With the development of the world economy, the use of energy and raw materials is becoming more and more scarce, so many industrial applications have more energy-saving tools. So what are the application fields of induction heating, and the conditions of use involve several aspects? Let's learn about it with Kehua. Induction heating application field 1. Welding: cutting tools, drilling tools, knives, woodworking tools, turning tools, drill bits, brazing, reamers, milling cutters, drill bits, saw blades, frames in the glasses industry, steel pipes, copper pipes Welding, pick welding, welding of dissimilar metals, compressors, pressure gauges, contact points of relays, composite welding of different materials for stainless steel pot bottoms, welding of copper wires of transformer windings, storage (welding of gas filling nozzles, stainless steel meals, welding of kitchen utensils). 2. Heat treatment: quenching and annealing of mechanical metal parts (surface, inner hole, part, whole) such as gears, machine tool guide rails, hardware tools, pneumatic tools, power tools, hydraulic parts, ductile iron, automobile and motorcycle parts, internal parts, etc., stainless steel Pot products stretch. 3. Diathermy forming: standard parts, fasteners, large workpieces, small hardware, straight shank twist drills, overall and partial heat penetration and hot upsetting and hot rolling of twist drills, round steel with a diameter of less than 100mm, and metal materials Heating and annealing for stretching, molding, embossing, pipe bending, head smashing, steel wire (iron wire) heating nailing, stainless steel products annealing, stretching, expanding, thermal expansion, etc. 4. Other heating fields: heating lamination of aluminum-plastic pipes, steel-plastic pipes, cables and wires, metal preheating and plastic wrapping, semiconductor single crystal growth, heat-fitting, bottle-mouth heat-sealing, toothpaste skin heat-sealing, powder coating, Aluminum foil seals for metal implantation in plastic, food, beverage, and pharmaceutical industries. Induction Heating Equipment Technology - Annealing and Tempering Application of annealing to heat the workpiece to the appropriate temperature, using different holding times according to the material and workpiece size, and then slowly cooling (the slowest cooling rate), the purpose is to make the internal structure of the metal reach or close to equilibrium state, obtain good process performance and performance, or prepare for further quenching. Using induction heating instead of gas or furnace for preheating has several advantages. Heat transfer can be carried out directly, which will minimize heat loss and energy loss, increase production efficiency and improve product quality. At the same time, the heat can be precisely controlled, which can reduce the temperature during welding, thereby reducing the cooling rate. In addition, it is beneficial to reduce the risk of cold cracking and hardening. With induction heating, you no longer need to face the hot flames, which improves the working environment, reduces the need for cooling systems, and reduces the risk of fire. Induction heating application field using conditions The ambient temperature is in the range of 3-40 °C; (antifreeze measures should be taken in areas below 0 °C); the monthly average monthly maximum relative humidity in the area of u200bu200buse is not greater than 90%; there is no conductive dust or explosive gas around. and corrosive gases that can severely damage metals and insulation. Safe operation 1. Before opening the furnace, check whether the electrical equipment, water cooling system, sensor copper pipes, etc. are in good condition, otherwise it is forbidden to open the furnace. 2. If the melting loss of the furnace exceeds the regulations, it should be repaired in time. It is strictly forbidden to smelt in the crucible with excessive melting loss. 3. A special person should be responsible for power transmission and furnace opening, and it is strictly forbidden to touch sensors and cables after power transmission. Those on duty are not allowed to leave their posts without authorization, and pay attention to the external conditions of the sensor and crucible. 4. When charging, it is necessary to check whether there are inflammable, explosive and other harmful substances mixed in the charge. If it is, it should be removed in time. It is strictly forbidden to directly add cold material and wet material into the molten steel. After the molten liquid is filled to the upper part, it is strictly forbidden to add large pieces of material. , to prevent capping. 5. It is strictly forbidden to mix iron filings and iron oxides when repairing the furnace and pounding the crucible, and the pounding crucible must be dense. 6. The pouring site and the pit in front of the furnace should be free of obstacles and water, to prevent molten steel from falling to the ground and exploding. 7. The molten steel is not allowed to be too full. When pouring the hand ladle, the two should cooperate in the same way. The walking should be stable, and emergency stops are not allowed. 8. The medium frequency generator room should be kept clean, inflammable and explosive materials and other sundries are strictly prohibited from being brought into the room, and smoking is prohibited indoors. Induction heating application field Induction heating is an energy-saving and pollution-free technology. For this reason, it is widely used in the forging industry. This technology has been used in my country for many years. The above is the relevant situation of the induction heating application field analyzed by Kehua for everyone.
