After the successful development of the Automatic Stopper Rod Control System, Professor Tian Zhiheng once again made a bold move by applying electric cylinder technology to mold oscillation control.

At that time, hydraulic mold oscillation systems were already widely used in the steel industry. Theoretically, electric cylinder-based mold oscillation technology offered advantages such as higher precision, better synchronization performance, faster and easier installation, and reduced maintenance requirements.

However, no company in the world had ever applied this technology, and these theoretical advantages had not yet been verified through practical industrial applications.

At that time, Jiuquan Iron & Steel (Group) Co., Ltd. (JISCO) wanted to become the “first explorer” of this technology and launched a domestic bidding process for an electric cylinder non-sinusoidal control system.

Since RAMON’s electric cylinder Automatic Stopper Rod Control System had already been operating successfully at JISCO for more than one year, JISCO had a deep understanding of and strong confidence in RAMON’s electric cylinder technology.

After successful technical discussions and evaluation of RAMON’s electric non-sinusoidal solution, JISCO selected RAMON’s technology.

This became the world’s first electric cylinder non-sinusoidal control system.

Before the hot commissioning test of the electric non-sinusoidal control system at JISCO, RAMON engineers Xie Junhua, Chen Haiyun, and other project team members, together with engineering department personnel, stayed on-site for three months to complete the preliminary mold modification work.

The winter in Northwest China was extremely cold. Most members of the project team came from southern regions and had not brought down jackets, only thin sweaters. The harsh weather conditions created significant challenges for the team.

Despite the freezing environment, the team remained committed to their work, staying at the site and making thorough preparations to ensure the success of the commissioning test.

Just one night before the hot commissioning test, the technical team identified and eliminated a potential issue.

To ensure the test could proceed as scheduled, Professor Tian Zhiheng, Vice General Manager Tian Li, Chief Engineer Zhou Yonghui, and project team members held an emergency meeting overnight to discuss solutions.

Vice General Manager Tian Li personally participated in programming adjustments, while the chief engineer, project team, and engineering personnel worked continuously through the night and successfully resolved the issue before the test.

Although the process was challenging, the results were highly rewarding.

After RAMON’s electric non-sinusoidal system successfully passed the hot commissioning test on December 26, JISCO’s breakout problems were effectively resolved.

The warehouse that had previously been filled with spare parts became much more spacious. Due to the significant economic benefits created for the customer, the electric non-sinusoidal system was subsequently further promoted and applied at JISCO.

Today, the electric non-sinusoidal control system has become one of RAMON’s flagship products and has been successfully applied to nearly 600 continuous casting strands in steel plants worldwide.

Telling Our Story

Jia Huachuan, Director of Equipment Department, JISCO:

RAMON’s first slab electric cylinder non-sinusoidal control system was successfully applied at JISCO.

The system solved the instability issue of the oscillation table, increased casting speed, improved slab quality, and created significant economic benefits for JISCO.

We hope RAMON will continue to make further progress, explore cutting-edge technologies, develop more advanced products with higher technological value, and create greater contributions to China’s steel and metallurgical industry.
