Graphite electrode materials have the following six advantages

1、 Fast speed;Graphite discharge is 2-3 times faster than copper, and the material is not easily deformed. It has obvious advantages in the processing of thin ribbed electrodes. Copper has a softening point of around 1000 degrees, which is prone to deformation due to heating. The sublimation temperature of graphite is around 3650 degrees, and compared to copper, the thermal expansion coefficient of graphite material is only 1/30 of that of copper material;2、 Lightweight;The density of graphite is only 1/5 of that of copper. When using large electrodes for discharge machining, it can effectively reduce the burden on machine tools (EDM) and is more suitable for the application of large molds;3、 Low loss;Due to the presence of C atoms in spark oil, during discharge machining, high temperatures cause the C atoms in spark oil to decompose, forming a protective film on the surface of the graphite electrode, compensating for the loss of the graphite electrode;4、 No burrs;After the copper ele

Graphite acid method

The alkaline acid method includes two reaction processes: alkali melting process and acid immersion process. The alkali melting process is to chemically react with the acidic impurities in the molten and graphite under high temperature conditions under high temperature conditions, especially silicon -containing impurities (such as silicate, silicone aluminate, quartz, etc.) to generate soluble salt, and then Remove impurities after washing and improve the purity of

The Future Market Prospects of Graphite Powder

Graphite products manufacturers introduce the use of graphite block on cement back kiln in detail

The concrete flip kiln is the insulation machinery and equipment that conducts actual operation under negative pressure. The sealing situation on both sides is immediately associated to the production of cement clinkers, quality and energy consumption. In the work of improving and improving kiln heads and kiln tails, it is one of the effective ways to flip the high -yield and energy -saving of the kiln chemical plant. However, because the working conditions on both sides of the flip kiln are extremely high, not only the temperature is high, but also has flipping and shaking together. Therefore, the sealing work of the flip kiln chemical plant is both the key and difficult. Graphite block has the inevitable heat resistance characteristics and excellent authenticity characteristics, which can achieve a good regulation of flip kiln sealing. Therefore, in China, the graphite block has been used as a sealed material in the early 1950s. At this stage, the current stage. The use of use is st

What are the characteristics of graphite?

What are the characteristics of graphite? Graphite is a slot -type graphite dish, which contains one or several strips of two slot surfaces and bottom -end support points. The relative grooves of the hole, the respective design schemes of the relative two grooves are at least one exhaust pipe square groove, and the design scheme of each of the two -slot surface of the support point of the bottom support point has an corner slot. The design scheme below the highlight of the two neighboring W -shaped dual slots is based on the parallel surface of the slogan and cross -section of the design scheme.This utility model patent makes the hard alloy knife -shaped piece -shaped product in the process of boiling glue in the whole process of pillar opening and vacuum pumping. Technical majors make graphite and graphite products for customers. Welcome customers to visit everyone in person.

Graphite products can release far -infrared rays after heating.

Magnesium carbon brick -and -magnesium carbon resistance materials were in the middle of the age. It was successfully developed by the United States. In the age, the Japanese steel refining industry began to use magnesium carbon bricks in water cooling electric arc furnaces. Magnesium carbon bricks have been used in large quantities worldwide, and have become a traditional use of graphite. At the beginning of the age, magnesium carbon bricks began to blow the furnace lining of the oxygen top.Aluminum carbon brick and aluminum carbon resistance materials are mainly used for continuous casting, flag cover of flat steel billet transmission pipelines, underwater nozzles, and oil well explosion cylinders. Steel that is continuously cast in Japan accounts for above the total production volume.The molding and refractory 坩埚 of the relevant products and the fire -resistant 坩埚 and its related products, such as 坩埚, curly bottle, plug head and nozzle, etc., have high fire resistance, low thermal

Flake graphite processing

Flake graphite is obtained by mining and processing from graphite mines. The types of ore mined are different, and when processing flake graphite, it is also necessary to process it correctly based on the characteristics of the graphite ore. So how should we proceed with the operation? Let's have a simple understanding of flake graphite below.1. Mineral processing method for flake graphite cryptocrystalline graphite.Cryptocrystalline graphite crystals are very small, hence also known as microcrystalline graphite. Graphite particles are usually embedded in clay and difficult to separate. Due to the high grade of the raw ore (usually containing carbon), many graphite mines directly crush and process the extracted ore, selling graphite powder products.2. Mineral processing method for crystalline graphite in flake graphite.The natural floatability of crystalline graphite is good, and it is basically used in China. Due to the particle size of graphite sheets being one of its most important

Which raw materials are selected for the production of traditional carbon materials

Various metallurgical furnace carbon blocks (such as blast furnace carbon blocks, ferroalloy furnace carbon blocks, calcium carbide furnace carbon blocks, and aluminum electrolysis cell cathode carbon blocks, etc.) are used at a certain high temperature. Therefore, carbon blocks should have high mechanical strength, thermal stability, and corrosion resistance, but the ash content requirements are not too strict. Except for the bottom carbon blocks used in aluminum electrolysis cells, it is not necessary to measure conductivity. The production of carbon blocks mostly uses anthracite as the aggregate and metallurgical coke as the filling material. To improve the thermal conductivity and corrosion resistance of carbon blocks, a certain amount of graphite fragments (or natural graphite) can be added. In order to improve the thermal conductivity and conductivity of carbon blocks, semi graphite carbon blocks can be produced by electrocalcining anthracite.The raw materials used for conductiv
