Description

一种基于图像识别的引流砂外接装置及方法An external device and method for drainage sand based on image recognition

技术领域technical field

本发明涉及一种基于图像识别的引流砂外接装置及方法，属于钢铁冶金连铸装置及方法技术领域。The invention relates to an external drainage sand device and method based on image recognition, and belongs to the technical field of iron and steel metallurgical continuous casting devices and methods.

背景技术Background technique

在当前连铸工艺中，钢包自动开浇已经成为连铸整个工艺过程必不可少的一个重要环节。在当前的技术条件下，钢包在回转台悬臂待浇时，首先通过人工将长水口安装在钢包下水口上，再将钢包滑板打开，引流砂在钢水重力及自重的作用下从钢包上水口滑落下来，沿长水口进入中间包中，随后钢水便从钢包中流入中间包中，完成钢包的自动开浇过程。因此在钢包的自动开浇过程中，引流砂不可避免的会进入中间包中，其含有的SiO2、Cr2O3、ZrO2等氧化物如在中间包中不能完全上浮去除，将会进入钢中形成外来夹杂物，严重影响铸坯的质量。In the current continuous casting process, the automatic pouring of ladle has become an indispensable and important link in the whole process of continuous casting. Under the current technical conditions, when the ladle is waiting to be poured on the cantilever of the turret, the long nozzle is first manually installed on the ladle lower nozzle, and then the ladle slide plate is opened, and the drainage sand slides from the ladle upper nozzle under the action of the gravity and self-weight of the molten steel Down, enter the tundish along the long nozzle, and then the molten steel flows from the ladle into the tundish, completing the automatic pouring process of the ladle. Therefore, during the automatic pouring process of the ladle, the drainage sand will inevitably enter the tundish, and the oxides such as SiO 2 , Cr 2 O 3 , ZrO 2 contained in it will enter the tundish if they cannot be completely floated up and removed in the tundish. The formation of foreign inclusions in the steel seriously affects the quality of the slab.

为避免引流砂进入中间包污染钢水，目前已经有学者提出了相关的技术方案，但存在一定的缺点。发明专利《钢包引流砂外导方法及钢包开浇工艺》（申请号CN201810981782.X）公开了一种钢包引流砂外导方法，该方法采用了手动控制支杆的方式外接引流砂，该方法的缺点是全程依靠人工操作，操作人员劳动强度高，安全隐患高。发明专利《一种伸缩式钢包引流砂接收装置》（申请号CN202111203679.0）公布了一种伸缩式引流砂接收装置，该装置可以自动接取引流砂，优点是降低了操作人员的劳动强度，其不足之处是接砂杆收回的时机仍是依靠人眼观察，接砂过程未能完全实现自动化。In order to prevent the drainage sand from entering the tundish and contaminating the molten steel, some scholars have proposed related technical solutions, but there are certain shortcomings. The invention patent "Ladle Drainage Sand Outward Guide Method and Ladle Opening Process" (application number CN201810981782.X) discloses a ladle drainage sand outflow method. The disadvantage is that the whole process depends on manual operation, the labor intensity of the operators is high, and the safety hazards are high. The invention patent "A Telescopic Ladle Drainage Sand Receiving Device" (Application No. CN202111203679.0) discloses a telescopic drainage sand receiving device, which can automatically receive the drainage sand. The advantage is that the labor intensity of the operator is reduced. The disadvantage is that the timing of taking back the sand rod still relies on human eye observation, and the sand connection process has not been fully automated.
