Problems solved by technology

[0002] Honeycomb ceramics is an important key component in the field of environmental protection and energy saving. Various manufacturers have always used mullite, cordierite or corundum with good thermal shock resistance and high refractoriness as the best raw materials for making honeycomb ceramics. Because mullite The anti-slag and anti-corrosion properties of stone and cordierite raw materials are not very good, so that the service life of the current honeycomb ceramics is very short. The low-level production can only be used for 6-8 months, and the quality can only be used for 10-12 months. Especially Those whose furnace temperature is higher than 1300℃, or use dirty gas, SO 2 In the case of high corrosive substances such as CO, phosphate, etc., some honeycomb ceramics will be pulverized and collapsed after being put into use for about one month, or they will be completely stuck and blocked by iron oxide slag.

Embodiment 1

[0012] The aluminum chromium slag is put into a ball mill and pulverized into a fine powder of aluminum chromium slag, 8% binder and appropriate amount of water are added, kneaded, and then the mud is vacuum smelted, extruded, dried, and fired into honeycomb ceramics.

Embodiment 2

[0014] Take aluminum chromium slag and mullite with 80% of aluminum chromium slag and put it into a ball mill to crush into aluminum chromium slag fine powder, add 6% binder and appropriate amount of water, knead, and then carry out vacuum refining and extrusion Shaped, dried and fired into honeycomb ceramics.

Embodiment 3

[0016] Take aluminum chromium slag and cordierite with 15% aluminum chromium slag, put them into a ball mill and pulverize into fine powder, add 7% binder and appropriate amount of water, knead, then carry out vacuum refining, extrusion molding, drying, Fired into honeycomb ceramics.

[0017] Example 3

[0018] Take the aluminum-chromium slag and the sillimanite, andalusite and kyanite three-stone mixture with 55% of the aluminum-chromium slag and put it into a ball mill and pulverize it into a fine powder, add 9% of the binder and an appropriate amount of water, knead, and then carry out Vacuum smelting, extruding, drying, and firing into honeycomb ceramics.
