重烧镁砂与大结晶电熔镁砂之间的区别 Difference between reburned magnesia and large crystalline fused magnesia

重烧镁砂主要是采用46%含量菱镁矿石，经铁皮坚窑一层煤一层菱镁石经过1600℃-1800℃煅烧而成的。生产流程是两吨矿石生产出一吨重烧镁砂出来的产品分为三个等级；一、窑前重烧镁砂，二、欠烧重烧镁砂，三、大块重烧镁砂，重烧镁砂产品主要颜色为硬红褐色，重烧镁砂产品特点是具有很高的耐火度。

重烧镁砂产品用途：产品用于镁砖、镁铝砖、镁铬砖 、喷补料、浇注料、干式料、涂抹料、补炉料、沥青、铸造、防火及保温材料、焊剂辅料、电器炼钢炉、加热炉、回转炉、炼钢、电炉炉底和捣打炉衬。

The heavy burned magnesia is mainly made of 46% magnesite ore, calcined at 1600 ℃ -1800 ℃ through a layer of coal and a layer of magnesite in the iron kiln. The production process is that two tons of ore produce one ton of heavy burned magnesia, and the product is divided into three grades; one, the burned magnesite before the kiln, the second, the under burned magnesia, and the third, the large burned magnesia The main color of the reburned magnesite is hard reddish brown. The features of the reburned magnesite are high fire resistance.

Reburned magnesia product use: The product is used for magnesia brick, magnesia-aluminum brick, magnesia-chrome brick, spraying material, pouring material, dry material, smearing material, filling material, asphalt, casting, fire prevention and heat insulation material, flux auxiliary material, Electric steelmaking furnace, heating furnace, rotary furnace, steelmaking, electric furnace bottom and ramming furnace lining.

大结晶电熔镁砂产品主要采用90%含量以上氧化镁0-3颗粒，在电弧炉中熔融制得。该产品具有纯度高，结晶粒大，结构致密，抗渣性强，热震稳定性好，是一种优良的高温电气绝缘材料，也是制作高档镁砖，镁碳砖及不定型耐火材料的重要原料。广泛应用于冶金、化工、国防、科研、航天航空、家用电器元件等。 

Large crystal fused magnesia products are mainly produced by melting 90% or more magnesium oxide 0-3 particles in an electric arc furnace. This product has high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material, and it is also important for the production of high-grade magnesium bricks, magnesium carbon bricks and unshaped refractory materials. raw material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, and household appliance components.
