Dust particles generated on a back surface of a substrate as a result of polishing by a polishing tool are also forced out toward an outer periphery of the polishing tool by centrifugal force. Then, nitrogen gas is ejected from an ejection port. This forces the dust particles adhering to the back surface of the substrate to separate from the back surface of the substrate. The dust particles are sucked through a suction port. This makes the dust particles less likely to remain on the back surface of the substrate, so that it is possible to increase the rate of removal of the dust particles generated as a result of polishing.

This application provides a method for preparing ferrocoke using zinc-containing dust and lean coal, belonging to the fields of iron and steel metallurgy and low-carbon ironmaking technology. The method uses zinc-containing dust and lean coal as raw materials, adding 10% medium-temperature coal tar pitch as a binder by weight of the total ferrocoke. During the ferrocoke preparation process, the metallic elements and their oxides in the zinc-containing dust can promote the reaction between carbon and CO2 at high temperatures, making carbon more easily consumed. Simultaneously, Zn volatilizes and migrates under high-temperature reducing conditions, making the local carbon structure loose and gradually forming interconnected pore structures around the dust particles. These pores facilitate the entry of CO2 gas into the ferrocoke to participate in the reaction, while also helping the generated gas to be discharged in a timely manner, thereby reducing mass transfer resistance. Through this effect, not only is the gasification reaction process accelerated, but the overall reaction performance of the ferrocoke is also improved, giving it higher gasification efficiency, making it suitable for blast furnaces, reducing the coke ratio, and improving smelting efficiency.
