Vertical Tower Mills (VTM/Vertimill)

ONA produces high chrome casting liners mainly include tower mill liners, blow bars, hammer plate, hammer head, impact plate, distributor plate, feed tube, cavity wear plate and etc. High Chrome parts are available from 15% to 26% High alloys. With chromium steel, the carbon is chemically bonded in the form of chromium carbide. The wear resistance of chrome steel is based on these hard carbides of the hard matrix, whereby the movement is hindered by offsets, which provides for a high degree of strength but at the same time less toughness.

In common, it will go through with chemistry test, hardness test, magnetic particle examination test and dimension test.
