    • The invention relates to an apparatus and method for forming pipe insulation sections of mineral wool. The apparatus features a section curing portion with one or more outer molds (31, 32) cylindrical in terms of their internal surface. The curing portion further includes a core (51, 52) installed inside each mold or capable of being installed therein or removed therefrom. In connection of each outer mold are provided first elements for heating the outer mold at least over its internal surface, and second elements (61, 62; 11, 12; 21, 22) for irradiating a mineral wool section installed in the mold with microwaves, said core having been made from some material capable of heating up in response to microwave irradiation.
    • 本发明涉及一种用于形成矿棉管道绝缘部分的装置和方法。 该装置具有一个截面固化部分,该部分具有一个或多个其内表面为圆柱形的外模具(31,32)。 固化部还包括安装在每个模具内部或能够安装在其中或从其中移除的芯部(51,52)。 在每个外模具的连接处提供用于至少在其内表面上加热外模的第一元件和用于将安装在模具中的矿棉部分照射到微波的第二元件(61,62; 11,12; 21,22) 所述芯是由能够响应于微波照射而升温的某种材料制成的。

    • The invention relates to a method of manufacturing a pipe section of mineral wool, said method comprising the use of an uncured mat of mineral wool, from which is sawn off a run of thin sheet, which is then cut to a length matching the desired wall thickness of a section to be manufactured and which is wound around a core for a sandwich type cylinder, and next the core, and the cylinder of mineral wool around it, are placed in a mould and cured. The method comprises interposing between layers of mineral wool a material (3) better in terms of heat insulation in granular form prior to winding a sheet (1) around a core (2) and/or during the ongoing winding process. The invention relates also to a pipe section, wherein between superimposed layers of mineral wool is provided a material (3), which is in granular form and which is better in terms of heat insulation.
    • 本发明涉及一种制造矿棉管段的方法,所述方法包括使用未固化的矿棉垫,将其从薄片上切下,然后将其切割成与所需壁相匹配的长度 要制造的部分的厚度并且缠绕在用于夹层型圆筒的芯上,并且接下来的芯和围绕它的矿棉圆筒放置在模具中并固化。 该方法包括在将片材(1)缠绕在芯(2)周围和/或在正在进行的缠绕过程之前,以颗粒形式的隔热性更好地材料(3)。 本发明还涉及一种管道部分,其中在叠加的矿棉层之间设置有粒状的材料(3),并且在隔热方面更好。
