氧氮氢分析仪的常见故障及解决方法

供电正常、通讯正常，点击确认键后分析仪不工作。这是没有水流，炉子温度太高或仪器通道电压不正常。如没有水流，炉子温度太高这些信息会显示在显示器画面上，但没有信息显示说明这两项正常。接下来检查仪器通道零位电压，如果比±3V高出1V以上，可能是因为气瓶空了，或者是空气进入到分析仪中。检查并更换化学试剂，如果有空气进入热导池里，热导池的电压就会＜-6V，此时打开右面的门，堵住炉子气体进口，10s后，热导池电压值必然升高。经过逐一排查，**终确认碱石棉有问题，更换后仪器正常。 山西美国LECO氧氮氢分析仪优惠价格可选六轴可旋转触摸屏幕，增强了操作的工效和直观性。

Summary

The determination of the amount of oxygen, nitrogen, and hydrogen in iron, steel, nickel-, and cobalt-base alloys represents some of the most important quality metrics for these materials. Oxygen is used to create steel from pig iron by removing excess carbon. Oxygen content must be controlled to limit the amount of carbon monoxide that can be formed during solidification which may cause excessive porosity. Nitrogen is considered both an impurity as well as an important alloying agent. Itcan be present as a nitride or interstitially in its gaseous form. Increased nitrogen content is known to increase yield and tensile strength, thus decreasing ductility and formability. Excessive levels may evolve during solidification thus increasing porosity. High hydrogen content is the primary cause of embrittlement, blistering and flaking due to its high

mobility through the lattice and provides no potential alloying benefits. The ONH836 utilizes a high-power

electrode furnace to quickly and efficiently release the target gases from within the sample, which allows

for a very rapid simultaneous determination of oxygen, nitrogen, and hydrogen.

Procedure - Solid Samples

Instrument calibration/drift correction.

Add approximately 0.05 g of *** Graphite Powder to a *** Graphite Crucible.

Firmly place the crucible on the lower electrode tip or appropriate autoloader position.

Press the Analyze button on the instrument screen, the lower electrode will close and the analysis sequence will start and end automatically.

Repeat steps 3b through 3j a minimum of three times for each calibration/drift standard used.

Calibrate/drift following the procedure outlined in the operator's instruction manual.
