Several  technologies are developed for the above casters.  In the technology developed by Mannesman demag Huettentechnik  thin slab of 40mm to 70mm thickness and 1200 mm width can be produced. The features are;

• A narrow submerged nozzle
• Vertically curved mould with parallel broad faces that guide the strand vertically
• Adjustable mould width
• Dry casting technique

In addition there are twin roll caster, drum and ring caster, sinfle roll caster, rheocaster and powder rolling caster. Details can be seen in the references given at the end of the lecture.

Mist Spray Cooling

In mist spray , cooling is provided by a mist which is a two phase mixture of air and water; water droplets are finely distributed in the air jet.  Air in which fine water droplets are distributed is blown on to the casting section; the water disperses on the casting section surface in the form of a mist. The mist spray provides uniform cooling. For the mist, control of volume flow rate of air to volume flow rate of water and upstream pressure must be suitably selected. The condition of the mist stream is strongly affected by the design of the nozzle
