The invention relates to a method for spraying a zirconia coating on steel surface flames in a reaction mode. The method is characterized by comprising the technological process that a steel plate is taken as a base plate, a thermal spraying pre-treatment method is used for rust removal, deoiling treatment and abrasive blasting to roughen the surface, preheating is carried out at the temperature of 150 DEG C+/- five DEG C, then, oxygen-aetylene flame spraying gun is used for spraying nickel alclad powder on the sand blasting surface of the base plate to be used as a priming coat, a ceramic stick spraying gun is used for spraying a composite ceramic stick transition layer comprising, by weight, 50 percent of titanium carbide and 50 percent of zirconia, the zirconia comprises 8 percent of yttrium oxide by weight, preheating is carried out at the temperature of 150 DEG C+/- five DEG C, the ceramic stick spraying gun is used for spraying self-propagating zirconia ceramic sticks with the 8 percent of yttrium oxide
