Abstract
The invention relates to an environment-friendly, high-iron-throughput, non-baking iron ditch ramming material and a preparation method thereof, belonging to the field of refractory materials. An environment-friendly high-throughput iron content non-baking iron ditch ramming material, which is composed of the following raw materials in parts by weight: 45-55 parts of brown corundum, 19-27 parts of dense corundum, 11-23 parts of SiC, 0- 8 parts, Si3N40-12 parts, 3-6 parts of active ɑ-Al2O3 powder, 1-5 parts of flake graphite, 3-8 parts of binder, wherein the total number of parts of other raw materials except binder is 100 parts; the binder The composition is as follows: 40-80 parts of carbon-containing resin, 10-40 parts of vegetable oil, 5-15 parts of melamine urea-formaldehyde resin, and 2-8 parts of carbon powder. The environment-friendly anhydrous taphole clay of the present invention has the following advantages: ① less harmful substance content, harmless to human body; ② no smoke and dust, little impact on the environment; ③ high iron flow rate, long service life, and reduced labor intensity of workers.
Description
technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to an environment-friendly, high-iron-throughput, non-baking iron ditch ramming material and a preparation method thereof. Background technique [0002] At present, there are few reports abroad on the research and development of environment-friendly, high-throughput, non-baking iron trench ramming materials and related products. There are still a large number of single-taphole blast furnaces in my country for quite a long time, and the tap channel materials used are traditional ramming materials, which contain many harmful components and cause certain harm to human health and the environment. Many users' understanding of the environment-friendly high-throughput iron-free baking-free ramming material is limited to no smoke or less smoke and dust, so the environment-friendly tapping channel ramming material should have the following three requirements: [000...
