Graphite crucibles play a vital role in various industries, including metallurgy, foundries, jewelry manufacturing, and more. These crucibles are essential for melting, casting, and refining metals at high temperatures. Classification of Graphite Crucibles: Crucibles can be categorized into three groups: graphite crucibles, clay crucibles, and metal crucibles. YIDA as a lesding Leading Supplier in China, specializes in manufacturing two types of graphite crucibles: machined graphite crucibles and graphite clay crucibles. Due to variations in performance, applications, and environmental conditions, the raw materials, production methods, technologies, and product specifications also differ. Natural crystalline graphite serves as the primary raw material for graphite crucibles, allowing them to retain the physical and chemical properties of natural graphite. These crucibles exhibit excellent thermal conductivity and high-temperature resistance. They have a low coefficient of thermal expansion during high-temperature applications and possess anti-strain properties in sudden cold and hot environments. Moreover, graphite crucibles demonstrate remarkable chemical stability in acidic and alkaline environments, showcasing strong corrosion resistance. With a wide range of sizes available, graphite crucibles are not limited by production scale, quantity, or smelting materials. They can be manufactured in any size and quantity while ensuring the purity of the smelting materials. As a result of their superior properties, graphite crucibles find extensive use in metallurgy, foundry, machinery, chemical, and other industrial sectors for smelting alloy tool steels, non- ferrous metals, and their alloys. They offer significant technical and economic benefits. Machined graphite crucibles Machined graphite crucibles, also known as high-purity graphite crucibles, are primarily machined using high-purity and high-density graphite materials, such as molded graphite material and isostatic graphite material. These crucibles are tailored to customers' specifications. Depending on the materials being melted, machined graphite crucibles can be further classified into steel melting crucibles, copper melting crucibles, gold melting crucibles, and analysis crucibles. Additionally, we can produce graphite arcs for various applications. Gold Refining Crucibles: Crucibles used for melting gold require raw materials with high purity and density. They should have a bulk density higher than 1.85g/cm3 and a total ash content of less than 50ppm. Gold melting crucibles are typically machined from high-purity, high-density, fine-grained graphite. The raw materials for these crucibles include molded graphite and isostatic graphite. Uranium Salt Refining Graphite Crucibles: These crucibles are large-sized graphite crucibles, commonly available in sizes such as Ф400mm × 700mm and Ф500mm × 800mm. The manufacturing process involves selecting high-quality, low-ash petroleum coke and then crushing, milling, blending, kneading, extrusion molding (or shaping), roasting, multiple impregnation, and graphitization purification. The primary raw material for these crucibles is isostatic graphite material. Graphite clay crucibles Graphite clay crucibles, also known as SiC graphite crucibles, consist mainly of silicon carbide (SiC) and graphite. They are primarily used for melting copper, aluminum, and other common metals. These crucibles have a relatively low cost and offer a large molten metal capacity. The main molding method for these crucibles is pressure forming. Important guidelines for crucible usage: Store the crucibles in a dry place to prevent exposure to rain. Before use, slowly bake them up to 500 degrees Celsius. The crucible should be filled based on its capacity, avoiding excessive pressure that could lead to metal cracking due to thermal expansion. When removing the molten metal, it is best to use a spoon and minimize the use of calipers or other tools. If tools are necessary, they should match the shape of the crucible to avoid generating excessive localized stress that could shorten the crucible's lifespan. https://www.yida-trading.com/

High-purity graphite refers to a form of graphite that has a high level of carbon content and a minimal amount of impurities. Graphite is an allotrope of carbon and consists of carbon atoms arranged in a hexagonal lattice structure. It is a highly versatile material known for its excellent thermal and electrical conductivity, low friction, and high chemical stability. The purity of graphite is determined by the amount of impurities present, such as ash, sulfur, nitrogen, and metals. High-purity graphite typically has a carbon content of 99% or higher, with impurity levels below 1%. The purification process involves various techniques, including chemical treatment, thermal treatment, and mechanical processing, to remove impurities and increase the carbon concentration. Apply to diamond bit and drilling tools with sintered mold etc.

Graphite For Continuous Casting refers to graphite products used in continuous casting crystallizers. Metal continuous casting technology is a new technology that directly forms molten metal through a continuous casting mold. Because it is directly formed without rolling, which avoids secondary heating of the metal, it can save a lot of energy. The characteristics of continuous casting graphite are: fine particles, uniform texture, high bulk density, small porosity and high strength Apply to metal continuous casting crystallizer, etc.

Graphite For EDM EDM graphite, also known as Electrical Discharge Machining graphite, refers to a specific type of graphite material that is widely used as an electrode in the EDM process. Why use graphite for EDM? Graphite has many advantages, making it the most widely used material for EDM electrodes: Resistance to Thermal Shock: Graphite has excellent resistance to thermal shock, allowing it to withstand the intense heat generated during EDM processes. This thermal stability ensures consistent performance and prevents cracking or damage to the electrode, even under rapid temperature changes. Low wear during sparking: Graphite exhibits low wear characteristics during the sparking process of EDM. This means that the graphite electrode experiences minimal erosion or degradation, resulting in longer electrode lifespan and reduced need for frequent replacements. Superior Machinability: Graphite is relatively easy to machine, allowing for the production of complex electrode designs with high precision. It can be readily shaped and machined into intricate geometries, enabling the fabrication of intricate and detailed EDM electrode profiles. Good Thermal Conductivity: Graphite exhibits excellent thermal conductivity, effectively dissipating heat generated during the EDM process. This feature helps to prevent excessive heat buildup, maintaining stability and prolonging the electrode's lifespan. Low Coefficient of Thermal Expansion: Graphite has a low coefficient of thermal expansion, meaning it undergoes minimal dimensional changes with temperature variations. This characteristic allows graphite electrodes to maintain their shape and size even when subjected to high temperatures during EDM processes. Excellent Geometric Stability: Graphite offers exceptional geometric stability during EDM operations. It retains its shape and form consistently, enabling the electrode to maintain the desired dimensions throughout the machining process. Lighter: It is five time less dense than Copper which means lighter electrodes. Graphite Grades and EDM Large grain graphite (about 20 µm) with low densities (1.76 g/cm3) Fine grain graphite (~10 µm) of high density (1.82 g/cm3) Very fine grain graphite (~4 µm) with densities greater than 1.86 g/dm3 Graphite grades can vary in terms of their grain size, which affects the material's performance during EDM. Fine-grained graphite offers higher precision and finer surface finishes, making it suitable for intricate and detailed machining operations. Coarser-grained graphite, on the other hand, provides better material removal rates and is often used for roughing operations.
