Problems solved by technology

Due to the structural reasons of the existing continuous casting cutting nozzle, the firepower is not concentrated due to the flat injection of gas, which not only makes the cutting gap large, the cutting surface is uneven, the upper edge collapses, and the lower slag hangs, the cutting speed is not high, and the energy consumption is large. High cutting cost
And the slag is easy to stick to the cutting nozzle and block it, resulting in tempering phenomenon, and the cutting nozzle is easy to be damaged

Embodiment Construction

[0015] In order to better understand the technical solution of the present invention, the present invention will be further described through examples and in conjunction with the accompanying drawings. The axial cross section of the output port of the energy storage chamber of the present invention is in the shape of a cone, triangle, trapezoid, funnel or inverted trumpet. The transverse cross-sectional shape of the outlet flow channel is a reverse fan shape. The head of the nozzle core is conical or truncated. The high pressure oxygen hole is in the shape of a truncated cone.

[0016] Such as figure 1 and 2 As shown, in this example, the cutting nozzle body includes a nozzle core 1 and a mouth cover 2 nested in each other, a high pressure oxygen hole 9 respectively arranged on the cutting nozzle body, and an input channel, an energy storage chamber 3 and an Output runner 4. The energy storage chamber 3 is composed of an annular groove on the nozzle core 1 and the inner p...

Abstract

The invention discloses a continuous casting cutting nozzle. It includes interconnected nozzle core and mouth cover, high pressure oxygen hole, and sequentially connected input channel, energy storage chamber and output flow channel. The corresponding parts of the output channel are formed by the radial or longitudinal section of the head of the nozzle core, which is conical, trapezoidal, triangular or irregular trapezoidal grooves and the corresponding parts of the mouth cover. The continuous casting cutting nozzle has simple structure and processing, small volume, concentrated flame, high cutting quality, fast speed and low energy consumption.

Description

technical field [0001] The invention relates to a steelmaking cutting device, in particular to a continuous casting cutting nozzle used for steelmaking continuous casting cutting. Background technique [0002] In steelmaking and continuous casting cutting, the cutting operation of the billet flame cutting machine is completed online and synchronized with the movement of the billet. Due to the limitation of the site and the process, the cutting length of the slab should be as short as possible, so the cutting speed of the cutting nozzle has become a bottleneck for improving the production efficiency of continuous casting, which requires the continuous casting cutting device to have a higher cutting speed. To meet and adapt to the high casting speed of steelmaking and continuous casting production. In addition, with the increasing emphasis on energy, the cutting loss of billets and the quality of the cut section are getting higher and higher, which requires the cutting device...
