Mechanical Components

Industrial ceramics have significant applications in the manufacturing of mechanical components such as bearings, seals, cutting tools, and nozzles. Ceramic bearings and seals, due to their high hardness, low friction coefficient, and wear resistance, are commonly used in high-speed rotating and high-precision equipment like machine tools, turbines, and pumps. Ceramic cutting tools maintain extremely sharp edges, making them suitable for machining hard alloys and ultra-hard materials. Ceramic nozzles are used in high-pressure water jets and spraying equipment, providing precise spray control and durable service life.

Semiconductor Manufacturing

In the semiconductor manufacturing industry, silicon carbide is used for producing wafer substrates, furnace tubes, heating elements, and thermocouple protection tubes due to its stability at high temperatures and high thermal conductivity. These silicon carbide components can withstand extreme temperature changes while maintaining structural integrity and providing precise thermal control, which is crucial for the high-precision manufacturing of semiconductor devices. As the use of silicon carbide in power electronics increases, its importance in the semiconductor industry continues to grow.

Power and Energy

In the power and energy sectors, mechanical seals are primarily used in circulation pumps and boiler feedwater pumps. These devices typically operate under high temperatures and pressures, requiring extremely stringent sealing. Mechanical seals prevent fluid leakage under such extreme conditions, ensuring system safety and reliability.

Drilling Bits and Mining Equipment

Tungsten carbide is extensively used in drilling bits and mining equipment, particularly in oil and gas drilling, ore extraction, and tunnel boring. Tungsten carbide drill bits, known for their wear resistance and impact toughness, can efficiently drill through hard rocks and ores, reducing downtime caused by wear. Additionally, tungsten carbide is used to manufacture wear-resistant components in mining equipment, such as crusher teeth and bucket teeth, significantly enhancing the durability and operational efficiency of the equipment.

Oil and Gas

Mechanical seals are extensively used in the oil and gas industry, particularly in well pumps, gas compressors, and transmission systems. These devices often operate under high pressure, high temperature, and even corrosive conditions. The mechanical seal's role is to prevent media (such as crude oil, natural gas, etc.) from leaking out of the equipment, avoiding environmental contamination and energy waste. Moreover, mechanical seals help maintain the safe operation of equipment, preventing accidents such as explosions or fires caused by leaks.

Aerospace

In the aerospace industry, silicon carbide is used to produce high-temperature resistant, lightweight, and high-strength composite materials for aircraft engine components, turbine blades, and spacecraft structural parts. Silicon carbide composites can withstand extreme temperatures and mechanical stresses, while also offering excellent oxidation resistance and corrosion resistance, thereby improving the performance and longevity of aerospace equipment. Additionally, silicon carbide's superior thermal conductivity and low coefficient of thermal expansion ensure excellent dimensional stability in extreme environments.

Our core technology for customizing NdFeB magnets

Neodymium magnets are made from a combination of neodymium, iron, boron, and other components. These magnets are known for their high magnetism and are widely used in various industries. The core technologies involved in producing customized neodymium iron boron magnets include:

1.melt:The first step in producing NdFeB magnets is to melt and alloy the raw materials. Neodymium, iron, and boron are combined in precise proportions and melted in a vacuum induction furnace. This process ensures the uniformity of the alloy and eliminates impurities.

2.Hydrogen explosion and jet grinding:Once castings are formed, they will be crushed into particles of several micrometers. The size of the powder is crucial for determining the magnetic properties of the final magnet.

3.Pressing and sintering:Press the particles into a compact shape using a hydraulic press. Carefully control the pressing process to obtain the required magnetic properties. Then, in a carefully controlled atmosphere, sinter and compact the powder at high temperatures to combine the particles and form a solid magnet.

4.inspect:Detection technology is crucial for NdFeB magnets, ensuring their quality, performance, and safety, thus supporting our core technology.

5.Processing and molding:After sintering, the magnet undergoes further processing and forming to achieve the final desired shape and size. This may involve cutting, grinding, drilling, and surface treatment to enhance the performance of the magnet and protect it from corrosion.

6.Optional GBD process:GBD is currently one of the important development directions of Ketian, with multiple process routes. This type of magnet is widely used in fields such as the main drive motor of new energy vehicles, air conditioning compressors, and intelligent robots. It is customizable and can meet the needs of customers.

7.magnetization:The final step in manufacturing customized NdFeB magnets is magnetization. Strengthen the magnetic field to align the magnetic domains inside the magnet, thereby maximizing its magnetic strength and performance.

In addition to these core technologies, there are several other important considerations in the production of customized neodymium iron boron magnets, such as quality control, surface treatment, and magnet assembly.
