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 a zinc ash blowing and diffusing treatment function. The hot-dip galvanizing furnace nose comprises a furnace nose body, a heating and heat preserving system arranged at the lower part of the furnace nose body, a blowing system arranged at the upper part of the furnace nose body, and a diffusing system; the blowing system involves a blowing pipe communicated with a N2 supply pipeline and a blowing head arranged at the end of the blowing pipe, wherein the blowing head extends into the interior of the furnace nose body and is arranged in the circumferential direction of the inner wall of the furnace nose body, and the blowing direction of the blowing head is downward along the axis direction of the furnace nose body; and the diffusing system involves a diffusing leading-out pipe on a furnace nose body arranged between the heating and heat preserving system and the blowing head, and the diffusing leading-out pipe communicateswith the interior of the furnace nose body. The hot-dip galvanizing furnace nose with the zinc ash blowing and diffusing treatment function has the beneficial effects that the blowing system is designed and the diffusing system is provided, so that the inner wall of the furnace nose body can be periodically subjected to blowing and diffusing operation, zinc ash accumulated on the inner wall can be taken away by virtue of the modes of diffusing leading-out pipe and a transition material, so that the enrichment of the zinc ash on the upper surface of the interior of the furnace nose is effectively reduced.

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,...
