##### Ferroalloy furnace: a way to prevent carbon furnace lining failure

Carbon lining is the material of choice for most ferroalloy linings. However, as the capacity of submerged arc furnaces continues to increase, the early failure of the lining is a very prominent problem. This technology uses a relatively simple method to solve the problem that has long plagued the i
