SECTION 1 -INTRODUCTION TO BRUSHES AND CARBON GRADES
Question 1:3 How Is The Carbon Brush Material Made?
The basic raw materials of retort or metallurgical coke, petroleum coke, carbon black or lamp black are combined with a variety of special additives which have been formulated in various ways.
A binder is added and this mixture is then heated under pressure and baked. In the case of electrographitic grades a further process of passing electric current through the blocks burns off the remaining carbon, this is called "graphitizing".
The total process takes approximately 7-8 weeks to complete.
