Embodiment Construction
[0014] 1. According to figure 1 , figure 2 Complete the installation and debugging of slag detection and weight detection equipment;
[0015] 2. By controlling the sliding nozzle switch, and according to different molten steel flow rates, calculate the time required for the closing action of the sliding nozzle;
[0016] 3. According to image 3 Logic block diagram, PLC logic programming, complete slag amount and ladle weight detection and control.
[0017] A method for controlling and optimizing the remaining molten steel in ladle pouring of a casting machine, the steps of which are as follows:
[0018] Step 1. Install the slag amount and weight detection equipment on the large bag equipment, and set the slag amount value;
[0019] Step 2. When the actual value of the slag amount detection is greater than the set slag amount value, it is recorded as the first slag amount signal; after the first slag amount signal, the actual value of the slag amount detection is greater t...

The invention discloses a casting machine pouring ladle surplus molten steel control optimization method, which belongs to the technical field of casting machine detection and control. The invention is used to solve the problem that the molten steel in the ladle is in a vortex state during pouring production, and the greater the flow velocity, the larger the vortex. The specific measure of the present invention is that when the slag quantity signal comes for the first time, the closing action of the sliding nozzle is performed; when the closing action is completed, the state is maintained for 3 seconds, and then the sliding nozzle is opened. Through judgment again, the sliding nozzle is finally closed to complete pouring. According to the method provided by the invention, the pouring rate of the casting machine is increased by more than 10%, the consumption of molten steel on the production line is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of casting machine detection and control, and in particular proposes a method for controlling and optimizing the remaining molten steel poured in large ladles of a casting machine. Background technique [0002] During the pouring production process of the casting machine, the molten steel is injected into the tundish through the ladle equipment, and then flows into the crystallizer to achieve the purpose of pouring. There is a certain amount of steel slag in the molten steel in the ladle. When the pouring is close to the end, use the ladle slag detection equipment to detect the steel slag in the ladle. Once the steel slag is found to flow out, close the sliding nozzle under the ladle to avoid steel slag. The purpose of flowing into the crystallizer. However, it is found in actual production that through such process control, there is still a considerable amount of molten steel in the mixture of steel slag a...
