Deslagging method for reduction furnace, deslagging system of reduction furnace constructed according to the method

Abstract

The invention discloses a reducing furnace deslagging method in metal vacuum melting, and a reducing furnace deslagging system which is constructed according to the method. In the method, a reductor is slantways arranged in a reducing furnace or the bottom of the reductor is produced to an oblique state to lead a deslagging port of the reductor to be positioned at the undermost end of the obliquereductor; a reject valve is arranged at the deslagging port, an insulator is arranged in the deslagging port in front of the reject valve, and a movable slag-guiding device is arranged under the reject valve; when in deslagging, the slag-guiding device is connected with the reject valve, the reject valve is opened, the insulator in the deslagging port falls into an insulator storage section in the slag-guiding device, and reducing slag is caused to fall into a slag-guiding groove through the slag-guiding device and is carried away by a slag-conveying device after being cooled by a slag-cooler. The reducing furnace deslagging method and the reducing furnace deslagging system can increase the deslagging efficiency, reduce the heat loss in a reduction kettle, reduces the energy consumption, increase the production capacity, and improve the labor conditions of workers.

Description

technical field [0001] The invention relates to a slagging method of smelting equipment, in particular to a slagging method of a metal vacuum smelting reduction furnace and a reduction furnace slagging system constructed according to the method. Background technique [0002] At present, in the smelting and production of metal vacuum reduction, it is necessary to send the reduced material produced through the batching and pressing process into the reduction tank for high-temperature reduction reaction. According to the difference of the reducing agent, the reduction reaction temperature is generally required to be between 1000 and 1300 °C , the pressure is less than 13Pa. When carrying out metal vacuum smelting, use a reducer for reduction. The reducer can use a reduction tank or a reduction kettle. The reduction tank has a tubular structure. Generally, the volume of the reduction tank is relatively small, which is suitable for the reduction reaction of a small amount of redu...

Problems solved by technology

This method has many disadvantages, the first is slow speed, the second is high-temperature baking, the operating conditions are bad and unsafe, and moreover, directly discharging the slag on the ground will generate a large amount of dust and form serious environmental pollution. bad working environment

Moreover, the existing methods of slag removal and slag removal all delay time, affect production efficiency, waste energy, and affect the economic benefits of the entire enterprise.
