surface should have good impact resistance and not easy to fall off. According to different industries, welding wires can be subdivided in more detail. For example, for some manufacturers, welding wires can be subdivided into cement vertical mill surfacing welding wire, roller surfacing welding wire, extrusion roller surfacing welding wire, star wheel repair welding wire, etc.
而气体保护焊丝也可以细分为耐冲击焊丝,耐高温焊丝,气保修复焊丝,以及含各种特殊元素的焊丝等。
The gas shielded welding wire can also be divided into impact resistant welding wire, high temperature resistant welding wire, gas shielded repair welding wire, and welding wire containing various special elements.
堆焊耐磨板的生产中,焊板平台是非常重要的。现在先进的焊板平台都是全自动多头平台,多头平台比单头平台焊接效率更高,堆焊的耐磨板对焊层不易脱落,平板弯曲大。而且新型的焊板平台都有较高的自动化水平,可以控制每一只焊枪的启停,高度,可以实现断点续焊功能。焊接出来的双金属复合耐磨板要表面硬度均匀,板面平整,裂纹细微的特点。
In the production of hardfacing wear-resistant plate, the welding plate platform is very important. At present, the advanced welding plate platforms are all full-automatic multi head platforms. The welding efficiency of multi head platform is higher than that of single head platform. The butt welding layer of hardfacing wear-resistant plate is not easy to fall off, and the plate bending is large. Moreover, the new type of welding plate platform has a high level of automation, which can control the start, stop and height of each welding gun, and realize the function of breakpoint welding. The welded bimetal composite wear-resistant plate should have the characteristics of uniform surface hardness, flat surface and fine cracks.
另外堆焊工艺不仅可以生产双金属耐磨板,现在还可以使用耐磨管堆焊设备,在钢管内进行堆焊,生产出来堆焊耐磨板。
In addition, the surfacing process can not only produce bimetallic wear-resistant plate, but also use the surfacing equipment of wear-resistant pipe to carry out surfacing in the steel pipe to produce the surfacing wear-resistant plate.
