Description
ИзОбретеиие отпоситс к области моделировани процеосое лить агеталлоз и |СПла1ВО В.The Invention relates to the field of modeling the process of pouring aga tallose and |
Известен способ моделировани процессов теплопередачи путем заполнени формы расплавами веществ с низкой температурой плавлени , например парафином, стеарппом Hi т. п.There is a method of modeling heat transfer processes by filling the form with melts of substances with a low melting point, for example, paraffin, Hi-Stearpp, etc.
Применение подобных теплоносителей представл ет значительные «еудобсрва, св занные с необходи.мостью их расплавлени перед заполнением формы и последующим выходом ИЗ стро разовой формы (о-болочки), в которую они залиты. Кроме того, при расплавлении теплоносителей создаютс вредные услови труда, что также ограничивает их применение.The use of such coolants represents a significant amount of food associated with the need to melt them before filling out the form and then exiting from the system of a one-time form (o-bore) into which they are poured. In addition, when the coolants melt, harmful working conditions are created, which also limits their use.
Цель изобретени - расширить интервал температур моделировани и упростить процесс .The purpose of the invention is to extend the temperature range of the simulation and simplify the process.
Это достигаетс тем, что в качестве теплоносител используют зерновые массы высокой ПОД1ВИЖПОСТИ (например, сухой .кварцевый песок, графитовые шарики, металлическа дробь и др.). Это ликвидирует необходимость в подборе и расплаве специальных теплоноЮителей и позвол ет .многократно использовать оболочковую форму и теплоноситель дл процесса моделировани без -какихлибо специальных мер (выжигани , промывани . формы и т. п.).This is achieved by using grain masses of high ACCURACILITY as a coolant (for example, dry quartz sand, graphite balls, metal shot, etc.). This eliminates the need to select and melt special heat transfer agents and allows the shell mold and coolant to be used many times for the simulation process without any special measures (burning out, washing, mold, etc.).
Область применени пред.тоженных теплоносителей достаточпо широка. Они не создают вредных условий труда и с их помощью можно исследовать процесс охлажде№и (нагрева ) тел са.мой различной конфигурации (отливки, поковки и т. п.) при различных те.хнологи1ческих процессах (литье, термической обработке и т. п.) и в широких интервалах температур.The range of application of the preferred coolants is wide enough. They do not create harmful working conditions and with their help it is possible to investigate the process of cooling (heating) with bodies of various configurations (casting, forgings, etc.) under various technological processes (casting, heat treatment, etc. .) and in wide temperature ranges.
