Micro carbon residue, commonly known as "MCR", is a laboratory test used to determine the amount of carbonaceous residue formed after petroleum materials are evaporated and pyrolyzed under certain conditions. This test is used to provide some indication of the coking propensity of the material. [1][

Traditional ferroalloy submerged arc furnaces generally use pre-baked carbon blocks and wide coarse joints to build the furnace lining, and adjust the primary current to control the depth of the electrode inserted into the furnace (that is, the load of the electric furnace). Take the main equipment of a company's 2*25.5MVA submerged arc furnace as an example. Its lining adopts semi-graphite charcoal brick fine-seam masonry technology, but the redness of the furnace bottom appeared three months after the furnace was opened. Through fine furnace anatomy and cause analysis, find out the solution to the problem.
