Problems solved by technology

In the production process, there are basically two types of binders for domestic anhydrous clay: one is based on asphalt and coke powder; the other is to use phenolic resin as a binder to produce clay. Blast furnace clay basically uses tar-bonded clay, which is based on cost considerations. Once heated, the combined tar of this clay will release a large amount of benzopyrene smoke, which will deteriorate the working environment, and benzopyrene is a Extremely strong carcinogen, extremely harmful to the health of workers

Embodiment 1

[0016] Take the following components by mass percentage: 50-60% of high-alumina aggregate, 10-20% of Guangxi white clay, 5-10% of kyanite, 3-8% of sericite, 3-5% of bentonite, high-alumina refractory fine powder 10~20%, binder 8~15%, humectant 0.2~0.5% and plasticizer 0.1~0.3% for later use, high alumina aggregate, Guangxi white clay, kyanite, sericite, bentonite, high The aluminum refractory fine powder and the binder are stirred and bundled for more than 24 hours to obtain the base material. The amount of the binder added is 30-40% of the total amount of the binder formula; continue to add the remaining binder and humectant to the base material and plasticizer for wet mixing and rolling; the above wet mixture is put into the extruder to extrude and cut into pieces for packaging, and then packed in a film bag, then packed in a carton, and then placed on a wooden pallet to become a product.

Embodiment 2

[0018] Take the following components by mass percentage: 50-60% of high-alumina aggregate, 10-20% of Guangxi white clay, 5-10% of kyanite, 3-8% of sericite, 3-5% of bentonite, high-alumina refractory fine powder 10~20%, binder 8~15%, humectant 0.2~0.5% and plasticizer 0.1~0.3% for later use, high alumina aggregate, Guangxi white clay, kyanite, sericite, bentonite, high The aluminum refractory fine powder and the binder are stirred and bundled for more than 24 hours to obtain the base material. The amount of the binder added is 30-40% of the total amount of the binder formula; continue to add the remaining binder and humectant to the base material and plasticizer for wet mixing and rolling; the above wet mixture is put into the extruder to extrude and cut into pieces for packaging, and then packed in a film bag, then packed in a carton, and then placed on a wooden pallet to become a product.

Embodiment 3

[0020] Take the following components by mass percentage: 50-60% of high-alumina aggregate, 10-20% of Guangxi white clay, 5-10% of kyanite, 3-8% of sericite, 3-5% of bentonite, high-alumina refractory fine powder 10~20%, binder 8~15%, humectant 0.2~0.5% and plasticizer 0.1~0.3% for later use, high alumina aggregate, Guangxi white clay, kyanite, sericite, bentonite, high The aluminum refractory fine powder and the binder are stirred and bundled for more than 24 hours to obtain the base material. The amount of the binder added is 30-40% of the total amount of the binder formula; continue to add the remaining binder and humectant to the base material and plasticizer for wet mixing and rolling; the above wet mixture is put into the extruder to extrude and cut into pieces for packaging, and then packed in a film bag, then packed in a carton, and then placed on a wooden pallet to become a product.

Abstract

The invention discloses smoke-free environment-friendly stemming. The smoke-free environment-friendly stemming is prepared from the following component in percentage by mass: 50 to 60 percent of high-aluminum aggregate, 10 to 20 percent of Guangxi white clay, 5 to 10 percent of kyanite, 3 to 8 percent of sericite, 3 to 5 percent of bentonite, 10 to 20 percent of high-aluminum refractory fine powder, 8 to 15 percent of binding agent, 0.2 to 0.5 percent of moisturizer and 0.1 to 0.3 percent of plasticizer. Meanwhile, the invention also discloses a preparation method of the smoke-free environment-friendly stemming. Compared with the prior art, the smoke-free environment-friendly stemming disclosed by the invention has the advantages that a production technology is simple and moderate in cost; in addition, no smoke is released in the use process, so better environment-friendly performance is realized; the smoke-free environment-friendly stemming is good in flushing resistance, good in plasticity and proper in body density, is not easy to broach and is easy to open and block; the phenomena of including iron, breaking iron notches and the like are avoided; besides, the smoke-free environment-friendly stemming can be directly installed for using without baking, and is short in heated hardening time; stemming removal can be realized by blocking for 5 minutes; the smoke-free environment-friendly stemming is more convenient to operate and excellent in slag-resistant performance, so that comprehensive energy consumption is greatly reduced and the working environment is greatly improved.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a smokeless and environment-friendly gun clay and a manufacturing method thereof. Background technique [0002] In recent years, with the macro-control of the state, while the iron and steel industry has decapacity, the state also requires the blast furnace to be large-scale, and resolutely banned the "ground strip steel" production enterprises and production equipment. Blast furnace steelmaking has become the mainstream production process. In the process of blast furnace steelmaking, anhydrous taphole mud for tapping and slag outlet is required and the amount is relatively large. In the production process, there are basically two types of binders for domestic anhydrous clay: one is based on asphalt and coke powder; the other is to use phenolic resin as a binder to produce clay. Blast furnace clay basically uses tar-bonded clay, which is based on cost consideratio...
