Abstract
The utility model relates to a vertical magnesium-smelting reduction furnace, belonging to a reduction apparatus which uses gas as energy sources and adopts a silicothermic process to smelt magnesium. The vertical magnesium-smelting reduction furnace is characterized in that the vertical magnesium-smelting reduction furnace is composed of a furnace body and a reduction pot; the upper part of the furnace body is provided with a combustion chamber, and the lower part is provided with four main combustion chambers and four discharge flues; the reduction pot is a vertical type and is made of 4Cr25Ni20Si2 of high temperature material; four magnesium crystallizers are arranged on four crystalline cooling water sleeves on the upper part of the reduction pot. The utility model has the characteristics of long service life, low energy consumption, pollution abatement, energy saving, high yield, low cost, and good quality. The vertical magnesium-smelting reduction furnace reduces workmen's labor intensity.
Description
It is reduction apparatus-vertical magnesium smelting reducing stove that the energy adopts the silicothermic process smelting magnesium with coal gas that the utility model relates to a kind of.
At present, it is the white steel rotational casting reduction jar that raw material is made that domestic smelting magnesium adopts 3Cr24Ni7Si12, yielding in the high-temperature vacuum smelting process, only be 3～4 months work-ing life, 15～17 tons of ton magnesium consumption of coal, the heat energy utilization rate only reaches 30～40%, the flue dust severe overweight that discharges in smelting process, exist work-ing life short, energy consumption big, the shortcoming of contaminate environment, and yield poorly, of poor quality.Every jar one-pot material 120kg goes out magnesium 16～18kg, and material magnesium ratio is 7: 1, and crystallization magnesium purity is low, foreign matter content is big, and 12 hours production cycles, cost height, labor strength are big.
The purpose of this utility model provides a kind of not yielding in high-temperature vacuum is smelted, and save energy, reduction coal consumption, reduces the reduction apparatus-vertical magnesium smelting reducing stove smelting magnesium environmental pollution, that adopt the silicothermic process smelting magnesium.
The utility model vertical magnesium smelting reducing stove content Description:
The utility model vertical magnesium smelting reducing stove is characterized in that being made up of body of heater, reduction jar two portions; The internal layer of body of heater is to be built by laying bricks or stones by fireclay brick, the fire-retardent fiber felt-rug thermal insulation layer is established in the centre, its shell adopts steel plate to make, constitute by upper and lower two portions, a combustion chamber is arranged on the top of body of heater, the bottom of body of heater is provided with four primary chamber and four smoke-uptakes of being " ten " font, and the burner and the inlet pipe of a coal powder injection gas (or oil spout) all arranged in each primary chamber inside; The reduction jar is the formula that stands, adopt the 4Cr25Ni20Si2 high temperature material to make, one dog-house is set at the top, a slag-drip opening is established in the bottom, upper and lower twice expansion joint is established on middle part and top at tank body, at built-in 20～30 the interior fever pipes of reduction tank body, the center of tank body is provided with a hollow webmaster at the middle part of epimere material mouth and bottom slag-drip opening, separate by the mouse cage net between tank body and heat-generating pipe, form magnesium gas passage and vacuumize in smelting, top is provided with four magnesium crystallizers in four crystallization watercooling jackets.
The utility model vertical magnesium smelting reducing stove, a reduction jar employing 4Cr25Ni20Si2 high temperature material is made, and is not yielding in high-temperature vacuum is smelted, and can reach work-ing life more than 1 year, and a ton magnesium consumption of coal is 5～5.5 tons; Keep 1200 ℃ of reduction temperature consumption coal gas by original 1000～1200m
3/ h reduces to 370～400m
3/ h, the heat energy utilization rate is up to 80%; Adopt semi-automatic vertical deslagging, semiclosed car connects slag makes dust concentration and dust concentration be significantly less than the national requirements for environmental protection emission standard; Vacuum is produced half that unit is only used old-fashioned reduction jar, economize on electricity 50%, and the refining magnesium time foreshortened to 6～8 hours by 12 hours, and first magnesium crystallization purity improves 2%.Have cutting down the consumption of energy, alleviate environmental pollution, save energy, output height, characteristics that cost is low.
