The fishing steel wire rope of coating, the resistance to corrosion of the coated steel cord of stack pile in natural sea-water compared with zinc-coated wire double with
On.
The material of sea fishery steel wire hot dipping of zinc-aluminum alloy and production technology still have some problems, such as coating at present
Formed product is bad caused by thicker, and production cost caused by dregs are more on continuous zinc coating production line increases etc..Although
Using alloying element is added into molten bath, coating is improved by the type and formation sequence of intermetallic compound in change coating
The type of quality or dregs.But up to the present, aluminum concentration control is bad in hot dipping of zinc-aluminum alloy, can not only improve
Product quality can cause coating table and the defects of particle or even plating leakage occurs instead, especially in batch hot dip production.
Domestic at present very few with zinc-aluminium plating layer research to sea fishery, the relevant technologies that domestic manufactory uses rely primarily on
Import.Metallurgical industry structural adjustment paces in the world's are accelerated, and the center of gravity of production will be shifted from developed country to developing country.At present
China is in process of industrialization, the product of the lasting of each department of national economy, fast development and industrial upgrading to steel products
Kind, more stringent requirements are proposed for quality.The structural adjustment for accelerating China's metallurgical industry will be of great significance.China's steel
There is also a certain distance compared with world standard for the development of galvanizing by dipping.There are technologies to fall for existing galvanization production line majority
Afterwards, zinc consumption is high, product yield is low, poor product quality, production cost are high, energy charge is big, environmental protection measure is ineffective, often results in serious
The shortcomings of environmental pollution, such production line are difficult to meet the needs of Chinese national economy rapid development.Seek better hot-dip aluminum zinc
Material is one of the critical issue in application study and industrialization.Such alloy industrialization can obtain greatly economic and society
Benefit.In the near future, as more engineer application fields are expanded, such novel alloy will be in more galvanizings by dipping
It is used widely.
