Energy resources were saved at the Polymetals Plant when the converter was heated up
Kirovgrad (Sverdlovsk Region)
The Polymetal Production Branch of Uralelectromed JSC (an enterprise of the UMMC metallurgical complex) has developed a special cover for the converter, which made it possible to eliminate heat losses and save energy resources. the repair had to be warmed up for two days. To put the unit into operation and to "warm up" it required a significant consumption of gas and air. The developed cover improved the production process, reducing energy consumption, - said Vladislav Borisov, head of the converter department of the branch. The cover is a multi-layer structure and consists of heat-resistant metal and heat-insulating material. It is installed on the neck of the converter and helps to keep heat inside the unit. Previously, three or four burners were required to warm up one converter, but using the lid, two are enough. The metallurgists of the branch intend to use the new device not only during the preparation of the converter for working with melts after repair. In the future, the cover will also be used during prolonged downtime in anticipation of melts, for example, during the annual overhaul of a shaft furnace. This will make it possible to keep the converter in a hot standby using less natural gas and air. The lids for the remaining converters will be manufactured by the employees of the Non-Ferrous Metals Production Branch (Verkh-Neyvinsky settlement, Sverdlovsk Region).
