功能性無水炮泥采用原料均化和微粉預混技術(shù),用特制復合原料作為外加劑,有良好的抗蝕性,填充性和燒結(jié)性等優(yōu)良的性能,對鐵口裂紋有強制修復功能,它能在鐵口迅速產(chǎn)生一定的抗機械和化學損毀的能力,高溫強度與殘余炮泥結(jié)合性好,而出鐵時又容易開口并保證鐵水和熔渣快通過時沖蝕小,是鐵水和熔渣的流動平穩(wěn),順暢,從而抑制了爐內(nèi)熔渣和鐵水的環(huán)流,減輕了出鐵口周圍爐底側(cè)的襯磚損蝕,很好的保護了高爐鐵口區(qū)域的爐襯及爐缸,有益于延長高爐爐體壽命。
This product uses raw material homogenization and fine powder pre-mixing technology, and uses special composite raw materials as admixtures. It has good properties such as good corrosion resistance, filling properties and sinterability. It has a mandatory repair function for iron cracks. The mouth quickly produces a certain ability to resist mechanical and chemical damage. The high temperature strength is good in combination with the residual gun mud. It is easy to open when the iron is tapped and ensures that the molten iron and slag pass through quickly. It is the flow of molten iron and slag. Smooth and smooth, thereby suppressing the circulation of molten slag and molten iron in the furnace, reducing the corrosion of the lining bricks around the bottom of the furnace, and protecting the lining and hearth of the blast furnace iron mouth area, which is beneficial to extend the blast furnace Furnace life.
