silicon carbide ceramic drum barrel for grinding
Silicon carbide Grinding barrels, also known as silicon carbide grinding drum manufacturing methods, including the following steps：
(1) ingredients, the silicon carbide added to the reaction catalyst and additives, while stirring with water, stir evenly into a slurry or powder material;
(2) the formation of raw materials, the slurry or powder materials using mold through grouting or isostatic pressing to produce the appropriate size of the silicon carbide grinding barrels of the blank;
(3) drying, repair and sintering of the billet: the billet is dried and the dried billet is repaired. After the repair, the green body is filled in a vacuum furnace and sintered by adding silicon alloy.
(4) Finished product after sintering: The sintered silicon carbide grinding drum is installed on the CNC machining center for finishing
