With the emphasis on environmental protection, people are using more and more electric furnaces. This kind of heating furnace, which converts the electric energy in the furnace into heat to heat the workpiece, generally provides a molten metal for pouring in an industry. Compared with fuel furnaces, electric furnaces have more prominent advantages and help to alleviate increasingly serious environmental problems. Hengli can provide the main equipment-hydraulic system for various electric furnaces, provide power for various actuators, and precisely control the actuators to complete various actions. The tilting cylinder and the furnace door lifting cylinder provided as a set are customized for electric furnaces according to the needs of customers. The piston rod of the cylinder adopts a composite electroplating process, which improves the surface hardness, is not afraid of high heat, is more resistant to wear, and can increase the service life. And adopting high-temperature-resistant seal design to improve the durability of the seal. Hengli helps the continuous expansion of the application field of electric furnaces and is developing in the direction of times and high performance.
