Usage of iron chromite flour in refractory industry
Iron chromite flour is ground from chromite sand by grinding machine.The available sizes are 200mesh 325mesh 400mesh 500mesh 600mesh 800mesh 1000mesh 1200mesh 1500mesh 2000mesh 2500mesh etc.
Iron chromite flour is also called iron chromite powder,iron chrome flour,iron chrome powder,chromite powder,chromite flour,chrome powder , chrome flour or cr-flour etc
Because iron chromite flour own the special heat-resistance,making it has the imcomparable advantages in refractory industry.Then it is widely used in produce refractory cement,refractory bricks,and lining and coating of some kiln which works in extrme high temperature.
