And the circulating water pump station, the water adding pump station and the production and living water pump station are used for producing fresh water in a plant area, wherein the water adding pump station adopts a steam heat source to prepare the fresh water into hot water according to the sintering process requirement and is used for adding water in the mixing machine process.
