Abstract
Description
Technical Field
[0001] This utility model relates to the field of steelmaking technology, specifically to a drying device for slag-reducing agents used in steelmaking. Background Technology
[0002] Steelmaking slag-forming agent, also known as steelmaking refining agent, primarily functions as a slag-forming agent and slag agglomerator in the steelmaking process. Its main components are alumina and calcium oxide, with a high proportion of fluorite. Modern slag-forming agents are a new type of steelmaking slag-forming agent that solves the problems of traditional steelmaking processes that use fluorite for slag forming, which result in environmental pollution due to fluorides, slow dephosphorization and desiliconization effects, and low steel metal yield. Its characteristic feature is that it is an alkaline oxide with a melting point below 1200℃.
[0003] Currently, there are problems with the storage of steelmaking slag-reducing agents. These agents are prone to getting damp, which can cause violent reactions when added during the steelmaking process, potentially leading to accidents and reducing the quality of the steel. Long-term storage can also cause the slag-reducing agents to absorb moisture from the air and form lumps, requiring them to be broken up before use. Utility Model Content

The setting of a stirring component allows the steelmaking slag-reducing agent in the material box to be stirred. The combination of a driven gear, a motor, and a driving gear drives the stirring rod to stir in the material box.

[0012] Optionally, the drying oven has ten ventilation holes on the left side of its inner cavity.
[0013] By adopting the above technical solution, air circulation can be achieved inside the drying oven. At the same time, the small diameter of the vent holes can reduce the outflow of dry air, thereby increasing its residence time inside the drying oven.
[0014] Optionally, both sides of the discharge box are connected to a discharge pipe, and the other end of the discharge pipe is provided with a pipe cover.
[0015] By adopting the above technical solution, it is easier to feed the slag-reducing agent.
[0016] Optionally, inclined plates are fixedly connected to both sides of the bottom of the material box cavity, and the inclination angle of the inclined plates is not less than 15 degrees.
[0017] By adopting the above technical solution, it is convenient to guide and discharge the slag-discharging agent in the material box.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] This invention, by incorporating a drying assembly, enables the drying of steelmaking slag-reducing agents within a material box. The assembly utilizes a fan and heating grid to blow heated air into the drying chamber, heating the surface of the material box and drying the slag-reducing agent through heat conduction.

The combination of a driven gear, a motor, and a driving gear drives a stirring rod to agitate the agent within the material box. The spiral blades facilitate the discharge of the slag-reducing agent from the material box during its forward and reverse rotation. Attached Figure Description
