Abstract
Apparatus for manufacturing steel includes a hood adapted to be connected to the mouth of a converter. The hood has at least one conduit opening into it for introducing secondary materials into the hood. In order to arrange monitoring points of the pressure within the hood cheaply and conveniently, the pressure-measuring points are incorporated into the upper sides of the conduits. Each conduit may also have a connection which enables it to be flushed out with an inert gas, thus preventing a dangerous build up of inflammable gases within the conduit.
