Preparation method of ferrosilicon nitride porous ceramic sliding plate
The invention belongs to the field of inorganic nonmetallic materials, and relates to a preparation method of a sliding plate for a steel-making ladle sliding gate mechanism, in particular to a preparation method of a ferrosilicon nitride porous ceramic sliding plate. The ferrosilicon nitride porous ceramic sliding plate disclosed by the invention is characterized in that the inner core of the sliding plate is prepared by directly cutting an original ferrosilicon nitride blank body; and the periphery of the sliding plate is poured and formed by adopting an unshaped fire-resistant material. The ferrosilicon nitride sliding plate is a carbon-free sliding plate; therefore, molten steel carburetion of the sliding plate generated in the use process can be avoided; the production requirements of clean steel in the future can be satisfied; the chrome-free property of the sliding plate is realized; pollution of chrome to the environment is avoided; the processing technology is simple; sintering and heat treatment are unnecessary; raw materials, energy, equipment, manpower and time are saved greatly; the cost is low; the preparation method is applied to large-scale industrial popularization; the porous ceramic material is applied in the sliding plate, so that the basic performances of the sliding plate are ensured, and simultaneously, the thermal shock resistance of the sliding plate is increased; the porous ceramic is applied in the sliding plate disclosed by the invention for the first time, so that a new field is created for developing the sliding plate material, and the development direction shows a promising future.
