Pit gas carburizing furnace resistance furnace cycle mode of operation is to drip controllable carburizing, carbonitriding, multicomponent permeation, gas soft nitriding heat treatment process designed for multi-purpose chemical heat treatment furnaces. Drop control carburizing atmosphere is generated in accordance with the different uses, select one or more different organic liquids, according to a certain proportion, by the liquid flow meter and manual precision Droppers to drip after the furnace at a high temperature to form a lysate a.
