The process flow of carbon material production

The basic process of carbon material production includes: pre-treatment (pre crushing, calcination, or drying) of carbon raw materials, crushing, grinding, and screening grading of carbon raw materials, proportioning of carbon raw materials, addition of molten dehydrated binder and kneading, forming of paste after kneading, and roasting of formed green billets. In order to improve the density and strength of products, high-pressure impregnation and secondary roasting cycle densification treatment are carried out on the roasted billets, The graphitization of roasted products involves mechanical processing of carbon and graphite products.Why are the quality indicators of high-power and ultra-high-power graphite electrodes superior to ordinary power graphite electrodes?The current density of graphite electrodes used in high-power and ultra-high-power electric furnaces significantly increases, resulting in the following problems: (1) due to resistance heat and hot airflow, the temperature

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

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 is the heating principle of vacuum furnace heating graphite tubes?

The principle is to quantitatively inject the sample into a graphite tube using a sampler, and use the graphite tube as a resistance heating element. After being energized, the sample quickly heats up to achieve atomization. The heating power supply, maintenance gas control system, and graphite tube furnace are composed. An external power supply is added to both ends of the graphite tube to supply energy to the atomizer. The current flows through the graphite tube to generate a temperature of up to 3000 ℃, causing the measured element in the graphite tube to become ground state atomic vapor. The maintenance gas control system is used to control the instrument startup of maintenance gas, maintain the flow of Ar gas, and cut off the Ar gas flow after the air combustion is completed. The Ar gas in the external gas path flows along the outer wall of the graphite tube to maintain it from being burned, while the Ar gas in the internal path flows from both ends of the tube to the center of t

Scales graphite price tends to be stable

At the beginning of the month, the price of scales in Shandong was stable as a whole. At present, the mainstream price of -195 mainstream prices are 6300-6500 yuan/ton, which is the same as last month. Entering winter, most of the scale graphite companies in the Northeast are suspended for production holidays. Although a few companies are in production, the output is reduced and the inventory reserves are not much.The scale of the scale graphite market has been poor some time ago and the demand for material resistance has declined, which led to a decline in the price of scales, and corporate quotations were chaotic. As the Spring Festival holiday approaches, due to the suspension of production in the Northeast region, graphite supply has declined, and downstream enterprises have been basically completed. The supply demand for scales graphite market is plain, and the offer is relatively stable.In 2021, the export situation of scales was relatively sluggish. According to customs statist
