AI Technical Summary

Technical Problem

The high cost of manufacturing high-power immersion heaters for non-ferrous metals is a result of the expensive electrically insulating ceramic powder used in their construction, making it economically challenging to increase heating capacity without significantly increasing costs.

Method used

The immersion heater design incorporates a partitioned sheath with a first compartment filled with electrically insulating ceramic powder and a second compartment filled with inert material or gas, reducing the need for expensive ceramic powder and minimizing thermal drafts through the use of refractory ceramic insulators and gases like argon.

Benefits of technology

This design allows for increased heating capacity while reducing manufacturing costs and preventing thermal drafts, thus enhancing the efficiency and cost-effectiveness of the immersion heater.

Abstract

An immersion heater (100) configured to come into contact with an object to be heated (90), particularly a molten nonferrous metal, comprising: a sheath (120) configured to come into contact with the object to be heated, partitioning a first compartment (150) filled at least partially with electrically insulating ceramic powder (130); a partition wall (140) located within the first compartment (150) and partitioning at least a second compartment (145) filled at least partially with an inert material; and a plurality of heating elements (115, 116) located between the sheath (120) and the wall (140) within the electrically insulating ceramic powder (130).
