Inline Automatic High Temperature Steel Dot Peen Marking Machine for Heavy Red Hot Highspeed Rails Wheels Steel Rods Bars Stamping Engraver   High temperature Dot Peen Marking Machine is usually suitable for high-specification special steel products, such as high-speed rail tracks, wheels, and some ultra-high hardness steel bars. Such steel needs to be marked at a red high temperature of 600 degrees Celsius or higher and then directly quenched or annealed. Otherwise, the hardness after hardening is as high as HRC65 or above, which makes it difficult to use conventional pneumatic Dot Peen Marking Machine or Scribe Machine for marking. At the same time, such steel parts usually need to be cooled naturally after multiple strengthening. Due to the high internal temperature, the use of high-power laser marking will cause the steel strength to change or even crack due to the influence of the hot zone. The high-temperature marking machine solution is specially designed to solve the instant m…
