We developed an experimental testbed for micro and macro studies of thermal flux densities in refractories as well as their thermomechanical properties. We studied the effect of thermal stress, temperature field, and the size and shape of the products (under various conditions describing heating of the functional surfaces of the products) on the thermal stability of refractories. We showed that decreasing the side length of the refractory working surface increases the thermal flux density and heat flux without disturbing the structural integrity of the refractory material. We studied the distribution of refractory temperature fields associated with changes in the surface heating rate and surface shape.

耐火材料的热应力和参数对内部温度场发展的影响

我们开发了一个实验性试验台，用于微观和宏观研究耐火材料的热通量密度及其热机械性能。我们研究了热应力，温度场以及产品尺寸和形状（在描述产品功能表面加热的各种条件下）对耐火材料热稳定性的影响。我们发现减小耐火材料工作面的边长会增加热通量密度和热通量，而不会影响耐火材料的结构完整性。我们研究了与表面加热速率和表面形状变化相关的耐火温度场的分布。
