Embodiment Construction

[0025] The spray surface widening dephosphorization machine of one embodiment of the present invention, such as figure 1 As shown, it includes: the roller table base 1 set in the phosphorus removal box, the roller table 2 for conveying the slab, the phosphorus removal upper header 3, the phosphorus removal lower header 4, and the phosphorus removal upper header 3 The adjustment device 5, the roller table 2 is arranged on the roller table base 1, and the phosphorus removal upper header 3 and the phosphorus removal lower header 4 are symmetrically arranged above and below the roller table 2. Set the included angle between the nozzle and the base to be 12-15°, and the opening of the included angle faces the direction where the slab enters the phosphorus removal box. At this time, when the nozzle is turned on, the direction of water mist spraying is in line with the moving direction of the slab. An oblique angle is formed to generate an oblique shear force, and the scale on the su...

Abstract

The invention provides a spray surface widening dephosphorization machine capable of effectively monitoring the working state of the nozzle header, which includes: a roller table base installed in the box, a roller table for conveying slabs, and a phosphorus removal upper header , Phosphorus removal lower header, an adjustment device for adjusting the phosphorus removal upper header, the roller table is set on the base of the roller table, the phosphorus removal upper header and the phosphorus removal lower header are symmetrically arranged above and below the roller table, so Both the phosphorus removal lower header and the phosphorus removal upper header include a base and a nozzle, the base is arranged on the roller table base, the nozzle is arranged on the top of the base, and the axis of the nozzle extends The direction and the height direction of the base form an included angle of 12-15°, and the opening of the included angle faces the direction in which the slab enters; the nozzle is provided with a detection sensor, and a monitoring terminal is provided in the background for receiving the slab. The detection signal sent by the detection sensor is used to regulate the water spray volume of the nozzle; the monitoring terminal is connected to the detection sensor by communication.

Description

technical field [0001] The invention relates to the field of continuous casting and rolling equipment, in particular to a spray surface widening dephosphorization machine. Background technique [0002] Continuous rolling mills use bloom or continuous casting billet as raw material. Due to the advantages of continuous casting billet, the physical and chemical properties are more uniform than blooming billet, and it is easy to increase billet weight. Therefore, the proportion of continuous casting billet has gradually increased in recent years. 100% has been reached. The thickness of the slab in the continuous strip rolling mill is generally 150-300mm, and the length is generally 9-12m. The weight of the slab directly determines the unit coil weight. On a modern rolling mill, the unit coil weight has reached 20-30 tons / m. Increasing the coil weight can significantly increase the output and yield of the rolling mill, but it is also necessary to increase the mechanical equipmen...
