一、How to cut tungsten steel rods efficiently?
Tungsten steel (tungsten carbide) rods require professional cutting methods due to their extremely high hardness and wear resistance:
1. Diamond wheel cutting (recommended): Actively use diamond wheel equipment to achieve precise cutting through high-speed grinding, suitable for conventional diameter rods.
2.Electric spark wire cutting (EDM): We cut complex shapes through the principle of discharge corrosion and continuously supply passive coolant to prevent overheating.
3.In laser cutting, we use a high – energy laser beam to melt the material. This method is suitable for the fine processing of super – hard alloys, but it requires relatively high equipment costs.
Operation tips: Wear protective equipment when cutting, and use coolant to reduce thermal stress.
二. What is a tungsten steel boron control rod?
We use tungsten steel and boron as the main materials to make tungsten steel boron control rods, which are control rods applied in nuclear reactors. Here are the material properties of tungsten steel boron control rods.
Tungsten steel: It has the characteristics of high strength, high hardness, high temperature resistance and good wear resistance. It can withstand the high temperature and high pressure environment in the nuclear reactor, ensure the structural stability and mechanical properties of the control rod, and make it not easy to deform or damage in long-term use.
Boron: Boron has a strong neutron absorption ability. In a nuclear reactor, boron can effectively absorb neutrons, thereby controlling the rate of nuclear fission reactions.
三. How does the boron carbide control rod work?
Action principle: Neutrons trigger the nuclear fission reaction in the nuclear reactor. The boron in the control rod can absorb a large number of neutrons.
When the control rod is inserted into the reactor core, it absorbs more neutrons and reduces the number of neutrons.
Thereby reducing the rate of nuclear fission reaction and even stopping the reaction;
When we pull the control rod out of the core, the number of neutrons increases and the rate of the nuclear fission reaction accelerates.
In this way, the power of the reactor is adjusted to keep it in a safe and stable operating state.
Application scenario: Mainly used in various types of nuclear reactors, such as pressurized water reactors, boiling water reactors, etc., it is an important component to ensure the safe and stable operation of nuclear reactors.
Tungsten steel boron control rods play a key role in the startup, shutdown, power regulation of nuclear reactors, and in dealing with various abnormal situations and accidents.
四. What is the difference between carbide round rods and tungsten steel boron control rods?
| Comparison Items | Tungsten Carbide | Tungsten steel boron control rod |
| Core Ingredients | WC-Co（Boron-free） | Tungsten-based materials containing boron (such as B₄C) |
| Core Features | 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 | Wear resistance, compressive strength | Neutron absorption efficiency, radiation resistance |
| Typical industries | Manufacturing, mining | Nuclear power industry |
Puwei is a manufacturer of cemented carbide round rods
五. Where can I buy silicon carbide tubes and rods, etc.
Puwei Cemented Carbide mainly deals in tungsten-based cemented carbide (such as tungsten carbide rods), and does not produce silicon carbide tubes and rods. It is recommended to contact professional ceramic material suppliers to purchase silicon carbide tubes and rods, such as:
1. Online platform: Alibaba Industrial Products, Made-in-China.com;
2. Factory direct purchase: Shandong Jinhong, Henan Xinfurui and other silicon carbide companies;
3. Industrial market: customized by ceramic and photovoltaic equipment suppliers.
(Note: Silicon carbide is resistant to high temperature and corrosion, and is often used in the semiconductor and photovoltaic industries, which is different from the use of cemented carbide.)
