The new 3-roll reducing & sizing block 435 implemented in the bar mill at SMK, Japan

摘要

Markets have been demanding even larger diameter specialty bar quality (SBQ) products with close tolerances. Thus another type of 3-roll reducing & sizing blocks (RSB) has been developed that is even stronger than the 370++ heavy duty RSB for bar sizes up to dia. 100 mm. The 435++ and the equivalent C-modules are designed to finish bar sizes up to dia. 130 mm with SBQ accuracy.
