So far forever has already had many sucessful cases for long bar heat treatment machine, such as ¸20 long bar heat treatment machine, ¸40 long bar heat treatment machine, ¸60 long bar heat treatment machine, ¸90 long bar heat treatment machine etc. Long bar heat treatment machine features 1.Brand: forever 2.Power: 100-8000kw 3.Material: bar, pipe, rod, plate, tube 4.Heating temperature:900-950 degree c. 5.Heating way: magnetic induction heating 6.Process: quenching, tempering Long bar heat treatment machine advantages 1. uniform heating: the angle between roller axis and bars axis is 18 ~ 21 °. The long bar is rotating by itself and go forward at the uniform rate for uniform heating. Rollers between furnace are 304 non-magnetic stainless steel and water-cooled. 2.Uniform cooling:to meet the requirements of different hardenability, spraying system adopts multi-level spray cooling and the pressure & flow in water spray ring at all levels is adjustable.The long bar will be placed in the middle of spray ring to ensure uniform pressure and flow. 3. closed-loop temperature control system: our engineer will set the process parameters in the system, and when the heating temperature is too high or too low, the system will adjust the temperature to the required temperature through adjusting power. Main parts introduction 1.Germany siemens igbt module. 2.Electrolytic capacitor. ( filter capacitor ) 3.Imported transistor integrated block. 4.All water pipe use thermostability, high pressure resistance best quality material. 5main card, signal circuit, drive circuit board, control circuit board and components are adopted. 6.International advanced all-solid-state semiconductor power devices.
