Thermal cutting

XAR400耐磨鋼板火焰切割加工

 Preferably the flame-cutting process is used. For small product thicknesses, however, the plasma cutting process is used in the interest of minimum distortion.

Preheating is not normally necessary when flame-cutting thicknesses up to around 30 mm (1.181 in.). However, if the workpiece temperature is below + 5 °C (+ 41 °F), or the cut edges are to be cold-formed in the course of further processing, preheating to about 150 °C (302 °F) should be considered in the interest of cold cracking resistance.

XAR400耐磨鋼板最好用等離子切割或者激光切割，然而，對(duì)于較厚的鋼板，超過了等離子切割的厚度范圍， 可以選用火焰切割切加工割。

XAR400耐磨鋼板火焰切割加工厚度不大于30毫米的鋼板時(shí)，一般情況下，不需要預(yù)熱處理。 然而當(dāng)被加工件溫度低于+ 5 °C 時(shí)

，或者切割邊在接下來(lái)的加工程序需要冷成形加工，則預(yù)熱 150 °C 是需要考慮的以避免冷裂發(fā)生。
