On PVA graphite reactor used imported products on the pricing

　　March 27, 2008 Zhuzhou Cemented Carbide Group received a bit of help from telephone factory, and its imports of PVA sintered graphite furnace has burned body heat production, the company wanted me to help mapping, production, quickly restore production and reduce production losses .
         In the absence of drawings, non-technical information, delivery time, I related to a company's technical experts and professionals from the plant to carry out site survey, drawing drawings, work overtime in the four days to complete production tasks, and all night the night to help install and debugging, to quickly restore production and reduce the possible loss of the plant.
         The graphite products for the United States imports of graphite materials, priced at 280 / Kg, the weight of their supplies and processing fees calculation, see annex I. Its technical quality indicators for the bulk density ≥ 1.85g/cm3, resistivity ≤ 11.5μΩm, ash ≤ 100PPm, compressive strength ≥ 65MPa, its mechanical strength, chemical purity, thermal shock resistance, high temperature heat value of the region, with the PVA furnace sintered products in the atmosphere and the basic matching requirements. However, selection was limited to stock specifications, processing tasks tight arc span, and the CD can not be set, nor can it take more measures to conserve materials, it was not the best termination based on results, and more than a hundred kilograms of leftover bits and pieces left over material . The calculation of the material is expected, under the guidance of Professor Jiang Wenzhong personally carried out, under the specific materials and processing, such as Figure 2.
        Imports of similar products, such as procurement, whether in Germany or Japan, the manufacturer will require a two-month cycle, and the materials are not necessarily equipped to adapt to your company's production needs, not to field testing and installation.
        The above-mentioned graphite body heat by the bit of the sintering plant to use a few months, it is functioning well, so that the plant and your group of PVA graphite furnace body made of heat transformation, import substitution, to be successful. The future of your company to repair this type of sintering furnace, the spot in time to provide the necessary accessories, the rapid resumption of production, is of great practical significance.
