The invention discloses a two-channel continuous casting flame cutting torch. The two-channel continuous casting flame cutting torch comprises a cutting torch body, a cutting torch gun head, a high-pressure oxygen pipeline, cooling water pipelines, two sets of fuel gas medium pipelines and two sets of combustion-supporting gas pipelines. The two sets of fuel gas medium pipelines and the two sets of combustion-supporting gas pipelines are connected to corresponding independent mixing chambers respectively, and the two mixing chambers are connected with corresponding hole channels in a continuous casting nozzle respectively. After the high-pressure oxygen pipeline, the two sets of fuel gas medium pipelines, the two sets of combustion-supporting gas pipelines and the cutting torch gun head are integrally welded, the high-pressure oxygen pipeline, the two sets of fuel gas medium pipelines, the two sets of combustion-supporting gas pipelines, the cutting torch gun head and the cooling water pipelines are inserted into the cutting torch body jointly and welded to the two ends of the cutting torch body, and a sealed water cooling cavity is formed in the cutting torch body. The two-channel continuous casting flame cutting torch is simple and compact in structure and easy and convenient to control, flowing and stopping of fuel gas mediums in the two pipelines can be automatically controlled according to control system instructions, just by adding one fuel gas medium pipeline and one combustion-supporting gas pipeline on an existing continuous casting cutting device, and the purposes of energy saving and consumption reducing are achieved.
