molybdenum Ferro smelting process

Introduction to the process of producing molybdenum Ferro by outside-furnace method--smelting process

The mixed charge is loaded into the furnace. After the first hopper is added, the finished products and scraps should be added and laid out in a hollow circle. Do not get close to the furnace wall to prevent it from sticking to the furnace wall and not melting. Also, do not leave a reaction path in the center to block the reaction. . After the ring is laid, add the second bucket of charge. After the charge is installed, the distance between the charge surface and the upper edge of the furnace should not be less than 500mm to prevent splashing and overflow during the reaction.

Make a pit in the center of the surface of the charge, add the ignition mixture, insert a steel drill into the ignition object and shake it so that the ignition object communicates with the lower charge. Then add 100g of magnesium shavings as a igniter to the center of the ignition object, straighten the exhaust hood and ignite it with a red fire, and the reaction will proceed automatically.

The changes in the reaction process start from the center downward and spread to the surroundings. Normal response time is less than 10 minutes. In the first 1/4 of the time, the reaction is gentle; in the middle period, the reaction is intense, with a large amount of brown smoke emitted, with boiling and slight splashing; in the last 1/4 of the time, the reaction slows down, the flame is bright, the smoke becomes lighter, and the reaction ends There is obvious light.
