calcified coke

Is by the degree of hardness low porosity high high quality refinery coke the pellet which is made after the high temperature roasting, available each kind of friction material. In the friction material joins the calcined coke and the graphite which becomes according to certain proportion mix can enable the friction material to have the perfect overall performance, is advantageous in preventing the pick-up of metal, enhances the friction performance. Moreover, the coke porosity was high, enhanced the friction material friction coefficient, reduced applied the brake the noise, reduced when the high temperature rubbed the material the hot decline.
