The invention relates to a production method of a hollow heat preserving feeder head with a separation plate. The method comprises the following steps: (1) producing a work layer material; (2) producing a heat-preserving layer material; (3) molding the feeder head; and (4) drying. Compared with the prior art, the production method has the beneficial effects (1) the working layer and the heat preserving layer are made of different raw materials, the working layer is resistant to washout of high-temperature liquid steel and resistant to erosion, and the heat preserving layer has a cold retardant and heat preserving effect; the strength of the working layer and the strength of the heat preserving layer are higher under the same thickness, and the high temperature resistance is better; (2) the heat conduction efficiency can be remarkably reduced by adopting the separation plate, and the heat preserving performance of the side wall of the heat preserving feeder head can be greatly improved; (3) multiple layers of independent and completely-closed hollow chambers are produced by adopting a mold and a solid gasification module, so that the sealing performance and completeness are good, and the heat insulation, heat preserving and high temperature resisting performance requirements of the feeder head can be met; (4) parts on two sides of the separation plate are respectively provided with a lengthened structure, so that the displacement in the compounding process can be prevented, and the separation plate is more firmly connected with a composite heat insulation layer; (5) the process flow is simple, and the operation is easy.
