clamping device for end plate of steel converter

摘要

A device for clamping the base plate of a steel refining converter against a plate support ring attached to the casing of the converter comprises a plurality of rotatable brackets arranged to be beneath and around the circumference of the plate, each bracket being rotatable on a metal spindle passing through two parallel support flanges attached to the ring, and having a first shoulder with a very hard surface to be pressed against the base plate when the base plate is clamped in position, and an internally threaded second shoulder into which is screwed a retaining screw at the end of which is a ball which, when the base plate is clamped in position, engages in a semi-cylindrical groove in a metal bolt which engages in openings formed in each of said support flanges.
