隨著煉鋼生產(chǎn)工藝，連鑄和爐外精煉的發(fā)展，使鋼水在鋼包內(nèi)停留時間相對延從而加速了鋼水對包村的損毀，造成鋼包使用壽命低，包齡變短，因此需要高檔次高強耐火鋼包澆注料。
我公司與洛陽耐火材料研究院有關(guān)專家聯(lián)合，經(jīng)過反復(fù)多次實驗，研究生產(chǎn)了高強度耐火鋼包澆注料。它以高純度電熔剛玉為主材料，基質(zhì)中摻加高純度的尖晶石，并加入適量的粘結(jié)劑、外加劑(分散劑、減水劑）等制成。鋼包澆注料具有良好的抗渣性和抗剝性，體積穩(wěn)定性高、強度大、燒結(jié)時間短等優(yōu)點，有效提高包齡和使用壽命。
With the development of steelmaking process, continuous casting and refining outside the furnace, the residence time of molten steel in the ladle is relatively prolonged, thus accelerating the damage of molten steel to the ladle, resulting in low service life and short ladle life, so high-grade high strength steel is needed
Refractory castables.
Through repeated experiments, our company and experts from Luoyang Refractory Research Institute have researched and produced high strength refractory castables. It is made of high-purity fused corundum as the main material, high-purity spinel is added into the matrix, and an appropriate amount of binder and additives (dispersant and water reducer) are added. It has good slag resistance and peel resistance, high volume stability, high strength, short sintering time and other advantages, effectively improving the ladle life and service life.
