The invention relates to a magnesium silicate fiber blanket belonging to the technical field of fire-proof heat preservation and insulation materials. The magnesium silicate fiber blanket is characterized by comprising the following materials with oxides in percentage by weight: 40%-85% of SiO2, 3%-40% of MgO, 2%-30% of CaO, and the balance of one or the any combination of B2O3, Al2O3, Fe2O3, Na2O and K2O, wherein the total amount of the SiO2, the MgO and the CaO is more than or equal to 85%. The magnesium silicate fiber blanket is processed through the procedures of material melt, centrifugal thread throwing or blowing fiber forming, cotton collection, pinprick, heat treatment, cutting, and the like. The magnesium silicate fiber blanket has functions of non-inflammation, heat insulation,sound absorption and fire prevention and is a fire-resistant heat-preserving heat-insulating fire-proof material which is widely suitable for various heat engineering equipment and pipelines.
