Preventing deterioration or destruction of - refractory bricks in steel furnaces
摘要
<p>An insulating refractory coating is applied to the surface of refractory bricks. It reduces the temp. gradient in them during the initial stages of use to a value such, that the thermal stress has an acceptable value. This permits rapid heating so as to commence operations without preliminary drying.</p>
