Background technology
Boiler tubing with metal materials such as steel for a long time under the high-temperature water vapor environment work entails can receive the erosion of oxidation; Analyze the structure and the change procedure of oxide film, the best way is that the sample of getting at any time in the actual moving process is analyzed, but the operation of boiler can not stop at any time; Therefore formation mechanism and the forming process that will study oxide film just need be carried out simulated experiment and accomplished; Also is a great laboratory work and how to analyze oxidation mechanism with the actual oxidizing process of simulation, and in order to let experiment more near actual conditions, the high temperature water vapor oxidation device just becomes a kind of needs; The steam oxidation device of announcing now seldom; The apparatus structure that in these devices, has too complicacy causes cost too high, and for example application number is 200910017551.8 patent of invention: metal material high temperature water vapor oxidation experiment device has several level structures; Device is quite complicated, and this will inevitably raise the cost; What have then causes accuracy not high owing to install the problem of design, tower oxidation stove for example commonly used, and device precision can not reach requirement of experiment.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, experimental data again can guaranteed high temperature water vapor oxidation experiment device.
For reaching above-mentioned purpose, the present invention takes following scheme:
A kind of metal material high temperature water vapor oxidation device; It is characterized in that: comprise shell, have temperature sensor in the stove temperature control equipment, have the waterworks of by-pass valve control and be located at the water vapour generating means in the shell and have the high temperature water vapor oxidation stove of top cover; Described waterworks and water vapour generating means have cross current; There is steam channel to be communicated with between described water vapour generating means and the high temperature water vapor oxidation stove; Temperature sensor has control line to be electrically connected with temperature control equipment in the described stove; Described temperature control equipment is through the resistive heater temperature in the resistance wire control circuit control high temperature water vapor oxidation stove; Have temperature sensor jack in steam outlet and the stove on the described top cover, be fixed with the sample hook; The equal insulation material of described water vapour generating means and high temperature water vapor oxidation stove parcel, the top cover groove is left in the top of high temperature water vapor oxidation stove, and temperature sensor also is wrapped in the top cover by insulation material in described sample hook that is connected in top cover and steam outlet, the stove.
Described steam channel is: the water vapour generating means that is in the below is communicated with the high temperature water vapor oxidation furnace bottom through an aperture.
The steam outlet that has on the described top cover is: run through a top cover hollow high-temperature ceramic up and down, can prevent the oxidized erosion of top cover self like this; Described sample hook is attached to hollow steam outlet pipe sidewall, and sample hangs on the hook through the heating resisting metal silk.
Described top cover is higher than the top cover groove, and both can excellent sealing.
Described oxidation furnace inwall employing high temperature oxidation resisting material such as T91 steel, HR3C steel, nickel-bass alloy material etc., insulation material can be selected materials such as asbestos for use.High temperature water vapor oxidation stove design capacity is 5 ~ 10 liters, and water vapour generating means design capacity is 0.5 ~ 1 liter.
During work, earlier sample is hung on the sample hook through the heating resisting metal silk, top cover is covered in the top cover groove, good seal stretches into temperature sensor in the stove through the dedicated channel on the top cover then, sets temperature in the stove subsequently.Open the water flow control valve door of waterworks; The resistance wire circuit of closed oxidation furnace and water vapour generating means; Water in the waterworks becomes water vapour through water flow control valve door entering water vapour generating means and rises to high temperature water vapor oxidation stove and sample generation oxidation reaction, runs off through steam outlet at last.Off resistance silk circuit after the experiment of corresponding time is carried out in insulation, closes waterworks current valve, treats to take out temperature sensor after the whole cooling, mentions top cover and takes off sample and get final product.This apparatus structure is simple; Main oxidation work has only one-level; In addition because the high-temperature water vapor in the high-temperature oxydation stove is the water vapour that comes from the steam generator; More stable than directly in the high-temperature oxydation stove, adding the resulting steam of water, the generation of water vapour also is more prone to, and resulting experimental data is also more reliable.
The present invention has the following advantages and good effect:
The metal material high temperature water vapor oxidation experiment that (1) can realize using in the laboratory;
(2) simple in structure, produce easily, with low cost.
