The gas fired bogie hearth furnace is mainly used for heat treatment of metal parts. The furnace works
with gas so as to save overall running cost.
High Quality Variable Capacity Gas Type Bogie Hearth Furnace is state standard energy saving cyclic
furnace. It is a fiber structure saving 60% power consumption. This series furnace is applicable to
the quenching, annealing and aging treatment of high chrome parts, high manganese cast parts, cast iron,
rolls, steel balls, 45# steel parts and others.
