Continuous casting machine mold liquid level automatic pouring system

Technical background
Intelligent manufacturing has become a powerful engine to promote the quality and efficiency of iron and steel enterprises. The realization of one-button automatic pouring of crystallizer liquid level is an intelligent manufacturing symbol to improve the automation degree and production process level of continuous casting machines. Haineng Technology is currently a major technology company in China that provides a complete set of plug rods, automatic control systems for drawing speed and automatic pouring technology.

Advantages of automatic pouring system
On the basis of the existing plug rod type and drawing speed type liquid level detection and control system, the casting machine opening mode is upgraded and optimized, and the original manual opening mode is upgraded to the automatic opening mode. The biggest advantage of automatic opening mode is that after the pouring molten steel enters the crystallizer, the automatic opening mode is switched into the automatic drawing mode without interference, which increases the length of qualified cast billets and reduces the labor intensity of operators, reduce the leakage of steel, overflow steel accident rate, to ensure production at the same time improve the qualified rate of cast billet.
Hineng automatic open pouring system advantages:
● There is no need to change the size of the radioactive source rod for existing liquid level control;
There is no need to increase the dose of radioactive source;
● Only to make local changes to the mold, for the continuous casting machine to add automatic pouring function to save a huge amount of transformation costs.

System Introduction
● Pull speed type automatic pouring system
Based on the existing automatic control system of liquid level pulling speed of continuous casting machine crystallizer, the manual pouring mode of casting machine is promoted to the automatic pouring mode of pulling speed, and the one-key automatic pouring mode is realized by controlling the pulling speed to adjust the liquid level.

Composition of speed-drawing automatic pouring system

● Automatic plug-bar pouring system
Based on the existing automatic control system of the liquid level plug rod of the continuous casting machine mold, the automatic pouring system is added. By changing the automatic control program of the plug rod, the intelligent adjustment of the detection equipment, the plug rod equipment, the pulling and straightening system and the signals is realized, and the one-key automatic pouring mode is realized.

The composition of the plug rod type automatic pouring system.

comprehensive benefit
● Improve the quality of the head billet and economic benefits: Take 8 streams of 150 billet and 200 times of pouring per year as an example, compared with manual pouring, each stream can reduce the length of cutting waste head billet by 1.2m each time, and the annual total amount of scrap steel can be avoided by about 341 tons.
● Stable and rapid automatic pouring: realize stable pouring, and the automatic pouring is 40~50s faster than manual pouring.
● Reduce production and labor costs, reduce labor intensity and improve work efficiency.
● Reduce the accident rate of steel overflow from open pouring: precision calculation and failure chain are adopted for automatic open pouring to reduce the accident rate of open pouring by more than 99%.

Application example
● Qingdao Iron and Steel 150 Square Billet Continuous Caster has a new one-key automatic pouring control system, which has set a new high in the utilization rate and success rate of automatic square billet pouring in the country;
● The electric furnace plant of Nanjing Steel Works and Yunnan Xianfu Iron and Steel Group have respectively realized the function of automatic pouring, and have been unanimously praised by the above steel mills!
