Твердосплавные пластины are essential components in a variety of industries, including manufacturing, mining, and metalworking. Known for their exceptional hardness, wear resistance, and durability, carbide plates are the go-to solution for applications requiring strength and longevity. But what makes them so special? Let’s break down everything you need to know about carbide plates, from their composition to their applications and even how to select the right one for your needs.
Что такое твердосплавная пластина?
Carbide plates, also known as tungsten carbide plates, are made from a composite material primarily consisting of tungsten carbide (WC) and a metallic binder, typically cobalt or nickel. These plates boast incredible properties, including extreme hardness and high wear resistance, making them ideal for heavy-duty applications.
Think of a carbide plate as a shield that stands up to the harshest conditions—whether it’s high heat, intense friction, or corrosive environments.

Технологический процесс производства Твердосплавные пластины
Ever wondered how carbide plates are made? Here’s the simplified production process:
- Приготовление порошка:
Tungsten carbide powder is mixed with binders (like cobalt) to create a uniform mixture. - Прессование:
The mixture is pressed into the desired shape under high pressure. - Спекание:
The pressed plate is heated at extremely high temperatures in a sintering furnace. This fuses the particles and increases the material’s density. - Отделка:
The plate is ground and polished to meet precise specifications. - Контроль качества:
Every plate undergoes rigorous testing to ensure it meets hardness, toughness, and wear-resistance standards.
