Synopsis : Evaluation methods of heat streak resistance and sheet surface cleaning property of cold rolling oil were established. The lubricity was evaluated by scoring limit load using the modified Timken tester and four-ball tester. Surface cleaning property was quantitatively evaluated by the quantity of carbon on the surface of the test piece after annealing. Through these methods, it was possible to develop high lubricity rolling oil with performance to increase 10 to 20% rolling speed and to decrease 15% oil consumption compared with those of the conventional rolling oil. The new surface clean rolling oil has a good surface cleaning property and lubricity that can be used in rolling of the steel sheet with 0.4mm thickness. |
