refining slag are related to the viscosity, surface tension and density of the slag. Generally, the foaming index is measured by the foaming index. However, the determination of the foaming index of the slag is based on a certain range of the composition of the slag. On the basis of experimental data such as fixed temperature and certain blowing speed, these factors in actual production are changing with different refining requirements and production processes, and the specific processes of each production unit are different. Therefore, the conclusions obtained have certain limitations in guiding actual production. The influence of fluorite on foaming effect is very obvious. One is to make the surface stretch. The force and slag density are significantly reduced, which is favorable for foaming of slag. Two, the viscosity of slag is reduced, which is not conducive to foaming of slag. Therefore, according to the slag system used in actual production, reasonable control of the time and amount of its addition will not only depend on the quality of slag, but also depend on the volume of gas. Even if the slag is of good quality, because of the small amount of gas, foam slag effect will be produced. The effect of adding calcium carbide or silicon carbide to foaming slag is poor. In order to improve the foaming performance of the slag in the middle and later stages of refining, the foaming agent added with limestone and a small amount of carbon powder can be used to refine and refine the slag. The bubble formed by the reaction of CO2 and C will be used to promote the foaming of slag.

deoxidizer: As a new material for food preservation, it has its unique advantages. It is packed in the same container as food. The deoxidizer absorbs the oxygen in the container, makes the container anaerobic and the food can be preserved. But the raw material of the deoxidizer must have stable reaction, no strange odor and harmful gas formation, in case it is harmless to human body. Using iron powder as basic material in general food can maintain food quality and prolong shelf life, prevent grease oxidation, fade and maintain nutrients in healthy food. Deoxidizer has been widely used in wet bread flour, wet noodles, wet pastries, semi-dry fish products and other foods abroad. At present, besides bagging, deoxidizer forms also include capping. In recent years, with the development of food industry and the improvement of packaging materials, deoxidizers have been paid more and more attention in China, and their applications have become more and more widespread.is good. About the advantages of Zhengzhou deoxidizer, let's talk about it today. If you have any questions, or for Zhengzhou Dongsheng Metallurgical new materials, there are limited.
