如何正確的選用螺旋卸車機的耐磨材料
時間 : 2019-09-15 21:29 瀏覽量 : 28


在一些碼頭和水泥廠這些大型生產的地方,經常會用到螺旋卸車機,這種機器能幫助裝卸煤渣、礦石等材料。螺旋卸車機總的分為橋式和門式,但是如今的生產率是越來越高,人們由此又是在這基礎上又有了新的機器,新的機器利用到了導桿的作用。簡單來說卸車機就是合適的用到螺旋,用它的升降力讓東西進行裝卸??墒窃跈C器工作的途中,總會對其造成很多的磨損,選擇一些合適的材料是非常必要的,會讓內部零件的壽命更長,減少停機的幾率,那么下面就來看一看合適的耐磨材料。

如何正確的選用螺旋卸車機的耐磨材料

 


1.Fe-Cr-B焊條


這種焊條使用手工電弧焊來完成的,因為這種材料里面含有Cr和B這兩種元素,并且有較高的碳含量,所以它的組織大部分都是硼化物組,因此它的硬度非常的高,在堆焊層的耐磨性也是同樣的上去了。這種焊條在使用的時候特點也是非常明顯,最主要的是操作非常的簡單,對于工人們的勞動強度降低了很多,環境同樣也是會好很多,并且堆焊的平整度也會上去,如果后面磨壞的話,修補之后對平整度的適應性也很好。


 


2.kb899焊絲


這種焊絲采用氣保焊的方法,使用的金屬是碳化鎢合金,同樣也是硬度非常的高,達到了68HRC,它是最耐磨的一種焊絲,耐磨性超過了鐵的三倍,這還是非常值得驕傲的。和其他的材料比起來,它的停機率也是非常低的,這讓效率提升了非常多。
