Metallurgical vessel cooling and safety system

摘要

A metallurgical vessel cooling system with cooling chambers provided on the wall of the vessel is arranged so that the cooling chambers can be quickly emptied of the cooling water by connecting the chambers to a pressure gas line. This system is particularly useful for one or more converters with a converter hood having cooling chambers extending in the generatrix direction and connected to horizontally extending coolant passages. These passages are in turn connected to a coolant supply system by means of coolant supply and drain lines. The supply or drain line contains supervisor or signalling devices for checking the pressure and/or temperature and/or amount of coolant. These signalling devices, in the case of a deviation from a predetermined value, actuate controls for separating the supply and drain means from the coolant supply system and connecting one of these conduit means to the pressure gas line.
