FD furnaces are used to prevent surface oxidation on items during annealing operations and to deoxidise finished products. They ensure uniform thermal treatments. Thanks to the use of a protective gas, the items come out deoxidised and bright.
A stainless steel water tank for rapid cooling operations is also included; by means of a manually operated or automatic lifting device.
The furnace is also fitted with a patented cooling chamber, entirely built in stainless steel, which prevents condensate from dripping onto the items during the treatment.
An electronic timer counts down the deoxidation time only after the metal inside as reached the preset temperature.
The muffle is made out of AISI 310S of a thickness of 6 and 4 mm, fitted with a loading door. There is also a gas burner with a safety device.
