Description
Lightly calcined dolomite is mainly used in steelmaking to improve the fluidity of steel slag and is used as a slagging agent. The dataset includes primary raw materials, auxiliary materials, energy, atmospheric emissions, and waste from the production process; infrastructure such as equipment manufacturing and plant construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data derived from multiple sources. The production process of lightly calcined dolomite includes procedures such as feeding, vibrating feeding, mixing, charging, calcination, discharging, and screening. Calcination is typically conducted at high temperatures (800°C to 1000°C), during which part of the carbon dioxide in dolomite is released, thereby converting it into reactive calcium oxide.
Activity Description
The production process of calcined dolomite includes steps such as feeding, vibrating feeding, mixing, spreading, calcination, discharging, and screening. It is typically calcined at high temperatures (800°C~1000°C), during which part of the carbon dioxide in dolomite is released, converting it into reactive calcium oxide.
Process Description
Light-burned dolomite is a type of marble that has undergone high-temperature processing. By calcining dolomite at elevated temperatures, new mineral crystals are formed, thereby altering its physical and chemical properties. After light burning, the hardness and density of dolomite increase. It is primarily used in steelmaking to enhance the fluidity of molten slag and serves as a fluxing agent.
