Luoyang HongtengIntermediate frequency induction furnace
Nowadays, more and more steel plants are focusing on hot rolling steel process innovation to improve production efficiency. Then, what is the hot rolling steel process? How does it work in steel plants? Today, Luoyang Hongteng will tell you the details. Steel ingots or steel billets with different chemical compositions and shapes into steels that meet the requirements of structure and performance need to go through a series of rolling mills. The combination and order of these processes are called process processes. Because there are countless varieties of steel and different specifications, steel types, and uses, the processes adopted by specific products are also different. The correct determination of the process is of great significance to ensure production, quality, and reduction of costs. The process of rolling production is quite complicated. Although with the improvement of the quality requirements of rolling products, the expansion of the range of varieties, and the application of new technologies and new equipment, the various processes of the process will change accordingly, the entire rolling production process is always considered by the following basic processes. Preparation Including the cleaning of surface defects, removal of surface iron oxide skin, and pre-heat treatment of the blank material....
How much it cost to produce a ton of steel is a question that every steel plant will pay close attention. Of course, everyone who wants to build a steel plant also wants to know the answer to this question. So, how much does it cost to produce a ton of steel? Is steel mill profitable? Now, Luoyang Hongteng will calculate for you in detail. Under normal circumstances, the construction of steel plants to produce steel factories will have the following costs: Venue and Equipment Cost, Raw Material Cost, Electricity Cost, Labor Cost and Environmental Protection Costs. Below, we will introduce one by one. Venue and Equipment Cost Building a steel plant first requires a venue. The size of the venue depends on the size and quantity of the equipment. The size and quantity of the equipment need to be determined according to the annual output. The smaller the annual output, the smaller the specifications of the equipment required, the less the quantity, and the lower the cost. Taking the equipment contained in the annual output of 100,000 tons of steel production lines as an example (covering an area of 50m*350m). Equipment Specification Quantity Induction Melting Furnace 3.5t 3 Continuous...
In lots of steel plants, the continuous billet rolling production line is the key equipment. It combines the continuous casting machine and the rolling mills to produce various types of steel products. Billet Continuous Rolling Production Line Production Process During the casting process, the casting temperature, casting speed and cooling water temperature restrict the quality of the billet. The temperature is too high or too low when the liquid steel comes out of the furnace, which is one of the reasons for the porosity and shrinkage cavity of the billet. Therefore, we should strictly control the temperature of molten steel when it comes out of the furnace. After crystallization, if the temperature of the sheared ingot drops too much, it needs to be heated with a medium frequency induction heating furnace. A temperature measuring point is set at the entrance of the induction heating furnace to monitor the temperature of the steel billet. We can adjust the cooling water temperature and water volume according to this temperature. Continuously hot-rolled steel billet have high plasticity and low deformation resistance, so larger deformation can be obtained with less energy. In rolling, the rolling temperature, the rolling speed of the continuous rolling mill,...
In the use of melting furnace, slag erosion is a common form of refractory damage. In fact, more than 59% of liner material damage is caused by slag erosion. In the process of melting, the furnace wall should be subjected to the impact force of the metal charge, the static pressure of the metal liquid, the electromagnetic stirring of the metal liquid movement, the thermal stress and other effects, which will affect the service life of the melting furnace lining. Therefore, the lining material should have a certain high temperature strength, no cracking and anti-erosion under the action of a variety of forces. In the melting furnace, the temperature difference between the inside and outside of the furnace wall is very large. About 10% ~ 15% of the heat is lost through the furnace wall. In order to reduce the heat loss and improve the thermal efficiency, the lining material should have low thermal conductivity. At the same time, the lining material should have a low conductivity, can not contain magnetic induction, especially the lining knotting process is not allowed to metal or strong conductivity substances in it. When the melting furnace is working, the temperature of liquid steel can...
Induction heating is a method of transferring heat energy. The principle of induction melting is that a high voltage supply from the primary coil induces a low voltage and a high current in the metal or secondary coil. Induction furnaces are well suited for melting and alloying many metals with minimal melt loss, but do little to refine them. Induction furnaces come in two main types: coreless and channeled. Some manufacturers of all kinds of demolition waste steel, industrial waste, copper, aluminum, stainless steel, idle equipment, plant demolition, scrapped cars, etc. If these scrap metals can be reprocessed and reused through special processes, the overexploitation of the earth’s minerals can be reduced. If we can reuse scrap metal, we can consume less energy in the process and better protect the environment. This is a very important opportunity for the development of a resource-saving green economy. For example, the customer has a lot of waste cans and aluminum castings, hoping to complete the resource re-integration of waste metal and aluminum through our equipment. We can design an aluminum ingot line production program for the user. In the program, we recommend the user to use an aluminum melting furnace to solve the...
How does an intermediate frequency induction furnace convert electrical energy into heat energy to heat metal during heating? Theoretically speaking, the intermediate frequency induction furnace heating process consists of two stages. The first stage: the alternating current of the frequency conversion device of the medium frequency induction furnace generates alternating magnetic field When the alternating frequency current of the medium frequency induction furnace passes through the spiral induction coil, a magnetic field is generated in and around the space enclosed by the coil. The polarity and strength of the magnetic field vary with the frequency of the alternating current. Part of the magnetic line of force penetrates the metal charge, and part penetrates the lining material. The polarity, intensity and rate of flux change of the magnetic field, that is, the direction of the magnetic field and the number and density of magnetic field lines, are determined by the intensity of the current passing through the induction coil, the frequency, the number of turns and the geometric size of the coil. The second stage: the alternating magnetic field of the frequency conversion device of the intermediate frequency induction furnace generates induced current A part of the magnetic field line penetrates...
