The invention relates to a manufacturing method of ultra-temperature pitch using coal pitch as a raw material, comprising the following steps of: a, evenly heating a medium-temperature liquid coal pitch raw material insulated at the temperature of 180 DEG C at the speed of 13-15 DEG C per hour and mixing by starting a mixing device when the temperature raises to 250 DEG C in a kettle; b, carryingout oxidation reaction when the temperature raises to 320 DEG C in the kettle and carrying out reduced pressure distillation after the distillate quantity is stable; c, when the temperature raises to375+ / -5 DEG C, stopping raising the temperature, maintaining the temperature, sampling, analyzing softening points until the softening points satisfy product requirements, wherein the total oxidationreaction time reaches 5-10 hours; stopping heating, introducing air and evacuating, discharging, and cooling to the normal temperature. The manufacturing method of ultra-temperature pitch can not cause local overheating concentration, leads aggregated molecules to have even distribution and stable quality, can produce high-temperature and ultra-temperature pitch according to requirements, shortens the production time, prolongs the service life of a device, and greatly improves the product quality.
