What are the advantages of Jianjie pellet binder compared with bentonite??
Jianjie pellet binder is a mixture of multiple environment-friendly polymer materials. It not only improves the viscosity and water absorption of bentonite itself, but also improves the bonding strength and compressive strength, reduces the dosage of bentonite, and enhances the quality of the pellets.Advantages are as followed:(1) Less dosage, high bonding force, high forming rate, good compressive strength of green ball, high shatter strength, and improve the grade of pellet ore.(2) Accelerate the speed of pellet formation, so that the pellets surface is smoother, in more uniform size, and good thermal stability, which is more suitable for steel making.Besides,they will have no affect on the burst temperature.(3) Roasted pellets: the cold strength of the roasted pellet ore is higher, especially the cold strength of the low-temperature roasted pellet ore increases more. It improves the metallurgical properties of pellet and the high temperature resistance of pellets, reduces the roastiRead more -
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 -
Discussion about Blast Furnace Briquettes
In the steel making process, cold pressing technology is often used to recycle solid wastes, many of which, such as iron oxide, iron sludge, and iron dedusting ash, are cold pressed and reintroduced into converters and electric furnaces as slagging agents and coolants in the steel making process. Recently, some steel mills use the red mud produced in the alumina manufacturing process to make cold pressed pellets, which can be used as dephosphorising agent in the steel making process.The utilization of red mud as a dephosphorising agent in the steelmaking process stems from its unique chemical composition. With high levels of Al2O3 and Na2O, red mud plays a pivotal role in facilitating the formation of a primary slag with favorable melting properties and fluidity during steelmaking. This initial slag environment creates optimal conditions for deep dephosphorisation reactions, thereby enhancing the efficiency of phosphorus removal in the early stages of steel production.Internationally,Read more -

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
