AI Technical Summary

Technical Problem

Traditional ramming mixes for medium-frequency furnaces suffer from poor environmental performance, easy bond peeling, low density, and insufficient resistance to slag corrosion and thermal shock.

Method used

Using raw materials such as multi-grained white fused alumina, magnesium aluminum spinel, microporous spinel and α-Al2O3 micro powder, combined with specific sintering aids and environmentally friendly silica sol binders, a tightly packed and high-temperature stable structure is formed through precise proportioning and mixing processes.

Benefits of technology

It improves the mechanical properties, thermal shock resistance, and slag erosion resistance of ramming mix, achieving high-temperature strength and stability of environmentally friendly ramming mix, which is in line with the development trend of green manufacturing.
