Baking-free castable for Maerz lime kiln
The invention provides a Maerz lime kiln baking-free castable, which is prepared from the following raw materials in parts by weight: 10 to 15 parts of white corundum aggregate, 18 to 20 parts of brown corundum aggregate, 18 to 20 parts of mullite aggregate, 6 to 8 parts of ceramic silicon carbide aggregate, 6 to 7 parts of Guangxi white mud, 13 to 15 parts of silica powder, 8 to 10 parts of aluminum silicate cement, 3 to 6 parts of aluminum powder, 0.1 to 0.5 part of water reducing agent and 0.1 to 0.5 part of explosion-proof fiber. According to the baking-free castable for the Maerz lime kiln, cement is formed after the raw materials are mixed by adding water according to the proportion of the raw materials of the castable, the cement is hydrated to be alkaline, the raw materials comprise aluminum powder, the aluminum powder can react with hydroxyl ions which enable the cement to be alkaline to generate hydrogen, a large number of small bubbles are formed in cement paste, water is consumed, and the cement paste is heated to the room temperature. Therefore, moisture in the castable is discharged from the castable through the gas channel along with gas, and the problems that in the prior art, the construction period is long and the cost is increased due to the fact that the Maerz lime kiln castable needs to be baked for a long time are solved.
本发明提供一种麦尔兹石灰窑免烘浇注料，包括如下重量份的原料，白刚玉骨料10～15份，棕刚玉骨料18～20份，莫来石骨料18~20份，陶瓷碳化硅骨料6～8份，广西白泥6～7份，硅微粉13～15份，硅酸铝水泥8～10份，铝粉3～6份，减水剂0.1~0.5份，防爆纤维0.1~0.5份。本发明提供一种麦尔兹石灰窑免烘浇注料，通过上述浇筑料原料的配比，加水使原料混合后形成水泥，水泥水化呈碱性，而原料中包括铝粉，铝粉会与使水泥呈碱性的氢氧根离子反应产生氢气，在水泥浆中形成大量小气泡，并且消耗水分，形成排气通道，从而浇注料里面的水分随着气体从气体通道从浇注料中排出，解决现有技术中麦尔兹石灰窑浇注料需要长时间烘烤带来的工期时间长以及增加成本的问题。
