Measurement of unevenness in the lining of an induction crucible oven for melting metals, using a feeler arm with a rotating sensor wheel at its tip that can be used at high temperatures with a heat resistant scanning mechanism

摘要

Measurement device for measuring unevenness on the lining of induction crucible ovens for melting metal at high temperatures. The device has a gear housing (2), a lifting rod (3) to which is fastened a support arm (19) with a moving feeler arm (6). The feeler has a rotating sensor wheel at its end. The lifting rod can be displaced vertically and at the same time is mounted in a revolving stage so that it can be rotated relative to the gear housing.
