1results about How to "Improve high temperature flexural strength" patented technology

This invention relates to the field of green special refractory ceramics technology, and particularly to a green refractory thermal shock resistant converter slag-blocking sliding plate and its preparation method. The raw materials for the aforementioned green refractory thermal shock resistant converter slag-blocking sliding plate, by weight, include: 50-80 parts of tabular corundum particles, 10-20 parts of fine tabular corundum powder, 1-3 parts of α-alumina micro powder, 5-10 parts of zirconium mullite, 5-10 parts of dispersed graphite, 1-2 parts of carbon fiber, 1-2 parts of silica micro powder, 1-2 parts of titanium powder, 1-5 parts of boron nitride, 1-5 parts of boron carbide, and 1-3 parts of phenolic resin; the raw materials for the dispersed graphite include: flake graphite powder, ferric nitrate, urea, potassium nitrate, and surfactant; the mass ratio of flake graphite powder, ferric nitrate, urea, potassium nitrate, and surfactant is 5-10:1-3:1-3:1-2:1-2. The thermal shock resistance, compressive strength, and high-temperature flexural strength of the converter slag-blocking sliding plate obtained by this invention are simultaneously improved.
