The invention discloses a steel structure rust removing method, which comprises the following steps: (1) removing impurities on the surface of the steel structure: mechanically cleaning impurities on the steel structure base surface by using an electric steel wire grinding wheel; (2) rust removal on the surface of a steel structure: stably placing the steel structure into a derusting pool, and derusting in an immersion mode, wherein the steel structure is completely immersed in the liquid level of a derusting liquid in the derusting pool; (3) after the derusting of the derusting liquid is finished, washing the surface of the metal product by clear water; (4) after the rinsing process is finished, drying the steel structure in drying equipment, and performing an anticorrosion process on the steel structure after the drying is finished; (5) and carrying out anticorrosive treatment on the dried steel structure by adopting an electric arc spraying anticorrosive coating mode. The process is simple, and the rust removing effect is good; the derusting waste liquid can be poured into a sewer, is green and environment-friendly, and can be degraded by microorganisms. |
