The invention relates to an alkaline flow guiding sand used in a steel ladle, which belongs to the metallurgy technical field, and comprises the chemical compositions as follows (by weight percentage): passive limes account for 30 to 50 percent, calcites account for 5 to 15 percent, corundum accounts for 5 to 10 percent, calcined olivine sands account for 20 to 40 percent, and flaky graphite accounts for 1 to 5 percent; and all components are confected according to the proportions and then are mixed to form the alkaline flow guiding sand. The prepared alkaline flow guiding sand used in the steel ladle has the characteristics of high refractability, strong erosion-resistence, high ladle free opening rate, low cost, no environmental pollution, no damage to pouring box metallurgy environment, and convenient use.
