Description
Technical field
The present invention relates to technical field of alloy, specifically, being related to a kind of kirsite.
Background technology
Ocean about covers 71% earth surface, and marine industries have become the mainstay of current world economy development.
Salinity in seawater is high, oxygen-enriched, and there is a large amount of marine microorganisms and macro biology, in addition sea beat and sunlight,
Marine corrosion environment is more harsh.Marine environment have become influence facility military service safety, the service life, reliability it is most important
Factor causes the great attention of countries in the world government and industrial quarters.
After steel are zinc-plated, corrosion resistance increases substantially, and can save material and resource, plays more good economic effect
Benefit and environmental benefit.Steel make coating by local failure in use, and the steel matrix exposed will soon be corroded
Fall.But the distinctive sacrificing protection performance of galvanized steel can make corrosion rate become very slow.Main cause is that zinc exists with the iron in steel wire
Primary battery is constituted in moist environment, since the standard electrode potential of zinc only has -1.05V, is less than-the 0.036V of iron, thus
Zinc is aoxidized as anode, and iron is protected as cathode.The later product of zine corrosion is very fine and close, and reaction speed is very slow,
So that overall corrosion resistance increases substantially.
Hot-dip is by the method to obtain coating in steel piece immersion molten metal, and the metal as coating is low
Melting point metals.Wherein galvanizing is most widely used.Steel performance after zinc-plated is excellent, the intensity and plasticity of existing base steel, again
There are the strong anti-corrosive properties of zinc coating.Because galvanized layer thickness is big, there are pure zinc layer and fe-zn alloy layer, so corrosion resistance and good.With
Other metal phase ratios, the price of zinc is relatively low, and production cost is low, and technique is suitable for automating, thus productivity is especially high.Separately
Outside, coating belongs to that anodic protection, coating is secured, appearance is beautiful, these advantages make the production capacity of whole world galvanizing be plating
Seven times or so of zinc.
As the requirement to hot dip zinc product inherent quality, presentation quality, use quality is continuously improved, traditional hot-dip
Zinc cannot fully meet the environmental corrosion needs of existing getting worse.Presently, the hot dipping of anti-corrosion ability is had more
Alloy plating system is allumen.In at the international level, develops new zinc-aluminum based alloy and pass through the hot spot for becoming and studying both at home and abroad.It is beautiful
State develops the coating material of Zn-Si in the 50-60 ages, and it is rare earth coated that Belgium in the eighties develops entitled Galfan zinc-aluminiums
Material, nippon iron company developed the Zn-A1-Mg-Si high corrosion-resistant coating that name is Supekdima in 2000
Steel plate, product corrosion resistance are 5-8 times of Galfan coated plates, and notch corrosion resistance is better than Galvalume coating, alternative stainless steel
Plate and aluminium sheet.
The iron pan in galvanizing by dipping field mainly uses outside mode of heating.Zinc pot be welded with low carbon steel plate or cylinder iron cast and
At heat source is placed on zinc pot bottom or both sides and heat is transmitted to zinc liquid by the heat transfer of wall.Casting iron pan is to use gray cast iron
Casting melts zinc amount generally at 2 tons hereinafter, being mainly used for the miniature parts galvanizing such as steel part, bolt.The pot material of steel plate welding
Mostly low carbon low silicon steel plate is used to manufacture.Galvanizing by dipping iron pan is at low cost, manufacturing process is simple, quick heating, easy to maintenance, obtains
Relatively broad application.But when the iron pan of these conventional hot-dip zinc is used for hot dipping of zinc-aluminum alloy, iron pan
Aluminium alloy seriously corroded, service life is extremely short, and improper zinc consumption is big.
There is also a certain distance compared with world standard for the development of China's thermal dip plating of steel zinc.Existing hot dip zinc-aluminium production
Line majority there are backward in technique, product yield is low, poor product quality, production cost are high, energy charge is big, environmental protection measure is ineffective,
The shortcomings of often resulting in Heavy environmental pollution, such production line are difficult to meet the needs of Chinese national economy rapid development.Seek preferably
Hot-dip aluminum zinc technique is one of the critical issue in application study and industrialization.Wherein, hot-dip aluminum zinc crucible is existing
Overcoming for quagmire can make hot dipping of zinc-aluminum alloy expand industry size and improve productivity effect.In the near future, such
Novel hot-dip plating zinc-aluminium will be widely used with iron pan in more hot dipping of zinc-aluminum alloy.
Invention content
The purpose of the present invention is to overcome the deficiency in the prior art, and providing one kind can make under 420-480 degree atmospheric conditions

1.2wt.%,Mo:0.2-0.3wt.%,Ca:0.1-0.2wt.%,Cr:8.0-9.5wt.%,Ni:6.2-7.5wt.%,Si:4.0-
8.0wt.%,Co:1.5-1.8wt.%, B:0.2-0.5wt.%, surplus are iron.The ferroalloy is in fusion process because of volatilization and shape
The weight lost at reasons such as clinkers is in 1.0-2.0wt.% or so.
The preparation method of above-mentioned corrosion-resistant stainless steel pot material used for hot dip galvanizing, includes the following steps：The original that will as above match
Material is added in the electric induction furnace of argon gas protection, and uses silicon carbide crucible；Sensing heating is molten to 1500-1600 degree formation alloy
Liquid, and be sufficiently stirred 10 minutes or so using electromagnetic agitation effect；Alloy liquid is stood 10 minutes in the heat preservation of 1500-1600 degree
After be cast into required billet.The ingot casting of gained is subjected to hot rolling under 800 degree, amount is 10-15% under every time rolling.Often
Intermediate anneal temperature is 900 degree after hot rolling twice, keeps the temperature 1 hour.Material is finally rolled into the steel plate that thickness is 40-60mm,
The iron crucible of galvanizing by dipping can be prepared with these steel plates by way of deforming and welding.Hot dipping of zinc-aluminum alloy
Technique is：Hot-dip temperature is 420-480 degree, and the hot-dip time is 30-60 seconds.
