In 2020, the net profit was 65.438+69.8 million, a year-on-year increase of -33.33%. Hegang Co., Ltd. is a super-large iron and steel enterprise formed by the merger of Tangshan Iron and Steel Co., Ltd., Handan Iron and Steel Co., Ltd. and Chengde Vanadium and Titanium Co., Ltd. through the stock market.
Second, Longbai Group
The net profit in 2020 was 2.289 billion, up-1 1.77% year-on-year. The company has titanium resources in Panzhihua and Yunnan, and a small amount of zircon resources in Australia through its subsidiary Oriental Zirconium Industry.
Three. Anning stock
The company's net profit in 2020 was 7.065438 billion yuan, a year-on-year increase of 34.93%. The company is a leading titanium enterprise in China, mainly engaged in the mining and sales of vanadium-titanium magnetite. The main products are titanium concentrate and vanadium-titanium iron concentrate. After more than 20 years of development, the company's titanium metal recovery rate is in the leading position in the industry, and the domestic output of titanium concentrate ranks first in the market.
Characteristics of raw materials:
Titanium is a typical pro-MagmaElemental, usually in the form of oxide minerals. There are more than 80 kinds of minerals with TiO2 _ 2 content above 1% in the crust, among which 15 kinds are of industrial value. In China, ilmenite, rutile and titanomagnetite are mainly used (Table 3.5. 1). They are both primary minerals (rock minerals) and secondary minerals (weathered eluvial deposits and sedimentary placers).
Characteristics of titanium:
Because metallic titanium is silvery white, it has the characteristics of high melting point (1727℃), light specific gravity (4.5), high mechanical strength (5), low temperature resistance (the resistivity is almost zero at ultra-low temperature), wear resistance, good plasticity (thin wall), difficult oxidation, strong reduction and so on. Titanium dioxide is an oxide of titanium, which is non-toxic, has good physical and chemical stability (1000℃ and is insoluble in any acid or alkali), high refractive index (2.55 ~ 2.70) and strong whiteness and coloring (150 ~ 65438).
Therefore, titanium and its oxides and alloys are important coatings, new structural materials and anticorrosion materials. They are called "the third developing metal after iron and aluminum" and "strategic metals", and they are also "promising metal materials", which are used in aviation, aerospace, shipbuilding, military industry, metallurgy, chemical industry, machinery, electric power, seawater desalination, transportation, light industry, environmental protection and other fields.
