In the current operational facility, due to the absence of pellet pot facility, a novel technique is developed wherein the pellets with different chemistries prepared in the laboratory are fired in an induration machine by placing them inside the Inconel baskets. In the present work, an attempt is made to optimize the pellet chemistry by developing 2 different flux pellets, viz., low basicity (B2: CaO/SiO₂ = 0.3) pellets and high basicity (B2 = 0.9) pellets, and further the effects of basicity on pellet properties, viz., cold compressive strength, porosity, swelling index, reducibility index, and softening and melting temperature, are studied. It has been found through the multiple operational trials that increasing the basicity of pellets from 0.3 to 0.9 results into improving the pellet strength, reducibility and softening and melting characteristics. Moreover, it is observed that the swelling index of pellets is reduced by adding 2% MgO to both low and high basicity pellets that could be attributed to the formation of high melting point slag in pellets. The operational trial has resulted into producing pellets that exhibit a combination of desired mechanical strength, improved swelling, and reducibility index and possess better softening–melting behavior among all the chemistries studied.

在目前的运营设施中，由于没有颗粒罐设施，因此开发了一种新技术，其中通过将实验室制备的具有不同化学成分的颗粒放置在 Inconel 篮中，在硬化机中进行烧制。在目前的工作中，尝试通过开发 2 种不同的助焊剂颗粒，即低碱度（B2：CaO/SiO ₂ = 0.3) 球团和高碱度 (B2 = 0.9) 球团，并进一步研究了碱度对球团性能的影响，即冷压强度、孔隙率、溶胀指数、还原性指数以及软化和熔融温度。通过多次操作试验发现，将球团的碱度从 0.3 提高到 0.9 可以提高球团的强度、还原性以及软化和熔融特性。此外，观察到在低碱度和高碱度球团中添加 2% MgO 会降低球团的溶胀指数，这可能是由于球团中形成了高熔点熔渣。操作试验已导致生产的颗粒具有所需的机械强度、改善的溶胀性、
