How to make ground tungsten carbide rod
Main process flow
powder milling → formula according to grade→ wet grinding → mixing → crushing → drying → sieving → adding forming agent → redrying → sieving to obtain a mixture → granulating →extrusion molding or mould pressing→ forming → low-pressure Sintering →blanks→inspect straightness, runout→ rough ground by centerless grinders → finish ground → measure the size →packing → storage
