Abstract

Sposób wytwarzania bebnów lancuchowych przenosników zgrzeblowych, zwlaszcza górniczych, polega na tym, ze wykonuje sie odlewy bebnów z zeliwa sferoidalnego, które nastepnie poddaje sie procesowi austenityzacji w temperaturze co najmniej 850°C oraz hartowaniu izotermicznym w kapieli o temperaturze 250-450°C, z wytrzymaniem w tej temperaturze poprzez co najmniej 20 minut, a nastepnie schladza sie do temperatury otoczenia, korzystnie poprzez chlodzenie swobodne. Po obróbce cieplnej wykonuje sie obróbke wykanczajaca powierzchnie robocze zebów i gniazd przez co najmniej jedno narzedzie (3), dzialajace na zasadzie elektroerozji.The method of manufacturing drums of chain card conveyors, especially mining ones, consists in casting drums from ductile iron, which is then subjected to the austenitization process at a temperature of at least 850 ° C and isothermal quenching in a bath at 250-450 ° C, with withstand at this temperature for at least 20 minutes and then cool to ambient temperature, preferably by free cooling. After heat treatment, finishing work is carried out on the working surfaces of the teeth and sockets by at least one tool (3), working on the basis of electroerosion.
