The invention relates to a slag adhering method for a water-cooled wall electric furnace. The method comprises the following steps: in the electric furnace smelting process, components on the surfacepart of a refractory brick layer of an electric furnace lining react with liquid slag to form a high-melting-point substance, and under the cooling action of a water-cooled wall of the electric furnace lining, the formed high-melting-point substance is condensed on the surface part of the refractory brick layer to form a solid slag adhering layer. By means of the method, the furnace lining and thehigh-temperature slag can be isolated, the solid slag adhering layer is automatically thickened and thinned along with reduction and increase of the temperature of a molten pool in the smelting process, erosion of the slag to the refractory brick layer can be remarkably relieved or even eliminated, and therefore the service life of the furnace lining of the electric furnace is prolonged. 本发明涉及一种水冷壁电炉挂渣的方法，该方法包括如下步骤：在电炉冶炼过
