A smelting short net

Abstract

A smelting short net, comprising a first main row, a second main row, a third main row and a first branch row, a second branch row correspondingly connected to the first main row, the second main row, and the third main row and the third branch row, the first branch row, the second branch row and the third branch row are all provided with electrode rods, the first main row, the second main row and the third main row are arranged in parallel with each other, and the second main row The row is located below the first main row and the third main row and the distance between the first main row, the second main row and the third main row is equal; the first branch row, the second branch row and the third branch row respectively pass through The electrode pushing device is connected with the electrode rod; the electrode pushing device includes a linear propulsion mechanism and an electrode rod fixing device arranged on the linear propulsion mechanism, the electrode rod fixing device is made of conductive material, and a There is insulation.

Description

technical field [0001] The invention relates to the field of ore smelting, in particular to a smelting short net. Background technique [0002] Pearl sand has been recognized by the foundry industry as a precision casting material, and its usage is gradually increasing. The principle is to connect an electrode rod through three main rows through high-voltage three-phase electricity, and then generate an arc through the electrode rods on the three main rows approaching each other. Heat is released, and the production of orb sand is carried out by the heat generated. [0003] Electricity is the main cost in the production process of pearl sand. In the prior art, three main rows are arranged in parallel on the same plane. Due to the large current passing through the main rows, "enhanced phase" and "weakened phase" are generated between the three main rows. Lead to power transfer; the positions of the three electrode rods are relatively fixed, and the current in the three main ...

Problems solved by technology

[0003] Electricity is the main cost in the production process of pearl sand. In the prior art, the three main rows are arranged in parallel on the same plane. Due to the large current passing through the main rows, "enhanced phase" and "weakened phase" are generated between the three main rows. Lead to power transfer; the positions of the three electrode rods are relatively fixed, and the current in the three main rows will change after a period of use. When the current is too high, it will cause waste of electric energy. When the current is too low, the arc heat generated by the three electrode rods Low temperature, not up to the temperature required by the process, short grid structure and unreasonable space layout, often resulting in low power factor, large power consumption, low transformer utilization efficiency, and high production costs
