I. Overview of the refractory industry
1.Definition of refractories
Refractory materials generally refer to inorganic non-metallic materials with a fire resistance above 1580 ° C. The price of magnesium carbon brick includes natural ore (refractory raw materials) and various products made according to certain purposes and requirements according to certain technological processes (refractory Products), has certain high temperature mechanical properties and good volume stability. Refractory materials are important basic materials involving high-temperature industries such as steel, nonferrous metals, petrochemicals, building materials, machinery, electricity, environmental protection and even national defense. The technological progress of refractories plays an irreplaceable key role in the development of high-temperature industries.
2.Types of refractory materials
Due to the wide variety of refractory materials and their wide range of uses, they have various classification methods. According to the application, it can be divided into refractory materials for blast furnace, open hearth furnace, converter, continuous casting, glass kiln and cement kiln.
According to the molding process, it can be divided into natural rock cutting saws, mud pouring, plastic molding, semi-dry molding and vibration, ramming, melt casting and other products.
According to the shape of refractory products, it can be divided into shaped products, refractory mud, and unshaped refractory materials. According to the firing method, it can be divided into fired products, non-fired products, and fused cast products.
According to chemical characteristics, it can be divided into three types: acidic, alkaline and neutral. Among them, the acidity is mainly refractory with silicon dioxide as the main component. The basic ones are mostly magnesium and calcium oxides. The neutral ones are three. Aluminum oxide, chromium trioxide, etc. can be divided into silicon products, aluminum silicate products, magnesium products, and carbon products according to chemical minerals.
According to the degree of fire resistance, it can be divided into ordinary refractory materials with a refractory temperature between 1580 and 1770 ° C, advanced refractory materials with a refractory temperature between 1770 and 2000 ° C, special grade refractories with a refractory temperature above 2000 ° C, and a refractory temperature at 3000 ° C Above four categories of super refractory materials.

3.Technical environment of refractory industry
The technological progress of the high temperature industry itself and the requirements for energy saving and consumption reduction have promoted the technological progress and industrial upgrade of the refractory industry. The development of the high-temperature industry requires that the consumption of refractory materials per unit product be reduced, and the requirements for the quality and performance of refractory products continue to increase. Therefore, the demand for traditional refractory materials will gradually decrease, but at the same time, it will provide new refractory materials with high technological content and high added value. It has broader market space and profit prospects, which is conducive to product upgrades, structural adjustments and efficiency improvements in the refractory industry.
Development status of the world's refractory industry
At present, the global refractory output is about 40 million tons. China's refractory output accounts for about 64% of the global total refractory. Other production is mainly concentrated in countries and regions such as the European Union, the United States, Japan, and South Korea. Source: Public data collation
The United States is a larger exporter and importer of refractories. Import low-cost products and export high value-added products. Quantitatively, the United States is a net importer of refractories, although the net imports are small. In recent years, the United States has developed porous high-performance materials with thermal insulation function, resistance to metal melts, and excellent chemical erosion, which has promoted the development of functionalization and reduction of refractory materials.
Japan and other countries have also developed high-performance alumina, zirconia fibers and their products that can be used at temperatures above 1500 ° C for a long time, and environmentally-friendly and ecologically degradable fibers with an application temperature above 1260 ° C.

3. The main problems in the refractory industry
1. Serious overcapacity and chaotic market order
The refractory industry is one of the earliest industries to enter the market. Due to the low entry barriers, the amount of investment can be large or small, and the production process of some products is simple, so the production capacity is relatively fast, especially in the 1980s and 1990s. The refractory industries in Henan, Shandong, Shanxi and other provinces with resource advantages have developed rapidly, and the refractory industries in coastal provinces such as Jiangsu and Zhejiang have also formed a certain scale.
However, the development of the refractories industry has gradually begun to show some signs of overcapacity, which is mainly manifested in structural excesses of varieties, mainly due to the oversupply of ordinary refractory products with low technological added value. In recent years, it has developed into a full overcapacity. That is to say, the high-end refractory products with high technological content and high added value are also in excess of demand, causing a serious surplus. Overcapacity will inevitably lead to disorderly competition among enterprises and chaotic market order. Downstream industries will continue to drive down purchase prices and unpaid defaults. Without a good operating environment, the company has been operating at a margin.
2. Low industrial concentration
According to statistics from the National Bureau of Statistics, there are nearly 2,000 enterprises above the scale in the production of refractory raw materials and products, but there are only more than 100 refractory raw materials and products manufacturing enterprises with annual sales income of over 100 million yuan. In 2018, there were only 17 production companies whose main business income of refractory exceeded 1 billion yuan. The concentration of refractory industry has improved in recent years, especially during the "Twelfth Five-Year Plan" period, but the small, large and scattered status quo has not been completely changed.
3. The level of enterprise equipment is uneven, the level of automation is not high, labor productivity is low, product quality stability is poor, and technical resources are scattered. These aspects restrict the healthy and stable development of the industry to varying degrees.
