Torpedo tank car deslagging material and preparation method thereof

The invention discloses a torpedo tank car deslagging material and a preparation method thereof. The torpedo tank car deslagging material comprises the following component by weight: 17-23 parts of B2O3; 10-14 parts of CaO; 2-3 parts of SiO2; 1-3 parts of Na2O; 7-11 parts of CaF2: and 1-3 parts of a binder. The preparation method includes: mixing the B2O3, the CaO, the SiO2, the Na2O, the CaF2 and the binder, then adding a proper amount of water and stirring them evenly to make pellets with a diameter of 10-20mm, then drying the pellets and preserving them. The torpedo tank car deslagging material provided in the invention ensures that slag and salamanders in the tank can be continuously and effectively dissolved from the bottom of the torpedo tank car to the top. Meanwhile, the torpedo tank car deslagging material also has the characteristics of difficult agglomeration and easy skimming from the torpedo tank car.
