Slide pedestal smelting process

Abstract

The invention discloses a slide pedestal smelting process. The slide pedestal smelting process includes steps of preparing hearth furnace burden comprising fire clay, quartz sand, titanium alloy and water; filling the hearth furnace burden into a medium-frequency quick smelting furnace to produce a hearth furnace and reserving a tuyere on the hearth furnace; regulating the internal temperature of the medium-frequency quick smelting furnace to be 750-800 DEG C so as to dry the hearth furnace; making a fire in the medium-frequency quick smelting furnace to enable the internal temperature of the medium-frequency quick smelting furnace to be 950-1000 DEG C; charging the hearth furnace with materials including coke, pig iron, wrought iron, high-manganese steel, silicon and iron; increasing the internal temperature of the medium-frequency quick smelting furnace to be 1800-2200 DEG C and then smelting the materials in the medium-frequency quick smelting furnace; opening the medium-frequency quick smelting furnace to discharge molten iron under the temperature ranging from 1800 DEG C to 2200 DEG C; and finally pouring the molten iron into a mold cavity by a bull ladle so as to realize casting. The slide pedestal smelting process is simple, is high in production efficiency, has no affection to alloy compositions, and can be used for smelting alloy with high smelting point.

Description

Technical field: [0001] The invention relates to a smelting process suitable for a slide base of a gantry milling machine. Background technique: [0002] At present, the smelting of sliding bases is carried out by ceramic refractory materials and graphite crucible alloy induction melting furnaces. During the melting process of ceramic refractory materials and graphite crucible alloy induction melting furnaces, alloy elements are easy to react with ceramic and graphite crucible materials, resulting in alloy Contaminate and affect the chemical composition of the alloy; the ceramic crucible material itself or the reaction product of the alloy element and the graphite crucible easily enter the alloy and become foreign inclusions, and, due to the influence of the temperature resistance and strength of the ceramic refractory material, it is difficult to smelt with a melting point higher than High melting point alloys above 2000°C.
