搪瓷管空气预热器的优点
搪瓷管空气预热器凭借自身的优势,锅炉配件供应厂家,已经被广泛的应用,今天小编就带领大家先来熟悉下搪瓷管空气预热器的优势:
(1)耐腐蚀:搪瓷管空气预热器的耐酸度比金属管要高出数百倍。
(2)耐磨损:据有关资料证明,搪瓷釉层的维氏硬度HV=652,而金属Q235A钢的维氏硬度HV=114,可见搪瓷的耐磨性要大大超过金属Q235A钢。
(3)阻力小、传热好:根据有关资料,搪瓷管表面粗糙度为0.005mm,而Q235A钢管表面粗糙度为0.2mm,是搪瓷管的40倍。因此,搪瓷管表面光洁度高,不易粘灰,烟气流通阻力小,灰污热阻小,锅炉配件大全,传热系数大。
以上就是搪瓷管空气预热器的优势,如有疑问欢迎询问,我们将竭诚为您解答。
中温回火(250-500度)中温回火所得组织为回火屈氏体。其目的是获得高的屈服强度,弹性极限和较高的韧性。
Medium temperature tempering (250-500 degrees),锅炉配件厂家, medium temperature tempering income group as tempered troostite. Its is to obtain high yield strength, elastic limit and high toughness.
因此,它主要用于各种GB/T9711.1搪瓷管和热作模具的处理,回火后硬度一般为HRC35-50。
Therefore, it is mainly used for various kinds of GB/T9711.1 enamel tube and hot mould processing, after tempering hardness is HRC35-50 commonly.
低温回火(150-250度)低温回火所得组织为回火马氏体。其目的是在保持淬火钢的高硬度和高耐磨性的前提下,西藏锅炉配件,降低其淬火内应力和脆性,以免使用时崩裂或过早损坏。
Low temperature tempering (150-250 degrees), low temperature tempering the organization for the tempered martensite. Its aim is to keep a hardened steel under the premise of high hardness and high wear resistance, decrease the quenching stress and brittleness, lest when using split or premature failure.
它主要用于各种高碳的切削刃具,量具,GB/T9711.1搪瓷管,滚动轴承以及渗碳件等,回火后硬度一般为HRC58-64。
It is mainly used for cutting all kinds of high carbon cutting, measuring tool, GB/T9711.1 enamel tube, such as pieces of rolling bearing and carburizing, after tempering hardness is commonly HRC58-64.
