Cemented carbide round rods, namely tungsten carbide rod, are products prepared from tungsten carbide powder and other bonding metals by powder metallurgy production process. Mainly used to make drill bits, wear-resistant parts, etc.
Powder metallurgy process is adopted: powder making → powder mixing → wet grinding → mixing → pulverizing → drying → sieving → adding molding agent → drying → sieving to obtain a mixture → granulation → pressing → molding → low pressure sintering → molding ( Blank) → cylindrical grinding and fine grinding (blank is not used) →detecting size → packaging → warehousing
Solid round rod is a tungsten carbide rod without a hole in the center.
Single straight hole round rod is a tungsten carbide rod with a straight cooling hole.
Double straight hole round rod is a tungsten carbide rod with two straight cooling holes.
The round rod with three straight holes is a tungsten carbide rod with three straight cooling holes.
The single-hole spiral round bar is a tungsten carbide bar with a spiral cooling hole.
The double-hole helical round rod is a tungsten carbide rod with two helical cooling holes.
