Abstract

The invention relates to an environment-friendly high-iron-flux baking-free tapping channel ramming material and a preparation method thereof, belonging to the field of refractory materials. The environment-friendly high-iron-flux baking-free tapping channel ramming material is prepared from 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 of Si powder, 0-12 parts of Si3N4, 3-6 parts of active alpha-Al2O3 powder, 1-5 parts of flake graphite and 3-8 parts of a bonding agent, wherein the total parts of all the other raw materials except the bonding agent is 100 parts; the bonding agent comprises the following components in parts by weight: 40-80 parts of carbon-containing resin, 10-40 parts of vegetable oil and fat, 5-15 parts of melamine urea-formaldehyde resin and 2-8 parts of carbon powder. An environment-friendly anhydrous tamping plug disclosed by the invention has the advantages that (1) the anhydrous tamping plug has small content of harmful substances, so that harms to the human body can not be caused; and (2) the anhydrous tamping plug does not have smoke and dust, so that the influence to the environment is small; (3) the anhydrous tamping plug has high iron flux and long service cycle, and can be used for reducing the 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: [00...
