FIELD: metallurgy. ^ SUBSTANCE: two-high operating stand helical-rolling stand rolling contains stand, drums with installed in its bottom part rotary block, located in drums working roll, swiveling device of drums for feed angle. Swiveling device of drums for feed angle are implemented in the form of coaxial located thrust screw and hydraulic tappet, which are installed in cover of rolling mill stand. Each drum is outfitted by additional hydraulic tappet, located in rolling mill stand and cooperating with installed in bottom part of drum rotary block, and additional rotary block, mounted in the top part of drum. Each tilting gear of drum for feed angle cooperating with additional rotary block. ^ EFFECT: reliability growth and durability increasing of structure of two-high operating stand helical-rolling stand rolling, expansion of its technological abilities and maintenance improving. ^ 2 dwg |
