A hot-dip galvanizing system without sinking rolls

Abstract

The invention discloses a sinking-roller-free hot galvanizing system. The sinking-roller-free hot galvanizing system comprises two lower supports; the two lower supports are symmetrically arranged ona base plane; upper supports are arranged at the upper parts of the two lower supports correspondingly; each upper support on the same side where the corresponding lower support is located is arrangedon the corresponding lower support in an up and down sliding manner; two conveying rollers are arranged on the upper supports; two conveying rollers are arranged on the lower supports; and a turningroller is arranged at the lower parts of the two conveying rollers on the lower supports. A traditional hot galvanizing system is creatively innovated from a principle, a traditional sinking roller iscancelled, and a sinking-roller-free mode is used for galvanizing, so that a principle defect of a traditional hot galvanizing mode can be avoided effectively; galvanizing zinc of hot galvanizing issupplied circularly, so that the purpose that a zinc pot does not have zinc slag is achieved, the manpower consumption is reduced effectively, the production cost is saved, and the production efficiency is improved; and with the adoption of the sinking-roller-free hot galvanizing system, the quality of the surface of strip steel can be guaranteed effectively, so that the surface scratching rate can be reduced, the rejection rate of coiled strip steel can be reduced obviously, and the yield is increased.

Description

technical field [0001] The invention relates to a hot-dip galvanizing system, in particular to a sinking-roller-less hot-dip galvanizing system, which belongs to the technical field of metallurgical equipment. Background technique [0002] Hot-dip galvanized sheet is a large amount of sheet and strip products. Traditional hot-dip galvanized products are mainly carried out by using a zinc pot, in which a sinking roller is set in the zinc pot, and the strip steel is dipped into the zinc pot by the sinking roll and removed from the zinc pot. In order to achieve the purpose of galvanizing the surface of the strip steel, this traditional method requires regular cleaning of the zinc pot and the shutdown of the production line, which consumes a lot of manpower and material resources. The zinc slag generated in the pot is very easy to adsorb on the surface of the strip and scratch the surface of the strip; in addition, the sinking roll set in the zinc pot in the traditional producti...

Problems solved by technology

[0002] Hot-dip galvanized sheet is a large amount of sheet and strip products. Traditional hot-dip galvanized products are mainly carried out by using zinc pots, in which sinking rolls are set in the zinc pots, and the strip steel is immersed in the zinc pot by using the sinking rolls and removed from the zinc pot. In this way, the surface of the strip steel can be galvanized, but this traditional method needs to regularly clean the zinc pot, requires the production line to be shut down, and then consumes a lot of manpower and material resources for cleaning, and the zinc The zinc slag generated in the pot is very easy to adsorb on the surface of the strip and scratch the surface of the strip; in addition, the sinking roll set in the zinc pot in the traditional production process is a necessary key component, but the existence of the sinking roll has a great impact on the surface of the strip. Roughness and final quality have a great impact. Once the process parameters are not set properly, production accidents such as scratches are very likely to occur, which will eventually lead to the serious consequences of scrapping the entire strip

[0003] To sum up, the traditional zinc pot has many principle defects in the process and equipment. Although a large number of improved researches have been carried out on the above-mentioned traditional process in recent years, the effect is minimal because the principle process has not changed. Therefore, It is necessary to study the hot-dip galvanizing system in principle in order to fundamentally solve the above technical problems
