Rolling of tungsten base cermet in four-roll grooves

The sintered cermet pieces 30 mm in diameter were used to roll square bars sized 32, 16 and 12 mm (the one-pass reduction ratio in the range 1.25-1.80). Studies were made of the contact stresses and energy parameters in the rolling of tungsten bars. The results obtained can be useful in the the design of new equipment and development of industrial technology
