Technical Field

[0001] This utility model belongs to the field of rolling mill technology, specifically a new type of direct rolling mill. Background Technology

[0002] As an advanced technology in modern steel production, direct rolling technology has significant advantages such as energy saving, consumption reduction, shortening of process, and reduction of oxidation loss because it eliminates the cooling and reheating process of steel billets. It has become one of the important directions for steel enterprises to achieve green and low-carbon transformation.

[0003] In existing direct rolling mills, the rolls are in direct contact with high-temperature metal, resulting in high roll temperatures. Current technologies dissipate heat from the rolls, such as through air cooling or by spraying water directly onto them. However, this process wastes heat and is not conducive to energy conservation and emission reduction. To address these issues, a new type of direct rolling mill is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of direct rolling mill in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: A novel direct rolling mill includes a frame, on which two rotatable rolls are mounted via bearing seats. Each roll includes a shaft core, and a roll body is fixedly connected to the middle of the shaft core. One end of the roll body has an annular water distribution groove, and the other end of the roll body has an annular water collection groove. Annular sealing plates are fitted onto both sides of the shaft core. The outer ring of the annular sealing plate is sealed to the roll body by bolts, and the inner ring of the annular sealing plate is sealed to the shaft core by bolts. A plurality of water flow channels are formed around the inside of the roll body between the annular water collection groove and the annular water distribution groove. These water flow channels connect the annular water collection groove and the annular water distribution groove. The annular water distribution trough is connected to the shaft core, which has an inlet channel and an outlet channel. The outlet of the inlet channel is located in the annular water distribution trough, and the inlet of the outlet channel is located in the annular water collection trough. A flow-collecting ring is rotatably and sealed on one side of the shaft core. The flow-collecting ring is fixedly installed on the bearing seat of the roller. The inner wall of the flow-collecting ring has an annular inlet channel and an annular return channel. The inlet of the inlet channel is located in the annular inlet channel, and the outlet of the outlet channel is located in the annular return channel. The flow-collecting ring has an inlet hole and a return hole. The inlet hole is connected to the annular inlet channel, and the return hole is connected to the annular return channel.

[0006] In a preferred embodiment, an annular sealing gasket is provided at the connection between the annular sealing plate and the shaft core.

[0007] In a preferred embodiment, an annular sealing gasket is provided at the connection between the annular sealing plate and the roller body.

[0008] In a preferred embodiment, a sealing ring is provided at the rotatable connection between the shaft and the two ends of the bus ring.

[0009] In a preferred embodiment, a sealing ring 2 is provided at the rotatable connection between the shaft and the middle of the manifold to isolate the annular inlet groove and the annular return groove.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, the heat exchange liquid is fed into the annular inlet groove of the manifold ring through the inlet hole. Then, the heat exchange liquid enters the annular distribution groove through the inlet channel, and then enters the annular collection groove through the water flow channel. Finally, the liquid flows back to the annular return groove in the manifold ring through the outlet channel and is discharged from the manifold ring through the return hole, thereby realizing the circulation and heat exchange of the heat exchange liquid. This can effectively dissipate heat from the rolls. At the same time, the heated liquid can be used in other parts of the factory, thereby realizing the recovery and utilization of the heat of the rolls during direct rolling and saving energy.
