The invention discloses a steel-making manufacturing execution management system based on visualized heat tracking. The system is used for connecting a production and marketing system and a workshop in-situ control and comprises a heat tracking platform, an application server, a database server and a client end. By means of the steel-making manufacturing execution management system, molten steel condition of each heat can be tracked, and the system has the advantages that information integration is high, data analysis ability is strong, process trace feedback is timely and clear and the like. The system can be a link for enterprise computer integrated manufacturing system (CIMS) information integration, and therefore a manufacturing business environment which is fast in response and flexible and refined can be provided for a user, the user is helped to lower cost, deliver goods on time, improve product quality and service quality.
