Description

In the modern metallurgical industry, the stability of the molten metal level has a very large impact on the quality of the final product. Taking a cold-rolling galvanization production line as an example, a zinc pot is one of the most important equipment on the cold-rolling galvanization line, and has the function of generating molten zinc liquid, and the strip steel is annealed by a hot furnace and then enters the zinc pot for hot dipping, so that a metal protection layer is formed on the surface of the strip steel to protect a strip steel substrate. The stability of the liquid level of the zinc pot has great influence on the quality of products, for special steel types such as zinc aluminum magnesium and DP steel on a galvanizing production line, if the liquid level of the zinc pot is unstable to detect, the liquid level of the zinc pot is suddenly high and suddenly low, a grate and zinc slag in the zinc pot are attached to strip steel along with the fluctuation of the liquid level to generate zinc slag and zinc ash defects, the defect of scratch easily occurs in a zinc pot roller, and defective products easily occur, so that the liquid level stability of the zinc pot is an important control point of a galvanizing line process, is a key point for improving the quality of the production process, the defect of the surface quality of a galvanized sheet is paid attention to in production, and the stability of the liquid level measurement accuracy and the control accuracy of the zinc pot is important for improving the surface quality of the strip steel.
The existing liquid level control mainly has the following problems: 1. the control precision of the liquid level meter is not high, and the tiny change of the liquid level of the zinc pot can not be accurately detected. 2. When the dross on the surface of the zinc pot drifts from other positions to the position of the liquid level measuring point, frequent ingot adding is caused in a short time or no ingot is added in a long time, so that the liquid level is greatly fluctuated. 3. When the slag is fished out in daily life, the liquid level of the zinc pot is lowered more due to the fact that the zinc slag is fished out in the zinc pot, and the liquid level fluctuation is caused by interference to the liquid level measuring point during slag scooping.
