Аннотация

Route maps for the production cycle of operation and repair of continuous casting machine slab rolls in the Azovstal’ and Il’ich Metallurgical Combines (Mariupol’) are presented. It is shown that the complete roll operating cycle in horizontal, curvilinear, and radial sections of the secondary cooling zone as their diameter changes as a result of wear, grinding, and surfacing, makes it possible to increase roll running time, to reduce purchasing expenditure, technical servicing, and restoration. It is established that an increase in secondary cooling zone roll life with diameter 380–270 mm with unchanged composition of the basic and surfacing metal is provided by surfacing technology with formation of a corrosion-resistant surface layer of individually deposited welds with a gap between adjacent welds.
