Influence of a processing machine unit on indoor thermal environment in a cold roll steel workshop

Studies the heat rejection mechanism of the unit by field measurement and theoretical analysis, and finds that the effect of heat rejection on environment temperature inside the workshop is invariable when hearth temperature varies around 800 ℃ and the influenced zone locates at each level of the work platform. Reasons that the temperature of a work platform is associated with outdoor temperature, and the vertical temperature gradient of a work platform is obvious. The simulating result by CFD software is coherence with the test and theory results. Points out that reasonable ventilation reconstruction can help improve the indoor thermal environment.
