The invention discloses a cement kiln waste heat steam utilization system for autoclaved aerated concrete production. The cement kiln waste heat steam utilization system comprises a cement kiln waste heat boiler, a temperature and pressure reduction device, a waste heat temperature rise steam header, a temperature reduction steam header, four autoclaves, a vacuumizing steam header and a vacuum pump. The cement kiln waste heat boiler is used for providing superheated steam. One end of the temperature and pressure reducing device is connected with the cement kiln waste heat boiler through a first pipeline, and the temperature and pressure reducing device is used for conducting temperature and pressure reducing on the superheated steam, so that saturated steam is obtained. And the inlet end of the waste heat heating steam-distributing cylinder is connected with the other end of the temperature and pressure reducing device through a second pipeline. And the cooling steam-distributing cylinder is connected with fo
