Description

Technical Field

[0001] The invention belongs to the technical field of self-baking electrodes for submerged arc furnaces, and in particular relates to an unattended quantitative electrode paste adding device for submerged arc furnaces and a use method thereof. Background Art

[0002] Self-baking electrode is an electrometallurgical device that converts electric energy into thermal energy during the smelting process of the submerged arc furnace by the arc heat at the end of the baked electrode column and the resistance heat of the charge or slag, so that the alloy elements are reduced from the ore or oxide. In addition to the smelting of ferroalloy products, the submerged arc furnace also has an important task, that is, to bake the electrode. The quality of the electrode baking determines whether the smelting of the submerged arc furnace can operate normally. The self-baking electrode is mainly composed of an electrode shell, a conductive rib, and a baking electrode paste. The electrode paste is added to the electrode shell from the top of the electrode, and the electrode paste melts and sintered as the temperature rises. During the sintering process of the electrode paste, one of the important parameters that needs to be controlled is the baking area position, which is the area where the electrode paste changes from liquid to solid and the material begins to conduct electricity. An unreasonable baking area may cause hard break, soft break and paste flow of the electrode, and electrode accidents are the most important factors affecting normal production. In view of this situation, the important factors affecting the quality of electrode baking are stable paste column height and the way of adding electrode paste to prevent hanging paste accidents.

[0003] In the past, electrode paste was mostly added manually. Workers lifted the electrode paste to the electrode paste adding platform through material hoisting, used ton bags to hold the electrode paste and transported them to the opening above the electrode cylinder. They untied the bag and poured the electrode paste into the electrode cylinder. Due to the uncontrollable factors of manual paste adding, there might be too much or too little paste added, resulting in a large height difference of the paste column. Manual paste adding is prone to paste hanging accidents when the electrode paste is dumped instantly. Manual paste adding has a large workload. When the electrode cylinder is in working state, it is energized. If there is an operating error, electric shock accidents are likely to occur.

[0004] To this end, we provide an unattended quantitative electrode paste adding device and a method for using the device for an electric arc furnace to solve the above-mentioned problems. Summary of the invention

The unattended electrode paste dosing device and method of use for a submerged arc furnace according to claim 2, characterized in that: The outside of the mounting frame (405) is fixedly connected to a controller (411), and the plurality of pressure sensors (304), the electric push rod (406), the lifting motor (606d), the mechanical clamp (606g) and the rotating motor (602c) are all electrically connected to the controller (411).

10. A method for distributing material for a ferrosilicon ore furnace, characterized in that: The automatic rotary material distribution device and material distribution method for a ferrosilicon ore furnace according to any one of claims 1 to 9 specifically comprises the following steps: S1: The controller (411) controls the electric push rod (406) to retract, so that the material in the storage bin (200) falls into the quantitative barrel (301); then, when the pressure sensor (304) reaches a set value, the controller (411) controls the electric push rod (406) to extend, so that the upper gate plate (403) blocks the upper material control pipe (401), and at the same time, the lower material control pipe (402) is opened, so that the material falls into the inside of the feeding mechanism (500); S2: starting the mechanical clamp (606g) through the controller (411) to clamp the electrode barrel sealing cover, and then starting the lifting motor (606d) through the controller (411) to make the lifting screw (606f) rise, so as to open the electrode barrel sealing cover; S3: starting the rotating motor (602c) through the controller (411) to drive the central shaft (602a) to move the material distribution tube (605) to the top of the electrode cylinder after opening; S4: The material is conveyed into the hopper (604) by starting the conveying motor (503) to drive the stacking screw (502) to rotate, and then the material is fed into the ore-generating furnace through the material distribution pipe (605).
