Graphite Block For Vacuum Furnace
The application of Graphite Block For Vacuum Furnace in vacuum furnaces greatly simplifies the design and manufacture of vacuum furnaces, reduces the consumption of metals such as tungsten, molybdenum, tantalum, and stainless steel, reduces the cost, improves some properties of vacuum furnace and expands the application range of vacuum furnace.
Advantages of Graphite Block
*Graphite blocks are used to make capable, reliable products.
*Graphite blocks produce electrodes that exhibit high electrical conductivity properties as well as good refractory properties (for example, high thermal shock resistance and low thermal expansion).
*Graphite blocks exhibit high mechanical strength, high thermal conductivity, and high density.
*Graphite blocks are highly machinable.
*These materials are chemically stable and lightweight.
*Resistance to Hot Metals
In aluminum smelting systems, quality blocks are used for sidewalls and linings because they have a high solubility and are resistant to the presence of hot metal. Because the blocks have limited porosity and a lengthy life cycle, metal cannot permeate them.
*Thermal Resistance
One of the main causes of block failures and problems with the lining and sidewalls of furnaces is thermal resistance, or heat. The life cycle is prolonged by exclusively employing premium carbon blocks, and the mix of fills, sealants, and manufacturing procedures for the blocks ensures continued usage even in the most demanding applications.
Application of Graphite Block
Graphite blocks are utilized in graphitization furnaces, silicon carbide furnaces, and other metallurgical furnaces. They are used as a conductive material for furnace linings in resistance furnaces. They are also used for impermeable graphite heat exchangers. Graphite blocks are most commonly used in metallurgy, electronics, steel, and chemical industries. Products made from graphite blocks are of excellent quality and they have stable performance.
Graphite blocks are utilized in metal processing as electrodes. These electrodes exhibit high electrical conductivity properties as well as good refractory properties like high thermal shock resistance and low thermal expansion. Other applications of graphite blocks include them being used in the applications of hot-pressing molds as well as being used as nozzles for continuous casting of metals. Graphite blocks are used for creating graphite plates that are used as collecting shoes for electric trains, even though their usage will decrease due to high-speed driving.
Polycrystalline graphite blocks are one of the best materials utilized in nuclear-fission applications due to their high moderating efficiency as well as low absorption cross-section for neutrons. Graphite blocks are utilized in high-temperature gas-cooled reactors. In these reactors, graphite materials are utilized as permanent reflectors on the exterior part. In the interior, they are used as replaceable reflectors. At the center, they are used as fuel-element blocks, and as a coating of small fuel particles.
How to Select Graphite Block
1、Under high speed or high pressure, it is necessary to use effective methods to dissipate the friction heat, which should be cleaned when it is used in the medium with crystal precipitation.
2. The differences of thermal expansion coefficient should be paid attention to the carbon graphite ring or bearing which are inlaid with metal parts. Assembly, the choice of excessive amount should be reasonable, not too large.
3. Before installation, two working surfaces of friction pair must be grinded. After installation, the friction pair runs firstly at low speed or starts to work in the working state repeatedly through running-in, which can be put into operation.
4. Carbon--- graphite is a kind of brittle materials. Generally speaking, its mechanical strength is lower than metals. Therefore, we should be fully aware of this during the designing of the structure and be careful in the process of machining and assembly operations, it is forbidden to beat with rigid thing to avoid cracking.
Manufacturing Methods of Graphite Block
There are many different types of processes used in the production of graphite blocks. The most commonly used methods are molding, extrusion, and isostatic pressing. The production process of graphite blocks follows many different stages. The first stage is crushing and grinding. The process begins with crushing and grinding. Next, the material is mixed and kneaded, followed by crushing and screening. The next stage includes pressing, roasting, and impregnation. In the final stages, the graphite undergoes graphitization, machining, and testing. At last, the final product is produced.
How to Use Graphite Block Safely
Sawing Synthetic Graphite Blocks Safely
The synthetic graphite blocks’ first stop beyond the storage warehouse is almost always the saw department. Here, large blocks or rounds of synthetic graphite are trimmed and partitioned based on each job's specifications. Since virtually all material used in the facility passes through one of our saws, we naturally make safety in our saw department a priority. By implementing various safety features, we enable our operators to cut material safely. Most of these safety features are built into the actual saws:
Dust Port: This feature channels dust away from the cutting platform and is connected to our dust collector. Dust ports enable dust free operations, better visibility, and good air quality.
Blade Adjustment Knob: This knob helps adjust the cutting blade's height and position. Allowing the machinist to set the blade at the proper height accommodates the safe handling of specific blocks, which come in many sizes.
Blade: There are various blade types, from diamond to carbide. Each choice of blade compound is determined for the specific material grade to be cut, and ensures that the material is cut cleanly and efficiently.
Wheel Guard: This component guards the saw's wheel inside the frame since the wheel is sharp and can easily cause accidents if left exposed.
Blade Guard: This component guards the spinning blade to prevent an accident or kickback during the job.
Blade Tensioner: The usefulness of this component is in safely ensuring that the blade isn’t too tight when working with softer material. If the blade is too tight, it can cause breakage or possibly slip off the wheels.
Passing Graphite Blocks Safely Through Lathe and Mill
From the saw department, the synthetic graphite material is generally transferred to either the lathe or mill department. Here as well, our machines have various safety features built into them.
For lathes, safety features for machining graphite blocks include the following:
Foot Brake: All lathes have a foot-enabled brake at the bottom of the machine that cuts off the spindle motor mechanically and electronically.
E-Stop Button: The Emergency Stop Button stops the motor electronically, allowing the motor to coast to a stop. This is used in situations where the foot brake is not needed to stop the lathe instantly.
Chuck Guard: All engine lathes feature a chuck guard that extends around the spindle nose. The chuck guard needs to be in the closed position to start the machine. If you’re running the machine and you lift the chuck guard, it functions like an E-Stop Button and shuts down the spindle.
Doors: All enclosed lathes have doors present that have to be closed in order to begin the operation.
Many of the same features can be found on the milling machines. E-Stop Buttons are present on all machines, as are guards, doors etc.
