Principle of Induction Melting There is no essential difference between using a pulsed magnetic field to heat a solid billet and melting metal for casting. The principle of induction heating described in this chapter still applies here. The pulsed magnetic field on the surface of the melt induces an induced electromotive force in the material, which then acts as a secondary short-circuited coil, causing current to flow in the metal and heat the metal. Except when the scrap steel is heated to the relative magnetic permeability of the Curie point, all concepts related to the skin layer depth can be used without restriction for the molten material. The advantages of induction melting are as follows 1. It can avoid the generation of undesirable metallurgical reactions such as oxidation and reduction reactions, and eliminate harmful gases and combustion products such as sulfur pollution. 2. Fast melting speed. For the same capacity, induction furnaces have a higher daily output than other types of furnaces. 3. The operating cost of the equipment is low, and its energy cost is as low as or slightly higher than that of high-efficiency fuel furnaces. 4. Improved working conditions, no large amount of heat loss and smoke...
Hongteng steel shell melting furnace have better stable and security function 2. Hongteng steel shell furnace structure is designed by computer simulation model, Furnace body tilting and hydraulic rod bearing are more reasonable. 3. Furnce energy saving 3%-5% than common furnace 4.Hongteng furnace top and bottom structure using High-temperature refractory cement integral pouring and molding, which is firm and durable. 5.The furnace mouth is made by steel, which is more durable than the traditional refractory brick and doesn’t need to replaced. 6. Hydraulic cylinder has a safety self-locking mechanism! which effectively prevents the furnace body from turning down due to the burst of the hydraulic oil pipe and increases the safety performance. 7. Steel shell furnace tilting system adopts double pumps and double motors, one for use and one for standby, thus effectively ensuring the operation efficiency. Hongteng steel shell furnace are energy saving, power consumption is 3%-5% lower than common furnace. 2.Hongteng brand furnace magentic yoke is made of high-quality cold rolled curved silicon steel sheet; Magnetic yoke coverage rate can reach 80%,means the magnetic conductors coverage, excluding fixtures. 1. Magnet conductor thickness only 0.23 mm,material cost 3885USD/T. Other brand furnace magnet conductor thickness 0.35-0.5 mm,material cost only 1328USD/T....
Medium frequency furnace system For many years, only medium frequency generator sets have provided medium frequency power, and these rugged devices have not yet been completely replaced by solid-state circuits. They are still used as induction heating power sources throughout the world. While thyristor inverters have entered the medium frequency power supply market in large quantities due to their higher efficiency, they should be carefully studied before discarding rotating electric machines. Foresighted users should consider the advantages of many years of trouble-free operation, low maintenance costs and good reliability of electric generator sets. The complexity of solid-state circuit devices themselves and their maintenance technology should also be carefully considered. In comparison, rotating generators only require routine maintenance of bearings by unskilled personnel. Even in the event of rare major failures, more than 40 years of experience should be the basis for evaluating equipment. The temperature of the workpiece heated by induction is measured in the conventional way, but with some important differences. That is, the temperature can be measured by either contact thermocouples or radiation pyrometers. However, some special problems are caused by rapid heating and factors such as coil windings and high electromagnetic fields.

Copper melting furnace Provides overall plant design for steel smelting, rolling, casting, forging, and heat treatment, as well as solutions for the recycling of scrap metal such as steel, copper, and aluminum. The main products are medium frequency melting furnace, medium frequency heating furnace, waste steel, copper, aluminum secondary melting furnace, molten steel refining and rolling, open and closed cooling tower, medium and high frequency surface quenching equipment, steel production line and other complete production line equipment. Copper and copper alloys are widely used in various fields of human production and life due to their excellent thermal conductivity, good processing formability, corrosion resistance and other advantages, becoming the third largest metal after steel and aluminum. With the development of science and technology and the increasing improvement of people’s material and cultural living standards, the application of copper and its alloys has become more extensive. As an ancient civilization, our ancestors have made historic contributions to the smelting of copper and the casting of copper alloys. The famous Yin and Shang bronze...
Furnace equipment users and industrial furnace technicians are not interested in the geological history of fuels or other heat sources. They are interested in the properties, use value and relative prices of various fuels. Furnace equipment The main properties of various commonly used gaseous, liquid and solid fuels are listed in the table. Because the composition of fuels is always changing, the values in the table are some average values. This chapter will also elaborate on the properties and use value of various fuels. An important property of fuel is the adiabatic flame temperature, that is, the temperature that the fuel should reach when it is burned in an adiabatic combustion chamber at a constant pressure with a theoretical amount of air at room temperature. Adiabatic flame temperature of different fuels under different conditions. In calculating the temperatures in these figures, the cooling effect caused by pyrolysis was not considered. For industrial furnaces, natural gas is now the most ideal fuel. Natural gas pipelines have been laid in industrial areas in almost every state in the United States. Generally, natural gas has a high calorific value, so it can be transported in smaller pipelines. Natural gas is very clean and...
Our factory’s shredders have many years of practical cases and supporting mature equipment. It is the core gathering place of shredder technology in China and even the universe. Yes, maybe you don’t understand this gold content. It is like the Silicon Valley of the United States, the hackers of Russia, and the coders of India. It is urgent to purchase Hongteng equipment. The fucking doorway to purchasing industrial shredders: the blood and tears lessons and practical parameters of old engineers 1. How to choose this broken thing? Seven critical truths of the industry veteran (pointing at the smoking machine in the workshop with a cigarette in his mouth) I have been dealing with scrap metal for 20 years, and I have seen too many bosses fall in the purchase of shredders. Last year, Russian Lao Zhang spent 800,000 to buy German products, but when he processed the chassis of electric vehicles, it was stuck like constipation-this is a typical selection error! 1. The bigger the torque of the blade shaft, the better The models on the market boasting 10000Nm are actually useless when it comes to processing aluminum alloy waste 304 stainless steel processing requires a dynamic torque range of...
