An effective method is demonstrated for improving the quality of carbon materials and graphite, whose articles are used extensively in different branches of the national economy. This method with use of the "nudel process" includes preparation of a strong and compact filler. The low temperature for filler preparation (550°C) provides a synchronous nature for its shrinkage with the binder during subsequent heat treatment, which reduces to a minimum structural defects for the final material, and as a consequence, it considerably increases the physicomechanical and operating properties similar to the properties of normal high quality materials, and the level of quality for the latter is achieved by repeated production cycles of impregnation of coal tar medium-temperature pitch, i.e. firing. The operational properties of articles made from the material exceeds the similar properties of articles made from traditional materials. The marked production advantages of the suggested version for carbon material using the nudel process are a significant reduction in the time of graphite preparation, a reduction of discharge into the atmosphere of cancerous substances (pitch vapors) and carbon dust; reduced gas flow rate, electric power, spilled materials, and other material expenditures.In various branches of the national economy there is extensive use of carbon materials and articles made from them: fired and self-firing anodes for aluminum electrolyzers, electrodes of ore heating and steel pouring furnaces, crucibles for melting various metals and alloys, furnace heaters for different purposes, etc. Production of carbon materials, for example graphite grade GMZ, is accomplished by a production scheme illustrated in Fig. 1. an increase in their density and strength is achieved as a result of using additional production operations of impregnation with medium-temperature coal tar pitch followed by firing. However, use of additional operations markedly increases the duration of production of carbon materials and graphites, and also their cost, but it avoids considerable nonuniformity of billet properties. This leads to a delay in the development of new fields of contemporary engineering.In order to create new carbon materials, in particular self-firing anodes for aluminum electrolyzers with increased uniformity and operating stability, we have used experience accumulated in developing articles for special technology and other forms of articles made from structural graphite. On the basis of previous experience new specifications have been formulated for the filler: to have a uniform macrostructure with low defectiveness (porosity, cracking); to exhibit high adhesion to the binder; to have the optimum structure depending preparation temperature; to exhibit a good capacity to graphitize (with a requirement of performing a material graphitizing operation).Proceeding from these requirements for preparing a strong anode or graphite with increased operating stability, it
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
