Metallurgy in the main points of the treatment operation
Metallurgy in the main points of the treatment operation What are the key points of the gestation processing operation:First, the selection of the inoculant is uniform in size and moderate in size, so as not to affect the incubation effect, and the molten iron after conception should be fully stirred before slag treatment;Second, it is necessary to strictly control the time of incubation treatment, especially the use of Si-Fe inoculating agent, the anti-recession performance is not good, and the incubation time must be controlled at more than 70% of the iron production time; (Long-acting incubation using barium silicon inoculant)Third, to determine a breeding amount, for gray iron parts, generally controlled at 0.3%-0.6%, do not blindly increase the amount of pregnancy, too high the amount of gestation will increase the viscosity of the iron and slag inclusion, shrinkage, shrinkage tendency.The operation process of gestation treatment is a very important process, and attention should be paid to various details, otherwise the desired gestation effect will not be achieved. Generally speaking, the effect of following the flow is good, so when conditions permit, use the flow of pregnancy. When incubating in front of the furnace, artificial incubation is generally carried out in the molten iron outlet tank, which can achieve better incubation results. There are also spontaneous incubations under automatic control conditions, and its advantage is that the control of the amount of pregnancy is more accurate.If you need it, you can contact us!Email: joanna@aykxgj.com +8616638320060

How to choose graphite powder
How to choose graphite powder The higher the finish of graphite powder with small particle size: for example, graphite powder can be used as a negative electrode material for batteries, and the size of graphite powder particle size directly plays an important role in the finish of the entire production process, because the smaller the particle size, the higher the finish of the processed product. So is it better to choose the smaller the particle size of the graphite powder? Of course not, after the particle size of graphite powder is small, the flexural strength of the product will decrease, and even the phenomenon of breaking will occur at high temperature. Therefore, we will find that large-sized graphite electrodes will not be produced with small particles of graphite;The size of the particle size will affect the expansion of the flake graphite powder: the expansion factor of graphite is proportional to the particle size of the graphite. Expanded graphite has a rich pore structure, the smaller the particle size of graphite, the network pore structure of expanded graphite will also decrease, the lower the expansion coefficient, and vice versa, the larger it will be. Therefore, in the fields of sealing, fireproof coatings, etc., graphite with large particle size should be selected as a material. Now, the particle size of graphite materials is developing in a subtle direction, but not the smaller the particle size, the better the performance of graphite, find the right graphite for their own industry, and have a higher cost-effective application is the key problem.You can contact me if you need toEmail: joanna@aykxgj.com +8616638320060

What are the applications of ferrosilicon nitride in artillery mud
What are the applications of ferrosilicon nitride in artillery mud:1. Compared with the addition of silicon carbide or silicon nitride to the cannon mud, the high-temperature flexural strength at many temperatures has been improved to varying degrees, and ferrosilicon nitride can be decomposed to produce nitrogen at high temperature, and dispersive tiny pores are produced in the cannon mud, which is conducive to improving the drilling rate of the cannon mud;2. The key to the application of ferrosilicon nitride different from silicon carbide and silicon nitride in artillery mud is that there are ductile particles in ferrosilicon nitride to enhance iron and intermetallic compound iron silicide, which promotes the sintering of artillery mud and improves the bonding strength between oxide and non-oxide;3. In the clay, with the increase of ferrosilicon nitride addition, the flexural strength increases correspondingly in the temperature segment; When ferrosilicon nitride is added more than a certain amount, the porosity of the mortar increases significantly, and the flexural strength of each temperature section decreases accordingly.4. There is almost no difference in the resistance of slag and iron erosion of the cannon mud with silicon carbide, silicon nitride and ferrosilicon nitride respectively. The addition of ferrosilicon nitride has little effect on the slag resistance and iron erosion resistance of the gun sludge.The above are some suggestions, I hope it will be helpful to everyone!You can contact me if you need toEmail: joanna@aykxgj.com +8616638320060

What are the characteristics of silicon-carbon alloys Silicon-carbon alloy is a new type of metallurgical material, but it is much cheaper in price than other metallurgical materials, in addition, silicon-carbon alloy can replace ferrosilicon, silicon carbide and other metallurgical materials. What are the characteristics of silicon-carbon alloys:1. Silicon-carbon alloy has a strong deoxidation effect, because silicon-carbon alloy contains silicon elements, after adding silicon-carbon alloy in the steelmaking process, the silicon element in it reacts with oxygen to deoxidize the molten steel to improve the hardness and quality of the steel, and the silicon element in the silicon-carbon alloy has a good affinity with oxygen, so the molten steel also has the characteristics of non-splashing after being put in;2.

Effect of ferrosilicon
Effect of ferrosilicon:1. Used as a deoxidizer and alloying agent in the steelmaking industry: in order to obtain the quality of steel and steel with qualified chemical composition, deoxidation must be carried out in the later stage of steelmaking, and the chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for precipitation and diffusion deoxidation in steelmaking. Adding a certain amount of silicon to steel can improve the strength, hardness and elasticity of steel, so ferrosilicon is also used as an alloying agent when smelting structural steel (containing silicon 0.40-1.75%), tool steel (containing SiO.30-1.8%), spring steel (containing SiO.40-2.8%) and silicon steel for transformers (containing silicon 2.81-4.8%). At the same time, the inclusion form reduces the gas element content in the molten steel, which is an effective new technology to improve the quality of steel, reduce costs and save iron. Suitable for continuous casting steel water deoxidation requirements, practice has proved that ferrosilicon not only meets the requirements of steelmaking deoxidation, but also has desulfurization performance and has the characteristics of large proportion and strong penetration;2. Used as inoculant and nodularizer in the cast iron industry: cast iron is an important metal material in modern industry, it is cheaper than steel, easy to melt and smelt, has good casting performance and much better seismic resistance than steel. Ductile iron, whose mechanical properties reach or are close to the mechanical properties of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron, promote the precipitation and spheroidization of graphite, so in the production of ductile iron, ferrosilicon is an important inoculant (to help precipitate graphite) and nodularizer;3. Used as a reducing agent in the production of ferroalloys: not only the chemical affinity between silicon and oxygen is very large, but also the carbon content of high ferrosilicon is very low. Therefore, high ferrosilicon (or siliceous alloy) is a reducing agent commonly used in the production of low-carbon ferroalloys in the ferroalloy industry;4. Other uses: finely ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as a coating for welding rods in the electrode manufacturing industry. High ferrosilicon can be used in the chemical industry to manufacture products such as silicone.The company sells ferrosilicon, there are 72#, 75# and so on, you can contact if you need!You can contact me if you need toEmail: joanna@aykxgj.com +8616638320060
