Resin in taphole clay provides good extrudability and strength at low temperatures. However, it also contains volatile matter that is lost on heating. The blast furnace taphole is subject to a large thermal gradient, leading to variation in the bonding and structure of the clay along the taphole’s length. This has a critical effect on properties. Effects of this variation in properties on furnace operations are not well understood. A simple laboratory test was devised to simulate the thermal gradient, and assess its effects on taphole clays. Thermogravimetric tests were also conducted at different heating rates. Results of experiments are …
