目前,我国耐火材料工业中的隧道窑,其热工自控系统几乎都采用五十年代延续下来的极为落后的系统(即对影响窑温的一些主要热工参数施加定值调节,间接地达到稳定窑温的系统)这种系统的
At present, almost all of the tunnel kilns in the refractory industry in China are based on the extremely backward systems inherited from the 1950s (ie, the thermal regulation is indirectly applied to some major thermal parameters that affect the kiln temperature) Kiln temperature system) of this system
