活性石灰

Active Lime

 

一、活性石灰

活性石灰不同于一般石灰,它具有气孔率高(50%)、表面积大(1.6-2m2/g)、活性度高(360ml)、硫含量低等特点;活性石灰用于钢铁、氧化铝、金属镁、电石的生产,造纸、以及电厂脱硫等行业。

Other than ordinary lime, active lime bears a series of features, such as high porosity (50%), large surface area(1.6~2m2/g), great degree of activity and low content of sulfur, etc. Active lime is widely used in the production of steel and iron, alumina, magnesium and calcium carbide, paper making as well as desulfurization in power plant, so on and so forth.

 

     石灰的活性度是指它在熔渣中与其它物质的反应能力,通常用石灰与水的反应速度表示,在标准大气压下10分钟内,50克石灰(1-5mm)溶于40℃恒温水中所消耗HCl(4mol/L)溶液的毫升数定义为石灰的活性度。

Activity degree of lime is regarded as the reaction ability of molten slag with other materials, usually denoted by reaction velocity of lime and water. Under standard atmosphere, dissolve 50g lime(1-5mm)into water of  40℃ constant temperature, milliliters of HCI (4mol/L) solution consumed within ten minutes are defined to be the activity degree of lime.

 

二、活性石灰用途Use of active lime

 

用于炼钢,能够提高脱磷、脱硫效率(50-70%),缩短冶炼时间(1-2min),提高炉龄、降低石灰消耗(10-30%),降低炉料消耗(5-8kg/t)。

Used to make steel, increase dephosphorization and desulfurization effect(50-70%),shorten smelting time(1-2min),elevate furnace life, decrease lime consumption(10-30%)and loading consumption (5-8kg/t).

 

用于烧结配料,能显著提高混合料温度,提高混合料成球率,改善透气性,降低燃料消耗,烧结产量提高3~5%,燃料消耗降低3~5%,FeO降低1~2%、石灰消耗降低15%。

Used for sinter proportioning, being able to evidently increase the temperature of mixture, enhance the granulation rate of mixture, improve the permeability, reduce fuel consumption. As a result, sintering production heightens 3~5%,consumption of fuel decreases 3~5%,FeO falls 1~2% and consumption of lime lowers 15%.

 

用于拜尔法生产氧化铝,能显著提高氧化铝的产量和质量.

Used for producing alumina by means of Bayer Process, thus can obviously enhance the output and quality of alumina.

 

用活性石灰冶炼电石能起到冶炼时间短、电石品位高,节省电耗等作用

Smelting calcium carbide with active lime can shorten smelting time, elevate the quality of calcium carbide, save electric power and all like.

 

用于烟气脱硫,提高提高SO2的吸收率、减少脱硫产物

 Used for flue gas desulfurization, lighten absorption of SO2, and lessen desulfurizing output.
