耐磨板400的火焰切割和等离子切割优劣对比

HARDOX400400耐磨板是一种热处理钢板,和市面上的大部分耐磨钢板,受热到一定温度,大约300度以上时,硬度就会快速下降。所以切割时,耐磨板尽量使用冷切割,否则会产生切割出硬度下降的问题。

Hardox400 wear-resistant plate is a kind of heat-treated steel plate, and most of the wear-resistant steel plates on the market, when heated to a certain temperature, about 300 degrees above, the hardness will drop rapidly. Therefore, when cutting, the wear-resistant plate should be cold cut as far as possible, otherwise the hardness will decrease.

Hardox400耐磨板属于热处理调质钢板,所以现在切割时候大多已经使用等离子切割或其他切割方式。火焰切割是用高温氧气切割耐磨板,所以火焰切割加工会对耐磨板产生热影响区,现在还在使用火焰切割的Hardox400耐磨板,一般都是使用时对切割处硬度要求不高,可以忽略硬度下降的问题。因为火焰切割可以共边切割,节省材料。

Hardox400 wear-resistant plate belongs to heat-treated quenched and tempered steel plate, so plasma cutting or other cutting methods have been used in cutting. Flame cutting is to use high temperature oxygen to cut the wear-resistant plate, so flame cutting processing will produce heat affected zone on the wear-resistant plate. Now the Hardox400 wear-resistant plate is still using flame cutting. Generally, the hardness requirement of the cutting place is not high, and the problem of hardness decline can be ignored. Because the flame cutting can be co edge cutting, saving materials.

切割费用也比较低。从经验的角度来说,Hardox400耐磨板加工没有热影响区的只有水刀切割和线切割加工,但其实因为价格原因使用这两种切割的耐磨板并不多。激光切割加工悍达耐磨板次之,等离子切割的热影响区也比较小,但是因为切割时候切口是倾斜的,所以会浪费一些材料。

Cutting costs are also relatively low. From an empirical point of view, Hardox400 wear-resistant plate processing has no heat affected zone, only water knife cutting and wire cutting processing, but in fact because of the price reason, the use of these two kinds of cutting wear-resistant plate is not much. Laser cutting processing of harda wear-resistant plate takes the second place, plasma cutting heat affected zone is also relatively small, but because the cutting incision is inclined, so it will waste some materials.

如果厚度大于50mm或者加工条件有限,在耐磨板产品设计的时候就应当考虑到这个问题,也可以用加工的方式去除掉热影响区。另外如果是低于40mm的耐磨板,基本都要避免使用火焰切割,一面带来热变形,把耐磨板浪费掉,尤其是低于10mm厚度的耐磨板,火焰切割的影响已经会非常大。

If the thickness is greater than 50 mm or the processing conditions are limited, this problem should be considered in the design of wear-resistant plate, and the heat affected zone can also be removed by processing. In addition, if the wear-resistant plate is less than 40mm, the flame cutting should be avoided. On the one hand, it will bring thermal deformation and waste the wear-resistant plate, especially for the wear-resistant plate with thickness less than 10mm, the impact of flame cutting will be very large.
