Chrome-free brick for lining of vacuum refining furnace and preparation method of chrome-free brick
The invention relates to a refractory material and a preparation method thereof and particularly relates to a chrome-free brick for a lining of a vacuum refining furnace and a preparation method of the chrome-free brick. The chrome-free brick is prepared from the following components in parts by weight: 15-18 parts of fused magnesia coarse particles, 20-25 parts of fused magnesia fine particles, 20-25 parts of fused magnesia fine powder, 2-5 parts of ZrAl3 powder, 3-6 parts of alpha-alumina micro powder, 5-10 parts of metallic aluminum, 10-15 parts of fused spinel powder, 5-10 parts of ZrO2 and 3-5 parts of liquid-state phenolic resin. The chrome-free brick has the characteristics of good slag erosion resistance, high high-temperature strength, relatively high density, environmental friendliness and the like; and a production method is simple, the raw materials do not contain chrome, and the comprehensive usability of the chrome-free brick is superior to that of a magnesium-chrome brick.
