Nickel is a silver-white metal, in the air is easy to be oxidized by the air, the surface of the formation of some hair of the oxide film, so people often see the color of nickel hair.Nickel is hard, ductile, magnetic and corrosion resistant, and highly polished.Nickel is also abundant in the earth's crust.Nickel silicate ore or sulfur, arsenic, nickel compounds exist in nature.
The development of nickel
In recent years, the production and consumption of nickel in the world is relatively stable, the supply and demand of nickel in the world market mainly changes with the development of the stainless steel industry. With the increase of the application of nickel in the consumption of stainless steel industry, the smelting technology of ferronickel has made great progress, and the output of high-grade ferronickel has been greatly improved.Russia, Canada, new caledonia, Indonesia, Australia and Cuba account for about 80% of the world's nickel production and exports.
At present, China is the world's largest producer and consumer of nickel and iron. With the continuous development of economy and steel industry, the demand for nickel resources is increasing, but at the same time, the output of nickel ore is also increasing, which gradually leads to the severe pattern of global nickel market oversupply.In domestic stainless steel production, the proportion of nickel and iron used as raw materials will increase year by year, and the use of pure nickel will decline.And with the constant development of China's nickel industry at the same time, the question comes, such as nickel more for low grade, proportion of open-pit mining is very small, less recoverable reserves, mining and smelting technology is relatively backward, and also has the very big disparity with the world advanced technology, mining and smelting cost is high, thus, China's nickel industry still has great space for development.
USES of nickel metal
Nickel has good plasticity, corrosion resistance and magnetic properties, so it is mainly used in steel, nickel-based alloy, electroplating and battery fields, widely used in aircraft, radar and other military manufacturing, civil machinery manufacturing and electroplating industry.
Iron and steel sector
Nickel has good corrosion resistance, high temperature resistance, rust resistance and other properties, so it is widely used in stainless steel and alloy steel field.
The largest consumption of nickel is in stainless steel applications, with two-thirds of the world's primary nickel ore used in the production of stainless steel.Stainless steel containing nickel can resist the corrosion of atmosphere, steam and water, and can resist the corrosion of acid, alkali and salt, so it is widely used in the chemical industry, metallurgy, construction and other industries, such as the production of petrochemical, textile, light industry, nuclear energy and other industries that require welding vessels, towers, tanks, pipelines, etc.Production of urea production in the synthesis tower, washing tower, condensation tower, stripper tower and other corrosion - resistant high-pressure equipment.According to the proportion of nickel, nickel containing stainless steel is mainly divided into: austenitic stainless steel, austenitic - ferrite dual phase stainless steel, precipitation hardened stainless steel.
Nickel base alloy field
Nickel-based alloys are alloys with high strength and corrosion resistance at 650 ~ 1000℃.According to the main properties can be subdivided into nickel-based heat resistant alloy, nickel-based corrosion resistant alloy, nickel-based wear resistant alloy, nickel-based precision alloy and nickel-based shape memory alloy.Nickel base alloy products mainly include: electric stove, electric iron, turbine engine turbine disc, combustion chamber and turbine blades, color TV, communications equipment, the pendulum clock and measuring tape, manufacturing furniture, have the fine tools, the performance of permanent magnet used on spacecraft automatic open structure, since the motivation of aerospace industrial fasteners and biomedical use artificial heart motor, etc.Widely used in aviation, shipping, chemical, electronics, medicine and energy industries.
Nickel plating refers to a layer of steel and other metal substrate covered with a layer of durable, corrosion resistant coating, corrosion resistance than galvanized high 20% ~ 25%.Nickel - plated articles beautiful, clean, and not easy to rust.The processing quantity of electroplating nickel is second only to electroplating, and its consumption accounts for about 10% of the total nickel production.Nickel plating is divided into electroplating nickel and electroless nickel plating.
Gold-plated nickel is also used in the field of batteries, mainly nickel-hydrogen batteries, cadmium-nickel batteries and nickel-manganese batteries.In recent years, the most rapid development is the application of increasingly practical mhx-ni battery, its advantages are non-toxic green pollution-free, battery storage than nickel-cadmium battery more than 30%, lighter than nickel-cadmium battery, longer service life, the disadvantage is more expensive than nickel-cadmium battery, performance is worse than lithium battery.Mainly used in mobile communications, notebook, video recorder and other fields also used in military, national defense, high-tech and other fields.
Anyang daguan metal co., ltd. was established in 2006, specializing in the production of metallurgical accessories.After more than 10 years of efforts and development, has become a domestic rapid development, larger, stable quality, trusted by customers of the benchmark ferroalloy industry enterprises.
In 2012, our company obtained export license.The company has 10 sets of intermediate frequency furnace and 4 core wire production lines, with an annual output of more than 20,000 tons of auxiliary materials for steelmaking and casting.Mainly includes the ferroalloy (ferrosilicon, calcium silicon, silicon barium, calcium silicon, silicon barium aluminum, high silicon aluminum barium calcium, calcium silicon manganese, silicon, silicon carbide and carbon recarburizer), nodulizing agent (rare earth silicon magnesium alloy), nucleating agent (silicone, barium, calcium, zirconium, etc.), deoxidizer (aluminum and calcium), alloy ball (silicon, silicon, silicon carbide ball), alloy slag slag (ferrosilicon, silicon slag, rich manganese slag) and packet core.With excellent production equipment, strong technical force, advanced production technology and unique formula, the product ingredient content can be produced in strict accordance with customer requirements, in use with high efficiency, stable reaction, absorption and fusion of good characteristics.
At present, 40% of the products are used in large domestic steel mills and founders, including Shagang group, Rizhao iron and steel group, Shougang group, Wuhan iron and steel group, etc.60% of the products are exported to more than 30 countries and regions such as South Korea, Japan, Russia, Ukraine, Turkey, Germany, India, Australia and Iran, including posco iron & steel group, Hyundai iron & steel group and JFE iron & steel group.With stable quality and high quality technical services, our products have won the praise and trust of customers at home and abroad.
In the future, the competition will be more intense, Henan guorui will continue to strictly comply with the requirements of iso9001:2008 quality management system, continue to focus on customer needs, committed to providing newer, better quality products and more satisfactory services for steelmaking and casting industry. Henan guorui sincerely hope to join hands with more enterprises to advance together and create brilliant.
