Corrosion prevention of pipes refers to the measures to slow down or prevent the corrosion and deterioration of pipes under the chemical and electrochemical action of internal and external media or the metabolic activities of microorganisms. Technical information A technique to protect pipelines from corrosion by soil, air, and transport media (oil, natural gas, etc.).The pipeline conveying oil and gas is mostly in the complex soil environment, and the medium conveying is also corrosive, so the inner wall and outer wall of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which will not only interrupt transportation, but also pollute the environment, and may even cause fire, causing harm. According to U.S. pipeline industry statistics, direct losses due to corrosion amounted to $600 million in 1975. Therefore, preventing pipeline corrosion is an important part of pipeline engineering. Introduction to the Corrosion can be understood as a chemical reaction of materials in their environment, which can cause the loss of pipeline materials and lead to the failure of pipeline components or even the entire pipeline system. Corrosion in a pipeline system is defined as chemical reactions, electrochemical reactions, and microbial erosion...
Induction melting furnaces used in industry include crucible furnace (coreless induction furnace) and melting trench furnace (cored induction furnace). The crucible is made of refractory or steel and has a capacity ranging from several kilograms to dozens of tons. Its melting characteristic is that they melt in the crucible is subjected to electric power, forcing the liquid level of the molten pool to bulge, and the melt flows from the center of the liquid level to the periphery, causing circular flow. This phenomenon is called the electric effect, which can make the melt composition uniform. The disadvantage is that the slag is biased towards the periphery and the coverage is poor. Compared with melt trench furnace, crucible furnace has a flexible operation, high melting temperature, low power factor, and high power consumption. The inductor of the melt trench furnace consists of an iron core, an induction ring, and a melt trench lining. The melt trench is one or two belt-shaped annular trenches filled with melt connected with the melt pool. In principle, the melting trench furnace can be regarded as an iron core transformer with only one turn of the coil in the secondary and short circuit. The induced current...
With the development of science and technology and the improvement of product quality requirements, many jewelry manufacturers and handicraft manufacturers have chosen medium frequency melting furnaces to smelt non-ferrous metals, and have achieved remarkable results. So, what are the advantages of medium frequency electric furnaces in metal smelting? The actual operation of the medium frequency smelting furnace is simple, and the temperature rises quickly, and it can be opened at any time. The application of energy consumption is reduced, which can ensure the control and smooth development of the whole melting process, and relieve the troublesome work of the workers in the melting furnace. The adoption of new technologies, new materials, and new processes has improved the performance and application effects of the medium frequency furnace, showing more and more vitality, and has achieved significant social and economic benefits. The medium frequency smelting furnace adopts an automatic frequency tracking system, and the frequency can be automatically adjusted with the load change without switching the capacitor. In recent years, the medium frequency furnace adopts KGPS induction heating device, which has high component density, outstanding performance, better start-up, more reliable use, simple maintenance, small footprint, and more advanced manufacturing technology. The furnace...
The most common fault phenomenon in the use of a medium frequency furnace is that it cannot start normally. The following list of common reasons and detection methods for failure to start: 1. Thyristor breakdown, multimeter measurement, resistance are almost zero. 2. If the water-cooled cable is broken, the two ends can be stripped and connected to the two ends of the cable. If it can be started, it indicates that the cable is broken. Attention should be paid not to pull high power to avoid unnecessary danger caused by burning off the power cable with a high current. 3. The intermediate frequency transformer burns out. Measure the resistance of 1000V gear, which should be around 70. 4. Intermediate frequency output sintering, because the intermediate frequency output line is too small, the power has been lost in heat energy. 5. The harmonic current resistance of the current transformer burns out. 6. There is a problem with the inverter pulse transformer. 7. If the electric heating capacitor burns out, remove the copper bar and check it with a 1000V insulation resistance meter or a multimeter to see the charging and discharging. 8. The smelting furnace passes through the furnace and measures...
The biggest feature of induction heating is to heat the workpiece directly. Its advantages are good working conditions, fast heating of the workpiece, easy temperature control, no metal impurities, and small metal burnout during the heating process, so it is widely used. The main disadvantage of induction heating is the complexity of the equipment. At present, induction heating is mainly used for quenching, diathermy, smelting, brazing, and sintering in the machinery manufacturing industry and metallurgical industry. 1) Quenching is to heat the workpiece to a certain temperature and then quickly cool it down, so that the metallographic structure of the workpiece is changed to a certain extent, thereby increasing the hardness and wear resistance of the workpiece. However, the workpiece becomes brittle after quenching, and the fatigue resistance becomes worse. In order to solve this contradiction, surface quenching occurs, that is, only the metal surface is heated (without heating inside), and then quickly cooled down. In this way, the metal surface is quenched and the hardness and wear resistance of the workpiece is increased. Maintain a certain strength. Induction heating is the most ideal heating method for surface hardening. Due to the proximity effect and skin effect, during induction heating,...
1. One set of power supplies is equipped with one furnace body. This method has no spare furnace body, low investment, small floor space, high efficiency, and it is suitable for intermittent production. 2. One set of power supplies is equipped with two furnace bodies. In this way, the two furnace bodies can work alternately, and they are on standby for each other. Generally, the foundry shops adopt this configuration. A high-performance high-current furnace change switch can be selected between the two furnace bodies to switch, making the change more convenient. 3. N sets of power supplies are equipped with N+1 furnace bodies. In this way, multiple furnace bodies share a spare furnace body, which is suitable for use in workshops that require mass castings. High-performance high-current furnace changer switch can be used to switch the power supply between furnace bodies. 4. One set of power supply is equipped with two furnace bodies with different capacities and different purposes, one of which is for smelting and the other is for heat preservation. The furnace body has different capacities. For example, a set of 3000kW power supply is equipped with a 5t smelting furnace and a 20t holding furnace. A high-performance...
