Recently, the reporter learned from the county power group that the first phase of the 1.2 million-ton alumina project of Luoyang Xiangjiang Wanji Aluminum Co., Ltd., a key project of cities and counties, has progressed smoothly. At present, it has completed a total investment of 1.4 billion yuan, accounting for 66% of the total investment. . Luoyang Xiangjiang Wanji Aluminum Co., Ltd. has an annual production capacity of 1.2 million tons of alumina. It is a large-scale alumina company jointly invested by Xin'an Power Group and Xiangjiang Group. The total investment of the first phase of the project is 2.131 billion yuan. The project started construction in April 2005. The construction unit overcame various unfavorable factors such as capital and weather to ensure the smooth progress of the project. At present, the main body of the thermal power plant No. 3 of the project is 90% complete, the external power supply cable is over, the 110 kV line has already started construction, and the alumina plant finished product. The frame construction of garages, raw material mills, and gas plant main buildings was completed. The recycling pools and tar pits operation rooms had been completed. By the beginning of July, the project had completed 66% of the total project volume. It is understood that the first phase of the project is expected to be put into operation before the end of this year. After the project is put into production, annual sales income of RMB 1 billion will be realized, and profits and taxes will be 353 million yuan.
Low porosity clay bricks are made of low aluminum mullite as the main raw material, formed by high pressure molding and high temperature sintering. The main mineral composition is mullite phase, the product has excellent high temperature physical properties and chemical erosion resistance.
Low porosity clay brick stability is good, the degree of erosion does not occur sudden change, than ordinary clay brick life increased by 2 to 3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks 50% to 60% higher than the thermal efficiency of the kiln can be improved.
Low porosity clay bricks are characterized by:
1. Low porosity, 13 to 15%;
2. Load softening temperature is high for about 1472 ℃;
3. High compressive strength at room temperature, generally about 100MPa;
4. Good volume stability at high temperature and good abrasion resistance;
5. good resistance to infiltration and erosion.
Low porosity clay brick as a good clay refractory brick products, so often used in chemical erosion, temperature fluctuations in the environment, such as steel, glass, chemical industry. The effect is quite obvious in the use of glass hot room and the use of iron water tank.
