Arc burner (electricaltapper) refers to the production of ferroalloys submerged arc reduction furnace using the arc burn opening iron outlet of the special equipment, also known as the arc opening machine. According to the size of the furnace capacity, the number of iron outlet, as well as the furnace body rotation or not, burn through a variety of types of burner, in order to adapt to the furnace furnace mouth operation. The simplest type is a graphite or carbon electrode placed horizontally in front of the iron outlet and connected to the burn-through bus. Burning through the mouth of the iron bar resting on it, you can use carbon brick masonry and the formation of an arc between the mouth of the iron, to achieve the purpose of burning through. This way of iron bar consumption, and the product iron content will also be increased, mostly used in small and medium-sized electric furnace occasions. For large-scale electric furnace and furnace body rotating type electric furnace, usually use the movable electric burn through, through the installation in front of the iron outlet above the hanging rail, and with the help of straight line or according to the arc of the moving trolley, so that the burn through the iron outlet near the desired position, when not in use, it will be pushed to the side. The burner can be used to burn through the spout directly with a graphite electrode rod or indirectly with an iron bar resting on the graphite electrode rod.

Advantages of short network reactive power compensation for mineral heaters: 1. Reduces transformer and short network losses and improves transformer active output. 2. Reduce the high harmonic value, effectively improve the power factor, to avoid the power
supply department's scheduling fines 3. Stabilizing the reactive power consumption of the system, more uniform combustion of the furnace charge, more stable alloy composition, and greatly improving the rate of product quality.
The Role of Mineral Heat Furnace Short Net Systems:
1. The short network in the mineral heating furnace is the main power supply equipment of the secondary circuit between the transformer and electrode of the furnace, the resistance and reactance of the short network will have a great impact on the mineral heating furnace, the reactance of the short network to a large extent to determine the efficiency of the mineral heating furnace, power factor and energy consumption. 2. Due to the unevenness of the conductor of the short network, so that the current flowing through the conductor is not uniform, resulting in a three-phase short network of mineral furnace "static phase" and "storm phase" power transfer phenomenon. Therefore, for different types of mineral furnace furnace, choose a different short network structure, a reasonable reactive power compensation, is an important part of the energy saving and efficiency of the mineral furnace.

Short net system: Mineral heat furnace short network is the high current line from the secondary side of the transformer to the electrode. Generally refers exclusively to the hard busbar part, divided into two categories of copper tube type and copper row type.Now most of the tube type short network, the advantages of the tube type short network are: can be short network and copper tile series into a water circuit, cooling water circuit is: short network → water-cooled cable → conductive copper tube → copper tile → conductive copper tube → water-cooled cable → short network → phase-regulating water-cooled cable → transformer tubular outlet pipe → phase-regulating water-cooled cable → short network, and then discharged. Because the short network can be cooled by water, the current density of the short network and water-cooled cable is increased by several times, and the weight of the short network is reduced a lot.
Components of the short network: The complete shortnet consists of the following parts: 1) Compensator: connects the low voltage end of the furnace transformer to the fixed part of the shortnet. (2) Busbar: the longest fixed part of the shortnet, which can be a rectangular copper row or a water-cooled copper tube. (3) Fixed connector: Used to connect the water-cooled flexible cables from the busbar to the shortnet and to transmit the current. 4) Water-cooled flexible cable: Used to transfer the current from the fixed coupling block to the copper electrode gripper.
