Description
技术领域 technical field
本实用新型涉及热镀锌设备领域，特别涉及一种用于锌液净化处理工艺的锌液恒温流槽。The utility model relates to the field of hot-dip galvanizing equipment, in particular to a zinc liquid constant-temperature launder used for the zinc liquid purification process.
背景技术 Background technique
热镀锌是迄今为止钢材防蚀方法中应用最普遍和最有效的工艺措施。现代化连续热镀锌工艺生产的热镀锌钢板广泛应用于轻工、家电、建筑和汽车行业。热镀锌板除了耐蚀性、强度、深冲性等方面的要求外，对表面质量的要求也越来越高，而镀层锌渣缺陷是热镀锌板的主要质量缺陷之一。Hot-dip galvanizing is by far the most common and effective process measure used in steel corrosion protection methods. Hot-dip galvanized steel sheets produced by modern continuous hot-dip galvanizing processes are widely used in light industry, home appliances, construction and automobile industries. In addition to the requirements for corrosion resistance, strength, and deep drawability of hot-dip galvanized sheets, the requirements for surface quality are also getting higher and higher, and the defect of zinc slag in the coating is one of the main quality defects of hot-dip galvanized sheets.
在钢板热镀锌过程中，由于溶剂的反应、空气的氧化、锌锅的浸蚀、带钢表面铁粉和钢基的溶解等，都会使相当数量的铁进入锌液中，并与锌及锌液中的铝等元素发生反应生成锌渣。锌渣根据成分、结构、密度和尺寸的不同，在锌液中可以呈底渣、面渣和浮渣等不同状态。锌渣的形成不仅消耗大量的锌，一旦沉积或粘连在沉没辊或钢板上会严重影响热镀锌板的表面质量，因此避免锌渣缺陷对于高质量热镀锌板的生产十分关键。目前，针对锌渣主要采取“防”的办法，如严格控制锌浴温度和浸镀时间等工艺参数、采用感应加热或内加热陶瓷锌锅代替铁质锌锅等，目的是抑制Fe的溶解和Fe-Zn反应速度，从源头上减少锌渣的形成。而一旦锌渣形成以后，最常见的措施是通过手工或机械装置从锌液表面捞取面渣。捞渣不仅对危害性大的底渣和浮渣无能为力，还不可避免随锌渣夹带出大量的纯锌，造成锌这一紧缺资源的巨大浪费。During the hot-dip galvanizing process of steel sheets, due to the reaction of solvents, the oxidation of air, the corrosion of zinc pots, the dissolution of iron powder and steel base on the surface of strip steel, etc., a considerable amount of iron will enter the zinc liquid and combine with zinc and Elements such as aluminum in the zinc solution react to form zinc slag. Zinc dross can be in different states such as bottom dross, surface dross and scum in the zinc liquid according to the composition, structure, density and size. The formation of zinc dross not only consumes a large amount of zinc, but once it is deposited or adhered to the sinking roll or steel plate, it will seriously affect the surface quality of the hot-dip galvanized sheet. Therefore, avoiding zinc dross defects is very critical for the production of high-quality hot-dip galvanized sheets. At present, "prevention" measures are mainly adopted for zinc slag, such as strictly controlling the process parameters such as zinc bath temperature and immersion time, and using induction heating or internal heating ceramic zinc pot instead of iron zinc pot, etc., the purpose is to inhibit the dissolution of Fe and Fe-Zn reaction speed, reduce the formation of zinc slag from the source. Once the zinc slag is formed, the most common measure is to fish the surface slag from the surface of the zinc liquid by manual or mechanical means. Slag fishing is not only helpless to the harmful bottom slag and scum, but also inevitably entrains a large amount of pure zinc with the zinc slag, resulting in a huge waste of zinc, a scarce resource.
中国发明专利申请号为200710044702.X公开了一种去除热镀锌液中锌渣的复合净化装置，该装置包括锌液输送装置、一级过滤器和二级电磁除渣装置，其中锌液输送装置包括锌液泵和锌液流槽。使用时在锌液泵的作用下不断抽取锌锅内的锌液到净化流槽内，分别流经一级泡沫陶瓷过滤器和二级电磁除渣装置，从而达到连续去除锌渣的目的。但在该装置的净化流槽中未提供温度补偿，锌液流经净化流槽的过程中不可避免产生温度损失，由此带来的温降对钢板热镀锌作业造成干扰。The Chinese invention patent application number is 200710044702.X discloses a compound purification device for removing zinc slag in hot-dip galvanizing bath, which includes a zinc liquid conveying device, a primary filter and a secondary electromagnetic slag removing device, wherein the zinc liquid conveying The device includes a zinc liquid pump and a zinc liquid launder. When in use, under the action of the zinc liquid pump, the zinc liquid in the zinc pot is continuously extracted into the purification launder, and then flows through the primary foam ceramic filter and the secondary electromagnetic slag removal device, so as to achieve the purpose of continuously removing zinc slag. However, temperature compensation is not provided in the purification launder of the device, and temperature loss is inevitable when the zinc liquid flows through the purification launder, and the resulting temperature drop interferes with the hot-dip galvanizing operation of the steel plate.
