Description
Technical field
The present invention relates to sinking roller preparation field, particularly relate to a kind of pottery sinking roller and preparation method thereof.
Background technology
Galvanizing is also referred to as galvanizing by dipping, is that steel component immerses and obtains the one of metal cladding in melted zinc liquid and prevent
The most economical effective method that ferrous materials corrodes in natural environment.The steel component processed through galvanizing suffers from excellent corrosion resistance in the corrosive environments such as air, seawater, soil.Developing rapidly with high voltage power transmission, traffic, communication career in recent years, more and more higher to steel and iron parts requirement of shelter, galvanizing demand is also continuously increased.
Sinking roller is the critical component of hot-galvanizing equipment.Traditional sinking roller is mainly based on ferrous materials, but due to iron
Low melting point Fe5Zn21 of porosity and looseness and FeZn13 intermetallic compound (being commonly called as cadmia) can be formed in zinc liquid and float in zinc liquid, its resist melt liquid zinc corrosion is very poor, therefore service life is shorter, need to often change, and has a strong impact on being normally carried out of production.The corrosion being additionally, since steel causes zinc liquid to increase iron, has a strong impact on the purity of galvanizing goods.
It is a kind of effective for using process for treating surface to improve ferrous materials sinking roller resist melt liquid zinc corrosion performance
Method.More conventional sinking roller surface treatment method mainly has plating method and thermal spraying.Although plating method has with low cost, the advantage such as simple and easy to do, but use the boride coating that plating method obtains, alloying layer thickness is restricted, the coefficient of expansion difference generating FeB/ two kinds of intermetallic compounds of Fe2 B is the biggest, and the most crisp, the adverse circumstances at liquid zinc corrosion are easy to cracking, and therefore its performance awaits improving further.Thermal spraying is to study sinking roller process for treating surface more, that be more widely applied.The material being currently used for resisting corrosion of molten zinc coating mainly has: WC/Co, CrWMo
With FeCrAl etc..The coating constituted due to these materials has preferable resistance to molten zinc corrosion performance, is thus used in without have received preferable effect under the static working condition of difference variation.While it is true, heat spraying method also has its weak point, the shortcoming of its maximum is that thermally sprayed coating the most unavoidably exists certain porosity, and it is poor, easy to fall off that the diffusion existing for zinc of these holes provides adhesion between diffusion admittance, and coating and matrix.It is therefore desirable to develop coating material and the technology of preparing thereof of new low-cost and high-performance.
