Medium Temperature Trolley Furnace


Introduction :

1 Feeding and discharging are fast


2 The inverted structure is more effective


3 The energy saving is 30% less than that of the common trolley type resistance furnace


Application :

For large and medium sized carbon steel, alloy steel parts in oxidizing atmosphere of normalizing, annealing, quenching and stainless steel parts solid solution treatment
