Abstract

The invention discloses a removing device and method for cadmia in a furnace nose of a galvanizing line and belongs to the technical field of hot galvanizing. The removing device for the cadmia in thefurnace nose of the galvanizing line comprises a cadmia resisting plate, a first cadmia extracting mechanism and a second cadmia extracting mechanism, wherein the cadmia resisting plate is connectedwith the furnace nose and arranged in a zinc pot; the first cadmia extracting mechanism is arranged on the operation side of the furnace nose and the edge of the zinc pot, the first end of the first cadmia extracting mechanism is arranged in the furnace nose, and the second end of the first cadmia extracting mechanism is arranged at the galvanizing zinc surface position outside the furnace nose; and the second cadmia extracting mechanism is arranged on the drive side of the furnace nose and on the edge of the zinc pot, the first end of the second cadmia extracting mechanism is arranged in thefurnace nose, and the second end of the second cadmia extracting mechanism is arranged at the galvanizing zinc surface position outside the furnace nose. The removing device and method for the cadmiain the furnace nose of the galvanizing line are simple, reasonable, economical, low in cost and failure rate, high in purification efficiency and suitable for being installed and used on a galvanizingproduction line.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing, in particular to a device and method for removing zinc slag in a galvanizing line furnace nose. Background technique [0002] During the production of hot-dip galvanizing, the zinc slag produced in the zinc bath adheres to the steel strip, which affects the surface quality of the coating and reduces the service life of the galvanized steel sheet. Zinc dross can be divided into 3 categories: surface dross, scum and bottom dross. The scum is the main factor that causes strip defects. Part of the scum produced in the strip area inside the zinc pot directly adheres to the strip, and the other part flows back into the furnace nose with the eddy current of the zinc liquid and adheres to the strip, which will affect to the surface quality of the strip coating. Contents of the invention [0003] The invention provides a device and method for removing zinc slag in the nose of a galvanizing...
