The invention provides a slag adhesion resistant gunning refractory for a converter. The gunning refractory comprises the following components in percentage by weight: 35 to 45 percent of magnesia carbon refractory crushed brick recycled aggregate, 5 to 16 percent of magnesite clinker, 18 to 25 percent of fused magnesite, 5 to 8 percent of silicon carbide, 8 to 13 percent of graphite, 1 to 3 percent of alumina cement, 1 to 3 percent of silicon micro powder, 1 to 3 percent of alpha-Al2O3 micro powder, and 3 to 4 percent of sodium hexametahposphate. On the basis of the raw materials, 0.2 to 0.4percent of calcium lignosulfonate and 0.05 to 0.15 percent of polypropylene fiber are added; the magnesia carbon refractory crushed brick recycled aggregate has two granularities, namely comprises 30to 40 weight percent of aggregate with the granularity of 3 to 1 mm and 60 to 70 weight percent of aggregate with the granularity of 1 to 0.15mm; the granularity of the magnesite clinker is 1 to 0.15mm; the fused magnesite has two granularities, namely comprises 40 to 60 percent weight percent of fused magnesite with the granularity of 180 meshes and 40 to 60 weight percent of fused magnesite with the granularity of 325 meshes; and the granularity of the silicon carbide is 180 meshes.
