Stainless steel material intergranular corrosion automatic tester

Abstract

The invention provides a stainless steel material intercrystalline corrosion fully-automatic test instrument. The stainless steel material intercrystalline corrosion fully-automatic test instrument comprises a box body, a control system, and test equipment, wherein the box body is divided into a test area, a heating area and a control equipment area through partition plates; the heating area is positioned on the lower part of the test area; a heating device is arranged in the heating area; the test equipment is placed in the test area; a sliding rack is arranged on the side wall of the test area; a control panel, a timing control module, a state monitoring module, a temperature control module and a test sample control module are mounted in the control equipment area; and the test equipment comprises a test container, a condensation pipe and a hoisting mechanism. The stainless steel material intercrystalline corrosion fully-automatic test instrument solves the problem about automatic control of the intercrystalline corrosion test; and due to the use of the system, the test can be integrally and continuously finished under the condition permissible condition. Even if condition abnormal change occurs, the test can be stopped temporarily, and the test is continued when each condition meets the test control requirement.

Description

technical field [0001] The invention relates to the field of physical and chemical detection of stainless steel materials used in aviation, in particular to a fully automatic tester for intergranular corrosion of stainless steel materials, which is used for the intergranular corrosion test of key stainless steel materials used in aviation power supplies and parts of engine ignition devices. Background technique [0002] The intergranular corrosion test of stainless steel materials is an important test for physical and chemical testing of stainless steel materials. [0003] At present, the test equipment for the intergranular corrosion test of stainless steel materials is mainly composed of a temperature-regulated electric furnace, a ground conical flask, and a serpentine condenser. After the stainless steel sample is treated, put the sample and the corrosion solution into the conical flask with a ground mouth, and heat it with a temperature-adjusting electric furnace to ensu...

AI Technical Summary

Problems solved by technology

[0004] The current test must be carried out under the condition of electricity and water, and the personnel cannot leave for a long time during the test to prevent accidents during the test

At the same time, the existing equipment is fully manual operation, and the components of the test process work independently, without compatibility and safety protection, and the structure is relatively simple

The circulating water cannot be interrupted during the corrosion process, and the heating cannot be automatically stopped and the test time recorded after power failure, water cut-off or corrosion. Operators are required to be on duty, record the time, inspect and adjust the output power of the electric furnace, and check the cooling water supply, which is time-consuming and laborious. Low test efficiency
