Silicon-manganese alloy briquette is an indispensable composite deoxidizer in the steelmaking process. Its chemical composition is FeMn58Si14. It is formed into a spherical block after special processing of silicon-manganese and various materials including binders. It has the effect as silicon- manganese bricks. It can reduce the amount of ferrosilicon and silicon manganese used in steelmaking alloys, and has a wide range of applications in the field of steelmaking.Briquette composed of manganese, silicon, iron and a small amount of carbon and other elements , which are cold-pressed after adding binder . Since manganese and silicon are the main alloying elements used in carbon steel, and almost all steel types require manganese for deoxidation, silicon-manganese alloy briquettes are also a commonly used deoxidizer in the steelmaking process.Manganese is added into molten steel as an alloying element to produce alloy steel, thereby improving the mechanical properties of the steel and inRead more -
Do You Know the Role of Silicon Carbide Binder?
The more common silicon carbide in the market mainly includes black silicon carbide and green silicon carbide. Black silicon carbide contains about 95% SiC, and its toughness is higher than that of green silicon carbide. It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. Green silicon carbide contains more than 97% SiC and has good self-sharpening properties. It is mostly used for processing hard alloys, titanium alloys and optical glass, and is also used for honing cylinder liners and fine grinding high-speed steel tools. Generally, silicon carbide with a relatively fine particle size of 0.5-3 mm is used in an electric furnace . Add silicon carbide binder to make briquettes and then use them in the furnace, which is easy to melt and absorb. When used in a cupola , the particle size will be required larger silicon carbide , so as not to be washed out by strong air currents. In addRead more -
The Role and Application of Silicon Carbide Briquettes in the Steelmaking Industry

Deoxidation. The use of silicon carbon briquettes in the steelmaking industry can reduce the deoxidationRead more -
The Key Role of Coke Powder Binder in the Recycling of Pulverized Coke Part two
Compared with carbonization (bitumen) and humic acid, our pulverized coke binder technology has obvious advantages:1. High strength: This technology uses ordinary briquetting machine, and our pulverized coke binder is added in the process. The cold strength is generally 65--100 kg/briquette, and the hot strength is generally up to 130kg-160kg/briquette. Higher can reach 200~250 kg/briquette; high temperature resistance is around 1200-2050 degrees.2. The production process is short: our pulverized coke binder and coke powder are mixed in proportion, fully stirred evenly, extruded by a briquetting machine, and then dried to form a coke product, and pitch is used as a pulverized coke binder Bonding requires heating, forming, carbonization and other processes to form coke, and the cost of forming coke is 2-3 times higher than that of this technology.3.Environmental protection and pollution-free. Jianjie Group's pulverized coke binder technology produces coke, from stirring, molding to dryiRead more -
The Key Role of Pulverized Coke Binder in the Recycling of Coke Powder Part one
Coke is an extremely important industrial resource, widely used in metallurgy, chemical industry and other fields, but coke will produce a small amount of powder during coke breaking, transportation and use. In the process of producing finished products in coking plants, the transmission process of steel plant conveyor belts A certain amount of powder will be produced in the process, and the recovery of these powders requires the use of pulverized coke binders. It is reported that the coke powder produced in these processes accounts for about 20% of coke every year. Most of these coke powders are used to make coal for power generation, and the other part is piled up randomly, which not only wastes resources, but also pollutes the environment. With the increasing demand for coke and the increase of coke resources (coking coal), the carbon-to-steel ratio generally used in steelmaking in steel plant is 1:2, and the consumption of coke is large. How to fully and effectively apply coke powdRead more -
Coal Briquetting Binder - the Best Partner to Improve Pulverized Coal Molding
As the degree of coalification increases, the plasticity of coal decreases rapidly, and the formability resistance changes. For coal with a high degree of coalification, it is generally necessary to add a viscous agent to increase the plasticity of the coal before it can be formed.1. Shape characteristics of coalThe forming characteristics of coal is an important internal reason affecting the forming process of coal powder, especially the elasticity and plasticity of coal are more prominent. The plasticity of coal is higher and higher, and the formation of coal dust is more typical.2. Molding pressureWhen the forming force is less than the pressure crushing force, the mechanical strength of the formed coal increases with the increase of the forming pressure. Different types of coal have different crushing forces. The pressure is closely related to the type of coal, the combination of moisture and particle size of the material, the type and quantity of the binder, etc.3. Material moistuRead more -
Binder for Briquettes of Phosphorus Ore Powder, Saving Cost and Improving the Utilization Rate of Phosphorous Powder
Phosphorous powder, gray or brown, has no smell. The main component is fluorapatite (chemical formula, Ca10(PO4)6F2), containing 10-35% of total phosphorus (phosphorus pentoxide), of which 3-5% phosphorus is soluble in weak acid and can be absorbed and utilized by crops. Other large Some crops are difficult to absorb and utilize directly, and belong to insoluble phosphate fertilizers.In recent years, there has been a shortage of phosphate rock resources. The output of phosphorous powder brought by phosphate rock mining is large, and the excess phosphorous powder will take up a lot of space. Therefore, many companies have begun to try to shape phosphorous powder to smelt yellow phosphorus, which can also replace part of the phosphate rock. According to the requirements of customers in the phosphate rock market, Jianjie Group has developed a phosphorous powder binder suitable for phosphorous powder molding. This product has good molding effects, less additives, and low production costs.Read more -
Recycling of Dedusting Ash from Steel Plant
Dedusting ash generally refers to the dust, smoke, sludge and other wastes left by the dedusting of steel plant. For example, during the blast furnace and converter smelting process, there are blast furnace bag ash, ash collected by LT dedusting method, steelmaking dedusting ash, etc. Dedusting ash is rich in Fe, CaO, MgO, C, etc., and some also contain elements such as Zn, K, Na, etc., which has high recycling value, and direct disposal will easily cause resource waste and environmental pollution. At present, dust from steel plant is returned to the furnace for recycling, and cold-pressed pellets are often used for recycling. Zn-rich ash contains a lot of environmental pollutants, which will not only cover a large area and cause environmental pollution problems, but also directly return to sinter production will also cause a decline in the quality of sinter, affecting the smooth running of the blast furnace and the life of the blast furnace. Therefore, in order to make reasonable useRead more -
Development Trend of Iron Ore Pellets Binder
As the demand for sustainable mining practices increases, the development of eco-friendly binding agents for ore pellets has become a major focus for mining companies. The use of traditional binding agents such as bentonite, a type of clay, has been proven to be unsustainable and harmful to the environment. Therefore, there is a need for more sustainable alternatives.One of the most promising developments in this field is the use of biopolymers as binding agents. Biopolymers are natural, renewable materials that are biodegradable and environmentally friendly. They can be derived from a variety of sources such as plant fibers, starches, and proteins.Another potential development is the use of nanotechnology in the production of binding agents. Nanoparticles can improve the strength and durability of pellets, reducing the need for excessive use of binders. Additionally, they can enhance the flow properties of the pellets, improving the efficiency of the production process.The developmentRead more
