Zhengzhou City shangzhuang Refractories Co. (www.yntjj.com.cn) is located in Zhengzhou City, Henan Province, Zhengzhou Xinmi shangzhuang Industrial Development Zone, Contact: Cheng Haitao Refractories Co., Ltd., Zhengzhou City shangzhuang learned flame gunning method flame spray stoppage, finished molten refractory powder particles from a liquid or gaseous fuel in the flame, and is sent simultaneously on the surface to be repaired. At this time the flame nozzle masonry is supplemented heated, would not need to make special temperature limits when using this method, and can use less expensive to obtain high quality refractory gunning powder layer. Principle ceramic welding method ceramic welding method is that the addition of a strong oxidizing agent to the compound - aluminum and silicon. The aid of oxygen flame nozzle way wind transport law, the oxidant together with refractory powder to the surface to be repaired. Refractories Co., Ltd., Zhengzhou City shangzhuang understand refractory wear depends on the composition and structure of the material. When a single crystal material is composed of a dense polycrystalline high alumina clay casting material, depending on the hardness of the wear resistance of the material composition of mineral crystals. High hardness, high wear resistance. When the mineral crystal is isotropic when extraordinary high alumina brick castable, fine grain, high wear resistance. When the material is constituted by a multi-phase high-alumina clay casting material, wear resistance also with the bulk density or porosity of the material is directly related to high-alumina clay casting material, also in conjunction with the relevant classification in each group. Thus, at room temperature for a certain kind of refractory material is concerned, the wear resistance is proportional to its compressive strength, the sintered article of good abrasion resistance is also good. The wear resistance of refractory products related to temperature.
