Pressure relief apparatus for the supporting beam for metal strand casting plants, particularly curved steel strand casting plants

摘要

A pressure release device is provided for metal strand casting plants to relieve the pressure between opposed sets of supporting rolls for the strand in instances where unusual pressure build-up takes place between the opposed sets of rolls. The device is simple and inexpensive and may be positioned in the axis of the connecting rods between two opposed roll stands. The device accommodates a regular mechanical spindle-threaded nut spacing arrangement, which may be manually adjusted and avoids the problem of "freezing" which is common with such devices using a "built-in" frictional release arrangement.
