At present, Liaoning Magnesium Oxide has been the largest producer and consumer in the world in China. The production of main building materials, such as cement, flat glass, building sanitary ceramics, stone and wall materials, has been the first in the world. At the same time, the quality of building materials is constantly improving, energy and raw materials consumption are declining year by year, a variety of new materials are constantly emerging, and building materials products are constantly upgrading and replacing. First, the output and benefit have been greatly improved. It is expected to produce 13.8 million tons of cement in 2007, 530 million weight boxes for flat glass, 110 million sanitary ceramics and 3 billion 500 million square meters for building ceramics. The total industry profit was 65 billion yuan, up 29%.
The two is to accelerate the pace of merger and reorganization of large enterprise groups. China Building Materials Group, China National Material Group and conch group speeded up the annexation and reorganization steps, and the cement production concentration degree increased significantly, which greatly improved the strength of China's building materials industry. Three, great progress has been made in the progress of science and technology. Nissan 10 thousand tons of new dry process cement production line, daily melting 900 tons float glass production line, daily melting 200 tons of ultra-thin glass production line, annual output of 120 thousand tons of glass fiber tank furnace drawing production line and other new technology and new equipment has achieved localization, and has reached the world's advanced level. Four, the structure of the product has been adjusted. The production line of the independent new dry cement technology and equipment construction has reached more than 800, and the proportion of the new dry cement has reached over 55%. The production line of float glass has reached 145. The proportion of float glass is 87%. New wall materials, new thermal insulation materials, new waterproof materials and decoration materials have been developed rapidly. The new inorganic nonmetal materials have made important contributions to the development of high-tech industries and the modernization of national defense, such as aviation, space, weapons, electronics, information and so on. Five is to eliminate backward cement production capacity. In the past few years, the large pressure, merger and reorganization, the elimination of backward, the high energy consumption of wet kiln, hollow kiln, a part of the backward cement small kiln have been eliminated. There are 206 original wet kiln production lines in the country, and the production capacity is 35 million tons. At present, in addition to the low cost areas in the western part of China, 5 million tons of wet kiln are still in production, and other areas have been basically eliminated. In 2007, 48 million 280 thousand tons of backward cement clinker were eliminated and 80 million tons of backward cement production capacity. The upgrading of the equipment level makes the energy consumption of the cement industry decrease significantly. In 2007, the comprehensive energy consumption of 138 kilograms of coal has been reduced by 4 kg of standard coal compared with the previous year. On 2008 the industry focus on the development of the national development and Reform Commission, Department of industry, building materials industry in 2008 will continue to implement the Scientific Outlook on Development, strengthen macro-control, in accordance with the construction of a conservation oriented society and the development of circular economy, encourage the development of advanced productive forces, accelerate the elimination of backward, efforts to adjust the structure, the construction of the building materials industry has become the international competitiveness of the important raw materials and industrial products and realize the transformation from large to strong. On the basis of the development of energy saving building materials and the establishment of circular economy, the upgrading of building materials will be accelerated so as to realize the conservation of resources and energy.
