CASEMASTER EVOLUTION<\/h1>\n

<\/h3>\n

Unique technology uses high temperature and low pressure carburizing to replace\u00a0conventional sealed quench furnaces by achieving shorter cycle times and higher production rates<\/h3>\n

[\/et_pb_text][et_pb_text _builder_version=”3.27.4″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” use_border_color=”off” global_colors_info=”{}”]<\/p>\n

<\/h3>\n

The CaseMaster Evolution has been designed using state of the art construction, with processing chamber & loading vestibule, incorporating a quench tank. Cooling may be carried out in two ways: under neutral gas or in hardening oil.\u00a0Durable graphite insulation and heating elements provide long, reliable service in this heavy-duty furnace designed for industrial applications. The convection heating system ensures rapid and uniform heating of the load at low temperatures also, which shortens the heat-up time. The high efficiency oil agitation system ensures excellent oil penetration through the workload which results in uniform and fast charge cooling. The gas system, pump system, power supply and cooling systems are generously sized to enable a wide range of industrial heat treatment implementations.<\/span><\/p>\n

Efficiency & Quality<\/h3>\n

\/<\/span> Increased efficiency because of shorter carburizing cycle times as a result of very high carbon transition into the workload & high dissociation rate in the pertinent temperature ranges of up to 1050\u00b0C \/<\/span> Greater results repeatability in terms of parts and workloads \/<\/span> No intergranular oxidation because of oxygen-free atmosphere<\/p>\n

Environment Impact<\/h3>\n

\/<\/span> No CO\/CO2<\/sub> emission \/<\/span> Lack of\u00a0an atmosphere to utilize \/<\/span> No additional, energy consumable equipment i.e.: Endothermic generator \/<\/span> No need of plant ventilation & air conditioning – less heat losses<\/p>\n

Health & Safety<\/h3>\n

\/<\/span> No open fire – no exhaust hoods \/<\/span> Clean, non-toxic work environment \/<\/span> Workplace safety improvement due to lack of\u00a0flammable process gases \/<\/span> Easy & intuitive process control \/<\/span> Visual display of the process parameters \/<\/span> No furnace idling periods, quick start up & shut off of the furnace \/<\/span> No special \u201cfurnace shutting down\u201d procedures \u2013 Just Shut & Go \/<\/span> Process flexibility<\/p>\n
