Where are the prices of high frequency heaters used?
When it comes to high-frequency heaters, many people may not be familiar with them. But it does apply to many aspects of life. High-frequency heaters are used in electric welding, induction cookers, etc. So what is he? What is the price of a high-frequency heater? Let's take a closer look below. High frequency heater price What is carbon fiber infrared? Carbon fiber infrared, as the name suggests, not only has the inherent characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. Compared with traditional glass fiber (GF), its Young's modulus is more than 3 times; compared with Kevlar fiber (KF-49), its Young's modulus is not only about 2 times, but also in organic solvent. , acid, alkali does not swell and do not swell, excellent corrosion resistance. Some scholars soaked PAN-based CF in strong alkali NaOH solution in 1981, more than 20 years have passed, and it still maintains the fiber form. The main method of producing far carbon fiber infrared rays is to select materials with strong heat exchange ability and emitting far infrared rays of specific wavelengths, and then process them into products of various forms and uses. The materials used in carbon fiber infrared products can effectively emit far infrared rays of 5.6um-15um, accounting for more than 90% of the overall wavelength. What is a high frequency induction furnace? High-frequency induction furnace is referred to as high-frequency furnace. High-frequency furnaces have been widely used abroad, and Kehua pointed out that domestic development has also been rapid in recent years. In addition to imitation products, fully localized high-frequency furnaces have entered the market and achieved good application results. High-frequency induction is an advanced heating method, because high-frequency power output is only available when the sample is burned. After the combustion is completed, the high-frequency induction stops. After the high-frequency furnace is started, no heating and preheating time is required, and the sample can be analyzed at any time. The high-frequency furnace has very excellent combustion performance, and the conversion rate of carbon and sulfur is higher than that of the tube furnace. The high-frequency induction furnace has a high melting rate, and the power can be kept in the best frequency band during the melting process, which greatly eliminates the adverse effect of the new lining on the melting speed; the quality of molten steel is high, and the yield of castings is high; During the operation of the whole machine, the power factor can reach more than 97% without interference to the power grid. The outstanding advantage of high-frequency furnace is its strong adaptability to samples, especially for tube furnaces, special materials that are difficult to burn in electric arc furnaces, such as stainless steel, high chromium, high manganese steel, electrothermal alloys, master alloys, pure metals (Ni, Co, Cu, etc.), ferrosilicon, ferrochromium in ferroalloys, ore, slag, sinter, oil shale, graphite, tungsten carbide, rare earth materials and various non-metallic raw materials, etc., all have good combustion effects. The high-frequency furnace has stable combustion performance, convenient operation and high degree of automation, such as matching with infrared analyzers. Accurate and reliable carbon and sulfur analysis results will be obtained. In 1989, high-frequency combustion-infrared absorption method was listed as ISO standard (ISO9556-89, ISO4935-89), which shows the high reliability and technological leadership of this method. Application of high-frequency heaters Edit Induction heating can be used to heat some objects in specific parts, and can be used in surface hardening, melting, brazing, soldering, and heating objects to cooperate with other objects. Iron and steel respond best to induction heating because of their ferromagnetic properties, but any metal will generate eddy currents due to induction heating, and magnetic materials will experience hysteresis. Induction heating has been used to heat liquid conductors (eg molten metal) and plasma conductors (eg induction plasma technology). Induction heating can also be used to heat graphite crucibles (where other materials are placed), widely used in the semiconductor industry to heat silicon or other semiconductor materials. Grid frequency (50/60Hz) induction heating is commonly used in many low-cost industrial applications because it does not require additional inverters to generate alternating currents at other frequencies. High frequency heater price Induction furnace Induction furnace uses induction to melt metal. After melting, the high-frequency magnetic field can also agitate the metal, ensuring that the added metal and the original metal are fully mixed when making alloys. Most induction furnaces consist of a water-cooled copper ring encased in a heat-resistant material. Induction furnaces are more environmentally friendly than reverberatory furnaces and blast furnaces. When melting metals, they have replaced these two production methods and become a clean production method commonly used in modern factories. The amount of heatable metal varies from one kilogram to hundreds of metric tons. During operation, induction furnaces are likely to have a high-frequency humming sound, which varies according to their operating frequency. Metals that can be processed include iron and steel, copper, aluminum and precious metals. Because induction furnaces are clean, non-contact processes, they can be used in vacuum or in an inert gas environment. Some special steels or alloys are oxidized when heated in air, and such alloys or steels can be produced by vacuum electric furnaces. Induction welding Induction welding is a processing method similar to an induction furnace, but on a smaller scale. If ferromagnetic particles (the characteristic of hysteresis in the material generates heat during induction) or metal particles are added to the plastic, induction welding can also be used for welding. The gap of pipe fittings can also be welded in this way. The electric current introduced near the gap heats the material, resulting in a high temperature that can be welded. At this time, the materials on both sides of the gap will be forced to approach each other, and the gap will be welded. Electricity can also be conducted into the pipe with a brush, but the result is the same, the material of the gap attachment heats up and welds. Through the above introduction of Kehua, we have a general understanding of the price of high-frequency heaters and where they are applied. It seems that high-frequency heaters have indeed played a great role in our lives. If you want to know more about it, please pay more attention to us.
