    摘要: AN IMPROVED QUENCHING OIL COMPOSITION COMPRISED OF A MAJOR PORTION OF A PETROLEUM OIL HAVING A VISCOSITY WITHIN THE RANGE OF ABOUT 40 TO ABOUT 300 SUS (SAYBOLT UNIVERSAL SECONDS) AT 100*F. AND A FLASH POINT IN EXCESS OF 250*F. AND ABOUT 2% TO ABOUT 15% BY WEIGHT OF A QUENCH OIL ADDITIVE, WHICH IS AN OIL SOLUBLE PETROLEUM RESIN PRODUCED FROM DISTILLATES OF CRAKED PETROLEUM STOCK HAVING A MELTING POINT OF AT LEAST 40*C. AND AN ANILINE POINT VALUE OF LESS THAN 50*C. (ASTM-D-6611-64). THE COMPOSITION DISCLOSED HEREIN HAS LED TO UNEXPECTEDLY GOOD QUENCHING OIL PROPERTIES AND IN PARTICULAR THE DISCLOSED QUENCH OIL COMPOSITION HAS UNEXPECTEDLY SUPERIOR HIGH TEMPERATURE STABILITY WHEN USED FOR PROLONGED PERIODS IN QUENCH OIL BATHS.
