An integrated refractory management system comprising: a cable module at least partially inserted into a refractory; a measurement module disposed outside the refractory and configured for measuring a current signal flowing through the cable module; an integrated management module configured for determining a condition of the refractory based on the current signal measured by the measurement module, displaying the condition of the refractory, and generating management information on the refractory; and a local terminal for receiving the management information from the integrated management module, characterized in that the cable module comprises one or more cables (110, 120 130) disposed inside the refractory, and each of the cables comprises: a metal wire having both ends coupled to the measurement module; and a space securing coating layer coated onto at least a portion of an outer surface of the metal wire and adapted for securing an expansion space for the metal wire by being melted upon increase in a temperature of the refractory, wherein the metal wire comprises a wire main body having a screw shape and a protrusion having a saw tooth shape and protruding from at least a portion of an outer surface of the wire main body, wherein the measurement module comprises: a sensor for measuring the current signal flowing through the cable module; and a data transmitter for transmitting the current signal measured by the sensor to the integrated management module, wherein the integrated management module comprises: a data reception unit for receiving the current signal sent from the data transmitter; a data analysis unit configured for analyzing the condition of the refractory by calculating the current signal sent from the data reception unit; a data output unit for displaying the condition of the refractory determined by the data analysis unit to monitor the condition of the refractory; and a management instruction unit configured for transmitting management information on the refractory to the local terminal, wherein the integrated management module further comprises a data storage for storing information related to the condition of the refractory, wherein the data analysis unit is further configured to determine management information of the refractory based on number and history of the refractory stored in the data storage, and wherein the data output unit is further configured to display the available stock and history of the refractory, and damage and breakage histories of the refractory. a cable module at least partially inserted into a refractory;
