Some Suggestions on Refractory Materials Exported to Japan in China
With the enhancement of people’s awareness of environmental protection and the implementation of some new environmental protection regulations, in the future, not only the waste of the refractory itself will be required to be discharged, but also the use of refractory materials in the process of using refractory materials will not be effective. Produce harmful substances that pollute the environment and harm human health. For example, some of Japan's most famous large companies (including Mitsui Shipbuilding and Nippon Steel, etc.) are actively participating in the development of waste incinerator manufacturing technologies. In order to reduce the content of dioxin in the gas discharged from the furnace after incineration, it is generally solved by increasing the incineration temperature in the furnace. As the incineration temperature in the furnace is increased, the erosion rate of the refractory material is accelerated and the service life of the refractory material is shortened. The best way to increase the life of refractories in incinerators is to use high-chromium aluminum chromium refractories. However, when aluminum-chromium refractories are used, harmful hexavalent chromium remains in the slag and the rejected refractories, causing environmental pollution. For this reason, Japan is currently developing new refractory materials for incinerators. Some suggestions for increasing the export of refractories to Japan are due to the continuous recession of the Japanese economy and the appreciation of the yen since 1995. Japanese steel companies have to increase steel product competitiveness in the international market in order to reduce production costs. The increase in imports of refractory materials has led to a surge in the import of refractory materials in Japan. In 1997, it had reached 167,204 tons, of which 72,222 tons were imported from China, accounting for about 43.3% of Japan's total imports of refractory materials.
