Description

一种电磁输送冷钢的装置A device for electromagnetic conveying cold steel

技术领域technical field

本实用新型涉及钢铁冶金工业连铸技术领域,特别涉及一种电磁输送冷钢的装置。The utility model relates to the technical field of continuous casting in the iron and steel metallurgy industry, in particular to a device for electromagnetically conveying cold steel.

背景技术Background technique

近年来,连铸技术得到了巨大进步,随着拉速不断提高,钢坯中心偏析、疏松等内部质量缺陷逐渐凸显。快速降低结晶器内中心过热度,促使结晶过程在铸坯断面快速均匀进行是消除中心偏析,提高钢坯内部质量的有效手段。连铸结晶器喂钢带技术将钢带插入结晶器内,改变结晶器内温度场的分布,钢带在结晶器内熔融吸热,降低了钢液过热度和铸坯断面温度梯度,使温度分布更有利于等轴晶结晶过程的进行,有利于提高铸坯的形核率,从而提高连铸坯质量,优化铸坯凝固组织,在工业上有良好的应用前景。在中国,部分企业已经完成连铸结晶器喂钢带工艺设备的实验工作,但在喂入钢带过程中会使结晶器液面产生波动,发生卷渣等问题,严重影响连铸坯质量,无法实现工业化大生产。In recent years, continuous casting technology has made great progress. With the continuous increase of the pulling speed, the internal quality defects such as segregation and porosity in the center of the billet have gradually become prominent. Rapidly reducing the degree of superheat in the center of the mold and promoting the rapid and uniform crystallization process in the section of the slab is an effective means to eliminate the center segregation and improve the internal quality of the slab. The continuous casting mold feeding steel strip technology inserts the steel strip into the mold to change the distribution of the temperature field in the mold. The distribution is more conducive to the equiaxed crystal crystallization process, which is beneficial to improve the nucleation rate of the slab, thereby improving the quality of the continuous casting slab and optimizing the solidification structure of the slab, which has a good application prospect in industry. In China, some enterprises have completed the experimental work of the continuous casting mold feeding steel strip process equipment, but during the feeding of the steel strip, the liquid level of the mold will fluctuate, and problems such as slag entrainment will occur, which seriously affects the quality of the continuous casting billet. Industrialized mass production cannot be achieved.

专利公开号CN102974791A公开一种连铸结晶器喂钢带系统,钢带从导向管进入电磁振动器再进入结晶器,在向结晶器送入钢带时,借助电磁铁作用的电磁振动器赋予钢带以强制性谐振。但是电磁振动的导向管会对结晶器保护渣层产生扰动产生卷渣,并且插入的导向管在高温钢液中亦会发生侵蚀损坏,污染钢液。专利公开号CN107900298A公开了一种生产高品质连铸板坯的结晶器喂带装置;钢带穿入喂带引导槽喂入到结晶器的厚度中心位置,不足之处是结构复杂,造成成本的增加,同时存在冷钢进入结晶器时会把钢液表面的保护渣带入到钢液中影响铸坯质量的问题。专利公开号CN206065356U公开了一种连铸结晶器喂带钢用可变渣线的防护装置和连铸结晶器,通过防护装置排开保护渣然后在保护管中直立加入冷钢带。不足之处是露出的钢液会被氧化从而影响铸坯质量。Patent Publication No. CN102974791A discloses a continuous casting mold feeding steel belt system. The steel belt enters an electromagnetic vibrator from a guide tube and then enters the mold. The band is forced to resonate. However, the electromagnetic vibration guide tube will disturb the mold slag layer and cause slag entrainment, and the inserted guide tube will also be eroded and damaged in the high-temperature molten steel, polluting the molten steel. Patent Publication No. CN107900298A discloses a mold feeding device for producing high-quality continuous casting slabs; the steel strip is fed through the feeding belt guide groove and fed to the thickness center position of the mold. The disadvantage is that the structure is complicated and the cost is high. At the same time, when the cold steel enters the mold, the mold flux on the surface of the molten steel will be brought into the molten steel, which will affect the quality of the cast slab. Patent Publication No. CN206065356U discloses a protective device for a variable slag line for continuous casting mold feeding strip steel and a continuous casting mold. The protective slag is discharged through the protective device and then the cold steel strip is added upright in the protective tube. The disadvantage is that the exposed molten steel will be oxidized and affect the quality of the slab.

可见在现有的喂带技术中,一类是直接通过喂钢装置向结晶器内加入冷钢带,该类技术会在喂钢过程中,卷入保护渣而进入铸坯内部影响铸坯质量;另一类是采用排渣装置,如排渣挡板、排渣罩等,该类装置在结晶器上部会占用较大空间,给生产操作带来不便,装置复杂,后期维护成本增加,而且在长期工作中,浸泡于钢液中的避渣装置上的耐耐火材料也会脱落进钢液中影响铸坯质量,同时裸露的钢液会被氧化也影响铸坯质量;最后一类是通过电磁振动的方式减轻粘渣现象发生,但该类振动喂钢对钢液面波动影响很大,卷渣现象严重,仍然会导致铸坯质量下降。It can be seen that in the existing belt feeding technology, one is to directly add cold steel strip to the mold through the steel feeding device. This kind of technology will involve the mold flux and enter the inside of the billet during the steel feeding process, which will affect the quality of the billet. ; The other type is to use slag discharge devices, such as slag discharge baffles, slag discharge hoods, etc. This type of device will occupy a large space in the upper part of the mold, which will bring inconvenience to the production operation, the device is complicated, and the maintenance cost will increase in the later period. In the long-term work, the refractory material on the slag avoidance device immersed in the molten steel will also fall off into the molten steel and affect the quality of the casting billet. At the same time, the exposed molten steel will be oxidized and also affect the quality of the casting billet. The electromagnetic vibration method can reduce the occurrence of slag sticking, but this type of vibration feeding steel has a great influence on the fluctuation of the molten steel level, and the phenomenon of slag entrainment is serious, which will still lead to the decline of the quality of the casting billet.

Under the action of the magnetic field force generated by the coil 9, it moves to the lower nozzle 6 of the tundish, and enters the mold according to the flow of molten steel. The entry of cold steel changes the distribution of the temperature field in the mold, which first solidifies and then melts in the mold, reducing the superheat of the molten steel and the temperature gradient of the slab section, making the temperature distribution more conducive to the equiaxed crystallization process. , which is beneficial to the improvement of the nucleation rate of the slab.
