<\/strong><\/u>Roller Hearth conveyor systems consist of a\u00a0series of externally driven rolls.\u00a0 There are no\u00a0cumulative conveyor pressures or\u00a0tensions as\u00a0in\u00a0belt, chain or\u00a0pusher furnaces.\u00a0 As\u00a0a\u00a0result, there are no\u00a0production or\u00a0cycle limitations and the length of the furnace is dependent only upon your application needs.\u00a0 Individual operation of the roll sections permits continuous or\u00a0interrupted workflow.<\/p>\n
<\/strong><\/u>The advanced design features of these furnaces let you increase both the quality and rate of your production.\u00a0 Individually driven roll sections allow for fast run-in and run-out. Heavy-duty insulation systems, welded gas-tight casings and thermal isolation doors all assure fast, accurate, uniform heating and cooling, all of which minimize atmosphere mixing, heat loss and work distortion or\u00a0stress.<\/p>\n
<\/u><\/strong>Furnace sections are completely assembled at\u00a0the factory with insulation, heating systems, piping, wiring, and rollers. The skid-mounted sections can be\u00a0moved quickly and easily into place, welded or\u00a0bolted together and placed in\u00a0operation. Modular design allows each section to\u00a0be\u00a0preassembled by\u00a0highly skilled factory technicians using the right tools, jigs and fixtures, assuring greater attention to\u00a0workmanship and design details, eliminating many of the problems frequently encountered with field construction.<\/p>\n
<\/u><\/strong>Because individual conveyor rolls are externally driven and remain in\u00a0the same temperature zones, they are not subject to\u00a0thermal cycling and can be\u00a0designed for maximum operation life at\u00a0working temperatures.\u00a0 In\u00a0addition, cumulative pressures on\u00a0conveyor rolls, work trays and workloads are eliminated.\u00a0 Furnace doors are specially constructed and insulated for operation within the temperature zones in\u00a0which they are located, minimizing stress and warpage caused by\u00a0temperature differences.\u00a0 Heating and cooling sections incorporate dependable, high-quality components for long life operation. Factory assembly of the furnace section eliminates many problems often encountered with field construction.<\/p>\n
<\/u><\/strong>Individual roll sections can be\u00a0started, stopped, reversed or\u00a0oscillated; they can be\u00a0run at\u00a0the same or\u00a0different speeds.\u00a0 This permits an operating furnace that produces your required cycle in\u00a0a\u00a0minimum amount of space.\u00a0 High-speed transfer between sections allows closely spaced workloads or\u00a0work trays, along with workpiece separation during transfer through doors, assures the optimum use of hearth space and minimizes atmosphere mixing.\u00a0 All door openings can be\u00a0adjusted to\u00a0workload heights, permitting faster operation and minimizing contamination of controlled atmosphere.<\/p>\n
<\/u><\/strong>The wide selection of furnace combinations and sizes means that you can get the furnace designed for your needs.\u00a0 You can cut costs through increased product quality and rate of production.\u00a0 Factory assembly means lower cost installation and your furnace is in\u00a0production more quickly.\u00a0 In\u00a0addition, the best construction materials and design mean minimal maintenance.<\/p>\n
<\/u><\/strong>Cycle annealing produces a\u00a0tough, uniform structure in\u00a0steel.\u00a0 A\u00a0Roller Hearth annealing furnace can improve the machinability of screw machine stock, improve cold working properties of deep drawing stock, and improve impact resistance & fatigue properties of gears or\u00a0machine parts.\u00a0 In\u00a0the furnace, the steel is heated to\u00a0slightly above hardening temperature (approx. 1700\u00b0F\/925\u00b0C), cooled quickly to\u00a0the temperature at\u00a0which transformation should take place (approx. 1200\u00b0F\/650\u00b0C), held at\u00a0this temperature until the transformation has taken place and then cooled.\u00a0 This furnace may be\u00a0heated by\u00a0gas-fired radiant tubes or\u00a0by\u00a0electric ribbon resistors, and normally has a\u00a0controlled atmosphere to\u00a0prevent scaling and surface decarburization.\u00a0 Maximum furnace temperature: 1750\u00b0F\/950\u00b0C.<\/p>\n
<\/u>Expensive forged or\u00a0machined parts can frequently be\u00a0replaced by\u00a0copper brazed assemblies of stamped parts.\u00a0 In\u00a0many cases, the copper brazed parts offer quality improvement as\u00a0well as\u00a0a\u00a0cost reduction.\u00a0 The copper brazing furnace normally includes an electrically heated chamber with either alloy ribbon resistors or\u00a0silicon carbide resistors and a\u00a0water-jacketed cooling chamber. Copper brazing furnaces\u00a0operate with a\u00a0reducing atmosphere to\u00a0prevent oxides from interfering with the brazing operation. Maximum furnace temperature: 2100\u00b0F\/1150\u00b0C.<\/p>\n
<\/u><\/strong>A\u00a0choice of higher component efficiency or\u00a0lower costs can be\u00a0achieved in\u00a0electric motors, transformers, reactors, and ballasts by\u00a0annealing the magnetic laminations after the last punching, shearing or\u00a0welding operation has been performed.\u00a0 With almost any magnetic steel, the losses are reduced by\u00a0this final annealing.\u00a0 The furnace normally includes a\u00a0burn-off chamber to\u00a0remove lubricants, a\u00a0heat-and-hold chamber, a\u00a0slow cool chamber and an air blast cooling chamber.\u00a0 Heating may be\u00a0by\u00a0gas-fired radiant tubes or\u00a0electric ribbon resistors. The furnace is operated with a\u00a0carefully selected controlled atmosphere. Maximum furnace temperature: 1750\u00b0F\/950\u00b0C.<\/p>\n
<\/strong>This furnace is used to\u00a0improve wear resistance and prevent mechanical deformation\u00a0 of parts such as\u00a0gears, crankshafts and camshafts.\u00a0 The parts may be\u00a0either high carbon hardenable steels or\u00a0carburized lower carbon steels.\u00a0 The heating chamber may be\u00a0heated by\u00a0either gas-fired radiant tubes or\u00a0electrically heated ribbon resistors.\u00a0 The furnace may be\u00a0equipped with an integral elevator type quench system or\u00a0the work may be\u00a0delivered to\u00a0hand, die or\u00a0press quenching stations. The furnace is designed for operation with non-decarburizing protective atmosphere.\u00a0 Maximum furnace temperature: 1750\u00b0F\/950\u00b0C.<\/p>\nSECO\/WARWICK Roller Hearth Furnace Advantages<\/h2>\n
