FIELD: foundry. SUBSTANCE: process includes feed of metal into space limited by cylindrical surfaces of two rolls rotating in opposite directions and two side walls of floor. Pressure is applied to walls to press them against faces of rolls. Continuous evaluation of state of mechanical contact of walls of floor to faces of rolls is conducted in process of casting by change of entraining efforts acting on each wall of floor at level of each roll in direction of removal of finished product. Representative value characterizing friction factor at level of each surface of mechanical contact of walls of floor and faces of rolls is found on basis of measured forces of pressure or pressing and of entraining efforts. After this magnitudes of mentioned value is compared with specified value determined in advance and results of this comparison are used to adjust one of parameters of casting process to bring this value to mentioned specified value. For example, forces of pressure or pressing of walls of floor or their positions with reference to faces of rolls are adjusted. Gear for implementation of process is equipped with means measuring entraining efforts acting on walls of floor from side of rolls in process of their rotation which include two transmitters per each wall of floor measuring efforts emerging as result of friction and acting on walls of floor from side of each roll. Transmitters measuring efforts are placed correspondingly on both sides from center plane of removal of finished product. Gear also has two supporting means to hold walls of floor in direction of removal of finished product located on side walls. Transmitters measuring entraining efforts are put into supporting means. Gear is fitted with transmitters measuring positions of walls of floor with respect to faces of rolls and with vibration transmitters per each wall of floor. EFFECT: improved control over mutual contacts between side walls of floor and rotating rolls and avoidance of abrasive wear-out of walls of floor. 8 cl, 2 dwg
