    实验炉热处理使用知识,下面小编为您讲解一下:
    Experimental furnace heat treatment using the knowledge, the following Xiaobian for you to explain:
    1.实验电炉活动连接部分全部采用O型橡胶圈密封连接,此部分均通水冷却。
    The 1 part of all activities connected experimental electric furnace using O type rubber ring, this part of the water cooling.
    2.实验电炉处理钛合金时,不宜用氮气作为冷却气体,因为钛和氮在高温下反应,形成金黄色的氮化钛。
    2 when the electric furnace is used to treat titanium alloy, it is not appropriate to use nitrogen as the cooling gas, because the titanium and nitrogen react at high temperature to form the golden titanium nitride.
    3.工件在真空状态下淬火,应使用真空淬火油,此油具有较低的饱和蒸气压。
    3 the workpiece is quenched in vacuum, the vacuum quenching oil should be used.
    4.实验电炉的保养应在真空或充纯氮状态下,避免平时不用时吸气,吸潮。
    4 the maintenance of the experimental furnace should be in the vacuum or under the condition of pure nitrogen, usually do not need to avoid inhalation, moisture absorption.
    5.国内实验电炉的压升率应不大于1.33Pa/h,国外某些企业的标准为0.67Pa/h
    5 domestic electric furnace pressure rise rate should not be greater than 1.33Pa/h, the standard of some foreign enterprises 0.67Pa/h
    6.真空加热以辐射为主,工件在炉内应该保持间距。
    6 vacuum heating to radiation, the workpiece should be kept in the furnace spacing.
    7.升温过程中,工件及炉内材料会放气,使真空度下降。
    7 in the process of heating, the workpiece and furnace material will be deflated, so that the vacuum down.
    8.真空回火、真空退火、真空固溶处理及真空时效的加热温度一般与常规处理时加热温度相同。
    8 the heating temperature of vacuum tempering, vacuum annealing, vacuum solid solution treatment and vacuum aging is the same as that of conventional treatment.
    9.真空炉应该具有快冷装置。冷却水的压力应该大于0.2Mpa,流量应可调。
    9 vacuum furnace should have fast cooling device. The cooling water pressure should be greater than 0.2Mpa, the flow should be adjustable.
    10.冷却气体:钢一般采用百分之99.995纯度的氮气,高温合金采用百分之99.999的氮气或氩气,钛合金采用百分之99.995的氩气。
    10 cooling gas: steel is generally used in the purity of nitrogen, high temperature alloy with ninety-nine point nine nine nine percent nitrogen or argon, titanium alloy with ninety-nine point nine nine five percent argon.
