An induction billet heater is a device used to heat billets, which mainly consists of induction coils, power supply, and control parts. It uses electromagnetic induction heating technology. When the induction coil is supplied with alternating current, an alternating magnetic field will be generated, causing eddy currents to be generated inside the billet, thereby heating the billet. An induction billet heater has the advantages of fast heating speed, high efficiency, energy saving, and environmental protection. It can heat the steel billet to the required temperature quickly, improving production efficiency. At the same time, due to the use of electromagnetic induction principles, the induction billet heater does not need to be in direct contact with the billet, reducing heat loss and oxidation. Characteristics of Induction Billet Heater Fast heating speed: Using electromagnetic induction heating technology, the heating speed is several times faster than traditional heating methods. Energy saving and environmental protection: Due to the use of electromagnetic induction heating technology, there is no need for direct contact with the steel billet, which reduces heat loss and oxidation, while also reducing energy consumption and environmental pollution. High-temperature control accuracy: Using an advanced temperature control system, precise temperature control can be achieved to...
A steel induction furnace is a piece of equipment used to heat and smelt metals. It uses the principle of electromagnetic induction to generate an alternating magnetic field through an inductor to generate eddy currents inside the metal, thus heating the metal. Composition Steel induction furnaces usually consist of the following parts: Induction Coil: The induction coil is the core component of the steel induction furnace. It generates an alternating magnetic field by passing in alternating current, which generates eddy currents inside the metal to achieve heating. Power Supply: The power supply provides alternating current to the induction coil to produce an alternating magnetic field. Control System: The control system is the command center of the steel induction furnace. It controls the frequency and power of the power supply, as well as parameters such as heating time and temperature according to production needs and process requirements. Cooling System: Since a large amount of heat is generated during the heating process, a cooling system is required to cool the equipment to avoid overheating and failure. The most commonly used is a closed cooling tower. Furnace Lining: The furnace lining is the supporting component of the steel induction furnace. It is made...
In the field of metal pressure processing, hot rolling causes plastic deformation of the metal through a rolling mill above the metal’s recrystallization temperature. The hot rolling process generally includes heating of raw materials, rolling of raw materials, cooling of finished products, and segmented packaging of finished products. Bar is a product of hot rolling. During the hot rolling process, bending will occur. Even after later straightening, it still cannot meet the requirements, resulting in batches of waste products. Causes of Bar Bending During Rolling Generally, the reasons for the bending of rolled parts are uneven cooling speed and inconsistent shrinkage during hot rolling; uneven heating temperature of raw materials; improper installation of rolling mill accessories during hot rolling, etc. At present, wire bar rolling control bending generally adopts online real-time control during the rolling process, such as adjusting the inlet and outlet guide devices of the rolling mill and optimizing the pass pressure configuration. However, due to the uneven temperature of the blank, the temperature difference between the head and the tail, and the uneven wear of the hole, the final control effect is not obvious. Solution There is a way to avoid bending of the bar during rolling....
An induction furnace for steel melting is a device that uses the principle of electromagnetic induction to heat and melt metal. It mainly consists of an induction coil, power supply, and furnace body. The induction coil is driven by the power supply to generate a high-frequency electromagnetic field, and the metal is heated and melted under the action of the electromagnetic field. Types of Induction Furnaces for Steel Melting Induction furnaces for steel melting mainly include the following types. Industrial frequency induction furnace: It uses an industrial frequency power supply for smelting. It is mainly used for smelting various cast iron and cast steel, mainly producing castings, with a capacity of 1.0~100t. Medium frequency induction furnace: uses a silicon-controlled frequency converter or frequency multiplier as the power supply to increase the frequency from 50HZ (60HZ) to 150~4000HZ. It is an important branch of the induction furnace and is mainly used for smelting special steel. The furnace capacity is 0.10~40t. Vacuum induction furnace: A furnace type that is smelted and poured in a vacuum. The power supply is similar to that of a medium-frequency induction furnace. It is mainly used for smelting special steel and alloys. The furnace capacity is 0.05~60t....
Metal casting involves injecting liquid metal into a mold to obtain a metal product in the desired shape. Metal Casting Methods In actual operation, metal casting methods include sand casting, investment casting, lost foam casting, metal mold casting, centrifugal casting, and pressure casting. These methods use gravity to fill the mold, and mold-making is a vital part of the entire production process. At the same time, due to the slow heat dissipation of the mold and the long cooling time, the casting production cycle time is also long. In addition, there is another metal casting method called continuous casting or strand casting. Continuous casting is to pour molten metal into the crystallizer of the continuous casting machine, and then continuously pull out the surface-solidified casting from the other end of the crystallizer. Continuous casting can produce billets or rods of any length. Sand Casting Process: Sand casting is a method of casting using a sand mold. The specific process needs several steps, including making a sand mold, injecting molten metal, cooling and solidifying, destroying the sand mold, and taking out the casting. Features: Sand casting has the advantages of low cost, short production cycle, and wide application range, but its...
With an aluminum melting furnace, we can frequently find a closed cooling tower. Apparently, we know what the closed cooling tower is used for. We just know it, but don’t know why and how it works. In this article, we will tell you there. A closed cooling tower is a type of cooling equipment. Its working principle is to ensure the cooling effect by utilizing the heat exchange between circulating air, spray water and circulating water. This type of cooling tower places a tubular heat exchanger inside the tower to achieve a cooling effect through heat exchange with air and spray water. Because it is a closed cycle, it can ensure that the water quality is not polluted, well protect the efficient operation of the main equipment, and improve the service life.
