APPARATUS FOR COOLING WHEEL RIM IN THE PROCESS OF THERMAL STRENGTHENING OF RAIL CAR WHEELS Russian patent published in 1997 - IPC

Abstract RU 2082775 C1

FIELD: car building. SUBSTANCE: apparatus has supporting rollers and cooling liquid supplying sprayers. Sprayer positioned between rollers is made composite and combined, i.e. of double-plane action. Both parts of this sprayer have horizontal strip oriented in direction opposed to that of vertical strip. Vertical strips of combined sprayers are positioned at an angle of 75-85 deg relative to horizontal strips. Two sprayers positioned at other side of supporting rollers are made of single-plane action. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 3 dwg, 1 tbl
