Jetting face widened dephosphorizing machine

Abstract

The invention provides a jetting face widened dephosphorizing machine which can effectively monitor the working states of nozzle headers. The jetting face widened dephosphorizing machine comprises a roller table base arranged in a box body, a roller table used for conveying plate blanks, an upper dephosphorizing header, a lower dephosphorizing header and an adjusting device used for adjusting theupper dephosphorizing header. The roller table is arranged on the roller table base. The upper dephosphorizing header and the lower dephosphorizing header are symmetrically distributed above and belowthe roller table. The upper dephosphorizing header and the lower dephosphorizing header both comprise bases and nozzles. The bases are arranged on the roller table base, the nozzles are arranged at the top ends of the corresponding bases, the included angle between the axis extension direction of each nozzle and the height direction of the corresponding base ranges from 12 degrees to 15 degrees,and the openings of the included angles face the feeding directions of the plate blanks. The nozzles are provided with detection sensors, a monitoring terminal is arranged on the background and used for receiving detection signals sent by the detection sensors and regulating the water jet capacity of the nozzles, and the monitoring terminal is in communication connection with the detection sensors.

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...

Problems solved by technology

[0006] The above-mentioned patent can only detect whether there is water sprayed from the water nozzle during operation, and cannot detect other working conditions of the water nozzle. The intensity of spraying to the surface of the slab affects the phosphorus removal effect
