Steel ladle wire feeding auxiliary device and steel ladle wire feeding method

Abstract

The invention provides a steel ladle wire feeding auxiliary device and a steel ladle wire feeding method. The steel ladle wire feeding auxiliary device comprises a steel ladle and a wire-feeder arranged on a working platform. A metal wire lead-out tube of the wire-feeder is connected with the steel ladle wire feeding auxiliary device which is arranged in an ascending and descending manner, metal wires are delivered into the steel ladle wire feeding auxiliary device by the metal wire lead-out tube, and then the metal wires are directly injected into the liquid steel in the steel ladle by the steel ladle wire feeding auxiliary device. The working platform is provided with a ventilating and dedusting device with a vacuumizing unit, and the ventilating and dedusting device is connected with the inner portion of the steel ladle wire feeding auxiliary device and is in pipeline communication with the steel ladle wire feeding auxiliary device. By means of the steel ladle wire feeding auxiliary device and the steel ladle wire feeding method, the metal wires are directly fed into the liquid steel, the phenomena that the wires are melt before entering into the liquid steel, and the wires cannot enter the liquid steel due to the fact that steel slag is too thick are avoided, and the wire yield rate is increased; gases and smoke dust are discharged into the ventilating and dedusting device, and the environmental pollution is reduced; and the metallurgical reaction conditions of the liquid steel in the steel ladle are changed by the vacuumizing unit, part of the metallurgical reaction velocity is increased, the oxidation loss of useful elements is prevented, and the alloy yield rate is increased.

Description

technical field [0001] The invention relates to the refining equipment outside the steelmaking furnace and the technical field in the iron and steel production industry, in particular to a ladle wire feeding auxiliary device and a ladle wire feeding method for directly feeding wire into molten steel, which can effectively improve wire feeding yield. yield and reduce environmental pollution. Background technique [0002] Modern steelmaking technology smelts molten iron into molten steel through a series of operations and transports it to the continuous casting machine. The molten steel passes through the continuous casting machine to produce qualified billets. Extra-furnace refining is an important part of the steelmaking process. It acts as a buffer between the continuous casting machine and the primary furnace (converter or electric furnace), and provides molten steel with suitable temperature, composition and time to the continuous casting machine. [0003] In the above-m...
