| Abstract: | The structure and hardness of gray iron local chilled were studied. The technological parameters of chill have been established.The results show that as-cast hardness of slideway was promoted.The hardness homogenization of slideway and the section homogenization of lathe bed were improved by using chill over the slideway of lathe bed. |
