of Zhengzhou Dongsheng Metallurgical New Materials Co., Ltd. because of its uniform composition, low melting point, fast melting speed and shorter smelting time, which is attracting more and more attention of steel-making enterprises. It is known as a new type of material in the 21st century. It is mainly used for refining outside steel-making and metallurgical furnaces. Pre-melting multi-functional refining slag has been widely used in foreign countries, such as Korea, Japan, Europe and America, and has gradually attracted the attention and application of domestic metallurgical industry.
pre-melting refining slag refers to the use of high temperature in special equipment after mixing raw materials in a certain proportion. When the melting point temperature of slag system is higher than that of slag system, the raw materials are melted into liquid state, then cooled and crushed, and then used for steelmaking refining slag. The pre-melted refining slag has high purity, uniform chemical composition, stable phase, low melting point and fast slagging speed, which can greatly shorten the refining time and can be directly used for slag washing in ladle tapping process of converter to improve the cleanliness of molten steel. It does not contain fluorine or a small amount of fluorine. Because of its compact structure, non-water absorption, easy storage, non-pulverization and non-volatilization, it can significantly reduce dust pollution in iron and steel works, but the production cost is higher.
company produces pre-melted multi-functional refining slag which is melted by electric furnace, open-hearth furnace and cupola, with less impurities and stable composition. High calcium, high aluminium, high silicon and other products can meet the requirements of low sulfur, low carbon, low phosphorus and other indicators. Particle size is uniform and multi-functional, multi-functional refining slag features the same color.

deoxidizer is generally based on iron powder, used in general food, It can maintain food quality and prolong shelf life, prevent oil oxidation, fade and maintain nutrients in healthy food. Fresh-keeping applications in food are also very wide, mainly moon cakes, cakes, rice, miscellaneous grains, nutritious rice flour, oatmeal, butter products, all kinds of melon seeds, walnuts, amber walnuts, pistachios, dates, nuts, peanuts, fried peanuts, and more. Beans, fried beans, hemp, dried longan, lotus seeds, bread, crisp food containing nuts, pork and beef products, sausages, sausage, bacon, ham, laver, dried seafood, tea, tobacco, Chinese patent medicine and so on have become the most widely used advanced temperature preservation technology and reliable packaging technology in China's food industry.
When used, the fresh-keeping food and deoxidizer are put into the composite packaging bag with low oxygen permeability. When heat-sealing, attention should be paid to the sealing strength and quality so as not to leak air. Deoxygenation is suitable for the fresh-keeping of fatty and oily foods, but not for the fresh-keeping of products with high water content.
