UPDATING OF PROCESSING METHODS OF ZINC-CONTAINING DUST AND SLUDGE FROM BLAST FURNACE AND STEELMAKING PRODUCTION

The mechanical equipment of such technological lines as the continuous casting machine of blanks ( TL MNLZ ) experiences intense both thermal and energy - force effects during casting of liquid metal into blanks , as a result of which it very quickly loses its operability . This leads to premature failure of some parts and components of the equipment and , in addition to frequent scheduled stops , also to emergency stops of the entire production line . The continuous casting machine implements a continuous casting process of liquid metal , in which prolonged , unforeseen downtime is simply unacceptable . Hence , it is very important to know not only the operational reliability indicators of the MNLZ equipment , but also how well the equipment is adapted for its restoration operations . The present work is aimed at assessing the maintainability of technological units of the continuous line of the MNLZ in terms of the time parameters of its restoration .
