PURPOSE: A uniformed heating type burner is provided which is capable of preventing alloying deviation generated on the surface of the strip by uniformly distributing a flame ejected on a strip along a full width of the strip, thereby preventing quality defects due to generation of the alloying deviation on the surface of the strip. CONSTITUTION: In a burner which directly heating the surface of a strip(S) that is zinc coated in a heat protecting truck(122) after coating zinc on the surface of the strip(S) during galvanizing, the uniformed heating type burner is characterized in that a plural casings(10) which are extended in a width direction of the strip(S) and oppositely arranged each other are installed at the inner side of a housing(122a) of the heat protecting truck(122), a fuel gas and air are supplied into the casings(10), stirring means(20) capable of uniformly mixing the fuel and air are installed inside the casings(10), and a knife type nozzle is formed at the front part of the casing(10) so that a curtain type flame is ejected into the side of the strip(S).
