Type of refractoryTime of issue : 2013- 04-11
There are many kinds of refractory materials, usually divided into ordinary refractory materials (1580～1770°C), advanced refractory materials (1770～2000°C) and special refractory materials (above 2000°C) according to the degree of refractoriness; Neutral refractory and alkaline refractory. In addition, there are refractory materials for special occasions.
Now the definition of refractory material has not only depended on whether the refractoriness is above 1580 °C. At present, refractory materials generally refer to inorganic non-metallic materials used in the lining of production equipment such as metallurgy, petrochemical, cement, ceramics, etc.

How to choose a reasonable firing processTime of issue : 2013- 10-10
How to choose a reasonable firing process is the way to save energy and reduce consumption
There are various sintering processes in the production of sintered bricks in the kiln. When the sintering process is selected, it is also one of the advantageous ways to save energy and reduce consumption. For example, in the one-time burning process, the internal combustion bricks are used. When determining the code burning process, according to the different raw materials, combined with the structural characteristics of the kiln, there is much to do in the blending of internal combustion. For example, we use a modern advanced kiln to burn certain raw materials and specific products, and 300Kcal of heat per kilogram of product can complete the sintering process. Another kiln type used in another sintering process, firing 400-500Kcal per kilogram of product, can complete the sintering process, so the difference between each kilogram of product is between 100 and 200Kcal, we average 150Kcal calories, one year. The brick factory with 60 million pieces of production saves 4,500 tons of standard coal every year. According to the calculation of 450 yuan per ton, it can save more than 2 million yuan in fuel costs every year. In terms of internal combustion blending, we must do a uniform amount of mixing, one can not be more miserable, and the second can not be less. Excessive amounts are prone to excessive sintering temperatures and waste of pyrogens. Less mixed kiln temperature does not come, easy to produce raw bricks, temperature is not enough, product quality is low, then we have mastered the internal combustion blending to be finely processed to ensure the uniform mixing of raw materials, in order to achieve the desired effect.
"Twelfth Five-Year Plan" China's refractory industry opportunities and challenges coexistTime of issue : 2014- 04-18
The "Twelfth Five-Year Plan" is a crucial period for China to build a well-off society in an all-round way. It is a period of deepening reform and opening up and accelerating the transformation of economic development. The development of China's refractory industry faces both rare historical opportunities and many risks and risks. challenge.
The international situation: From the global situation, the international environment is generally beneficial to China's industrial development. However, compared with the past decade, the international environment for China's industrial development will gradually tighten. The first is that the global economy may enter a period of low growth. In the post-financial crisis, the world economy will be growing at a low rate for a certain period of time. Secondly, the global supply and demand structure will undergo significant changes. Now some major economies are planning to make deep adjustments in the economic structure, seeking re-industrialization with advanced manufacturing as the core, and hope to revitalize the manufacturing industry and expand exports. Emerging economies and developing countries are also accelerating the development of industries and technologies with their own comparative advantages. China's traditional advantageous industries will face more intense international competition. Once again, the international trade environment is not optimistic. The financial crisis has intensified trade protection. The color of trade protectionism has become increasingly strong, trade friction has increased significantly, the world trade environment has become increasingly complex, and the total volume of international trade will show a downward trend.

Domestic situation: With the implementation of the country's proactive fiscal policy and prudent monetary policy, the risks and challenges faced by China's refractory industry are also obvious. First, the ultra-conventional fixed asset investment, which is based on large-scale infrastructure construction, has been transferred to the downstream deceleration channel, and the domestic economic growth rate will be reduced. The overall growth rate of fixed asset investment has fallen sharply, and the demand for steel, cement, glass and other industries will decline, which inevitably will affect the market of refractory materials. Second, the monetary policy has changed from moderately accommodative to stable, the prices of raw materials may continue to rise, the cost of production factors in the real economy will gradually increase, and the profit margin of production and operation of the industry will be squeezed. Third, the constraints on resources and environment will be further tightened. With the government's efforts to strengthen resources, energy and environmental management, the constraints on the production of refractory industry are becoming more and more obvious. The task of energy conservation and consumption reduction in the whole industry, pollution control and emission reduction is very arduous. The tight situation of some refractory raw materials is also difficult to alleviate in the short term.
Industry situation: From the perspective of China's refractory industry itself, although the progress has been made in recent years, the current situation of the whole industry still has many unsuitable places compared with the development of various industries in the national economy, especially the high-temperature industry. There is also a certain gap. In addition to the aforementioned problems, the industry is generally over-capacity, low industrial concentration, and low resource utilization. We should especially recognize that as a global refractory production and consumption country, despite the large capacity of refractory products, There are few high-tech varieties, and the proportion of “green new” refractory products is low; in the face of international markets with high potential, there are not many high-grade, high-tech, high value-added products; high proportion of common products, amorphous The proportion of refractory products is low. In addition, the overall level of technological innovation and clean production in China's refractory industry is also lower than the international advanced level.
The main tasks of the future: China's refractory industry during the "Twelfth Five-Year Plan" period, opportunities and challenges coexist. We must recognize the situation, strengthen our confidence, and firmly establish a global consciousness, an international vision and a strategic thinking. Under the guidance of the scientific concept of development, we should accelerate the transformation of development mode as the main line, study new ideas, formulate new measures, create new situations, and earnestly Live and use important strategic opportunities, and build on the sustainable development of the industry on the basis of structural upgrading, product optimization, energy co
