Abstract
1. Device for measuring the temperature in a converter with a radiation measuring instrument (17), which is connected to one end of a rectilinear channel (14) to receive the radiation propagated through the channel, whereas the other end of the channel opens out into the liquid molten steel and an inert gas or a low reaction gas or gas mixture at excess pressure flows into the molten steel at this end, characterised in that the channel (14) has a cross sectional area that is not greater than 1 cm**2 at least at the end terminating at the molten steel and the discharge velocity of the gas or gas mixture is large enough to produce a flow of at least 10 gram per minute with repect to a cross section of 1 mm**2 and that a temperature radiation measuring instrument (17) is connected to the channel as radiation measuring instrument.
