In iron making dialogue, a salamander is referred to all liquid and solidified materials in the hearth of a blast furnace which cannot be removed through the taphole. Taphole locations are designed in a way that a pool or sump of liquid hot metal remains in the bottom of the hearth. The resulting salamander has multi purposes. Primarily it provides a buffer to retard bottom refractory wear, acts as a thermal reserve to smooth process swings, and can aid in the control of hearth wall wear through preferential liquid flow patterns in the hearth bottom. Over the course of a campaign, the hearth bottom wears and the final salamander size prior to reline is normally substantially larger than the original design.
