    • A thermal radiation baffle for apparatus for use in directional solidification of crystalline material, to be mounted at one end of a furnace, and to allow a mould containing the material in molten form to pass through, has at least one clamped layer of interconnected flexible strips of refractory material. Each such layer (12) has an ordered construction, for example, with the strips being interwoven, or knitted; and has one or more slits therein. At least substantially the whole of each slit (16) is inclined at a significant angle to the strips, so that the strips do not become detached or worn in use, but the layer (12) is capable of resiliently engaging the sides of, for example, an irregularly shaped mould. A slit (16) may be provided between two separate, but adjacent, pieces of the layer (12).
    • 用于待安装在炉的一端的结晶材料的定向凝固的设备的热辐射挡板以及允许含有熔融形式的材料的模具通过的热辐射挡板具有至少一个相互连接的柔性条带的夹紧层 耐火材料。 每个这样的层(12)具有有序结构,例如,条被交织或编织; 并且在其中具有一个或多个狭缝。 至少基本上每个狭缝16的整个部分以相当大的角度倾斜,使得条带在使用中不会脱落或磨损,但是层(12)能够弹性地接合 例如,不规则形状的模具。 狭缝(16)可以设置在层(12)的两个分离但相邻的部分之间。
