Investment Dewax Ovens.Flashfire dewax ovens are available from Ransom & Randolph. The Yorkaire dewax oven offers the investment caster an alternative to existing autoclave autoclave Vessel, usually of steel, able to withstand high temperatures and pressures. The chemical industry uses various types of autoclaves in manufacturing dyes and in other chemical reactions requiring high pressures. and flashfire technology. The oven was developed to operate simply with the fewest moving parts Moving parts are the components of a device that undergo continuous or frequent motion, most commonly rotation. "Parts" only include the mechanical components which does not include fuel, or any other gas or liquid. possible. The ovens have two main compartments: the lower chamber where the dewaxing is done and the upper chamber, which acts as the thermal reactor or afterburner afterburner Second combustion chamber in a turbojet or turbofan engine, immediately in front of the engine's exhaust nozzle. The injection and combustion of extra fuel in this chamber provide additional thrust for takeoff or supersonic flight; in most cases, the afterburner section. The dewaxing chamber features a modular refractory hearth with integrated drainports. Ceramic shells are placed over these drainports and after the door is closed, the burners quickly reach the target temperature for dewaxing the mold. As the wax melts, it is collected in a water bath located under the ports for recycling or other processing. The afterburner is designed to quickly accommodate the hydrocarbon load that is generated in the lower combustion chamber. In the upper chamber, the hydrocarbon dwell time and temperature ensure complete combustion. Depending on the wax load, cycle time is 10 -15 min. The oven is fired by natural gas or vaporized va·por·ize tr. & intr.v. va·por·ized, va·por·iz·ing, va·por·iz·es To convert or be converted into vapor. va LP gas.
