Abstract: Use of a mass flow cock with control units and pressure reducing systems results in an even output at changing exit dimensions respectively nozzle exit bores by an automatic balancing of the process volumes, reduces thereby the equipment expenditure and increases the maintenance intervals. This mass flow cock operates using a large pressure difference and an exact adjustment of a special cock piece at two diaphragms.

Abstract: A continuous casting slab cutting apparatus is disclosed. The apparatus permits a slab to be cut from a strand of continuous casting using a synchronized strand cutting machine. A slab roller table having a set of slab rollers is positioned such that as the strand cutting machine passes over the moving strand, the cutting burner is never positioned over any of the slab rollers. Also disclosed is a system for containing and removing smoke and other gases generated by the cutting process from the strand cutting area. The containment system includes partitions and plates as well as ventilation ducts positioned at various areas within the cutting area.
