1.Product Introduction Furnace front manipulator is applied in the intermediate frequency induction furnace steelmaking workshop of the steel plant and is installed between the two furnace shells. It can easily compact the large volume of steel scrap or too loose light material when feeding, which makes the volume of steel scrap shrink rapidly and the compactness increases, thus improving the energy conversion and greatly improving the smelting efficiency of induction furnace. At the same time can quickly, flexible induction furnace around the scrap and packaging block sweep into the furnace. with remote control operation to keep the operator away from the furnace opening area and reduce the hidden danger of safety. 2. Main functions 1) a large volume of scrap steel or too loose and lightweight material that can be easily compressed into the material. 2) The volume of scrap is reduced rapidly and the compactness is increased; thus, the energy conversion is improved greatly Melting efficiency. 3) can quickly and flexibly sweep the scrap and packing blocks around the induction furnace into the furnace body, and solve the manual many, low efficiency, unsafe operation problems. 4) Instead of the original manual operation, it solves the high intensity labor under the high temperature environment (about 1500�°C temperature radiation), and realizes the remote control operation, which greatly reduces the casualties of the workers. 5) Rapid pressure reduction, so that the furnace phosphorus is not easy to produce high temperature, reduce the corrosion of quartz sand, greatly lift high furnace refractory life. 3. Advantages: the equipment has high quality and high reliability, stable and continuous operation. (1) The whole mechanism uses the hydraulic cylinder to drive the telescopic, lifting and rotating functions of the manipulator, the driving force is large and the operation is stable. (2) The front and end lever of the inner beam is designed as a fast-mounted structure, which can be replaced quickly. (3) The hydraulic components are concentrated in the rear of the equipment, which can keep away from the heat source and increase the reliability of the operation of the equipment. (4) Use local and remote control (remote control) two control mode, and can switch freely. Remote control operation can be free to shut down and emergency power cut off. (5) The equipment is small in size and takes up less space. 4.The equipment includes: manipulator body, hydraulic system, electric control system.

Three performance guarantee parameters:  Furnace temperature uniformity: ±3 Temperature control precision: ±1  Workpiece transfer time: 6-15s  Equipment Features A patented self-locking mechanism is adopted for the furnace door, ensuring that the furnace door will not descend by itself under any circumstances.  There is a flexible sealing connection between the furnace door and the furnace body; the furnace door is pneumatically compacted, ensuring the synchronous sealing performance of the whole sealing surface.  Each mechanical action is equipped with a perfect self-locking function, ensuring operation reliability and safety. Especially, there is a well-designed logical relation and reliable hardware-software logic interlocking circuit among the heating system, fan operation system, furnace door switch system, charging basket lifting system, water tank movement system and mixing system. They can keep the equipment and thermal treatment device safe in case a sequence error is caused by manual operation or a failure occurs in an action process during automatic operations.  High furnace temperature uniformity. A large-flow and high-air-pressure heat-resisting fan is adopted, able to generate enough recirculating air quantity and pressure; the super-large furnace consists of multiple temperature control zones including one main zone, ensuring that temperature rises synchronously in all of the temperature control zones; the all-fiber furnace lining minimizes heat loss, ensuring that the furnace chamber temperature gradient is within a certain range. High furnace temperature control accuracy. Multiplex control maximally ensures that the furnace chamber does not overheat, thus protecting workpieces from being softened and over-burnt.
Heating energy sources: natural gas, liquefied petroleum gas (LPG). An imported famous-brand automatic burner or gas burner is adopted, ensuring high heating performance, low noise and zero-discharge of fume, meeting the environmental protection requirements. After heating, the hot furnace gas is blown back to the upper mouth of the crucible through the flue; or preheated the combustion air from the flue heater ex-changer to improve the heating efficiency and reduce fuel consumption. Multiple safety protection modes are adopted, such as gas under-pressure, assisted gas under-pressure, flameout alarm and so on. Melting rate in a cold furnace: 3.5h Melting rate in a heated furnace: 2h
Usage Mainly used for maintaining temperature of molten aluminum alloys, suitable for all the crafting processes, such as pre-aluminum casting degassing, alloy preparation, uniform structure and temperature regulation and so on. â?¢ Energy source can be electricity and gas. Equipment Features â?¢Higher-quality molten aluminum can be obtained. Molten aluminum temperature accuracy, composition uniformity and less hydrogen content can be guaranteed. Flexible production organization. The crucible can be replaced at any time for production of different types of alloys, without contaminating the molten aluminum. Low burning loss of aluminum. The aluminum in the crucible is heated with heat conduction of the crucible, without local high temperature, reducing oxidizing loss and high-temperature volatilization, lowering the burning loss of aluminum to a level below 1.2%. The furnace floor is molded by monolithic casting with a casting material. Moreover, at the bottom of the furnace is a leakage outlet, through which the molten aluminum can outflow once the crucible is broken, reducing the risk of damage to the furnace body. The temperature of the furnace chamber and molten aluminum is controlled by series circuit, ensuring sufficient heating efficiency and preventing overheating of the furnace chamber. The molten aluminum thermocouple protect tube is made from silicon nitride, which is well heat-conducting, resistant to corrosion by the molten aluminum, resistant to thermal and cold shocks and highly strong. The tube can be directly immersed in the molten aluminum to measure its temperature. It has a service life of more than 2 years. Multiple safety protection modes are adopted, such as molten aluminum over-temperature alarm, furnace chamber over-temperature alarm and crucible leakage alarm and so on.
