渗铝板可分为两类,第一类是以耐热性为主的可以耐640℃左右的高温,它是在低碳钢板的两侧各镀上20-25µm厚的AlSi合金(Si含量为6-8.5﹪)镀层;第二类以耐腐蚀性为主,其镀层是第一类的2-3倍。渗铝板一般以热浸或固体粉末等方法渗铝。第一类耐高温的形成AlFeSi合金层,第二类耐腐蚀形成AlFe合金层。由于耐腐蚀的渗铝板镀层厚熔点低,其焊接性相对较差。由于渗铝板具有较好抗高温、抗氧化和耐腐蚀性,价格便宜,已在我国石油、化工、电力、汽车及轻工部门得到广泛的应用。 Aluminum plate can be divided into two categories, the first type is mainly heat resistance can withstand about 640℃, it is a 20-25 m thick AlSi alloy (6-8.5) coating on both sides of the low carbon steel plate; the second type is mainly corrosion resistance, its coating is 2-3 times that of the first type.Aluminum infiltration plate is generally infiltrated by hot immersion or solid powder.The first type of high temperature resistant forming AlFeSi alloy layer, the second type of corrosion resistant forming AlFe alloy layer.Due to the low thick melting point of corrosion-resistant aluminum permeable plate plating, its soldability is relatively poor.Because the aluminum infiltration plate has good high temperature resistance, oxidation resistance and corrosion resistance, cheap price, has been widely used in China's petroleum, chemical, electric power, automobile and light industry departments. 镀铝钢板的镀铝层是由铝、硅和铁元素组成。经日本的一些机构检测证实,未化学钝化的镀铝钢板符合食品卫生法,对人体的健康无害,可直接应用于食品加工。废旧的镀铝钢板也完全可以循环使用。 The aluminum layer of aluminous steel is composed of aluminum, silicon and iron.Some institutions in Japan have confirmed that the unchemical passivation of aluminum plated steel plate in line with the food hygiene law, harmless to human health, can be directly applied to food processing.Waste aluminized steel plate can also be fully recycled. 镀铝钢材的用途甚广。最初开发的Ⅰ型镀铝钢板主要用于汽车的排气管和消声器。Ⅱ型主要用于建筑物的屋顶板和侧壁以及一些化工容器。新工艺生产的镀铝钢丝有望用作输电用钢芯绞线而取代目前的镀锌钢丝。镀铝钢管已大量用于电厂锅炉水冷壁管、蒸汽管道、热交换器等。镀铝钢结构尖已大量用于输电铁塔、告诉公路护栏等。 Aluminized steel is of a wide range of use.The originally developed type I aluminum-plated steel plate was mainly used for automotive exhaust pipes and mufflers.Type is mainly used in the building roof panels and side walls as well as some chemical containers.The aluminized steel wire produced by the new process is expected to be used as transmission core wire to replace the current galvanized steel wire.Aluminium-plated steel pipe has been widely used in power plant boiler water wall pipe, steam pipe, heat exchanger, etc.Aluminized steel structure tip has been widely used in the transmission tower, tell the highway guardrail, etc. |
