Abstract
The invention relates to resin sand specially used for probe cores and a high-efficient structural sublance dual probe made of the resin sand. The resin sand specially used for the probe cores improves the whole temperature tolerance property and the intensity of the resin sand by adding a proper amount of high-temperature sand in the quartz sand with low heat resistance. The probe core made of the resin sand can be used in the high-temperature and high-pressure working condition of a converter and also has appropriate brittleness; therefore, when a probe falls into a platform bucket which is lower than 20 meters, a coupon can be crashed automatically and the coupon can be sent to carry out a spectroscopic analysis directly without needing workers to beat by a hammer, thereby relieving the labor intensity of the workers, shortening detection time and increasing steel-making speed. The high-efficient structural sublance dual probe directly moulds a die cavity to form a sample box containing cavity, a fixed carbon chamber and a molten steel flow passage in the probe cores made of the resin sand. The fixed carbon chamber has no metal pieces and the resin sand has good adiathermancy, thereby slowing down the freezing rate of iron and steel solution in the fixed carbon chamber and increasing the precision of the fixed carbon. According to the actual analysis and comparison, the precision of the fixed carbon can be steadily improved to be above the standard grade; simultaneously, the sublance dual probe saves a plurality of spare parts, which leads the whole manufacturing cost to be reduced by more than 30 percent.
