重燒鎂砂主要的規格有0mm-0.5mm；0mm-1mm；1mm-3mm；3mm-5mm；5mm-10mm；10mm-30mm；50mm-200mm；200mm-500mm；重燒鎂砂產品主要采用高含量菱鎂礦石經過鐵皮豎窯煅燒而成。 重燒鎂砂它是制造生產不定型耐火材料的理想原料，以它為原料 生產的各種耐火材料主要用于鋼鐵工業，也用于玻璃，水泥，和有色冶金行業。因重燒鎂砂具有良好的高溫抗折強度，抗渣性能和抗腐蝕性能，可提高煉鋼爐爐襯的使用壽命，所以被廣泛的用于煉鋼平爐，電爐爐底和搗打爐襯。煉鋼爐的爐襯耐火材料，另外也是制造耐火磚不定型耐火材料的優質理想材料。
What are the specifications of reburned magnesia?
The main specifications of reburned magnesia are 0mm-0.5mm; 0mm-1mm; 1mm-3mm; 3mm-5mm; 5mm-10mm; 10mm-30mm; 50mm-200mm; 200mm-500mm; reburned magnesia products mainly use high content Magnesite ore is calcined by iron shaft kiln. Reburned magnesite is an ideal raw material for the manufacture of amorphous refractory materials. Various refractory materials produced from it are mainly used in the steel industry, but also used in glass, cement, and non-ferrous metallurgy industries. Because reburned magnesia has good high-temperature flexural strength, slag resistance and corrosion resistance, which can improve the service life of steelmaking furnace linings, it is widely used in steelmaking open furnaces, electric furnace bottoms and ramming furnace linings. The furnace lining refractory of the steelmaking furnace is also an ideal high-quality material for the manufacture of refractory bricks.
To distinguish reburned magnesia, you only need to know his production process. The production equipment used for reburned magnesia is a iron shaft kiln. 46% content of magnesite is calcined at 1600 ℃ -1800 ℃. In this case, it can be judged that it is reburned magnesia. The basic main types of reburned magnesia are 80%, 85% and 90%. The main color of reburned magnesia is reddish brown. Reburned magnesia products Widely used in magnesia brick, magnesia-aluminum brick, magnesia-chrome brick, spraying material, castable, dry material, smearing material, filling material, asphalt, casting, fire-proof and heat-preservation material, flux auxiliary material, electrical steelmaking furnace, heating furnace , Rotary furnace, steel making, electric furnace bottom and ramming furnace lining.
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.
