Luoyang HongtengIntermediate frequency induction furnace
High heating speed, high production efficiency, less oxidation, and decarbonization, saving material and forging die cost. There is no need to worry about the waste of heated billets in coal furnaces due to power outages or equipment failures. Because of the fast heating rate, the oxidation is very small. Compared with the coal-burning furnace, the forgings per ton can save at least 20-50 kg of steel raw materials, and the material utilization ratio can reach 95%. Because the heating method is uniform and the temperature difference of the core surface is very small, the life of the forging die is greatly increased in forging, and the roughness of the forging surface is less than 50 um. Superior working environment, improved working environment and corporate image, pollution-free, low energy consumption. Induction heating its heat in the workpiece itself, so the heating is uniform, the core surface temperature difference is very small. The application of a temperature control system can achieve accurate control of temperature to improve product quality and qualified rate. The induction heating furnace has the advantages of small size, lightweight, high efficiency, excellent thermal processing quality, and a favorable environment. It is a new generation of metal heating equipment.
1. Electrical equipment, water cooling system, inductor copper pipe, and so on before opening, otherwise, do not open the furnace. 2. Furnace melting loss should be repaired in time. It is strictly forbidden to melt in the deep crucible 3. Power transmission and furnace opening should be responsible for special personnel after power transmission is strictly prohibited in contact with sensors and cables. Those on duty shall not leave their posts without authorization and shall pay attention to the external conditions of sensors and crucible. 4. When loading, check whether there are flammable, explosive, and other harmful items mixed in the charge. If it should be removed in time, it is strictly prohibited to add cold and wet materials directly into the molten steel, and the melting liquid is filled to the upper part. 5. It is strictly forbidden to mix iron chips and iron oxide when filling furnace and tamping crucible. 6. The pouring site and furnace pit should be free of obstacles, with no water, to prevent molten steel explosion. 7. Steel is not allowed to be filled too full, handbag pouring, two people should cooperate with the same, walking should be smooth, not to rush to stop,...
Intermediate frequency induction heating furnace adopts the principle of electromagnetic induction heating, with the help of inductors to generate an alternating magnetic field to generate the induced current of the same frequency, the use of the induced current in the workpiece distribution is not uniform, so that the surface of the workpiece is strong inside very weak, to the core is close to 0, so as to achieve the purpose of heating. What are the precautions in using the intermediate frequency induction heating furnace? Let’s take a look! Matters needing attention 1. If induction furnace should adopt special rectifying transformer to improve the supply voltage and limit the no-load operation of the transformer. 2. Standard installation, shorten the connection between high voltage, transformer, intermediate frequency power supply and electric furnace, select T2 copper material with high purity or oxygen-free copper, especially induction coil and water-cooled cable, increase its cross-sectional area can effectively reduce the current heat loss. 3. Select appropriate capacity and frequency intermediate frequency electric furnace according to the casting process, increase power density to improve melting efficiency, and reduce additional loss. 4. Give priority to steel shell furnace body with furnace cover to reduce heat loss and electromagnetic...
All along, The most troublesome thing for rolling product manufacturers is that the maintenance of rolling mill rolls, the main engine of rolling equipment, is the most troublesome. The accuracy of grinding, whether it has reached the scrapping standard, how to choose the compatibility of replacing supporting equipment, etc., have all become several major problems perplexing customers at present. If such problems cannot be solved in time, the losses and profits caused are immeasurable with the passage of time. First of all, let’s grasp the degree of roll grinding and the operation method, Due to long-term contact with the raw materials of tie products, It is bound to cause long-term friction and loss, Judging from the degree of tool setting of rolling mill rolls, If the conventional detector cannot detect it, High viscosity grease can be used, a layer can be applied, and then the grease on the surface layer can be scraped off to basically determine the problem. Secondly, the standard for scrapping is actually very vague. Under the condition that it cannot be repaired, the roller can be replaced. Finally, it is explained that the ideal production effect can be achieved only when the matching whole machine is...
In order to ensure the smooth production of the daily work of the rebar production line, daily maintenance is particularly important. It should be noted that the service life of the rolling mill will be greatly reduced if the daily maintenance of the rolling mill is not in place. Check the rolling mill every day for oil, water, gas leakage, and overheating; To reduce the loss caused by illegal operation of equipment or maintenance is not timely, the rubber roller should be lifted in the chain, rope, and roll surface end, etc. These are necessary maintenance measures. The automatic thickness control system on the rolling mill in the industrial production line is operated in strict accordance with the rolling mill operation process procedure and operation method. The gearbox maintenance should be cleaned at least once every quarter. When the roller-feeding steel reaches the limit position, special attention should be paid to the safe operation of the rolling equipment. When operating the rolling mill, attention should be paid to the hand being pressed by the steel plate and rolled into the feeding steel. When using the crane to lift the rolling mill for inspection, be careful not to collide with the...
In inquiries, customers often mention I want a 1-2T/H rebar production line to make 8-32mm steel bars. In fact, this is an unreasonable solution requirement. In reality, we would not design solutions for customers in this way. Because the steel bar production line below 5T /H usually using 40*40-60*60mm steel billets. Let’s take an example for the 60*60*1500mm steel billet, the weight of this steel billet is 42KG, and the weight of a steel bar with a diameter of 32mm and a length of 12M is 75.76KG. So this is the question: how do we use raw materials with a weight of 42Kg to make a finished product with a weight of 75KG? Obviously, it is impossible. Therefore, for production lines below 5T/H, the most recommended range for the production of steel bars is 12-22mm diameter steel bars. In addition, the size of the billet also affects the model of the rolling mill. The larger the billet, the larger the model and the more expensive the rolling mill is required. The steel bar production line is a very flexible production line. We can customize the plan according to customer requirements.
