Are you in a corner of the hot northern hemisphere? Or is it somewhere in the southern hemisphere with ice and snow? No matter how! Between the twists and turns, there will always be another rotation! Then, it should always meet with the anti-skid nails on automobile tires. After all, the anti-skid nails always appear in cold and humid areas. Cemented carbide anti-skid nails are mainly embedded in automobile tires to prevent automobiles from skidding on wet skating surfaces. They have a very wide market in many European countries.
The Anti-skid nails for automotive tires on ice and snow pavement include a flange at the head, middle wing and lower end of the core on the cylindrical nail body, and the flange and the flange form an acute angle with the nail body. When the anti-skid nail is used, it is not only easy to install, but also has anti-falling effect. According to different uses and grooves, their specifications have different requirements, but their material requirements are: wear resistance, low temperature resistance, high hardness and so on.
Compared with other anti-skid nails, cemented carbide anti-skid nails have many advantages, such as high hardness and high wear resistance; low pressure on the surface, on the basis of ensuring minimum damage to prevent slippage; simple installation and disassembly, and reusable.
The holes used to insert cemented carbide anti-skid nails in automobile tires can be easily drilled out, and can be easily removed even without professional installation tools. In addition, users can also install or disassemble cemented carbide anti-skid nails according to different seasons. Without using them, they can easily take out and store them for the next reuse. When choosing carbide anti-skid nails for automobile tyres, users should first consider the thickness of automobile tyres and the depth of holes.
Generally speaking, cemented carbide anti-skid nails for automobile tyres are made by inserting the anti-skid nails into the nail sleeve of steel or other materials, and then inserting the whole package into the outer layer of the tyre. In this way, the force area of the tire can be increased and the tire can be protected to a certain extent. In the course of driving, under a certain force, the carbide anti-skid nail of the tire can be properly embedded in the ice surface, so as to enhance the grip of the tire on the icy road, greatly reduce the slippage of the car, and effectively reduce the accident rate.
So, by the way, how are carbide Anti-skid nails made for automobiles? The preparation process of automotive cemented carbide anti-skid nails can be divided into four basic stages:1. Removal of forming agent and sintering process in this stage have the following changes: removal of forming agent, decomposition or vaporization of forming agent gradually with the increase of temperature in the initial stage of sintering, and removal of sintering body. At the same time, more or less of forming agent is added to the sintering body, and the amount of carbon will change with the type, quantity of forming agent and sintering process. The oxide on the powder surface is reduced. At sintering temperature, hydrogen can reduce the oxides of cobalt and tungsten. If the forming agent is removed in vacuum and sintered, the reaction between carbon and oxygen is not strong. The contact stress between powder particles gradually disappears, the bonded metal powder begins to recover and recrystallize, the surface diffusion begins to occur, and the compaction strength increases.2. At the temperature before liquid phase appeared in the solid phase sintering stage, besides continuing the process that happened in the previous stage, the solid phase reaction and diffusion intensified, the plastic flow increased, and the sintered body appeared obvious shrinkage.3. In the phase of liquid phase sintering, when the liquid phase appears, the shrinkage of the sintered body completes quickly, and then the crystallization transformation occurs, forming the basic structure and structure of the alloy.4. At this stage of cooling, the structure and phase composition of tungsten steel vary with different cooling conditions. This characteristic can be used to heat treat tungsten steel to improve its physical and mechanical properties.At this point, you should also know why carbide anti-skid nails are used in automobile tires. They are easy to consume. They shrink when they are worn and worn every day. Although they can't be replaced every three or five times, they always think of "once and for all". It's easy to save trouble. Carbide Anti-skid nails, as their name suggests, are hard enough, wearable and just right. Of course, the most important thing is to drive safely! Life is precious~
