The examples described herein provide methods and equipment for an anti-oxidation spraying on a steel billet. In some examples, when the billet at the temperature of 400&#xb0; C.-1000&#xb0; C. enters the predetermined spraying region, a plurality of anti-oxidation spraying devices are used to perform an anti-oxidation spray on the billet in two or more directions, thereby forming directly an anti-oxidation coating on the steel billet at 400&#xb0; C.-1000&#xb0; C. By using the example method and equipment described herein, on-line spraying of anti-oxidation coating on the steel billet can be performed under high-temperature condition, thereby reducing an oxidation burning loss rate of the steel billet.

The present disclosure relates to an antioxidation coating for steel. In one example, the coating is produced by mixing magnesian mineral, layered silicate, metallurgical solid waste, aluminum powder, organic thickener and inorganic binder including the components of AlO, SiO, MgO, CaO, FeOor the like with water, and the final coating density is adjusted to 1,100&#x2dc;1,500 kg/mby adding water.
