The invention relates to the field of metal plate strip heat treatment, in particular to a metal plate strip temperature measuring device for a roller type quenching machine and a temperature controlmethod. The metal plate strip temperature measuring device comprises a protection mechanism, a waterproof box, a purging mechanism and a temperature measuring mechanism; and the metal plate strip temperature measuring device is installed between transition roller ways (9) behind a rolling quenching section (7) and in front of a normal-pressure quenching section (8) of the roller type quenching machine, and temperature measurement can be completed without making contact with a metal plate strip. The temperature control method of the metal plate strip temperature measuring device comprises a speed temperature control method and a water volume temperature control method; and the temperature of the metal plate strip is controlled by changing the running speed of the metal plate strip and the water spraying amount of a
