Description
【Technical field】
The invention belongs to steel surface chemical heat treatment technology field, and in particular to a kind of steel surface heat of raising utilization rate of zinc
Processing is with zinc-plated dose.
【Background technology】
Outdoor steel structure and fastener, freeway guardrail, bridge, the steel such as hot-water heating utensil, architectural hardware, automobile, engineering machinery
The iron and steel parts used in the engineering such as iron parts, sintered metal product and chemical industry, ocean, metallurgy, generating, it is often necessary to
Corrosion-resistant overcoat.Zinc is most-often used chemical element in steel and iron parts surfacecti proteon：Dip galvanized, thickness is typically in 15-
130 μm, member planar has significant difference with corner thickness of coating, and lack of homogeneity is difficult to control；Electro-galvanized layer, thickness typically exists
5-25 μm, plane coating uniformity is good, but the coating of component inside cavity is thin, and sometimes without coating；Thermal spraying zinc layers, thickness one
As be 84-300 μm, also thick can reach 3mm, thickness evenness is poor, and compactness is low；Sherardizing layer, thickness be solely dependent upon zinc-plated dose,
The technological parameters such as heating-up temperature and soaking time, it is substantially unrelated with the shape of component and position, be threaded when processing, groove and
During the steel and iron parts of the complicated shapes such as endoporus, the thickness of zinc coat is almost identical, and general thickness can be selected between 10-100 μm,
It is accurately controlled in by adjusting soaking time near a certain thickness value.
Sherardizing, is that sherardizing agent and steel and iron parts are co-located in sealing container, is heated to 400 DEG C or so, makes work
Property zinc atom is internally permeated by the surface of steel and iron parts, and the process of uniform zinc-iron alloy layer is formed on its top layer.Relatively
In other method, the zinc consumption of sherardizing is low, save raw material；Production process is pollution-free, and working condition is good；Production equipment
Simply, using low with maintenance cost.Sherardizing has that corrosion resistance is strong, hardness in the zinc-iron alloy layer that steel and iron parts surface is formed
The advantages of high, wear-resistant, scratch resistance, paintability are good.
Burn into corrosion is the natural enemy of ferrous materials.It is lost it is estimated that world's output of steel there are about 1/10th in burn into rust
Erosion.It was verified that under a variety of environment such as marine atmosphere, severe industrial atmosphere, the corrosion resistance of zinc coat is better than galvanizing, electricity
Zinc-plated and stainless steel.Several Thiourea Derivatives on Zinc Plate Surface Vickers hardness can reach 250-400, and galvanizing, electrolytic zinc-coated steel sheet ironware surface are pure
Zinc, coating Vickers hardness is only 70 or so, therefore zinc-plated compared with galvanizing and electrogalvanizing, the surface abrasion resistance of steel and iron parts and anti-
Abrade performance much better.In general, the pre-treatment of zinc-plated production is only with shot-blasting machine derusting edible vegetable oil, and is removed with cloth bag
Dirt.Sherardizing technology is oozed for the solid of zinc, is produced without zinc fume, and workpiece enters in closed utensil again with sherardizing agent
Row infiltration and separation, do not pollute to surrounding environment.According to measuring and calculating, the zinc consumption of hot-galvanized steel ironware ton product is 100 kilograms
Left and right, and sherardizing is only 30 kilograms or so, only accounts for the 30% of galvanizing.In addition, also corroding this galvanizing without zinc pot
Hard nut to crack.The zinc coat of galvanizing production is uniform, and is one-level with the adhesion of paint, and composite protective can be realized after japanning,
Its corrosion resistance is superior to galvanizing, electrogalvanizing and single zinc coat.Steel product through zinc-plated processing does not influence the power of material
Learn performance.The temperature of zinc-plated processing is lower than galvanizing 100-280 DEG C, and the hydrogen atom that steel matrix is sucked at a temperature of this has spread ease
Go out.Therefore the harm without hydrogen embrittlement in the application, is also avoided that some high intensity parts such as spring mechanics caused by treatment temperature height
The drawbacks of hydraulic performance decline.So, sherardizing has broad application prospects.
But, the zinc-plated time that existing sherardizing agent and its technique for applying need is long；Zinc-iron alloy layer it is corrosion-resistant
Performance can also be improved further；Steel and iron parts surface is bonded with zinc-plated dose, it is necessary to clear up；Used sherardizing agent caking, no
It is easy to recycling.
