Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a red-hot steel slag cracking processing device, which solves the problem that the water temperature sprayed from the atomizing nozzle of the existing steel slag cracking device is higher than the water temperature sent in by the water pipe, and the atomization cracking is reduced. The problem of the effect is to ensure that the temperature of the condensed water sprayed by the atomizing nozzles at each position is the same, to avoid the difference in cracking degree caused by the atomization of steel slag at different positions by different condensed water, to improve the overall quality of cracking, and to reduce the difficulty of use. It is convenient to open and control the switch of the discharge bin plate, and the alarm function is added, which can send an alarm when the temperature of the steel slag at the bottom of the cracking furnace is high, so as to ensure that the steel slag is cooled to an appropriate temperature when it is discharged

Abstract

The invention discloses a hot steel slag cracking processing device. The hot steel slag cracking processing device comprises a cracking furnace, wherein a sealing cover plate is installed at the top of the cracking furnace, supporting legs are installed at the bottom of the cracking furnace, and the cracking furnace is provided with a cracking device, a balancing device, a discharging device, and a protection device. The invention relates to the technical field of metallurgical slag treatment. According to the hot steel slag cracking processing device, the purpose of preventing condensate water from being heated in the process of being conveyed to atomization nozzles is achieved, the atomization cracking effect is ensured, the same temperature of the condensate water sprayed out of the atomization nozzles at all positions is ensured, the situation that the cracking degree is different due to the fact that steel slag at different positions is atomized by different condensate water is avoided, the overall cracking quality is improved, and the use difficulty is reduced; and a discharging bin plate switch is convenient to turn on and control, an alarm function is added, an alarm can be given out when the temperature of the steel slag at the bottom of the cracking furnace is high, and the steel slag is guaranteed to be cooled to a proper temperature during discharging.

Description

technical field [0001] The invention relates to the technical field of metallurgical slag treatment, in particular to a red-hot steel slag cracking processing device. Background technique [0002] The steelmaking process is actually a slagging process. The recovery of metal materials in steel slag has been paid more and more attention. A variety of steel slag crushing, magnetic separation, and classification technologies have been successfully developed and applied to recover as much metal material as possible. Among them, steel slag thermal braising technology is used The most, the most promising, the principle of the steel slag hot stewing process is to put the hot steel slag in the stewing tank, and spray water on the surface of the steel slag in the stewing tank, so that the temperature difference between the inside and outside is too large to cause thermal stress, during the autoclaving process The change of ore phase produces phase change stress, etc., so that the stee...
