The invention discloses a continuous casting functional protective material specially used for a high pressure oil well pipe, comprising the raw materials by weight percent: 46.0% of wollastonite, 5.0% of spodumene, 6.0% of sodium carbonate, 15.0% of fluorite, 4.0% of bauxite, 5.0% of manganese ore powder, 7.0% of graphite, 6.0% of carburant, 1.0% of carbon black, 3.0% of bentonite. The functionalprotective material produced by the research result can be used for casting steel 37Mn5 specially used for the high pressure oil well pipe on a Baosteel electric furnace 1# continuous casting machine; when the drawing speed is 2.5-3.2m/min, the slag consumption quantity is 0.45kg/T steel, and thickness of a liquid slag layer on the surface of molten steel is 8-12mm. The field test results prove that when in use, the functional protective material has good spreadability, heat preservation and melting property in a crystallizer; furthermore, the four sides inside the crystallizer are stable andeven in capacity of heat transmission, so that the requirement of high drawing speed can be met.
