The role of molybdenum in steel can be summarized as improving hardenability, improving thermal strength, preventing temper brittleness, improving remanence and coercivity, and corrosion resistance in certain media, and preventing pitting corrosion. Due to the various beneficial effects of molybdenum in steel,it has been widely used in a series of steel grades such as structural steel, spring steel, bearing steel, tool steel, stainless acid-resistant steel, heat-resistant steel (also known as heat-strength steel), and magnetic steel. Molybdenum is very effective in improving strength and toughness in cast iron. When the addition amount is 0.25% to 1.25%, it can also form pearlite matrix structure for castings with medium and large sections. Commonly used in rolls and other wear-resistant castings.
Among these uses, the steelmaking, foundry and ferroalloy industries are users of ferrosilicon. Together they consume about 90% of the ferrosilicon. Among various grades of ferrosilicon, 75% ferrosilicon is widely used at present. In the steelmaking industry, 3-5 kg of 75% ferrosilicon is consumed per ton of steel produced.
Silicon manganese alloy is used for steelmaking. The melting points of the deoxidized products MnSiO₃ and Mn₂SiO₄ are 1270°C and 1327°C respectively. They have the advantages of low melting point, large particle size, easy floating, and good deoxidation effect.
Specifications and particle size: natural block, 10-100mm, powder or customized according to customer requirements.
Packaging: one metric ton in a large bag, or according to customer requirements
Steel industry: Ferromanganese is an indispensable deoxidizer and desulfurizer in the steelmaking industry. Good steel needs to be deoxidized and desulfurized during smelting, and the use of deoxidizers will greatly increase its cost. Therefore, ferromanganese is a cheap deoxidizer. Desulfurization refers to the removal of harmful substances such as sulfur in steel. ferromanganese can well achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel, and improve the quality of steel.
Green silicon carbide is made from petroleum coke and high-quality silica as the main raw materials, with salt as an additive, and is smelted at high temperature in a resistance furnace. The smelted crystal has high purity and high hardness. Its hardness is between corundum and diamond, and its mechanical strength is Higher than corundum.
Compared with black silicon carbide, green silicon carbide has advantages in high temperature, electrical insulation and chemical stability.
The high-purity magnesium ingot provided by Zhen’an Metallurgy refers to the bulk metal material smelted from pure magnesium or magnesium alloy, which is an important light metal material.
Magnesium ingot usually in the form of strips or cubes, the size and weight can be customized according to customer needs.Magnesium ingots can be made to varying levels of purity depending on the intended use. The most Common grade of magnesium ingot is 99.9% pure, which is often used for alloying with other metals.
Nickel Niobium 60% finds its main application in the production of nickel based superalloys and special nickel steels.
Niobium is used as an additive in nickel-, iron- or cobalt-based superalloys. It not only has a high melting point of 2477°C, but is also resistant to corrosion and oxidation.
Due to its high melting point and excellent oxidation and corrosion resistance, nickel niobium is a preferred component in superalloys used for parts that must withstand high temperatures.
Graphitized petroleum coke is a high-purity carbon material produced at a temperature of 2500-3500°C. It has the characteristics of high fixed carbon content, low sulfur, low ash and low porosity. It is black in color, porous, in the form of accumulated granules, and cannot be melted.
Calcined petroleum coke (CPC) is the byproduct obtained from the coker unit in a crude oil refinery. lt is primarilyused to make anodes for the aluminum, steel, and titanium smelting industry.
Petroleum coke manufactured by delayed coking of residues obtained from crude oil distillation units of oil refineries is called green or raw petroleum coke. The said green or raw petroleum coke calcined at a temperature 12000 centigrade to 13000 centigrade is known as calcined petroleum coke.
Black silicon carbide is a non-metallic ceramic material composed of carbon and silicon elements. Black silicon carbide has very high hardness, belonging to Mohs hardness level 9.5, second only to diamond and cubic boron nitride.
Electrolytic manganese flakes are pure metal element manganese, with a content of 99.7%-99.9%. It is mainly used as an additive in steel manufacturing.
Electrolytic manganese has high purity and is often used to increase the hardness of alloys. It is widely used in materials such as manganese-copper alloy, manganese-aluminum alloy, and 200 series stainless steel to improve their strength, toughness, wear resistance, corrosion resistance, etc.
Electrolytic manganese flakes are pure metal element manganese, with a content of 99.7%-99.9%. It is mainly used as an additive in steel manufacturing.
Choosing to purchase our electrolytic manganese flakes has advantages in many aspects. First of all, the electrolytic manganese flakes we provide, with their high purity (99.8%) and high-quality materials, significantly improve the alloy strength, helping customers reduce the use of materials while reducing overall production costs.
