B – vacuum; The coolant furnace is designed for annealing; 2.5 – the volume of the working space in dm3; 25 – the maximum operating temperature divided by 100, i.e., 2500 ° C
B – vacuum, Su – for drying, 30 – the volume of the working space in dm3, 6 – the maximum operating temperature divided by 100, i.e., 600 ° C, A – the furnace is equipped with an adsorber
a massive copper mold was used in the furnace, as well as a printed crucible made of stabilized (calcium oxide) zirconium dioxide. The furnace has been working for several years at one of the non-ferrous metallurgy enterprises in the production of platinum ingots according to GOST
The time of movement of the special product, from the moment of depressurization of the furnace to immersion in the quenching medium is less than 20 seconds;
