FIELD: method for registering angular position of rolls according to marks applied onto their end surfaces in plants with pilger mills mounted in shops for hot rolling. ^ SUBSTANCE: method for detecting mark of rotating roll of rolling mill applied onto end surface of roll comprises steps of arranging pickup for receiving signal; measuring signal at passing mark across pickup; using as mark jointly mounted flag; measuring electric resistance of laminar water stream supplied from roll cooling circuit between tip spaced by some distance from flag plane and electrically insulated from cooling circuit and grounded structure of rolling mill; registering time moment of mark passing through line of water stream according to lowered resistance due to stream length shortening in the result of its cutting off by flag. At next turning of roll by 180° flag falls by gravity and prevents water stream cutting off. ^ EFFECT: simplified reliable method for registering angular position of roll of hot rolling mill according to marks applied on roll end. ^ 2 cl, 2 dwg
