Description
Примен емый в насто щее врем процесс газовой цементацин основан на нсполь.юзании газа, нолучаемого в результате пиролнза керосина либо с ч;1стичным последующим крекированием пиролизного газа в присутствии паров воды.The currently used process of cementacin gas is based on the use of gas produced as a result of pyrolysis of kerosene or with a regular subsequent cracking of the pyrolysis gas in the presence of water vapor.
Указанный процесс имеет р д усложи юш.нх его недостатков: 1) процесс пиролиза керосина вызывает отложение сажи в ретортах, что требует частых чисток; 2) пиролизный газ, а также крекированный пиролизмый газ требует очистки от смол, дл чего необходимо сооружение очистительных агрегатов; 3) выделение сажи из смол засор ет трубопроводы , регулируклцие распределение газа, что Г1риводит часто к нарушению процесса газовой цементации; 4) изменение состава газа но тем или другим Г1ричи1гам создает трудности регулировани процесса.This process has a number of complicate its shortcomings: 1) the process of pyrolysis of kerosene causes soot deposition in the retorts, which requires frequent cleaning; 2) pyrolysis gas, as well as cracked pyrolysis gas, requires purification from tar, which requires the construction of purification units; 3) the release of soot from the tar clogs the pipelines, regulates the gas distribution, which often leads to disruption of the gas cementation process; 4) a change in the composition of the gas but one or the other of them makes it difficult to regulate the process.
Цель насто щего изобретени - усовершенствовать этот нроцесс и создать новый способ получени газов дл цементации, унрогцающш технологию и повышающий качества цементацин.The purpose of the present invention is to improve this process and create a new method of producing gases for carburizing, cementation technology and quality improvement.
Предлагаемый способ получени газов дл целей газовой цементацин исключает необходимость примеиени ииролиза и очистки газов и дает возможность использовать в качеС1ве исходного продукта бо.тео дешевые продукты иефтеиерегонки.The proposed method for the production of gases for the purpose of gaseous cementacin eliminates the need for the application of pyrolysis and gas cleaning and makes it possible to use more cheap products and distillation as a starting material.
Отличительной особенностью предлагаемого способа получени газовой среды дл цементации металлов на основе малоактивных газов, обогащенных жндкими углеводородами, вл етс неполное сгорание топлива с применением воздуха или паров воды и пропускание получепного газа через жидкий .тетучий нефтепродукт.A distinctive feature of the proposed method of obtaining a gaseous medium for cementation of metals based on low-level gases enriched with hydrocarbons is the incomplete combustion of fuel using air or water vapor and passing the resulting gas through a liquid volatile oil product.
