Abstract

A method for removing a coating from a refractory armor is disclosed. The coating removal method may include the step of detecting the amount of wear on the refractory armor by means of a detector; the step of removing the coating on the upper side surface of the inner circumferential surface of the refractory armor based on the amount of wear on the refractory armor by means of a first blade parallel to a rotation axis; and the step of removing the coating on the lower side surface of the inner circumferential surface of the refractory armor based on the amount of wear on the refractory armor by means of a second blade inclined toward the rotation axis as it extends toward one side. A coating removal system for a refractory armor capable of executing the above method for removing the coating of the refractory armor is further disclosed. Additionally, a refractory armor in which the coating on the inner surface has been removed by the coating removal system is further disclosed.

Description

System and Method for Removing Coating from Saggar The present invention relates to a coating control system and method for a refractory armor, and more specifically, to a coating control system and method for a refractory armor that controls the amount of coating removed from the refractory armor based on the amount of wear of the refractory armor. The cathode material plays a crucial role in determining the charging speed and lifespan of a battery. Typically, graphite is primarily used as the cathode material; however, due to stability issues such as expansion during use, silicon-based cathodes with added silicon are being utilized. These silicon-based cathodes are broadly classified into three types: silicon alloy cathodes, silicon oxide cathodes, and silicon-carbon composite cathodes. In silicon-based anode materials, some particles may separate due to cracks caused by the volume expansion of silicon, leading to the formation of a Solid Electrolyte Interphase (SEI) layer on the surface. Since this SEI layer can cause adverse effects by blocking lithium entry pathways, technologies such as making silicon particles smaller or applying a carbon layer nanocoating are being developed. Generally, coating with natural graphite is performed by heat-treating natural graphite together with pitch. More specifically, a carbon layer coating of natural graphite is performed by placing natural graphite together with pitch in a saggar and heating it to a high temperature. When a natural graphite coating is applied, a carbon-based coating layer accumulates on the inner surface of the refractory, and this layer can reduce the internal volume of the refractory, thereby decreasing productivity. To prevent productivity loss caused by the coating layer, it must be removed mechanically or by combustion. In contrast, as heat treatment or firing proceeds, the outer surface of the refractory, particularly the outer edges, oxidizes and wears down. If this wear continues, the thickness of the refractory wall decreases, and in severe cases, holes may be formed in the wall.
