河北钢铁集团邯钢的环保纯无铬钝化处理的家电镀锌板DX53D+Z-TC，经检验，各项性能完全满足客户要求，主要用于高端家电制造，是邯钢用纯无铬钝化工艺生产的深冲家电镀锌板，市场前景广阔。

Hebei Iron and Steel Group Handan steel environmental protection pure chromium free passivation treatment of home appliances galvanized plate DX53D + Z-TC, after inspection, the performance fully meet customer requirements, mainly used for high-end home appliances manufacturing, is Handan steel with pure chromium free passivation process production of deep flush home appliances galvanized plate, broad market prospect.

据了解，环保纯无铬钝化是采用有机硅类和无机盐等成分配制的环保钝化液，经过镀锌钝化工艺处理，最终在表面形成一层钝化薄膜，这层薄膜在起到耐腐蚀效果的同时，关键在于能够明显改善镀锌钢板的冲压成型性，降低冲压开裂风险。目前，家电制造企业对钢板的环保、成型要求越来越高，环保纯无铬钝化镀锌产品将逐步取代现在的三价铬钝化产品。据悉，邯钢家电板主要供给美的、格力、海尔等家电企业。

It is understood that environmental protection pure chromium passivation is using organic silicon and inorganic salt composition of environmental protection passivation liquid, after galvanized passivation process, eventually form a layer of passivation film on the surface, the film in the corrosion resistance effect at the same time, the key is to significantly improve the stamping molding of galvanized steel plate, reduce the risk of stamping cracking.At present, home appliance manufacturing enterprises on the steel plate environmental protection, molding requirements are getting higher and higher, environmental protection pure chromium-free passivated galvanized products will gradually replace the current trivalent chromium passivation products.It is reported that Handan Steel home appliance plate mainly supply the United States, Gree, Haier and other home appliance enterprises.

以热轧带钢为基板的热镀锌产品具有生产成本低廉、可生产厚规格2.0-6.0毫米产品等优势，且这些优势是冷基镀锌板很难具备的。在新能源汽车结构件、高端家电外置件、建筑结构件、高速公路护栏、仓储等领域，热基镀锌占有重要位置，且正在逐渐取代价格较高的冷基镀锌板。据了解，现阶段国内仅有极少数钢厂可批量生产，热基镀锌板具有表面质量高、力学性能和成形性能优良、生产成本低的显著特点，受到市场的广泛关注。

Hot coated galvanized products with hot rolled strip steel as the substrate have the advantages of low production cost, production specifications of 2.0-6.0 mm products, and these advantages are difficult to have in cold based galvanized plate.In new energy vehicle structural parts, high-end home appliances external parts, building structural parts, highway guardrail, storage and other fields, hot based galvanized occupies an important position, and is gradually replacing the high price of cold based galvanized plate.It is understood that at the present stage, only a few domestic steel mills can be mass-produced, hot-based galvanized plate has high surface quality, excellent mechanical properties and forming performance, low production cost of significant characteristics, widely concerned by the market.
