The four basic stages of producing Tire Studs
Do you want to know how carbide non-slip tire studs are produced? Let me take you into the world of carbide non-slip tire studs, uncover the mystery.
There are four basic stages in the preparation of tire studs: removal of forming agent and pre-firing stage, solid phase sintering stage, liquid phase sintering stage, cooling stage.
The first stage: removing the forming agent and pre-burning stage. At this stage, the surface oxide of the powder is reduced, at the sintering temperature, hydrogen can reduce the oxide of cobalt and tungsten, the contact stress between the powder particles is gradually eliminated, the bonded metal powder begins to recover and recrystallize, the surface diffusion begins to occur, and the strength of the block is improved.
The second stage: solid phase sintering stage. The sintered body has obvious shrinkage.
The third stage: liquid phase sintering stage. The crystalline transformation is generated to form the basic structure and structure of the alloy.
Fourth stage: cooling stage. The structure and phase composition of tungsten steel change with different cooling conditions.
Finally, cemented carbide anti-slip nails need to pass the inspection, only qualified anti-slip nails can be stored and packaged, and finally sold out of the warehouse to open its anti-slip legendary life. The characteristics of cemented carbide non-slip nails are: long service cycle, wear-resistant and durable, removable and reusable.
