refining slag is related to the viscosity, surface tension and density of the slag, which is generally measured by foaming index. However, the determination of foaming index of the slag is based on experimental data such as a certain range of slag composition, a certain temperature and a certain blowing rate. These factors in actual production are constantly changing with the different refining requirements and production process. Fluorite has obvious influence on foaming effect. First, the surface tension and slag density are significantly reduced, which is beneficial to slag foaming; second, the slag viscosity is reduced, which is not conducive to slag foaming. Therefore, according to the slag used in actual production. Considering the comprehensive consideration and reasonable control of its adding time and dosage, the foaming of refining slag not only depends on the nature of the slag but also depends on the volume of the gas. Even if the slag is of good quality, the effect of producing foamed slag is not good because of the small amount of gas. In the middle and later stage of refining, because the oxygen in the slag has not been removed much, the effect of adding slag to the foaming of slag by adding calcium carbide or silicon carbide is poor. Foam properties can be made by adding limestone and a small amount of carbon powder to the foaming agent. Refining slag takes advantage of CO bubbles formed by reaction of CO2 and C to promote foaming of slag.
many people have looked at the basic uses of :
deoxidizer: as a new food preservation material, it has its unique advantages. The container is anaerobic and the food can be preserved. But the raw materials of deoxidizer must have stable reaction, no strange odor and harmful gas formation. In case of eating by mistake, it is harmless to human body. Generally, deoxidizer uses iron powder as basic material in general food, which can maintain food quality and prolong shelf life. It can prevent oil oxidation, fading and fading in healthy food. Maintaining nutrients. Deoxidizers have been widely used in wet bread flour, wet noodles, wet vermicelli, Wet snacks and semi-dry fish products abroad. At present, besides bagging, deoxidizers are also used in caps. Bags are used in bagged food, while caps are used in bottles, cans and other containers. In recent years, with the development of food industry and the improvement of packaging materials, deoxidizers have been paid more and more attention at home and are also used. More and more extensive.above "What's the advantage of deoxidizer production" is about the introduction, after reading our article, if you are interested in understanding, riser manufacturers and other more content, please click on our product list to see one by one.
