A nozzle which can be used repeatedly for the supply of liquid metal is made up of individual, hollow, refractory sections fitted together side by side in a metal frame. The hollow elements of the nozzle may feature, in addition to at least one longitudinal channel for the supply of liquid metal, channels to accommodate heating elements also running in the longitudinal direction.

Nozzle for strip casting

The invention relates to a device for introduction of gases into reaction vessels containing liquids, especially vessels undergoing thermal stress, in particular filter housings for metal melts, using a gas-permeable body of heat-resistant material, fitting into a metal sleeve anchored in the wall of the reaction vessel. The wall of the reaction vessel consists of three different layers, namely a rigid inner layer of heat-resistant material, a loose intermediate layer of bulk material, and a casing of metal. The metal sleeve extends from the outside into the loose intermediate layer, the rigid inner layer and the gas-permeable inlet body are directly adjacent to one another, and the boundary surface of the gas-permeable inlet body has a permanently applied, thoroughly gas-tight cover of ceramic material.
