The Influence of Construction Methods on the Service Life of Dry Ramming Mix for Electric Furnace Hearths

by

Currently, the working linings of high-power and ultra-high-power electric arc furnaces are generally constructed using dry-type magnesia ramming mixes. These mixes are formulated with a multi-stage particle size distribution, utilizing iron-rich, calcium-rich synthetic magnesia and fused magnesia as aggregates, along with synthetic and fused magnesia fines (with a maximum particle size of 5–6 mm). Dicalcium … Read more
