A precision cutting tool for removing the excess wax wall of a pillar styled candle includes a ring configured to encircle the candle and a handle extending from the ring. The handle includes an extendible and retractable cutting element. The cutting element may be extended into the circle defined by the interior circumference of the ring in a gradual manner. The tool includes a recess for the cutting element to be retained when the tool is not in use. The interior of the handle includes a cutting element mover configured to cause linear movement of the cutting element into and partially out of the recess. When the mover is actuated in a direction that results in movement of the cutting element out of the recess, the cutting element extends partially into the candle located in the interior circle established by the ring. The candle or the tool may then be rotated to cause cutting into the candle wall until the excess wax wall can be removed.

The invention relates to the technical field of steelmaking technology, in particular to a method for utilizing CO2 to control a high-temperature fire point at a jet flow impact area of a coverter oxygen lance. The method is suitable for the steelmaking process of a 30-400 t converter. According to the converter converting process, based on the metallurgical reaction characteristic of a molten pool, the CO2 proportion in a blowing gas is dynamically controlled at different periods, by utilizing the high-temperature reaction characteristic of CO2, at the earlier stage of converting, thermal radiation of the fire point is reduced, at the metaphase of converting, stirring of the molten pool is intensified to accelerate transmission of substance and energy between the fire point and the moltenpool, and at the later period of converting, peroxidation of molten steel is prevented, the metal yield is increased, and the temperature distribution and fire point volume of the oxygen lance jet flow impact area are controlled during the converting process to further improve the smelting effect.
