METHOD OF FEEDING BILLETS TO TUBE COLD ROLLING MILL STAND WITH LATERAL FEED Russian patent published in 2013 - IPC B21B21/04 

FIELD: process engineering.

SUBSTANCE: proposed method comprises feeding the billets onto intake table and displacing them for leveling their ends, shifting mandrel rod and billet jaw along rolling axis through billet length, transfer of billet from intake table to rolling axis, moving mandrel rod back into working position, feeding it into billet and locking it, and feeding the billet into strain source by billet jaw. Better lubrication and heat withdrawal are ensured by feeding lubricant to rolling axis via rod fitted into the billet and locked by lever arranged at rod mount and having one end provided lubing head and opposite end engaged with lubing head drive hydraulic cylinder. Note here that lubrication is fed continuously during rolling.

EFFECT: higher quality of tubes and process efficiency, longer life.
