Embodiment 2

[0019] Example 2. Such as Figure 2-3 shown. In this embodiment, the processing head 4 is set in the shape of a rectangular knife plate or blade, which can act on the cutting slag in the manner of end-touch contact or plug-in contact. Its transducer, amplifier and processing head are arranged in the cavity of the mouthpiece. Its transducer, horn, processing head and blowing nozzle can be fixed on the cutting trolley. The mouthpiece and its input port connection are constructed of stainless steel. Pressurized gas can be introduced into the mouthpiece from above the mouthpiece. The structure of the rest of the ultrasonic processor in this example and the slag cleaning method can be similar to the above-mentioned embodiment. Mouthpieces and processing heads are set on both sides of the steel.

Embodiment 3

[0020] Example 3 as Figure 4 As shown, in this example, its ultrasonic treatment device includes an ultrasonic generator 1 and a mouthpiece 5 . The ultrasonic wave generated by the ultrasonic generator passes through the inner cavity of the blowing nozzle through the orienter 11 and directly acts on the cutting slag generated by cutting. The operation start time of the slag cleaning treatment device lags behind the cutting operation time of the cutting nozzle by 15-300 seconds . Both the ultrasonic wave and the blowing nozzle correspond to the cutting seam, and are set at the end close to the beginning of the cutting seam of the cut steel. It mainly uses the ultrasonic vibration effect, and also has a certain cavitation effect to carry out strong damage to the cutting slag, and purges and removes the steel slag. The structure of the rest of the ultrasonic processor in this example and the corresponding processing and cleaning methods are similar to those of the above-mentio...

Embodiment 4

[0021] In Example 4, the blowing direction of the blowing nozzle is the same as that of the cutting seam. The ultrasonic sound intensity is 0.5-4W / cm2, and the frequency is 20-30000KHZ. The rest of the structure of the ultrasonic processor and the processing and cleaning method of this example can be similar to the above-mentioned August 1st embodiment.

Abstract

The invention discloses a slag removing method of continuous casting cutting and a device for the slag removing method of the continuous casting cutting. The slag removing method of the continuous casting cutting comprises the following steps that ultrasonic waves or ultrasonic waves and pressure gas are utilized at the same time for slag cutting removal, the ultrasonic waves or the ultrasonic waves and pressure gas are mutually matched in a corresponding manner, and the ultrasonic purging and cleaning is carried out on the cutting slag from the horizontal, the longitudinal and / or the oblique direction; and the device comprises a blowing nozzle, and further comprises an ultrasonic treatment device which corresponds to the blowing nozzle and is arranged on one corresponding side or one end of the cutting position of a steel material. The slag removing method of the continuous casting cutting is simple and convenient, and has a good removal effect, the quality of the cutting surface can be fundamentally improved, and the device is simple in structure.

Description

technical field [0001] The invention relates to a metal cutting, in particular to a continuous casting online cutting slag removal method and a device thereof for steelmaking. Background technique [0002] Due to the lack of cutting slag adhesion treatment technology when the continuous casting slab temperature is high and metal cutting in the continuous casting production process, so far, the cutting slag cleaning produced in the steelmaking and continuous casting online cutting process has always affected the quality of continuous rolling. The impact of cutting slag on the cutting quality of steelmaking follow-up materials requires a lot of time, manpower and energy to clean it up and take additional processing procedures. Serious waste of resources, it is also difficult to realize the automation of steelmaking, continuous casting and rolling production. And make the cost of steelmaking and continuous casting remain high. Contents of the invention [0003] The object o...
