搪瓷管是一种耐腐蚀、耐磨损、表面光滑不易积灰的换热元件,采用低碳钢管为基体,瓷釉掺入新型材料,按一定的科学配方混合均匀,锅炉配件供应厂家,涂在钢管外表面,然后在高温下烧结成不破碎、无裂纹、耐酸碱腐蚀、耐烟气冲刷、表面光洁度高、烟气流通阻力小,不易堵灰的复合管。在解决锅炉尾部烟道受热面腐蚀、烟气脱硫脱硝受热面改造和各种腐蚀性气体环境中的受热面改造中得到广泛应用。
搪瓷管空预器优点:①耐腐蚀②不易粘灰阻力小③耐磨损。
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), 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,锅炉配件供货商, 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,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,广东锅炉配件, 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,锅炉配件厂家, measuring tool, GB/T9711.1 enamel tube, such as pieces of rolling bearing and carburizing, after tempering hardness is commonly HRC58-64.
