Abstract

One of the important parameters that indicates how strong a country’s industrial development can be seen from the steel industry progress. In Indonesia, PT Krakatau Steel, as strategic industry’s largest steelproducing state, had a role in efforts to improve the strength and power of the national industrial development. Therefore, PT Krakatau Steel continues to strive to improve the way national steel consumption, to increase its production capacity, through the development of supporting equipment. One of the most important supporting equipment is Sullair Screw Air Compressor Type which functions as the opening and closing furnace. Retrieval of data uses the data field conditions and specifications of equipment condition data compressor and completion to obtain the enthalpy of actual condition and the condition specification using the software of Computer Aided Thermodynamics Table 2 (CATT2). This research was conducted by taking a data compressor that is in Hot Strip Mill plant of PT. Krakatau Steel during operation. The average values of isentropic compressor efficiency 87.34%, with range 84.81- 89.48%. From the calculation results and discussion, it can be concluded that the compressor is used in Hot Strip Mill plant of PT. Krakatau Steel is still working fine even though the compressor is working continuously and only done 1 day deactivation of each month.
