Compared with traditional technology, hydraulic technology has the advantages of large transmission capacity and light weight, and can be applied to heavy, large and extra-large equipment. Therefore, it has an irreplaceable role in the metallurgical field and is widely used in metal smelting and Subsequent finishing process.



Application of Hydraulic Technology in Metallurgical Industry

1. Charging device on blast furnace roof

First of all, the hydraulically controlled material flow regulating valve bellless furnace roof can ensure a stable material flow, thereby ensuring high temperature and high pressure in the furnace and increasing production. Secondly, after adopting hydraulic technology for the opening and closing of the big and small bells on the furnace roof, the structure of the oil cylinder is more compact, and it can be better connected with the pull rod of the material bell, and the horizontal load on the furnace roof is eliminated, leaving only the vertical load. Thereby, the amount of steel required for the furnace roof can be effectively reduced. At the same time, the hydraulic technology is conducive to the control of the opening and closing speed of the material bell, and the impact on the hopper can be reduced by decelerating before the material bell is closed.

2. Applications in metal processing

In the metal processing industry, hydraulic technology can not only be used in various molding equipment, casting machinery, forging and welding equipment, but also in various metal cutting equipment.
In casting production, hydraulic technology is widely used in various equipment such as high pressure, injection molding machines, throwing presses, and die casting machines. In continuous casting, small continuous casting machines mostly use mechanical vibration, while large continuous casting equipment mostly uses hydraulic vibration due to their high precision requirements. The hydraulic vibration control technology realizes the vibration control of different waveforms by setting and modifying the waveform, amplitude and frequency online, so as to meet the requirements of the continuous casting production process.
