8kW高温箱式炉的炉膛两侧各有6根硅碳棒,它的工作部分(φ8mm×180mm)经常因操作不慎而被撞断,造成加热炉断相,温度不均匀,影响工件加热质量。且炉子处于高温,难以及时更换。为避免此现象,可利用保温砖切割成图示成形 8kW high temperature box furnace on both sides of the furnace has six silicon carbide rods, and its working part (φ8mm × 180mm) often due to inadvertent operation was broken, resulting in furnace phase, uneven temperature, affecting the quality of workpiece heating . And the furnace at high temperature, difficult to replace in time. To avoid this phenomenon, the insulation brick can be cut into the shape shown
