Abstract

Sposób hartowania powierzchniowego wielkogabarytowych kół jezdnych i zębatych do zastosowań przemysłowych w zakresie utwardzenia, charakteryzujący się tym, że prowadzi się grzanie indukcyjne powierzchni tocznych dla stali do ulepszania cieplnego elektrodami pionowymi o długości obejmującej co najmniej szerokość hartowanego koła jezdnego rozmieszczonych w co najmniej w czterech punktach na obwodzie hartowanego koła, które obraca się, przy czym odległość elektrody od powierzchni hartowanej powierzchni wynosi od 2 do 10 mm, następnie po osiągnięciu ustalonej temperatury schładza zanurzeniowo, jednocześnie do uzyskania temperatury od 250°C do 500°C i poddaje procesowi stabilizacji, odprężenia struktury przez okres 30 minut, przy obracającym zahartowanym wielogabarytowym kole jezdnym lub zębatym, po czym przemieszcza na miejsce odkładcze.A method of surface hardening of large-size running and toothed wheels for industrial applications in the field of hardening, characterized in that the rolling surfaces of steel for thermal improvement are inductively heated with vertical electrodes with a length covering at least the width of the hardened running wheel arranged at least in four points on the circumference of the hardened wheel, which rotates, the distance of the electrode from the surface of the hardened surface being from 2 to 10 mm, then after reaching the set temperature, it is immersion cooled, simultaneously to a temperature of from 250°C to 500°C and subjected to a stabilization process, relaxation of the structure for a period of 30 minutes, with the hardened large-size running or toothed wheel rotating, and then moved to a storage place.
