Embodiment Construction

[0020] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The strip steel 6 enters the zinc pot 10 through the furnace nose, passes through the sinking roller 7 and moves upwards to complete the hot-dip process; Nose tip stretches in the zinc pot 10). Such as figure 1 A hot-dip galvanized furnace nose with the function of spraying and releasing zinc ash is shown, including a furnace nose body 11, a heating and heat preservation system arranged at the lower part of the furnace grate body, and an injection system arranged at the upper part of the furnace nose body 11, And release system; The injection system includes and N 2 The blowing pipe 3 connected by the supply pipeline and the spraying head arranged at the end of the blowing pipe 3, the spraying head extends into the inside of the furnace nose body 11 and is arranged circumferentially ...

Abstract

The invention discloses a hot-dip galvanizing furnace nose with the function of spraying and dissipating zinc ash. Diffuse system; the injection system includes and N 2 The blowing pipe connected by the supply pipeline and the spraying head arranged at the end of the blowing pipe, the spraying head extends into the furnace nose body and is arranged along the circumference of the inner wall, and the spraying direction of the spraying head is downward along the axis of the furnace nose body; The radiating system includes a radiating outlet pipe arranged on the furnace nose body between the heating and heat preservation system and the injection head, and the radiating outlet pipe communicates with the inside of the furnace nose body. The beneficial effects of the present invention are as follows: the present invention designs a blowing system and is equipped with a dispersing system, which can regularly perform purging and dispersing operations on the inner wall of the furnace nose body, and the zinc ash accumulated on the inner wall can be taken away by dispersing the outlet pipe and the transition material , effectively reducing the enrichment of zinc ash on the inner upper surface of the furnace nose.

Description

technical field [0001] The invention relates to the technical field of continuous hot-dip galvanizing of steel strips, in particular to a hot-dip galvanizing furnace nose with the function of spraying and releasing zinc ash. Background technique [0002] In recent years, with more and more hot-dip galvanized sheets entering the market of high-end home appliance sheets and automobile sheets, customers' requirements for the quality of hot-dip galvanized sheets have also further increased. Conversely, the surface quality of galvanized products also affects and restricts the development of hot-dip galvanizing enterprises; zinc dust and zinc slag defects jointly restrict the product quality of hot-dip galvanizing units. [0003] The strip steel needs to go through the annealing furnace before entering the zinc pot. Since the zinc liquid surface in the furnace nose area continuously volatilizes zinc vapor, the zinc vapor condenses in the cooler area of ​​the furnace (furnace nose,...
