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
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
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
