Problems solved by technology

With people's gradual awareness of the toxicity of coal tar and asphalt and full attention to their health, some people proposed to use resin instead of coal tar. The initial solution was considered to be environmentally friendly and pollution-free. The gun mud has less smoke, but its internal phenol and formaldehyde monomers have also been listed as dangerous substances in the ranks of CMR products, which also cause great harm to the human body and the environment.

Abstract

The invention relates to an environment-friendly anhydrous tamping plug and a preparation method thereof and belongs to the field of fireproof materials. The environment-friendly anhydrous tamping plug comprises the following components by weight: 15-20 parts of coke, 22-43 parts of bauxite, 0-10 parts of brown aluminum oxide, 20-25 parts of silicon carbide, 0-8 parts of silicon nitride, 0-3 parts of silicon metal, 10-15 parts of clay, 3-6 parts of sericite and 15-20 parts of a binding agent, wherein the total parts of all materials, except for the binding agent, is 100 parts; the binding agent is composed of the following raw materials in parts by weight: 20-60 parts of carbon-containing resin, 20-50 parts of vegetable fat, 10-40 parts of linear phenolic resin and 5-10 parts of carbon powder. The environment-friendly anhydrous tamping plug has the following advantages of (1) being low in harmful substance content and harmless to a human body; (2) being free of smoke dust and hardly affecting the environment; (3) meeting the use requirements of flushing and casting operation of a blast furnace.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to an environment-friendly anhydrous taphole clay and a preparation method thereof. Background technique [0002] At present, the anhydrous taphole mud used in front of most blast furnaces in China is not really environmentally friendly anhydrous taphole clay. Moreover, many users' understanding of environmentally friendly anhydrous taphole clay is limited to no smoke or less smoke and dust, and they have no concept of the content of harmful substances in the taphole clay used and its harmlessness to human health. There are only a few manufacturers in China that produce environmentally friendly anhydrous taphole clay, which contains many harmful ingredients, causing certain harm to human health and the environment. Therefore, the truly environmentally friendly anhydrous taphole clay should meet the following three requirements: [0003] 1) The content of h...
