Novoural'sk (Sverdlovsk region)
the mechanical repair shop of the branch "Manufacture of non-ferrous metals" JSC "Uralelectromed" (metallurgical complex of UMMC) has completed fabrication of the caisson for cooling a shaft furnace "Production of polymetals" (city of Kirovograd). Characteristics of the unit are impressive: the length is 8 meters, the structure includes 23 multiple positions, for a total of 106 items. Parts joined to each other by welding. The total length of the welds will be 700 m.
Manufacture of the caisson was held in four stages under the careful supervision of experts of the technical control Department. On the first execution of the blanks from rolled steel. In the second stage, all preparations have been Stripping and processing machines. Next, mechanics on the Assembly of metal joined parts together and finally checked out the geometric parameters: size, shape, correctness of recruitment. The fourth stage is sealed – is nearing completion.
- Design data sizes we produce for the first time and come to the process responsibly. The caisson is more demanding, since it will be operated under pressure in extreme conditions at the operating temperature of 200 degrees. The slightest flaws of the weld can lead to rupture of the vessel, - said the Deputy head of the Department Evgeny Bessonov.
After brewing all seams will be carried out hydro testing using the high-pressure pump for leaks. The finished product is planned to send to the customer at the end of June.
reference:
the integral heat sink element intended for the cooling of the walls and vault of the melting furnace. The device is a sealed container, inside which circulates the coolant under pressure. Increased pressure necessary to raise the boiling point of the liquid and to prevent its transformation into vapor.
