Description

Technical Field

[0001] The utility model relates to the technical field of steel cooling, in particular to a rapid cooling structure for H-shaped steel. Background Art

[0002] H-shaped steel is named because of its shape similar to the letter "H". H-shaped steel is mainly manufactured by hot rolling. Hot-rolled H-shaped steel reasonably allocates the aspect ratio of the cross-sectional size according to different uses. It has excellent mechanical properties and superior performance. It is widely used in construction, industry and other fields. Hot-rolled H-shaped steel needs to be cooled after manufacturing before the next process can be carried out. Hot-rolled H-shaped steel needs to be cooled with the help of a cooling device when cooling.

[0003] However, when cooling H-shaped steel, the cooling method is mainly one of air cooling or water cooling, and the steel needs to be transported to the cooling structure through the conveying structure for cooling. There will be a long conveying distance before cooling, and the time in the conveying process is wasted, resulting in a longer overall cooling operation time, which is not conducive to saving working time. In addition, due to the current pressure of cost reduction and efficiency improvement, all new production lines and existing production lines are improving production efficiency. Since the steel wastes a lot of time during the conveying process, in order not to delay the next operation, the cooling time of the hot-rolled H-shaped steel on the cooling bed in the cooling area is shortened accordingly. Short cooling time will bring uncontrollable high temperature to the next process or increase the cooling intensity to bring a series of negative effects such as quenching and cooling bending. Therefore, a rapid cooling structure for H-shaped steel is proposed, which is cooled while the steel is conveyed, and cooling and conveying are carried out simultaneously, thereby preventing time waste and allowing the steel to be fully cooled to solve the above problems.

The steel is cooled by mist cooling, natural cooling and water cooling. The cooling is carried out in three stages, so that the steel section is gradually cooled, and the cooling effect of the steel section is better.

During atomizing cooling, the water in the atomizing cooling box 4 forms water mist under the action of the atomizing nozzle 9 and the water pump. As the steel enters the box 1, the water mist falls on the high-temperature steel to cool it, thereby initially reducing the temperature of the steel. As the roller 2 moves, the natural wind sprayed by the air cooling box 5 cools the steel naturally, further reducing the temperature of the steel, and finally the steel moves to the bottom of the spray pipe 11 The high-pressure nozzle 12 sprays the cooled cooling water to cool the steel, and the high-pressure water flow washes the steel, and finally reduces the temperature of the steel. Compared with the traditional device, the steel is cooled by mist cooling, natural cooling and water cooling in sequence. The cooling is carried out in three stages, so that the steel is gradually cooled, and the cooling effect of the steel is better, which prevents the steel from being affected by insufficient cooling. At the same time, the box body 1 is installed on the roller 2 for conveying steel for cooling. With the transportation of the steel, the cooling is gradually carried out, and the conveying time of the steel is converted into its cooling time. The cooling and conveying are both possible, and the cooling time is saved. The steel is cooled during the conveying process, which does not affect the time of the next process. It is more convenient to use and saves time.
