The invention relates to a high-strength refractory matter drilling method. The high-strength refractory matter drilling method is characterized in that a round iron plate with a hole in the center is put on the crucible bottom of a to-be-drilled crucible for drilling and mark locating; the fixed end of a hole opener is fixed to a bench drilling machine, the to-be-drilled crucible is inversely arranged on the bench face, the position of the crucible bottom is adjusted, and the drilling machine is started; during operation, the hole opener is controlled to move downwards at a constant speed, and when a saw tooth on the lower portion of a hole opening column is aligned to a hole mark of the crucible bottom, drilling is started; a proper amount of water is sprayed for cooling while drilling is achieved; after drilling is completed, a switch of the drilling machine is turned off, the hole opener is taken down, the stand column end of a hole chamfering device penetrates a hole of the crucible bottom to be fixed to the bench drilling machine, the hole chamfering mold end is located below the crucible bottom, the drilling machine is started, and the hole of the crucible bottom is subjected to hole chamfering treatment; and when a hole chamfering device moves upwards to the position, 5-8 mm away from the upper end face of the hole chamfering mold, of the upper end face of the hole of the crucible bottom, hole chamfering is stopped, the drilling machine is shut down, the hole chamfering device is taken down, and hole chamfering is completed. According to the high-strength refractory matter drilling method, a high-strength smooth and clean hole wall can be obtained, and connection of two fire-resistance devices is facilitated.
