Nowadays large horizontal retort furnaces are also used. Horizontal retort furnaces of different size and execution are preferred for nitrocarburizing processes. <\/span><span style=\"font-weight: 400\">Figure 24<\/span><span style=\"font-weight: 400\"> shows a schematic of a typical horizontal retort furnace. Similar to the vertical execution, a good circulation of the process gas is needed to get uniform results, which can be reached by the use of a muffle and a high circulation rate. Indirect cooling is performed with an external cooling fan, blowing cold air along the retort. Other designs allow direct cooling of the process gas with an external heat exchanger.<\/span><\/p>\n<p><span style=\"font-weight: 400\">For more information, click on the link below (subscription required).
