Pengaruh Temperatur Pasta terhadap Mutu Anoda Di PT. Indonesia Asahan Aluminium

Abstract

In the process of processing raw materials into anode common problems that can harm the company. Problems among the temperature pasta anode at the time of mixing will affect the level of quality anoda at the time used in the oven anoda reduction. Ko-kneader function as a tool to mix the raw materials (coke, butt, pitch, green and scrap). In the process this raw material is mixed gradually. The first stage coke and butt first heated with the temperature 165o C in order to achieve optimum temperature during the mixing process, this is done in the preheater and then flowed to the co-kneader. The second green scraps and pitch directly entered into the co-kneader so that the pasta will be reduced. Which is the main problem is how to handle or attempt to use a temperature that is stable and achieve the desired quality anoda company. The way to maintain the temperature at the time of mixing pasta remain stable with the way each time marlotherm hot oil stream to the wall - a wall-ko kneader until the paste is ready for printing.
