Abstract

The invention relates to a steam supplying device in the field of metallurgy, in particular to a steam supplying device of an RH vacuum refining furnace, which comprises a heat accumulator connected with a steam header of an evaporation cooling system of a converter, and a fuel gas type steam overheating device connected with the RH vacuum refining furnace; the steam inlet end of the heat accumulator is connected with the steam header of the evaporation cooling system of the converter; the steam outlet end of the heat accumulator is connected with the steam inlet end of the fuel gas type steam overheating device; and the steam outlet end of the fuel gas type steam overheating device is connected with the RH vacuum refining furnace. The steam supplying device fully utilizes steam produced by the converter; and secondary energy source is used in the steam supplying device of the RH furnace, thereby saving investment, reducing energy consumption, saving operating cost and meeting the requirement of circular economy.

Description

technical field [0001] The invention relates to a steam supply device in the field of metallurgy, in particular to a steam supply device for an RH vacuum refining furnace. Background technique [0002] All RH vacuum refining furnaces need to be connected with a steam supply device, because the RH vacuum refining furnace needs superheated steam at a certain temperature and pressure to vacuumize to meet its vacuum refining requirements. The steam supply device of the existing RH vacuum refining furnace is a fast boiler steam supply device, which uses a fast boiler to supply steam, so a set of fast boiler is needed, which is not conducive to saving investment, but also increases energy consumption and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a steam supply device for the RH vacuum refining furnace that makes full use of the secondary energy source (steam generated by the converter), which not only saves...
