The invention discloses an ignition method for a sintering material surface, and relates to the technical field of sintering. The method comprises the following steps: uniformly distributing first fuel on a sintering material surface for ignition; the sintering surface material comprises the following preparation raw materials: an iron-containing raw material, a second fuel and a flux; the mass ratio of the first fuel to the second fuel is (1-2): (18-19); the sintering raw material is composed of a sintering material surface and a first fuel. First fuel is directly and uniformly distributed on the material surface of a sintering machine and enters an igniter to be directly ignited; therefore, the coal gas consumption is reduced, the sinter quality is improved, the return mine rate is reduced, and the service life of the ignition furnace is prolonged. 本发明公开了一种烧结料面的点火方法，涉及烧结技术领域；该方法包括以下步骤：将第一燃料均匀分布在烧结料面上点火；烧结面料包括以下的制备原料：含铁原料、第二燃料和熔剂；第一燃料和第二燃料的质量比为1～2：18～19；烧结原料由烧结料面和第一燃料组成。本发明将第一燃料直接均匀布在烧结机料面上，进入点火器直接点火；从而降低煤气用
