Description
Technical Field
The invention belongs to the technical field of hot galvanizing, and particularly relates to a silicon-tin alloy contained in a hot galvanizing bath.
Background
With the rapid development of the industries such as communication, electric power, automobiles, ships, household appliances, buildings, breeding industry and the like, the demand of hot galvanizing products is increased year by year, and the requirements on the product quality are continuously improved. The hot galvanizing principle comprises the following steps: cleaning iron rust on the surface of the steel part by acid washing or atmosphere reduction, then soaking the steel part into zinc alloy liquid after solvent treatment and drying or directly soaking the steel part into the zinc alloy liquid; the iron on the surface of the steel part reacts with the molten zinc to form an alloy coating on the surface of the steel structural part. In order to reduce the cost, improve the corrosion resistance, the surface property and the good mechanical property of a hot galvanizing product, reduce the generation amount of bottom slag and reduce the effective zinc waste caused by salvaging the bottom slag, the hot galvanizing alloy technology presents a new development trend.
For example, in the hot galvanizing industry at home and abroad, the alloy coating with trace alloying elements is added, so that the alloy coating has good surface quality, excellent corrosion resistance and excellent bonding performance and mechanical performance. However, with the improvement of the steel production process, the components of the steel are relatively complex, and the change causes the traditional hot galvanizing to have some galvanizing quality problems, such as the phenomenon of over-thick coating, uneven thickness, Sandelin effect, color difference and the like, and meanwhile, the produced bottom slag is more, and the bottom slag is salvaged for many times in the production process, so that more effective zinc is wasted. On the other hand, the plated part has a complex structure and a changeable shape, for example, a large pipe tower part is made of steel materials with high silicon and manganese contents, and the structure is more complex than that of single angle steel, plate materials, flat steel, steel pipes, different types of strip steel and the like, and the structure influences the zinc plating heat transfer and the flow of zinc liquid, influences the adhesion of a plating layer and puts higher requirements on hot galvanizing alloy. The pickling time of large steel parts and complex steel parts is long, and the pickling is partially over-pickled; the over-pickling brings more iron particles into the plating assistant solution and the zinc alloy solution, so that the impurity iron in the zinc alloy solution is increased in the galvanizing process, and more zinc slag is generated. Meanwhile, the structural member has high hot dip coating requirement and needs to be galvanized for a long time, and mainly shows the quality problems of poor zinc bath heat transfer effect, poor zinc bath fluidity, more iron dissolved in a steel member enters zinc alloy liquid, and the thickness of a coating is thicker, the color difference of the coating is generated, the adhesion force of the coating is poor, particles may appear on the coating, the coating is not bright and smooth, zinc slag is increased and the like. In the prior art, the commonly used zinc alloy for hot galvanizing mainly comprises Zn-Al alloy and Zn-Ni alloy, which can not be applied to the surface hot-dip coating process of steel materials with complex components, and can not effectively solve the problem of zinc slag increase caused by the fact that excessive iron particles enter zinc alloy liquid. The hot dip coating is carried out for more than 3 minutes, because the thickness of the coating is increased by iron particles to be more than 180 mu m, the coating becomes brittle, the local adhesive force of a plated part is poor, and simultaneously more bottom slag is generated, so that 3-5% of zinc is wasted and cannot be effectively utilized.
