Steam heat accumulator for converter vacuum melting

The utility model relates to a steam heat accumulator for converter vacuum melting, which solves the problem that the unreasonable structure at present results in weak heating rate, heating efficiency and heating uniformity, large difference in temperature of the middle and the two ends of the accumulator, and the like. Therefore, the steam heat accumulator for converter vacuum melting mainly comprises a shell 1, a water inlet pipe 2, a water outlet pipe 3 and a steam pipe 4. At least one steam branch 5 is connected on the steam pipe. A jetting or ejecting type heater 6 is connected with the steam branch 5. The utility model has the advantages of uniform heating, high heating efficiency and full heat exchange, which can meet the requirement of recycling the afterheat steam.
