uas refractory cib siv nyob rau hauv qhov cub kub kub?

Refractory bricks for hot blast stoves include clay bricks, silica bricks, and high-alumina refractory bricks (including mullite bricks, sillimanite bricks, andalusite bricks, kyanite bricks, and corpus callosum bricks). The general requirements of hot blast stoves for refractory bricks are: low creep rate, good high temperature strength, and good thermal shock resistance. In addition to meeting the above requirements, checkered bricks for hot blast stoves should also have a larger heat capacity. In order to select refractory bricks reasonably in the design of hot blast stove, we must first understand the performance of refractory bricks. Because accurate refractory material characteristic parameters are the basis to ensure correct and reliable design.

Lub neej kev pab cuam ntawm lub qhov cub kub kub yog qhov ntev heev, feem ntau yuav tsum tau 10-20 xyoo. Refractories dais hnyav vim lawv qhov hnyav. Yog li ntawd, refractories nrog zoo heev creep kuj yuav tsum tau siv nyob rau hauv high kub loads. Qhov kub-kub creep tsis kam ntawm silica bricks yog qhov zoo tshaj plaws, thiab qhov kub-kub creep yog tsawg heev; ua raws los ntawm high-alumina cib, nrog rau high-alumina cib ua los ntawm high-alumina clinker thiab sillimanite minerals, uas muaj zoo kub-kub creep zog. Qhov ze nws cov muaj pes tsawg leeg yog mullite, qhov zoo dua qhov creep kuj ntawm cib.
