Problems solved by technology

According to the calculation of Planck's law, most of the high-temperature radiation energy is concentrated in the 1-5μm band, but 15-30% of the radiation energy is concentrated in the visible light band 0.4-0.78μm, and the general refractory material's absorption and absorption of these two bands The emissivity is low, which is not conducive to the high temperature radiation heating of the kiln
