High-temperature hot dipping method for producing steel strip hot dipped with zinc-base alloy

The invention relates to a high-temperature hot dipping method for producing a steel strip hot dipped with zinc-base alloy. When a steel strip is hot dipped with the zinc-base alloy, the working temperature of a dipping solution is controlled between 530 DEG C and 560 DEG C; and the operating power of an air knife blower is adjusted at most to a maximum value within a power interval which cannot initiate a metal flow line of a plate surface. In the invention, the temperature of the dipping solution is set as a value between 530 DEG C and 560 DEG C; at the same time, the operating power of theair knife blower is adjusted for a higher value as much as possible; because a temperature reducing space for the dipping solution of the plate surface is allowed to be greatly enlarged, the operating power of the air knife blower is greatly enhanced, the plating quantity is obviously reduced and zinc consumption is thoroughly reduced; and because the temperature region in which the dipping solution severely corrodes steel is avoided in the temperature range, a borne negative effect is much lower than the benefit retribution obtained due to zinc consumption reduction.
