Adopt the molten steel large chartered car (high and low leg type) with weighing system;
The mold half-plate spring vibration device adopts double eccentric mold vibration;
Mould liquid level automatic detection and control system, eddy current sensor for liquid level measurement device, and stopper rod electric control system are adopted to ensure accurate measurement of mold liquid level, stable operation and improvement of the surface quality of casting slabs, with liquid surface drawing speed control mode;
The nozzle of the intermediate tank is equipped with a casting flow cutting device-driven by hydraulic pressure. In an emergency, the hydraulic cylinder is pushed to push the ram to cut off the nozzle and the steel flow to avoid accidents.
The 5-roller single-frame combined stretch-straightening machine has large blanking force, adopts perfect water cooling and lubrication system, compact structure, easy to replace, and improves the operating rate of the casting machine.
Adopt a rigid ingot bar system to simplify the structure of the guide section equipment, which is conducive to uniform cooling of the cast slab in the secondary cooling zone, improves the operation rate of the continuous casting machine and reduces the production preparation time of the continuous casting;
Automatic monitoring of crystallizer liquid level and stopper rod control
Maintaining the stability of the liquid level during the pouring process is a prerequisite for obtaining the best slab surface/internal quality. Automatic monitoring of the liquid level and monitoring of the stopper rod control mechanism-the control loop can keep the liquid level fluctuations in a small range under the condition of stable pulling speed, and at the same time, it can also improve the working conditions of the operators and eliminate the interference caused by the personnel. Breakout and other accidents.
Second cold water automatic control
Different specific water volume is set according to the cast steel type. During the pouring process, the secondary cooling water volume of each section is automatically controlled in sections according to a certain proportion and according to the change of the drawing speed to ensure uniform cooling of the slab in the cooling zone.
According to the change of the continuous casting machine process conditions, an on-line automatic adjustment of the water volume of each zone of the secondary cooling is adopted according to the change of the drawing speed, so that the surface temperature of the cast slab is controlled within an ideal range, and the surface temperature and liquid core of the cast slab are realized. Optimized control.
