耐火纤维面板 Refractory fiber panel-工业窑炉耐火材料部件-唐山阿尔菲索耐火纤维有限公司

由于窑炉的工作温度越来越高，甚至达到了耐火纤维模块的使用温度极限，同时炉里的有害气氛也加速炉衬的损坏，炉衬减薄造成炉外壁温度上升，能耗增加。更换炉衬需要长时间停炉。

由于更换产品和使用新的技术，所需工作温度超出现有窑炉的工作温度极限，不得不更换炉衬模块，有的甚至需要使用氧化铝纤维毯做的模块，需要极高的成本。

现在有了经济而快捷的解决方案，即在现有陶瓷纤维模块炉衬上，安装ALFISO的面板系统。面板系统包括经过锻烧、加工的真空成型板以及陶瓷锚固件。锚固件直接安装在模块上，耐火纤维面板四边均有错缝搭接，避免贯穿缝，安装后，用我们的同等温度的纤维可塑料充填缝隙，形成一个整体。可以根据实际工作条件选用不同厚度、温度的面板，最高可达1800 °C。面板可以保护其后面的纤维模块，避免其超温或受气氛影响。

制作陶瓷纤维模块所使用的陶瓷纤维毯中，纤维是靠针刺，而不是用结合剂粘结在一起，有时不能满足环保或人员防护方面的要求，这种情况下，可以使用陶瓷纤维真空成型面板系统，甚至可溶性纤维制成的面板，以实现清洁的，符合要求的环境。

产品特点：

► 无须拆除原由模块炉衬，直接安装，可降低成本，减少停炉时间
► 有多种纤维材料可供选择，包括可溶性纤维

Due to the constantly increasing working temperatures which are reaching fiber modules application limits, and hazardous atmospheres in furnaces accelerate the damaging of the lining. The exterior wall temperature rises with industrial furnaces where the entire insulating layer has been significantly reduced by high temperature, chemical attack or mechanical destruction. The furnaces have to be stopped long time for changing the lining with new modules.

Some companies operate existing industrial furnaces at higher temperatures than originally set forth when they change products or technologies, the module lining of the furnaces may not meet the higher temperature, it has to be replaced with higher grade fiber modules with much higher cost.

Now, the solution become simple and cheaper, with our rehabilitation system of vacuum-formed, prefired front panels, which can be installed directly onto the existing module wall using ceramic anchors (applicable up to 1700°C). Depending on operating temperature and operating conditions, front panels with different classification temperatures up to 1800 °C. These front plates ensure that the module lining behind are not exposed to higher temperatures than its limit.

Some other areas of application are the assembling front plates of bio-soluble fibers or the new (fiber-free) vacuum-formed material on existing ceramic fiber modules. TRGS 521,i.e.the Technical Rules for Hazardous Substances, published in May 2002 in Technische Regeln fur Gefahrenstoffe - Bundesarbeitsblatt 5/2002(Germany),states that products should be selected to keep the release of fiber dusts as low as possible. The ceramic fibers are needled, but not bonded to one another in blankets or modules. The current issue of TRGS 521 recommends using the pre-packaged products, molded pieces or products with a favorable dusting behavior (from bound fibers). All 3 conditions are satisfied by the front plate system depending upon fiber quality or surface treatment .The requirements of TRGS 521 are not only satisfied by encapsulating module insulation with the appropriate pre-treated/pre-heated vacuum-formed front plates, it also creates an additional form of energy-saving insulation.

Advantages

► Instead of completely new lining with long shutdown times and high cost, the front panel system allows for an economically durable rehabilitation.
► The possibility of being able to select from different fiber qualities (also bio-soluble fibers).
