Do you know anything about Zhengzhou Dongsheng Metallurgical New Materials Co., Ltd? Today, the small edition of Zhengzhou Dongsheng Metallurgical New Material Co., Ltd. gives you a detailed introduction about the limitations of refining slag. It also lets you know more about Zhengzhou Dongsheng Metallurgical New Material Co., Ltd.

refining slag's foaming performance is related to the viscosity, surface tension and density of slag. Generally, it is measured by foaming index. However, the determination of foaming index of slag is based on a certain degree. Based on the experimental data of the composition range of slag, a certain temperature and a certain blowing rate, these factors in the actual production are constantly changing with the different refining requirements and production processes, and the specific processes of each production unit are different. Therefore, the conclusions obtained have certain limitations on the guidance significance of actual production. The influence of fluorite on foaming effect is very obvious. The first is to reduce the surface tension and slag density significantly, which is beneficial to slag foaming. The two is to reduce the viscosity of the slag, which is not conducive to the foaming of the slag. Therefore, according to the slag system used in the actual production, reasonable control of the time and dosage of the slag is made. The refining slag is not foam, but it depends on the nature of the slag. It depends on the volume of the gas, even if the slag is of good quality, due to the volume of gas. In the middle and later stage of refining, because the oxygen in the slag has been nearly removed, the effect of adding calcium carbide or silicon carbide to produce foamed slag is poor. In order to improve the foaming performance of the slag in the middle and later stages of refining, we can use the foaming agent added with limestone and a small amount of carbon powder to refine the refining slag, and utilize the CO bubbles formed by CO2 and C to promote the foaming of slag.

deoxidizer is generally based on iron powder. It can maintain food quality and prolong shelf life. It can prevent oil oxidation, fading and maintain nutrients in healthy food. It is also widely used in food preservation, such as moon cakes, cakes, rice, miscellaneous grains, nutritious rice flour, cereal and cream. Products, melon seeds, walnuts, amber walnuts, pistachio nuts, red dates, nuts, peanuts, fried peanuts, green beans, fried beans, hemp, dried longan, dried litchi, lotus seeds, bread, crisp food containing nuts, pork and beef products, sausages, sausage, bacon, ham, seaweed, dried seafood, tea, tobacco, Chinese patent medicines, etc., have become the food industry in China. At present, the most widely used advanced room temperature fresh-keeping technology and completely reliable packaging technology for goods.

when used, fresh-keeping food and deoxidizer will be put into composite packaging bags with low oxygen permeability. When heat-sealing, attention should be paid to sealing strength and sealing quality, so as not to leak air. Deoxygenation fresh-keeping is suitable for the fresh-keeping of fatty and oily foods, and it is not suitable for water content bureau.
