2022-11-22Carbon felt is a major element in many alloy products, so carbon felt purification plays an important role in alloy production. Meanwhile, in the smelting process of metal silicon, silica, ore, etc. are usually used. Silicon slag will also be produced during the smelting process, and silicon slag also contains a certain amount of industrial carbon felt, so we can use carbon felt slag to further purify carbon felt.The first step is to separate the obvious light-colored slag and dark-colored slag from the silicon slag with a manual hammer, and then use the separation principle to further separate the silicon content in the silicon slag.Impurities in silicon slag exist in two forms: reduced and unreduced. In industrial silicon, a flocculant composed of Na2O5~50%, SiO250~95% or Na2O5~50%, SiO250~95%, MgO and CaO is added to industrial silicon. With 35% flux, the melting point of the slag can be reduced from the original 1450 to about 1480 and then down to about 1000. It can also reduce th
2022-11-22Carbon felt purification is widely used in actual industrial production. At the same time, everyone also found that carbon felt purification has many colors, and different colors have different characteristics and different applications. But carbon felt is a sewage crystal, and the color of carbon felt mainly depends on the loyalty and quantity of impurities in the crystal. The abrasive industry considers light blue to black as black carbon felt; colorless to green as green carbon felt.There are several explanations for the color of carbon felt. It is generally believed to be caused by the presence of foreign impurities. For example, when boron is introduced in the form of boron carbide, the crystal turns black; when the crystal contains nitrogen, it becomes green.The appearance color of carbon felt is not only related to the color of the crystal itself, but also related to the interference phenomenon of natural light on the crystal surface. When the thickness of the silicon oxide fil
2022-11-19Silicon carbide has a wide range of uses in industry. Silicon carbide has high hardness and good thermal conductivity. It is a semiconductor that resists oxidation at high temperatures. Although it has many uses, it is not clear to those who have not been exposed to it.1. Application in non-ferrous metal smelting industryThe use of silicon carbide has the advantages of high temperature resistance, high strength, good thermal conductivity, and impact resistance. It is used as a high-temperature indirect heating material, such as solid tank distillation furnaces, rectifier furnaces, aluminum electrolytic cells, copper melting furnace linings, and zinc powder furnaces. Use arc plates, thermocouple protection tubes, etc.2. Application in steel industryTaking advantage of the corrosion resistance, thermal shock resistance, wear resistance, and good thermal conductivity of silicon carbide, it is used in the lining of large blast furnaces to increase the service life.3. Application in metall
2022-11-19Silicon carbide is widely used in industry and plays an important role. Silicon carbide can also be used as an abrasive, so the quality of silicon carbide particles is particularly important. We want to test its quality, so how to test its quality?Before proceeding to the analysis, the first thing we need to understand is that the abrasive is not only composed of particles of one shape, but only depends on the percentage of that shape. When analyzing the shape of abrasive grains, it can also be seen that the edges of the abrasive grain surface have characteristics such as smoothness, sharpness, rounded corners, straight lines, serrations, and cracks.Impurities are often mixed into the grinding powder. One is the components contained in the abrasive grains themselves, which are mainly formed during the smelting of raw materials, such as iron oxide, silicon dioxide, chromium oxide, and sodium oxide. Another kind of impurity is dissociated between particles, mainly iron filings and dust
2022-11-22Graphite has a wide range of applications, and many products in our lives are inseparable from its role. We have also learned some basic knowledge of graphite before, and have a simple understanding of its application fields. We know very little about graphite. Only with more knowledge about the product can we apply it better in the future. The following is the graphite knowledge introduced by graphite manufacturers.Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, graphite has many other uses besides abrasives. It is an excellent deoxidizer and can accelerate refining. The tapping speed is fast, the chemical composition is easy to control, and the quality of the steel is improved. Graphite powder is coated on the inner wall of the turbine impeller or cylinder through a special process, which can improve its wear resistance and prolong its service life. Furthermore, graphite is a semiconductor due to its high
2022-11-22Graphite occupies an important position in the industry, and because of its good performance, graphite is widely used in many industries, and its use effect is good, so it is loved by users. Some basic knowledge of graphite must be known to everyone. The following is the development history of graphite. Presumably very few people know this. So today, let us take a closer look. The following is the introduction made by graphite manufacturers.Graphite is a kind of carbide accidentally discovered in the laboratory by Acheson of the United States in 1891 when he was conducting molten diamond experiments. At that time, it was mistaken for a mixture of diamonds, so it was named emery. The industrial method of smelting graphite, also known as the Acheson furnace, is still in use today. The electric resistance furnace with carbonaceous material as the furnace core generates graphite by heating the mixture of quartz SIO2 and carbon.Several events about graphiteGraphite was first discovered in
