In early March of 2009, China National Machine Association organized an expert in Anshan to carry out the scientific and technological achievements appraisal of the "two-bath steel-based hot-dip aluminum dipping technology" developed by Anshan Yinma Hot Melt Dip Aluminum Co., Ltd.
The results include surface pretreatment, component preheating, solvent treatment, hot dipping aluminum, and post-treatment technologies. The surface of the steel substrate has three layers of iron-aluminum alloy, pure aluminum, and aluminum oxide. The surface is smooth and dense, and the adhesion is excellent. .
The process adopts vertical immersion furnace, preheating before immersing, slow cooling after infusion, etc. It can perform hot-melting aluminum leaching on the whole steel structure with complex structure and heavy weight, small thermal deformation, uniform thickness of the immersion layer, and the solution Large, elongated pieces of aluminum dipping product process problems.
This achievement has been successfully applied to the Anshan Oil Refinery, Liaohe Oilfield, Liaoyang Petrochemical Fiber Company, and Daqing Petrochemical Corporation's heat exchangers, which can extend the service life of equipment and have good corrosion resistance.
Organization Rack is made of high quality 304 stainless steel, It is easier to clean without rust, safe, healthy and durable, Prevent rust or chemicals from contaminating food and damaging health. Suitable for putting fruits vegetables and bread in kitchen, dining and bar.
