A production line for ball press molding and drying of high carbon chromite powder. An ingredient conveyor is connected to a mixer; a mixed material conveyor is arranged between the mixer and a briquetting machine; a high-carbon chromite powder pellet conveyor is arranged between the briquetting machine and a drying room; and a dry ore powder pellet conveyor is between the drying room and a submerged arc furnace. The method is as below: preparing a high-carbon chromite powder material according to the proportion; transporting the material to the mixer by the ingredient conveyor; conducting humidifying mixing treatment to obtain a humidified mixed high carbon chromite powder material; conveying the humidified mixed high carbon chromite powder material by the mixed material conveyor into the briquetting machine, and preparing high-carbon chromite powder material ball block according to predetermined size; and conveying the ball block by the high-carbon block chromite powder pellet conveyor to the drying room for drying, so as to obtain dried ball block suitable for direct calcination; and conveying the dried ball block by the dry ore powder pellet conveyor directly to the submerged arc furnace for calcination process.
Description
technical field [0001] The invention relates to high-carbon ferrochromium smelting raw material processing equipment, in particular to a high-carbon chromite powder briquetting and drying production line. The specific application is in the process of high-carbon ferrochromium smelting production. It is a production line that presses high-carbon chromite powder into balls and then dries them for high-carbon ferrochromium smelting. Background technique [0002] Since chromium is the most versatile metal, it ranks first in "strategic metals". In today's world, countries with chrome ore resources or countries that lack resources are stepping up research on chrome ore development. The raw materials for smelting high-carbon soldering iron are chrome ore, coke and silica; the coke and silica are used as reducing agents. In the chrome ore resources, lump ore raw materials only account for 20% of the total, and the remaining 80% are fine ore. Most chromium ore is a brittle ore, wh...
