Embodiment 1

[0010] A processing technology for sintered felt, in which No. 1 roller (1) and No. 1 pair of rollers (2) are arranged on one side of the processing table (4), and No. 2 pair of rollers (6) are arranged on the other side of the processing table And the No. 2 roller (7), the interlayer net (5) passes through the No. 2 pair of rollers, passes through the top of the processing table and then passes through the No. 1 pair of rollers, and its end is wound on the No. 1 roller; when processing, start the No. 1 roller The roller drives the interlayer net to rotate, and after wrapping it around the No. Wind the interlayer net several times around the roller, and visually check that the interlayer net on the No. 1 roller has no obvious protrusions and the structure is tight; dry-spread cotton (3), which is made of 304 material in the following examples, and lay it on the workbench. On the interlayer net, after the dry-laid cotton is spread over the interlayer net at the position of the ...

Embodiment 2

[0012] A processing technology of sintered felt (1) One side of the processing table is provided with No. 1 roller and No. 1 counter-roller, and the other side of the processing table is provided with No. No. 1 pair of rollers passes through the top of the processing table and then passes through No. 1 pair of rollers, and its end is wound on No. 1 roller; during processing, start No. , spread a layer of iron-chromium-aluminum foil on the interlayer net above the workbench, and lay a layer of 2mm thick stainless steel plate on the iron-chromium-aluminum foil, and wrap the No. After the net has no obvious protrusions and the structure is tight; spread the dry-laid cotton (the following examples are all made of 316L material) on the interlayer net at the position of the workbench, and after the dry-laid cotton is covered with the interlayer net at the position of the workbench, again Turn the No. 1 roller, and the dry-laid cotton will be drawn into the No. 1 roller together with...

Embodiment 3

[0014] A processing technology of sintered felt (1) One side of the processing table is provided with No. 1 roller and No. 1 counter-roller, and the other side of the processing table is provided with No. No. 1 pair of rollers passes through the top of the processing table and then passes through No. 1 pair of rollers, and its end is wound on No. 1 roller; during processing, start No. , spread a layer of iron-chromium-aluminum foil on the interlayer net above the workbench, and lay a layer of 2mm thick stainless steel plate on the iron-chromium-aluminum foil, and wrap the No. After the net has no obvious protrusions and the structure is tight; spread the dry-laid cotton (all made of iron-chrome-aluminum in this example) on the interlayer net at the workbench position, and after the dry-laid cotton is fully spread on the interlayer net at the workbench position, again Turn the No. 1 roller, and the dry-laid cotton will be drawn into the No. 1 roller together with the interlayer...

Abstract

The invention relates to a processing technique for a sintered felt, firstly a roller I is started to drive an interlayer net to rotate, ferrum-chromium-aluminium foil is paved on the interlayer net above a working table, and a stainless steel plate is paved on the ferrum-chromium-aluminium foil; dry cotton is paved on the interlayer net; after the dry cotton covers the whole interlayer net, the dry cotton is rolled into the roller I together with the interlayer net; and after the dry cotton paved on the working table completely enters the paired roller I, the roller I stops rotating, cotton loading is continued, and after all interlayer net in the position of the working table is paved with the cotton, the roller I is started again; until the diameter rolled up by the roller I is large enough and does not exceed the diameter of a sintering furnace, the stainless steel plate is paved on the interlayer net on the working table, and the roller I is rotated to wrap the whole coil of cotton; then the roller I wound with the cotton is tied up; the cotton is sintered after being wound and finally is cooled, then hydrogen, argon or nitrogen is filled, and the cotton is placed after the temperature is lowered to about 100 DEG C or is directly subjected to gas quenching until reaching the room temperature, thus completing preparation. The sintered felt prepared according to the invention is good in structure and excellent in use effect.

Description

Technical field: [0001] The invention relates to the field of material processing, in particular to a processing technology of sintered felt. Background technique: [0002] The current metal sintered felt has been successfully used in the fields of chemical industry, metallurgy, aviation and other fields such as filtration, separation, flame retardant, explosion-proof, heat transfer, heat exchange, etc. It has uniform and stable filtration accuracy, high mechanical strength, good rigidity, and durability. Grinding and heat resistance are excellent. The general preparation method of metal sintered felt includes three steps: cotton blending, pressure sintering, and rolling. Sintered felts of different specifications can meet different needs of different customers for pressure, thickness, and strength. Existing sintered mats generally have the disadvantages of high processing cost and low processing efficiency, which are not conducive to popularization and use of products. I...
