warmth insulated industrial furnace and waermedaemmender jacket therefor

摘要

The furnace has a housing (10) which consists at least partially of iron and an external heat-insulating mantle (14, 16). The latter is connected on the inside to a number of permanent magnets (18) which adhere to the furnace housing. The mantle can also be arranged subsequently on existing furnaces and, in the case of cyclic furnace operation, can be removed during cooling phases. IMAGE
