FIELD: process engineering.
SUBSTANCE: set of inventions relates to power recovery in production of steel or nonferrous metal billets and units to this end. Proposed method consists in trapping heat power and biller residual hear by heat exchangers. Note here that heat is derived into heat transfer medium for its heating. Then, heat is derived via heat carrier pipelines to electric power generator and/or other heat consuming equipment in whatever process. Note here that heat carrier is transferred in said pipelines by pump. Note also that said heat carrier represents mineral or synthetic oil or salt melt not generating steam pressure above 2 bar.
EFFECT: higher efficiency of heat recovery, simplified process and unit.
