Abstract

The invention discloses a device and method for drilling a tap hole on a submerged-arc furnace through oriented plasma. By drilling a through hole in the center of a carbon rod, introducing an inert gas and connecting the carbon rod to a power supply to generate plasma arc, a tap hole can be drilled on the submerged-arc furnace through the oriented plasma arc; and the device and method have the advantages of high temperature, easy control of the hole shape, high efficiency, saving of electric energy, and short time in drilling the tap hole. According to the device and the method disclosed by the invention, the difficult problems, such as long time required in drilling the tap hole during furnace tapping, low efficiency, high consumption of electric energy and high labor intensity which obsess the smelting industry adopting the submerged-arc furnace for a long time are solved; and the efficiency in drilling the tap hole is improved, the time for drilling the tap hole is shortened, the consumption of electric energy for drilling the tap hole is reduced, and the labor intensity of workers is reduced. Long-range automatic operation of tap-hole drilling during furnace tapping of the submerged-arc furnace is realized.

Description

technical field [0001] The invention relates to a device and method for opening holes in a directional plasma submerged arc furnace. Background technique [0002] Submerged arc furnace is a kind of electric arc furnace series. The smelted products are ferrosilicon, silicon-manganese alloy, ferroalloy, yellow phosphorus, calcium carbide, corundum, etc. The core theory of its smelting is: form directional high-temperature ion flow through ionized air- Electric arc, which converts electrical energy into heat energy, provides a sufficiently high temperature field for the reduction reaction. [0003] During the smelting process, with the gradual progress of the smelting procedures, the liquid level (or slag level) of the molten pool of furnace bottom products continues to rise. When the products in the furnace accumulate to a certain amount, it is necessary to open a hole in the direction parallel to the furnace bottom plane. (that is, open the furnace hole) to make the product ...
