The invention relates to ultrasonic detection equipment special for a quenching nozzle and a quenching nozzle detection method. The ultrasonic detection equipment special for the quenching nozzle comprises a detection probe and a rubber block which is arranged between the detection probe and the quenching nozzle in a contacting mode and serves as a coupling medium for use. When testing is conducted on the quenching nozzle, the problems that due to the fact that a fluid coupling medium permeates the interior of the quenching nozzle, electrical characteristics of the quenching nozzle are affected, and the fluid coupling medium is difficult to clean do not exist, acoustic impedance of rubber is closer with that of the quenching nozzle compared with acoustic impedance of air, and the sensitivity of testing is high.
