SiC Refractories for Waste Incinerator

图片
The working temperature of the waste incinerator for processing garbage is generally not more than 1200 ℃, but the gas (CI2, So2, CO, etc.) generated by the incineration of garbage will cause a severe chemical attack on the refractory materials. In a wider temperature range, SiC refractories materials have higher mechanical strength and wear resistance. SiC Refractory Bricks Refractories for I ncinerators Refractory materials for incinerators are roughly divided into refractory bricks and unshaped refractory materials (overall refractory materials). The former is mainly clay bricks, high alumina bricks, silicon carbide bricks . The latter is mainly composed of clay, high-alumina, silicon carbide castables and clay, high-alumina refractory plastics. With the large-scale technology and resources of waste incinerators, refractory materials of incinerators have also undergone tremendous changes. The furnace temperature of the incinerator combustion chamber is as high a...

Recycling of Some Waste Refractory Materials

In general, most of the treatment methods for waste bricks in the production process of refractory manufacturers and old refractory bricks dismantled by steel mills are piled on one side. In this way, it will occupy the place and pollute the environment. In recent years, the recycling of waste refractory materials has attracted much attention. One problem that cannot be ignored is that there are many types of refractory materials. In the steel industry alone, there are more than 100 types of waste refractory materials. How to make better use of waste refractory materials? First, the chemical composition of the refractory materials must be classified, and then the corresponding treatment. The specific operations are as follows: (1) Waste high alumina bricks (including mullite bricks and corundum bricks) Waste high-alumina bricks can be processed into fine powder for the production of refractory mortar . Particulate materials can be used in the production of various high-...
