METHOD FOR COILING THIN BELT AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2005 - IPC

FIELD: metallurgy, possibly manufacture of thin metallic belts with amorphous structure by continuous casting of melt metal onto quickly rotating cooling casting drum, namely methods and apparatuses for coiling such belts.

SUBSTANCE: method of coiling thin belt with use of coiling drum and guide systems comprises steps of feeding leading end of belt into coiling drum and trapping it on wall of said drum by means of trapping unit; turning belt approximately by 90° around its lengthwise axis in front of inlet of coiling drum with use of guide system; then uncoiling leading end of belt and releasing it in central part of coiling drum in such a way that edges of belt are parallel relative to bottom of drum and plane of belt is almost parallel to wall of said drum; gripping leading end of belt on inner surface of wall of coiling drum by means of gripping unit and going on coiling process in direction from wall of coiling drum to its center till forming desired diameter coil. Apparatus for performing the method includes guide system that may receive belt from casting drum, turn it by 90° as usually belt is formed on casting drum with generatrix parallel to horizontal line and wall of casting drum is normal relative to it and introducing belt into coiling drum in such a way that edges of belt are parallel to bottom of coiling drum and its surface is approximately parallel to wall of coiling drum. Invention allows sustain revolution number of coiling drum in range ±5% of predetermined revolution number.

EFFECT: possibility for producing coiled thin belt at keeping technological properties of amorphous structure of its material.
