Embodiment Construction

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] figure 1 It is an exploded perspective view of an injection nozzle introducing device for a smelting furnace according to an embodiment of the present invention, figure 2 yes figure 1 side view. refer to figure 1 and figure 2 , The injection nozzle introducing device for a smelting furnace comprises a main body (100), a driving part (200), a pushing and moving part (300), and a driving control part (400).

[0019] The main body (100) arranges the injection nozzle (20) and the shaft portion of the pushing and moving part (300) that moves linearly in accordance with the operation of the driving part (200) to be described later so that they are arranged on the same axis as each other. In the supported state, it is possible to guide by sliding and moving. That is, the main body (100) supports the shaft portion of the injection...

Abstract

The present invention provides an injection nozzle introduction device for a smelting furnace, the device comprising: a body coupled and arranged on one side of a smelting furnace to support an injection nozzle such that the same can slide in a horizontal state; a driving unit coupled and installed on the body to generate a rotating driving force; a push movement unit which is connected to the driving unit while being installed on the body, and which receives a rotating driving force transferred from the driving unit, converts the same into a straight movement, and then causes the injection nozzle to be pushed towards the interior of the smelting furnace; and a driving control unit for grasping a horizontal movement position resulting from the straight movement of the push movement unit and then controlling operation of the driving unit. Such an injection nozzle introduction device for a smelting furnace is configured such that the driving control unit controls the driving unit to operate at every predetermined time, and the push movement unit automatically introduces the injection nozzle into the smelting furnace periodically, thereby facilitating the process of introducing the injection nozzle and preventing danger of any accidents.

Description

technical field [0001] The present invention relates to an injection nozzle introduction device for a smelting furnace, and more specifically, to an injection nozzle for a smelting furnace that periodically introduces an injection nozzle that supplies fuel to the interior of the smelting furnace to improve the combustion efficiency of ore Bring in the device. Background technique [0002] Generally, a smelting furnace for smelting iron and steel or non-ferrous metals is equipped with injection nozzles to supply liquid fuel such as heavy oil and delayed gas such as oxygen or oxygen-enriched air to high-temperature granular ore in the smelting furnace, and the fuel supplied by the injection nozzles Combustion energy to improve the heating, melting and reduction efficiency of the ore in the smelting furnace. [0003] The end of the injection nozzle is disposed inside the smelting furnace, and if it is used for a certain period of time inside the smelting furnace in a high temp...
