Some knowledge about continuous casting cooling water

In the process of production, a lot of water will be produced. For example, if the cooling water is not properly treated in the actual operation, it will seriously affect the normal work. Therefore, we need to know some basic knowledge of continuous casting treatment, so as to meet the actual work needs.

Generally speaking, the treatment equipment of continuous casting cooling water is the crystallizer. The hardness (Ca+ ion concentration leading to scaling) and alkalinity of circulating water are continuously concentrated with the system circulation. When the pH value is high, it is very easy to scale, especially the temperature of crystallization equipment is relatively high, which is easier to form scale on the wall.

In order to accurately find out the appropriate scheme for scale and corrosion inhibition and flocculation treatment of continuous casting system, take purified water samples of crystallization equipment on site, screen a variety of compound agents through laboratory scale and corrosion inhibition experiments, hope to find a suitable high-efficiency scale and corrosion inhibitor for purified water, and conduct flocculation and sedimentation experiments on the water of turbid water system, Hope to find a suitable flocculant.

At the same time, it has been found in the practice of water treatment for many years that after the scale has appeared in the system, the direct addition of scale and corrosion inhibitor can only slow down the further growth of the scale, but can not eliminate the scale on the wall. The existence of the original scale, as the living point of the scale, is more likely to form scale than the smooth and clean metal surface. Therefore, it is decided to clean the current clean circulating water system first.

 

Generally speaking, using circulating water as industrial cooling water is an important way of industrial water saving. Due to the continuous concentration of solid solution, insoluble matter and metal scaling ions in circulating water, it often brings unforeseen harm to the system.

    In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
