Configuration
   Configuration       
   Your choices are...         
   Ashing       Ashing is also referred to as charring; this is the step in a graphite furnace AA program that is designed to remove matrix constituents that might interfere with the measurement of the analyte. Ashing temperatures vary from 200º to 1800° C, depending on the matrix and analyte element. 
   Box       Box furnaces are convenient furnaces to use. As the name implies, the furnace has a box shape and a box-shaped interior. The interior dimensions (10 to 50 cm per side) are much larger than a tube furnace, but the unit is often compact enough to sit on a benchtop. A door on the side permits quick and easy access to the interior. Several examples of box furnaces and their controllers are shown below. 
   Bottom Loading       Bottom loading furnaces load the sample or product to be treated through the bottom of the chamber via a platform elevator. 
   Top Loading       The product to be processed is loaded from the top. 
   Tube       A tube furnace is designed to heat a tube that is usually 50 to 100 cm in length and from 25 to 100 mm in diameter. Samples are placed inside the tube in ceramic or metal boats using a long push rod. The tube is surrounded by heating elements, which may also incorporate a thermocouple (a thermocouple can also be inserted down the tube if desired). 
   Bench / Cabinet       Cabinet or bench furnaces describe small batch equipment typically mounted on integral stands. Batch furnaces and ovens are typically suited for processing quantities of product in a single batch. 
   Continuous / Conveying       In general, conveyor units tend to be oriented toward automated production of greater quantities of small-to-medium-sized product. The type of conveyance system used depends on the product line, volume of work to be produced, and temperature to be obtained. 
   Walk-in / Truck-in       Walk-in or truck-in furnaces describe larger size batch equipment, typically with double doors and integral carts, shelves, etc. Batch furnaces are typically suited for processing larger quantities of product in a single batch. 
   Other       Other unlisted, specialized, or proprietary configuration. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Atmosphere & Control
   Controller Type:      Ovens may have either a single set point or a programmable controller to adjust temperature and temperature stability.
   Your choices are...         
   Single Set Point       Furnace has a specific temperature point to reach upon activation. 
   Programmable       Furnace may be programmed to reach different temperatures at different time intervals. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Heat Source / Transfer:       
   Your choices are...         
   Arc       An arc between graphite electrodes and the metal generates heat. Both carbon and alloy steels are produced in electric arc furnaces and scrap rather than molten metal is used as the base material. 
   Combustion       Furnaces using heat generated by combustion of gas, oil, biomass, waste products or other fuels.  The combusted gas may heat the material being processed directly or indirectly. 
   Electric / Resistance       Furnace heat source is powered by electricity - typically utilizing existing factory voltages. 
   Indirect / Contact / Conduction       Walls, tubes, jackets or discs are heated by steam, gas, thermal oil, or hot air. These heated elements transfer their heat to materials that come in contact with them via conduction. 
   Induction       A widely used process for the surface hardening of steel. The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. The core of the component remains unaffected by the treatment and its physical properties are those of the bar from which it was machined, whilst the hardness of the case can be within the range 37/58 Rc. Carbon and alloy steels with carbon content in the range 0.40/0.45% are most suitable for this process. 
   Infrared / Radiant       Furnaces using radiant heat generated by electric or gas fired infrared heaters.  Radiant heat units are useful for processing surfaces, flat products or web materials where clear line of sight can be provided. 
   Natural Gas       Furnace heat source is powered via natural gas. 
   Propane       Propane, sometimes indicated as liquefied petroleum (LP), is a catchall term for propane, butane, and mixtures of the two. It also includes propylene and butylene, which are sometimes included in blends, mostly outside the United States and Canada. In North America, propane is the most likely to be available in industrial quantities. Nearly any natural gas burner will operate on propane with little or no sacrifice in performance. 
   Oil       Furnace heat source is powered by oil heaters. 
   Other Fuel       Fuel other than natural gas, oil and propane used in combustion units. 
   RF / Microwave / Dielectric       In a radio frequency drying system an RF generator creates an alternating electric field between two electrodes. The material to be processed is conveyed or placed between the electrodes where the alternating energy causes polar molecules in the material to continuously reorient them to face opposite poles, much like the way bar magnets behave in an alternating magnetic field. The friction resulting from molecular movement causes the material to rapidly heat throughout its entire mass.  Areas in the material with greater moisture content heat up and dry faster. 
   Steam       Furnace heat source is steam, typically tapping off existing factory steam lines. 
   Other       Other unlisted or proprietary heat source. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

   Your choices are...         
   Aging       Describes a time-temperature-dependent change in the properties of certain alloys. 
   Annealing       Process annealing is used to treat work-hardened parts made out of low-carbon steels (< 0.25% carbon). This allows the parts to be soft enough to undergo further cold working without fracturing. 
   Baking       Heating to a low temperature in order to remove entrained gases. 
   Brazing / Soldering       Brazing is a method of joining metal parts together by fusing a layer of brass between the adjoining surfaces. A red heat is necessary and a flux is used to protect the metal from oxidation. 
   Burn-off       Removing cured paint, epoxies, and plastics from metal parts and other materials. 
   Curing       Using temperature to alter heated media by chemical or physical processing changes. 
   Drying       Uses temperature to remove moisture from object within oven / furnace.
