On the busy production line of a steel mill, another revolutionary technology developed by Lemu is quietly changing the traditional continuous casting production mode of this steel mill, helping the steel mill to achieve automatic blank production rate of more than 99% without manual intervention, and bringing significant benefits to the steel mill in terms of job optimization, energy saving and consumption reduction, waste optimization, intelligent scheduling, digital casting billet, etc., far ahead of other steel mills.

In the past, the continuous casting production line of the steel mill relied on manual operation, and the workers manually transported the casting billet, which not only had high work intensity, but also was inefficient, and the error rate was difficult to avoid. The disordered operation of the motor leads to the waste of energy consumption and the excessive loss of equipment. The information on and off the stage is not smooth, which also affects the smooth progress of production.

Since the introduction of the laser intelligent blank system, all this has changed dramatically. In the face of complex billet processes and changing equipment conditions, the intelligent billet system is like a smart butler, accurately controlling the fate of each billet.

The intelligent billet production system integrates the secondary system of continuous casting and the quality determination subsystem. At the same time, the cutting-edge technologies such as machine vision, intelligent sensors and AI intelligent control are used to realize the digital control of the billet through image acquisition and intelligent analysis. All kinds of sensors accurately control the positioning and transmission of the billet to ensure the intelligence and visualization of the production process.

The system brings 5 benefits highlights:

01

Position optimization

The transformation from multi-person collaborative work to one person monitoring greatly reduces labor costs.

02

Energy saving and consumption reduction

Rollers operate on demand, reducing energy consumption by 60%, and reducing spare parts consumption such as motors and rollers by 20%.

03

Rejection optimization

The system accurately locates the abnormal billet position, the accuracy is ±50mm, effectively reduces the cutting waste, and improves the billet yield.

04

Intelligent scheduling

To achieve intelligent scheduling for blank anomalies, the automatic utilization rate is as high as 99%, to ensure stable and reliable operation of blank.

05

Digital casting blank

The process parameters are bound to the corresponding position of the casting billet, all the process data of any section of the casting billet can be viewed at any time, and a unique code can be established for each casting billet. After cutting, the casting billet can be tracked in real time with the code, and the virtual number can be transmitted to the rolling steel, which can realize the visualization of continuous casting production and significantly improve the management efficiency.

Since the system went online, the production line of the continuous casting billet area of the steel mill has realized unmanned operation, and the intelligent level has been significantly improved: the production document is fully electronic, and the production data is visualized, which greatly improves the production efficiency and accuracy. The relevant person in charge of the steel mill spoke highly of the laser intelligent billet system: "The system not only improves our production efficiency and accuracy, but also greatly reduces the labor intensity of workers." We used to rely on telephone communication to estimate the location of the waste, but now the system can automatically guide the waste, which is very convenient!"

It is worth mentioning that the radium intelligent billet system can create millions of yuan of economic benefits for steel mills every year, and the investment cost can be recovered in just one year! At present, the system has been successfully applied in Chongqing Iron and Steel, Wuhu Xinxing Cast Pipe, Xinjiang Bazhou, Wuzhou Jinhai and other well-known steel mills and has been widely recognized.

In the future, we look forward to working with more steel mills to jointly promote the intelligent transformation and upgrading of the steel industry.
