I. How to efficiently cut tungsten steel bars?
Tungsten steel ( Tungsten Carbide ) rods, due to their extremely high hardness and wear resistance, require professional cutting methods:
- Diamond wheel cutting (Recommended): Actively use diamond wheel equipment to achieve precise cutting through high-speed grinding. Suitable for regular diameter rods.
- Electric Discharge Machining ( EDM ) : Cuts complex shapes through the principle of electrical discharge erosion. Continuous supply of coolant is needed to prevent overheating.
- Laser cutting : Uses a high-energy laser beam to melt the material. Suitable for fine processing of superhard alloys, but the equipment cost is high.
II. What is a tungsten steel boron control rod?
A tungsten steel boron control rod is a control rod used in nuclear reactors, mainly made of tungsten steel and boron. The following are the material characteristics of tungsten steel boron control rods:
Tungsten steel : It has high strength, high hardness, high temperature resistance, and good wear resistance. It can withstand the high temperature and high pressure environment inside a nuclear reactor, ensuring the structural stability and mechanical performance of the control rod, making it less prone to deformation or damage during long-term use.
Boron : Boron has a strong neutron absorption capacity. In a nuclear reactor, boron can effectively absorb neutrons, thereby controlling the rate of nuclear fission reactions.
III. How does a boron carbide control rod work?
Working principle : The nuclear fission reaction in a nuclear reactor is initiated by neutrons. The boron in the control rod can absorb a large number of neutrons. When the control rod is inserted into the reactor core, it will absorb more neutrons, reducing the number of neutrons.
This reduces the rate of the nuclear fission reaction, and can even stop the reaction; when the control rod is withdrawn from the core, the number of neutrons increases, and the nuclear fission reaction rate accelerates.
This regulates the power of the reactor, keeping it in a safe and stable operating state.
Application scenarios : Mainly used in various types of nuclear reactors, such as pressurized water reactors and boiling water reactors, it is an important component for ensuring the safe and stable operation of nuclear reactors.
Tungsten steel boron control rods play a key role in the startup, shutdown, power adjustment, and response to various abnormal situations and accidents in nuclear reactors.
III. What are the differences between cemented carbide round bars and tungsten steel boron control rods?
Cemented carbide round bar | Tungsten steel boron control rod | |
|---|---|---|
Core components | WC-Co (Boron-free) | Contains boron (such as B ₄ C ) tungsten-based materials |
Core function | Mechanical properties (hardness / wear resistance) | Neutron absorption and reaction control |
Application environment | Industrial machinery stress environment | High temperature, high radiation nuclear reactor environment |
Performance focus | Abrasion resistance, compressive strength | Neutron absorption efficiency, radiation resistance |
Typical industries | Manufacturing, mining | Nuclear energy industry |
Powei is a manufacturer of cemented carbide round bars.
IV. Where can I buy silicon carbide tubes and rods, etc.?
Lizhou Cemented Carbide mainly deals in tungsten-based cemented carbides (such as tungsten carbide rods) and does not produce silicon carbide tubes and rods. For purchasing silicon carbide tubes and rods, it is recommended to contact professional ceramic material suppliers, such as:
- Online platforms : Alibaba industrial products, Made-in-China.com;
- Direct purchase from manufacturers : Shandong Jinhong, Henan Xinfrui, and other silicon carbide companies;
- Industrial markets : Customized from ceramic and photovoltaic equipment suppliers.
