Test piece-hanging frame for testing high-pressure kettle

Abstract

The invention discloses a test piece-hanging frame for testing a high-pressure kettle, which comprises an alumina ceramic column and two alumina ceramic round struts. The top of the ceramic column (6) is provided with a groove (1) to be hung on a top cover of a high-pressure kettle, the middle round strut (2) penetrates through and is fixed in a round hole (4) in the middle of the ceramic column (6), the bottom round strut (5) penetrates through and is fixed in a round hole (3) at the bottom of the ceramic column (6), the two round struts are respectively used for hanging test pieces of a corrosion test, two test pieces can be hung on either round strut for parallel test research, and the round struts are designed in positions of different heights so that the test pieces are arranged in different medium areas during the test. The invention provides the test piece-hanging frame which is convenient to test the high-pressure kettle under test conditions of 350 DEG C and approximate 19.0 MPa and must use an alumina ceramic material to resist high temperature and high pressure. The test piece-hanging frame has the advantages of convenient use, simple structure and reliable performance.

Description

technical field [0001] The invention relates to a test piece hanger for high temperature corrosion test, in particular to a test piece hanger for autoclave test. Background technique [0002] At present, autoclave is used for high temperature and high pressure corrosion test, and there is no special corrosion test piece hanger, and the test conditions of autoclave are as high as 350 ° C and nearly 19.0 MPa. Therefore, during the test, some are hung with iron wires, and some are hung with self-made glass hooks. The former will cause the reaction between the iron wire and the test piece or cause the iron ions to dissolve in the medium solution during the test. The latter often cannot stand the high temperature and partly occurs melt. Not only is it inconvenient, but also the consistency of test conditions cannot be guaranteed, which brings unnecessary test interference environment. Contents of the invention [0003] The technical problem to be solved by the present inventi...
