The refractory industry will face three pressures: first, the operating pressure of oversupply and disorderly competition in the market caused by overcapacity, and the long-term decline in the price and operating quality of refractory products will be difficult to change in the short term; Second, the pressure of high financial cost and insufficient liquidity caused by insufficient self-owned funds of enterprises, difficult recovery of receivables and rising real interest rate of bank loans; Third, the environmental protection investment is in debt, and the environmental protection cost will increase day by day.

What industry does refractories belong to? What is the prospect of refractories industry?
Refractory is a kind of inorganic nonmetallic material with a fire resistance of not less than 1580 degrees. Refractory refers to the temperature in Celsius at which the cone-shaped sample of refractory can resist high temperature without softening and melting under the condition of no load. However, refractories can't be fully described only by the definition of refractoriness, and 1580 degrees is not absolute. Now it is defined that any material whose physical and chemical properties allow it to be used in high temperature environment is called refractory.

What is unshaped refractory? What are unshaped refractories?
Amorphous refractory is a kind of refractory material which is made of refractory aggregate with certain particle size gradation, powder, binder and admixture. They have no fixed shape and can be made into slurry, mud paste and loose, so they are also called loose refractories. Used for lining of thermal equipment, directly baked without sintering process. Compared with refractory bricks, unshaped refractory materials have the characteristics of simple process (due to the omission of firing process), energy saving, low cost and convenient mechanized construction. The application effect is better than that of refractory bricks in some thermal equipment.

Classification and application of refractory materials
Refractory materials are essential components in various industrial processes due to their ability to withstand high temperatures, thermal shock, and chemical corrosion. They are commonly used in industries such as steel, cement, glass, ceramics, and petrochemicals. Refractory materials can be classified based on their composition and application.
