Anti-corrosion compact checker brick for upper part of coke oven regenerative chamber and preparation method thereof
The invention relates to an anti-corrosion compact checker brick for the upper part of a coke oven regenerative chamber and a preparation method of the anti-corrosion compact checker brick. The anti-corrosion compact checker brick is prepared from the following raw materials in parts by weight: 25-60 parts of low-aluminum mullite particles, 15-25 parts of andalusite, 4-6 parts of high-temperaturealuminum oxide micro powder, 10-15 parts of high-purity kaolin fine powder, 10-15 parts of clay and 5-6 parts of a binder. The anti-corrosion compact checker brick has the characteristics of low porosity, high strength, stable high-temperature structure, high refractoriness under load, excellent high-temperature creep resistance, good CO corrosion resistance and the like, solves the problems of checker hole blockage and softening collapse of the coke oven checker brick in the use process, has the performance superior to that of common clay and semi-silicon checker bricks, and can meet the high-temperature requirement of the top of a large coke oven regenerative chamber.
本发明涉及一种焦炉蓄热室上部用抗蚀变致密型格子砖及其制备方法，由以下重量份数的原料组成：低铝莫来石颗粒25‑60份、红柱石15‑25份、高温氧化铝微粉4‑6份、高纯高岭土细粉10‑15份、粘土10‑15份、结合剂5‑6份。本发明具有低气孔，高强度，高温结构稳定，荷重软化温度高、高温压蠕变性优、抗CO侵蚀效果好等特性，解决焦炉格子砖在使用过程中的格孔堵塞、软化坍塌问题，其性能优于一般粘土质、半硅质格子砖，能够满足大型焦炉蓄热室顶部高温的需求。
