APPARATUS FOR BRAKING ROLLED PIECE Russian patent published in 2004 - IPC

FIELD: metallurgy, namely equipment of merchant bar rolling mills. SUBSTANCE: apparatus for braking rolled piece includes raising777 valves arranged between rollers of receiving roller table of cooler; mounted in parallel relative to said valves stationary straightening grooves divided by means of lengthwise slit along bottom of first grooved pass by two members and builtup two-pole braking electromagnets whose different sign poles are rigidly coupled by their upper parts with members of straightening groove and by their lower parts coupled with core that carries exciting winding. Core with exciting winding is movably mounted in vertical guides, it is spring-loaded from upwards and provided with motion drive unit, for example with two- position pneumatic cylinder. It is not necessary to demount the whole apparatus when mode of rolling mill is changed from mode for making cooled rolled stock to mode for making hot rolled pieces. EFFECT: prevention of negative influence of high temperature upon exciting winding of braking electromagnets during hot rolling process, elimination of using special winding wires and insulation materials resistant against high temperature. 1 dwg
