Abstract

The wheel is heated to the hardening temp. rotated in a vertical plane and cooled by jets of hardening zone. Pref. the fluid is supplied to the rim under a pressure of 2 to 5 atm. for 120 to 200 sec. and to the disc and zones of transition to the hub under pressure of 1 to 3 atm. for 50 to 120 sec.
