Clay brick with high heat conductivity coefficient for coke oven and preparation method of clay brick
The invention provides a high-heat-conductivity-coefficient clay brick for a coke oven and a preparation method of the high-heat-conductivity-coefficient clay brick, and relates to a metallurgical coke oven clay brick. The clay brick comprises the following raw materials in parts by weight: 45-53 parts of flint clay particles, 6-15 parts of high-thermal-conductivity raw material particles, 10-25 parts of flint clay fine powder, 15-20 parts of silica fine powder, 5 parts of silica powder and 2-5 parts of a paper pulp solution. By optimizing the addition amount of the high-thermal-conductivity phase and controlling the content of the high-thermal-conductivity phase, the problem that the fire resistance of the clay brick is reduced due to addition of excessive high-thermal-conductivity materials can be avoided, and the thermal conductivity coefficient of the clay brick for the coke oven is improved, so that the coking efficiency is improved; in order to solve the problems, such as easy sintering and cracking, existing in the preparation process after the high-thermal-conductivity phase is added, the preparation process is optimized, it is guaranteed that the prepared clay brick has good fire resistance and thermal conductivity, and the service life is prolonged.
本发明提出一种焦炉用高导热系数黏土砖及其制备方法，涉及一种冶金焦炉黏土砖；黏土砖包括以下重量份的原料：焦宝石颗粒45‑53份、高导热原料颗粒6‑15份、焦宝石细粉10‑25份，硅石细粉15‑20份、硅微粉5份、纸浆溶液2‑5份；本发明通过优化高导热相的添加量，控制高导热相的含量，可以避免添加过多高导热材料导致黏土砖耐火性能下降的问题，提高了焦炉用黏土砖的导热系数，从而提高了成焦效率；针对添加高导热相后制备工艺存在的问题，如易烧结、开裂等，进行制备工艺的优化，保证制备后的黏土砖具有良好的耐火性能和导热性能，延长了使用寿命。
