Abstract
The utility model discloses a graphitized furnace connected in series with a silicon rectifying transformer, which comprises a graphitized furnace. A transformer is connected with the graphitized furnace through a switch; and a conductive board on a conductive electrode is connected with a power transmission bus on the transformer. The graphitized furnace is characterized in that a rectifying device comprising a plurality of silicon rectifying combined elements is arranged on the transformer; one end of each silicon rectifying combined element is connected with the outlet wire end of the transformer and the other end thereof is connected with the power transmission bus. The rectifying device formed by the silicon rectifying combined elements is arranged on the transformer, so that after rectifying of the rectifying device, the transformer can provide high current and stable low voltage for the graphitized furnace; and 3000 to 4000 kwh of electricity is consumed for each ton of product,thereby greatly saving energy consumption, improving product quality and output, reducing manufacturing cost and increasing enterprise competitiveness.
Description
Technical field
The utility model belongs to the graphite production technical field, particularly a kind of silicon rectifying transformer cascade graphitizing furnaces.
Background technology
At present, the graphitizing furnace of China's carbon industry production greying goods has two kinds of type of furnaces: a kind of is to adopt following 3340KVA of 20000KVA and the 6680KVA specification stove acheson furnace of transformer, carbonaceous product power consumption 4500-5500 degree per ton when this stove is produced Graphite Electrodes, every stove product batch is the 60-110 ton, the greatest problem that exists is that stove, transformer specification model are too small, make little, the spread of voltage of electric current, thereby cause yield poorly, consume energy height, poor product quality; Another kind is the inner string graphitization stove of promoting in recent years, power consumption 3600-3800 degree per ton when this stove is produced Graphite Electrodes, but compare about Graphite Electrodes brownout 800-1800 degree per ton with acheson furnace, but the greatest drawback of this stove is to yield poorly, every stove can only be produced 8-12 ton Graphite Electrodes, and quality product is neglected poor extremely unstable.The two also has the common shortcoming, and promptly the pre-heating stage voltage of greying production process is too high relatively, causes great waste of energy, increases production cost.
The utility model content
The purpose of this utility model provides a kind of silicon rectifying transformer cascade graphitizing furnaces, and it can be for graphitizing process provides reasonably big electric current, low voltage, and voltage is stable, effectively reduces the per unit area yield energy consumption, improves the quality of products, and reduces production cost.
For achieving the above object, the technical solution of the utility model is: a kind of silicon rectifying transformer cascade graphitizing furnaces, comprise graphitizing furnace, transformer is connected with graphitizing furnace by switch, conducting plates on the conductive electrode links to each other with transmission of electricity bus on the transformer, and described transformer is provided with rectifying device, and rectifying device is made up of some silicon rectifier composition elements, silicon rectifier composition element one end is connected with the transformer leading-out terminal, and the other end links to each other with the transmission of electricity bus.
Described transformer efficiency is 24000-27500KVA.
Voltage variable block switching arrangement is installed on the described rectifying device.
Described silicon rectifier composition element is a ZpZ type myriampere degree silicon rectifier composition element.
Described conductive electrode is the composite conducting electrode, and the conductive electrode both ends or one end are provided with pressurizing device.
The utility model is provided with the rectifying device of being made up of the silicon rectifier composition element on transformer, after the rectifying device rectification, can offer big electric current of graphitizing furnace and stable low voltage, product power consumption 3000-4000 degree per ton, energy efficient greatly, improve product quality and yield, reduce production costs, improve enterprise competitiveness.Transformer efficiency is 24000-27500KVA, can satisfy the scale operation needs, improves output.Voltage variable block switching arrangement is installed on the rectifying device, makes voltage, make the voltage conversion gradually from high to low of graphitizing process pre-heating stage, satisfy the voltage needs in waste heat stage, cut down the consumption of energy, save production cost from the 50V-115V conversion.
