Testing apparatus used for researching dissected sintering process, and application method thereof

Abstract

The invention relates to a testing apparatus used for researching a dissected sintering process. The testing apparatus comprises a sintering pot body which is characterized in that: a built-in cylindrical sleeve is arranged on a bar grate in the sintering pot; the cylindrical sleeve is formed by two semi-cylindrical sleeves; the height of the cylindrical sleeve is set as that: when the cylindrical sleeve is placed on the bar grate in the sintering pot, the upper level of the cylindrical sleeve is aligned with the port of the sintering pot; a separating plate is arranged at the middle part of the cylindrical sleeve; supports are symmetrically arranged on the bottoms of the semi-cylindrical sleeves; and the cylindrical sleeve bar grate is placed on the supports. The application method comprises steps that: the sintering pot is arranged on an air pumping pipeline; a layer of asbestos ropes is paved on the bottom between the sintering pot and the sleeve; the gap between the sintering pot and the sleeve is filled by heated sand; a sintering mixture is fed in the sleeve, and is ignited; sintering and air pumping are carried out; after sintering, nitrogen is delivered in the sleeve, and cooling is carried out by blowing; epoxy resin is filled into one side of the sleeve separating plate, and the state of the other side is maintained; at the side that is not filled with epoxy resin, stratified sampling is carried out from bottom to top; and the samples are used in chemical analysis; the side that is filled with epoxy resin forms a half of a complete sintering cake, which can be used in dissection and microscope observation analysis.

Description

Technical field: [0001] The invention relates to the field of metallurgical sintering, in particular to a sintering test device. Background technique: [0002] In terms of sintering test technology, the sintering cup test device is usually used to detect the sintering performance of iron ore and explore the sintering process parameters. After the test started, the sintered material added with fine-grained fuel was mixed and granulated, and added to the grate bar in the sintering cup, and the upper end of the material surface was flush with the mouth of the sintering cup (such as figure 1 shown), then move the igniter to the top of the sintering cup to ignite, and at the same time, the bottom of the sintering cup starts to draw air, creating a certain negative pressure under the grate, and the air is sucked away through the sintering material layer from top to bottom, and the surface of the material layer catches fire The combustion zone gradually moves to the lower material...
