Thermal mechanical calculation revealed that the highest compressive stresses concentrated above half way up the snorkels due to the overlap of vertical and hoop stresses. In the case of upper snorkel, the concentrated compressive stresses correspond to areas just above the tuyeres. In addition, the upper snorkel lining would also subject to vigorous lifting gas stirring and cooling, which would add extra thermal stresses and accelerating the erosion of the working lining3. The initial thermal stresses could reach such a level forming micro-cracks and weakening the hot face structure, which would be easily penetrated by steel or slag, leading to fast wear. Bricks with increased stiffness and high thermal expansion coefficient would intensify the thermal stresses at the initial stage of the campaign. A higher preheating temperature and well soaked lining will reduce the compressive stresses at the first heat. |

| 熱力學(xué)計(jì)算表明，因?yàn)榇怪焙铜h(huán)向應(yīng)力的重疊作用，最高的壓應(yīng)力集中在連通管的上半部分。在連通管的上半部分，壓縮應(yīng)力正好集中對(duì)應(yīng)于風(fēng)嘴以上的區(qū)域。此外，上側(cè)連通管襯里也會(huì)受到劇烈升降氣體攪拌和冷卻，這會(huì)施加額外的熱應(yīng)力并促進(jìn)工作襯里的侵蝕【3】。最初的熱應(yīng)力可能會(huì)達(dá)到足夠水平，導(dǎo)致形成微裂紋并削弱熱面的結(jié)構(gòu)，這會(huì)很容易被鋼或渣穿透，導(dǎo)致快速磨損。磚通過增加剛性和高熱膨脹系數(shù)會(huì)加大熱應(yīng)力在初始階段的活動(dòng)。較高的預(yù)熱溫度和浸泡良好的襯里會(huì)降低初熱的壓縮應(yīng)力。 |
