Jianjie Industry Signs a Contract with Hubei Special Steel for RHF - rotary hearth furnace.Project-A Powerful Alliance to Shape the New Quality Productivity in the Binder Industry
Recently, Jianjie Industry and Hubei Special Steel have reached a landmark strategic cooperation on the RHF(rotary hearth furnace) dezincing and dust removal ash binder project. This move not only signifies the exceptional strength of both companies in their respective fields but also marks a significant step forward in promoting environmental protection, energy efficiency, and high-efficiency production. Through this powerful alliance, both parties are committed to enhancing the comprehensive utilization rate of energy processing, shaping “new quality productivity” in the binder industry.Firstly, the alliance aims to improve the comprehensive utilization rate. Steel enterprises produce a large amount of waste such as blast furnace gas ash, converter LT ash, and electric furnace dust during smelting production. These wastes, rich in elements like iron, calcium, magnesium, carbon, and zinc, are valuable renewable resources. However, directly recycling these wastes faces challenges likeRead 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 -

The Role and Application of Silicon Carbide Briquettes in the Steelmaking Industry
Silicon carbon briquette is an alloy composed of silicon and carbon, also known as high-carbon silicon, that is, ferrosilicon with a large carbon content. The silicon-carbon alloy is crushed and mixed with silicon powder and other raw materials according to the ratio, and silicon-carbon briquette binder is added, and pressed into a briquette shape to make it more in line with the steelmaking process .Silicon carbon briquettes made by adding silicon carbon briquette binders are one of the most widely used smelting materials at present, which can present a good property in deoxidation and inoculation, and can also be used as a reducing agent. It can optimize the quality of molten steel and improve the quality of products; reduce the amount of alloy added, reduce the cost of steelmaking, increase economic benefits, and reduce the labor intensity of workers.silicon carbide briquette :1. Deoxidation. The use of silicon carbon briquettes in the steelmaking industry can reduce the deoxidationRead more
