The earthquake in Japan may lead to a decline in Japan's iron and steel output value, which is conducive to the decline in China's iron and steel exports and iron ore prices, and the demand for refractory information.
Refractory materials refer to inorganic non-metallic materials whose refractoriness is not less than 1580 C. They are all necessary basic materials for high temperature industrial kilns such as metallurgy, building materials and chemical industry. There are many kinds of refractory materials. According to their appearance, refractory materials can be divided into refractory bricks (products with certain shapes) and unshaped refractory materials (abbreviated as bulk materials). In the meantime, refractory bricks can be divided into sintered bricks, non-sintered bricks, fused bricks (fused cast bricks) and refractory insulation bricks. The refractory materials for melting and casting are divided into two series: zirconium corundum and alumina. They are mainly used in float glass furnace, electronic glass furnace, daily glass furnace, and industrial furnaces such as glass fiber, special glass, some ordinary flat-pull and Griffith glass furnaces. The heating guideways and steel outlets of metallurgical enterprises are also rarely used. The refractory material for melting and casting is the key building material directly touching the liquid glass in glass melting furnace. Its quality directly affects the quality of glass and the technological progress of glass melting furnace. In the structural adjustment of glass industry in China, the refractory material for melting and casting plays an extremely important role.
The professional competition of refractory materials is fierce, and the surplus is affected by the original data, so it is inevitable to extend upward. Iron and steel are the primary downstream refractories. By the end of 10 years, the number of refractory materials enterprises was 254, with 9% added, and the rate of adding them dropped dramatically. In 2006-09, the number of refractory materials enterprises increased steadily, with an increase of 20% in 2009. Refractory materials are mainly downstream of steel, accounting for about 60%, followed by heavy industries such as building materials, chemical industry and non-ferrous industries. Historical data show that the output growth rate of refractory data is highly correlated with that of crude steel. Following the maturity of the refractory material career cycle and the changes brought about by the integration of the obscene profession, especially the iron and steel profession, the refractory material profession is experiencing an innovation.
The profession of refractory materials will usher in the integration period of annexation and reorganization. The driving force of the profession integration comes mainly from the promotion of the profession structure, which is manifested as follows:
1. Career development form promotion: Career development form is transiting from the growth stage to the industrial promotion stage, from the rude addition of purely seeking output value to the progressive product level and seeking the change of added value.
2. Promotion of product function: Fire-proof material products transit from single-sought fire-proof nature to multi-function, energy-saving and environmental protection.
3. Promotion of enterprise surplus form: In the past two decades, the refractory profession has shared the rapid addition of downstream professions such as iron and steel. In 2007, the output value of refractory materials in China has reached 29.11 million tons, accounting for half of the total output value of international refractory materials, and the compound addition rate has reached more than 30% in the past six years. However, with the slowdown of the growth rate of the output value of downstream professions such as iron and steel profession, the demand for refractory materials has increased. Growth began to slow down, while output growth stagnated in the past two years.
Future careers will end in the form of added output value, which is motivated by industrial promotion. Energy saving and consumption reduction have an impact on the product structure of refractory materials from two aspects. On the one hand, the refractory material itself is a high energy-consuming profession, along with the advancement of skills, the service life of refractory material is constantly increasing, and the amount of steel-making per ton of refractory material is added, which saves the use of refractory material. On the other hand, energy saving and consumption reduction in iron and steel exercise can not be separated from technological innovation and skill innovation, which necessarily requires the function of refractory materials to advance. The progress of the refractory data profession entering the threshold, the fast integration of the downstream customers and the gradual improvement of the skill standards will force the refractory data manufacturers to improve their own skill standards. Small firms with no advantage in skills will find that the environment is increasingly unable to make a living for them, and the advantage of skills and funds will enable leading enterprises to obtain the opportunity to expand their market share.
