Electric furnace top prefabricated part with high thermal shock resistance and preparation process thereof
The invention relates to the technical field of electric furnace top prefabricated parts and discloses an electric furnace top prefabricated part with high thermal shock resistance. The prefabricatedpart comprises the following raw materials in parts by weight: 10-20 parts of sintered mullite with the particle size of 5-8 mm, 10-20 parts of tabular corundum with the granularity of 3-5 mm, 10-20 parts of andalusite with a particle size of 1-3 mm, 10-20 parts of andalusite with the particle size of 0-1 mm, 10-20 parts of andalusite with the particle size being lower than 0.088 mm, 5-10 parts ofactivated aluminum oxide micro powder with the particle size being lower than 0.044 mm, 5-15 parts of corundum fine powder with the particle size being lower than 0.044 mm, 3-8 parts of silicon oxidefine powder with the particle size being lower than 0.005 mm, and 3-8 parts of pure calcium aluminate cement. The invention discloses an electric furnace top prefabricated part with high thermal shock resistance and a preparation process thereof. The material has better thermal shock resistance and is used for resisting a violent fluctuating temperature environment; the furnace top cover has theadvantages of better erosion resistance, longer service life, obvious economic benefit, formation of technical advantages for manufacturers, higher cost performance, longer service life for use units,thinning of the use cost, no need of frequent replacement of the furnace top cover and reduction of the workload of workers.
本发明涉及电炉顶预制件技术领域，且公开了一种抗热震性能强的电炉顶预制件，包括以下重量份数配比的原料：粒度5‑8mm的烧结莫来石10‑20份、粒度3‑5mm的板状刚玉10‑20份、粒度1‑3mm的红柱石10‑20份、粒度0‑1mm的红柱石10‑20份、粒度低于0.088mm的红柱石10‑20份、粒度低于0.044mm的活性氧化铝微粉5‑10份、粒度低于0.044mm的刚玉细粉5‑15份、粒度低于0.005mm的氧化硅细粉3‑8份和纯铝酸钙水泥3‑8份。该抗热震性能强的电炉顶预制件及其制备工艺，具有更好的抗热震性用以抵抗剧烈波动的温度环境，具有更好的抗侵蚀性抵抗钢水的侵蚀，使用寿命更长，同时经济效益明显，对生产厂家来说形成技术优势，具有更高溢价，对于使用单位来说使用寿命更长，摊薄使用成本，且炉顶盖无需频繁更换，降低工人工作量。
