The development of the press in the refractory industry can be summarized as the following stages:

Early stage (early 20th century to 1950s) : In this stage, the development of the press was relatively simple. It is mainly a double disk friction press type, which is used for simple forming and pressing of refractory materials. The press structure of this period is relatively simple, single function, Hualong's first generation of J58 double-disc friction press was born in this period.

Technology upgrade stage (1960s to 1980s) : at this stage, with the progress of science and technology, the press was upgraded in the refractory industry. The hydraulic system and control system have been improved, so that the pressure, speed and other parameters of the press can be more accurately controlled. At the same time, the structure of the press has gradually become more complex and stable, and Hualong has successfully launched the second generation of switched reluctance press through technological upgrading.

Automation stage (1990s to the beginning of the 21st century) : With the maturity and application of automation technology, Hualong HLDS hydrostatic servo electric screw presses realized automated production in this stage. Through the introduction of automatic control system and sensor monitoring system, the precise control of pressure, temperature, time and other parameters can be achieved to improve production efficiency and product quality.

High efficiency and energy saving stage (early 21st century to the present) : In recent years, the press has paid more attention to high efficiency and energy saving in the refractory industry. Hualong iot CNC press adopts new materials and new processes to optimize structural design and power transmission system to reduce energy consumption and material waste. At the same time, through the integration of intelligent control, data acquisition and analysis system, the equipment operating status monitoring and fault diagnosis are realized, and the stability and reliability of the equipment are further improved.

In general, the development of the press in the refractory industry has undergone an evolution process from simple molding to technology upgrading, to automated production and high efficiency and energy saving.
