Organic binding agent for pelletizing sintered pellets and adding device of organic binding agent

Abstract

The invention relates to the technical field of adhesives, and discloses an organic binding agent for pelletizing sintered pellets and an adding device of the organic binding agent. The organic binding agent comprises sodium carboxymethylcellulose, peridur, tackifier and an additive, and is characterized by comprising the following components of, by weight, 50-60 parts of the sodium carboxymethylcellulose, 1-2 parts of the peridur, the additive is prepared by mixing KMnO4 and K2Cr2O7, the additive is prepared by mixing the following raw materials of, in parts by weight, 2-5 parts of KMnO4 and 1-4 parts of K2Cr2O7. According to the organic binding agent for pelletizing the sintered pellets, the additive is added, the KMnO4 and the K2Cr2O7 in the additive are sensitive to the iron reaction, have excellent physical and chemical effects and can promote the oxidation of the Fe3O4, the saw-tooth Fe2O3 can be fully crystallized and rapidly developed into a large-interconnection crystal at a relatively low temperature, the problems of fine particles, poor connection and low pellet strength of the preheated pellet Fe2O3 crystal particles of the organic binding agent are solved, and the preheating and roasting strength of the pellets is improved.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an organic adhesive used for sintering pellets and its adding equipment. Background technique [0002] Pelletizing is a method of artificial block raw materials, and it is a process of changing powdery materials into physical properties and chemical composition that can meet the requirements of the next step of processing. During the pelletizing process, the material not only undergoes changes in physical properties such as density, porosity, shape, and mechanical strength of the size and phase due to rolling into balls and dense particles, but more importantly, chemical and physical and chemical properties occur, such as chemical composition, Reduction, expansion, high-temperature reduction softening, low-temperature reduction softening, melting and other transformation ratios improve the metallurgical properties of materials. So far, among the global iron ore resources, the p...

Problems solved by technology

Since the 1970s, the clinker feeding rate of key iron and steel enterprises in my country has reached 89%, which is comparable to that of some developed countries. Most of the adhesives on the market are not very viscous, which will cause cracks in the pellets. , pulverization and insufficient strength occur
