The invention discloses a continuous casting method capable of reducing an inclusion rate of hot rolled steel coils. The continuous casting method comprises the following steps: firstly, increasing percentage by weight of molten steel to 25-32% while starting casting a first tank of tundish, adding 0.4-0.5kg/t of lime into the tundish, starting adding a covering agent when weight of molten steel in the tundish is 75-80%, checking whether the tundish has foreign matters or not before starting casting, and regulating argon gas flow when an argon gas system has no gas leakage: regulating argon gas flow between plates to be 4-6m<3>/h 0.5h before starting casting; while starting casting, controlling argon gas flow of a stopper rod to be 1.8-2.2m<3>/h, closing argon gas in an upper nozzle and argon gas between the plates; and in a casting process, controlling maximal argon gas flow of the stopper rod not exceed 5m<3>/h, and controlling maximal argon gas flow of the upper nozzle not exceed 10m<3>/h. When depth of a submersed nozzle changes in the continuous casting process, electromagnetic brake current intensity of a crystallizer is automatically regulated. According to the continuous casting method, inclusion in steel can be greatly reduced, and casting blank quality can be improved, so that an inclusion blocking rate of hot rolled products is reduced to be lower than 2%.
