The horizontal high-vacuum resistance furnace with multi-way gas shut-off model FASTJET type TPHF 80/80/120HP represents the most advanced for heat treatment of quenching and related tempering, annealing, solubilization, aging, stress relieving, etc., adapting, for the specificity of the gas path, to the most varied geometries of the charge and the parts.
Size (WxHxL): 5x4x7 m
Hot zone (WxHxL): 800x800x1200 mm
Max temperature: 1320 °C
Charge: 1000 kg
Final vacuum: 1E-5/1E-6 mbar
Operating vacuum: 1E-4/1E-5 mbar
Max cooling pressure: 10 bar
During heating, the furnace allows to heat dense or monolithic charges by forced convection by circulating gas at a pressure of 1 to 1.5 bar absolute, up to a temperature of 800 °C and continuing vacuum heating by radiation.
The furnace, having a power distribution over 3 independent zones, adapts the heat flux by radiation toward the charge to the actual distribution of the masses and surfaces of the charge itself, allowing an exceptional thermal uniformity and a minimum power absorption, avoiding the risk of local overheating of the parts.
The furnace gives the possibility during the shut-down phase to arrange the circulation of gas (nitrogen , argon, etc.) at a maximum pressure of 10 bar absolute cooling the charge from below, from above or from both sides, allowing the faster drop in temperature of the charge with the best uniformity.
