The following is an introduction to these concept stocks:
1, ruitai Science and Technology
The company is the birthplace of new products and processes for melting and casting refractories in China, ranking second in terms of production capacity and market share. The main products are divided into two series: fused cast zirconia corundum and fused cast alumina, with annual production capacity of 7000 tons and 600 tons respectively.
2. leijin stocks
Leijin Co., Ltd. is one of the leading magnesia-calcium refractories enterprises, and its market share in 2008-20 10 was 10.39%, 12.64% and 14.82% respectively, increasing year by year. The company is close to the upstream resource storage area, which helps to reduce production costs and further industry integration. Technically, the company not only has the leading domestic "ultra-high purity magnesia-calcium brick technology", "unburned magnesia-calcium brick technology" and "high calcium magnesia-calcium brick technology", but also has key technologies such as magnesia-calcium synthetic sand production technology and magnesia-calcium brick waterproof technology. Compared with magnesia-calcia brick, the graphite consumption of the newly developed magnesia-calcia brick is reduced by 50%, and the cost advantage is obvious.
3. Pune shares
The company has become the main manufacturer of functional refractories and unshaped refractories in China, and has the largest market share of steel out-of-furnace refined permeable bricks and the largest supplier of refractories for steel industry in China. The company's annual output is 6.5438+0.2 million tons of breathable bricks, 6.5438+0 million tons of bulk materials, 25,000 tons of prefabricated parts (seat bricks, slag baffles, electric furnace tops, etc.), 3,000 tons of heat storage balls, 500 cubic meters of heat storage bodies and other products; Punai Functional Company has a production line with an annual output of 3,000 tons of continuous casting, 1 1,000 tons of sliding plate nozzle and 2,400 tons of silicon nitride combined with silicon carbide. Yingkou Punai Company has a production line with an annual output of 50,000 tons of magnesia-carbon bricks and 654.38+10,000 tons of magnesia bulk materials. The product range is complete, and the production capacity ranks in the forefront of the industry. More than 20 series and 200 varieties of refractories produced by the company are widely used in steel, non-ferrous metals, electric power and other fields.
4. Beijing Lier
The company is one of the largest comprehensive contracting suppliers of refractory materials in the iron and steel industry in China, integrating material design, research and development, configuration, manufacturing, supporting, installation, construction and maintenance. It is also one of the largest manufacturers and suppliers of refractories in China. By the end of 2009, the company had a production capacity of nearly 14 10000 tons of refractory products. The unshaped refractories produced by the company, such as tundish lump-sum materials, castable for permanent lining and cover, series refractories for annular heating furnace and refractories for direct reduction iron, have the first market share in China, and the second market share of permeable bricks in China.
5. Jinyu shares
The company is the largest unshaped refractory supplier in China and one of the largest unshaped refractory design, research and development, manufacturing and service providers in China. Mainly through the subsidiary Beijing Tongda Refractory Technology Co., Ltd. to manage the refractory business, in June 2009, Beijing Tongda was awarded the national enterprise technology center. China is rich in refractory raw materials, and bauxite, magnesite and graphite, which are the basic raw materials of refractory materials, are abundant. The proven basic reserves of bauxite exceed 2 billion tons, making it one of the three largest bauxite exporters in the world. The proven basic reserves of magnesite are 3.4 billion tons, ranking first in the world. With proven basic reserves of 800 million tons, graphite is a big exporter of graphite.
6. Oriental Zirconium Industry
The company is engaged in the research, development, production and sales of zirconium series products. The main products are "Yutian" brand zirconium oxychloride, zirconium dioxide, composite zirconia, zirconia structural ceramics, zirconium silicate and other five series of zirconium products with more than 80 varieties and specifications. It is one of the most complete professional manufacturers of zirconium products in the world. Zirconium series products are mainly used in nuclear power sources, special ceramics, optical communication devices, solid fuel cells, weapons and aerospace fields, ceramic glaze and ceramics.
7. Luyang shares
Inner Mongolia Luyang Energy-saving Materials Co., Ltd., a wholly-owned subsidiary, plans to invest 4.39 billion yuan to build a circular economy industrial park of coal gangue deep processing industry chain and related projects, which will be completed by stages in four years. Make full use of the abundant raw materials, energy and other resources in Inner Mongolia, speed up the comprehensive utilization of coal gangue, speed up the development and popularization of building insulation, refractory raw material application and other fields, seek new profit growth points, improve profitability and broaden development space.
8. Haiyuan machinery
Friction press is mainly used in China's refractory industry, with backward technology, serious pollution and low safety performance in production process. Advanced, efficient and environmentally friendly equipment represented by HC press needs to be upgraded urgently. The company is the only enterprise in China that has entered the refractory full-automatic hydraulic brick press industry. Prior to this, only two leading international enterprises, German Rice Company and Italian Sacmi Group, had a small amount of sales in China, and the market promotion was slow due to the cost performance.
