Author intended to improve the properties of ordinary cast iron rolls (chilled rolles and sand rolls) in steel works in applying heat treatment processes (annealing or quenching), and studying concretely with many rolls, the author has induced it into practical operation with excellent success at the Imperial Steel Works, Yawata. The results of experiments are as follows ; (1) For the annealed cast iron rolls, heating for more than 6 hrs. at 700℃ is quite effective to remove casting stresses and also to improve the properties of rolls themselves without any fear of reducing their surface hardness. (2) The quenching method for cast iron sand rolls has been succeeded to increase their surface hardness very easily and to get a splendid result in practice with no sign to cause any damage. Thus the author has gratefully been able to propose a new important improvement in this field.
