The inherent properties of raw rubber material necessitate preheating before the mixing process, with the proper temperature control in rubber drying room directly determining the final quality of raw rubber. The heat load per square meter in rubber drying room is also the highest part within the tire processing production line, making the selection of appropriate and efficient heating systems crucial for both wire product quality and product line operational costs. This study integrates heat load, steam mass flow rate, and other operational parameters of a wall-mounted radiator heating system and a steel floor radiant heating system implemented in the raw rubber rubber drying room of a European tire manufacturing plant under winter conditions. From a theoretical perspective, the research analyzes and establishes heat balance equations and temperature gradient models. Factory test measures the indoor temperature during the whole process of rubber drying, also comparing horizontal temperature differentials in rubber drying room and vertical temperature gradient between the two systems provide empirical evidence for heating system selection in rubber drying rooms.
