Power saving device for controlling production processes of silicon carbide smelting furnace system by rated value method

Abstract

The invention relates to a power saving device for controlling production processes of silicon carbide smelting furnace system by a rated value method, which comprises an automatically-setting control module of an embedded computer, a voltage regulator, a current regulator, a trigger, a rectifier, a sampling rectifier and the like, wherein the rectifier is formed by connecting a plurality of basic three-phase rectifier bridge circuits in parallel, and balanced reactors are not additionally arranged among the basic three-phase rectifier bridge circuits. Moreover, a 6800A large-power thyristor is used as the rectifying element of the rectifier. The power saving device detects the magnitude of the current and the voltage of a rectifying system and automatically regulates the voltage gear according to the detection results, thereby achieving the purposes of increasing or reducing voltage, keeping the voltage and the current constant, optimizing the quality of products which are produced by the silicon carbide smelting furnace, saving energy and reducing consumption, wherein the power saving rate can reach 10%, and the high-quality product rate is generally improved by 10%, thereby completely reaching the national requirements of energy saving and emission reduction for large-power smelting industries.

Description

technical field [0001] The invention relates to an automatic power-saving device in the production process of a metallurgical system, in particular to a power-saving device for controlling the production process of a silicon carbide smelting furnace system by a rated value method. Background technique [0002] Silicon carbide is a man-made material with a wide range of uses. It is mainly used as abrasive, refractory material, lightning arrester material and silicon carbide rod material. It carries the indispensable main element of modern society---the basic material semiconductor of information technology. With it Our computers, televisions, and wireless communications have all become possible and have become important strategic materials for the progress and prosperity of human society in the world today. Since Acheson, a young American engineer, proposed an industrial method for preparing silicon carbide in 1891, the industrialization of silicon carbide production has firs...

Problems solved by technology

Due to the old-fashioned production technology and methods, the waste of energy and cost is very serious and there are the following problems: ①The existing smelting furnace uses an uncontrollable rectifier device for power supply, the power supply voltage cannot be continuously adjusted, the current pulsation is unstable, and the product quality is low; ②Due to The smelting device is uncontrollable, and the power grid voltage cannot be reasonably rated, so a lot of electric energy is wasted; ③The large waste of electric energy and the low quality of the product have caused the high cost of production electricity and the input of raw materials; "Phenomenon, not only makes the production process unstable, but also easily causes personal safety hazards

It can be seen that with the change of the load of the power grid in a day, a large amount of unnecessary loss is generated, and a large amount of electric energy and funds are wasted.
