Thermal conductivity hi physical indicator a ni a, glass kiln-a silica brick quality sang tak takte thermal conductivity characterize-tu a ni a, a value chu heat flux nen a inang a, tunlai negative temperature gradient. nen a zat a ni a, Luoyang Mele Xiaobian chuan refracty materials-te heat capacity leh conductivity chu a rawn luhtir duh che a ni. A chanchin hi kan zir dun ang!
Heat 1000 a ni.
Eng thil pawh a lum chuan a lum a, mahse a mass inang chiah chiah thil chi hrang hrang chuan heat zat hrang hrang a mamawh a,℃1℃. a tihlum a, a tlangpuiin normal pressure hnuaia material kg 1 a lum a, temperature 1℃a tihsan nan a mamawh heat (KJ) a ni a, chu chu heat capacity (specific heat capacity an ti bawk). a ni.
Temperature conductivity .
Temperature conductivity chu thil a lum laiin temperature transfer speed a ni a, chu chuan silica brick chu rang taka tihlum leh tihlum a nih chuan a chhunga temperature gradient size a tichiang a ni. Thermal conductivity chu thermal conductivity ( ) hmanga tarlan a ni::
=λ/cρ
Formula ah chuan:
Λ——Refractory thila thil awm dan (thermal conductivity), w/m.k;
C——Isobaric heat capacity of refractory material, KJ/KG.℃;
ρ——bulk density of refractory, kg/m3.
A tlangpuiin silica brick-te heat capacity hi a danglam vak lo va, an temperature conductivity chu a bulpui ber chu product. thermal conductivity leh bulk density-ah a innghat a ni.
Conductivity 1000 a ni.
Calcium-free silica brick te hi room temperature-a electric conductor tha lo an ni. temperature a san chuan, resistance a tlahniam a, conductivity a san chuan. a sang hle a, a bik takin temperature chu 1000℃. aia sang a nih chuan, molten state-a a lum chuan electrical conductivity nasa tak a lantir ang.
