Bauxite Residue (red mud) Briquettes to Use in Converter as Dephosphorising Agent and Flux
Red Mud Cold Press Briquettes as a Revolutionary dephosphorisation Solvent in Converter OperationsBauxite residue, also known as red mud, is a byproduct generated during the extraction of alumina (aluminum oxide) from bauxite ore using the Bayer process. Bauxite residue consists of the insoluble materials that remain after the extraction of alumina from bauxite through the digestion of crushed bauxite in sodium hydroxide solution, followed by precipitation of aluminum hydroxide.Some steel plants use red mud to make briquettes, and use those briquettes in converter as dephosphorisation agent, in this process,perfectly solved the problem of recycling of bauxite residue.The common standard of this briquettes is: green briquettes falling from 1.5 meters without breaking,and dry briquettes need to resist 500N.In this process,we perfectly solved the space occupancy issues of such metallurgical waste,and more economic value generated.The Role of Red Mud Cold Press briquettes: Red mud cold preRead more -

How to Dezincify and Reuse Dedusting Ash in Steel Plant Dezincification Bunder
In the process of steel making,there will be a large amount of dedusting dust, and a considerable part of the steel plant reuse it as raw material for the sintering system. However, due to the large amount of K, Zn and other elements in the dedusting ash, it will severely damage the corresponding equipment.Cold-pressed briquettes by dezincification binder enable zinc recovery in multiple processesProcess Flow for Extracting Secondary Zinc Oxide from Dedusting AshWet process and dry process are commonly used. The dry process accounts for more than 80% of the current domestic production of sub-zinc oxide.Rotary Kiln Fuming MethodZinc-containing dedusting ash is used as the main material, coke powder is used as the combustion raw material, and dezincification binder is added in a certain proportion. After mixing and forming, it is transported to the kiln for high-temperature calcination, and the furnace material is continuously turned and rolled.When the temperature in the kiln is about 1Read more -
After Signing a Contract for 10 Billion, an 80 Million Ton Steel Plant Lands in Tangshan
On May 4th, Tangshan City Party Secretary Wu Weidong visited Qianxi County to conduct research and inspections on project construction and other work. He emphasized the need to accelerate the implementation of the signed cooperation agreement between China Oriental Group and ArcelorMittal Group, and to explore the development of a fusion development industrial park combining Jinxi Steel and ArcelorMittal Group.It is reported that on April 24th, the 70 ArcelorMittal New Energy Soft Magnetic Material Project was officially signed in Changzhou, with a project value of 10 billion yuan. As of the end of 2022, ArcelorMittal's crude steel production capacity was approximately 82.1 million tons.The new 80 million ton steel plant in Tangshan, which follows the 10 billion yuan contract, marks a significant milestone in the strategic partnership between China Oriental Group and ArcelorMittal Group. The joint venture, which will be located in Qianxi County, Tangshan, is expected to bring significaRead more -

RDI(Reduction Degradation Index) and Blast Furnace Yield
RDI—-Reduction Degradation Index.Raw materials (especially sinter ore) in BF production process will be severely broken and Pulverized when reduced in the low-temperature zone in the upper layer of the blast furnace, which will reduce the porosity of the column and deteriorate the gas permeability.For every 5% increase in the RDI, the blast furnace output will decrease by 1.5% and the CO utilization rate will also decrease. the level of RDI is related to the type of ore powder used in the sinter production. The sintered ore produced from rich ore powder has a high RDI, the sintered ore produced from concentrate powder with high TiO2 content also has a high RDI, while the RDI is low when magnetite concentrate powder is used. The way to reduce RDI is to try to reduce the number of sintered ore RDI caused by the elevation of the skeletal crystalline rhombic hematite, can be appropriate to increase the FeO content or add halide CaF2, CaCl2, etc.. Many enterprises spraying 3% halide solutioRead more
