In the atmosphere loop, the controller uses the carbon potential calculation based on the known oxygen reading to increase the carbon potential by allowing enrichment gas (ie methane) to enter the furnace. Conversely, to decrease the carbon potential, controlled air is introduced into the furnace.
2018612It seems ironic that the one constant in atmosphere heat treating is that the composition of the furnace atmosphere is always changing. As such, we must use measurement and control devices to ensure the proper atmosphere composition necessary to achieve the desired metallurgical quality and mechanical/physical properties throughout the workload.
On the other hand, vacuum batch sintering furnaces, as offered by a number of commercial suppliers, allow for excellent control of the debinding and sintering process. The aforementioned limitations, in terms of geometrical distortion and chemical composition of the finished MIM parts, can be contained.
CM Furnaces has developed a line of "hot wall" batch furnaces with complete process control for temperature and atmosphere without the added expense of "cold wall" vacuum construction. Offered in two temperature ranges and several sizes, these furnaces meet virtually any application requirement where vacuum is not absolutely necessary.
Hydrogen Atmosphere Furnace . High Temperature Hydrogen Atmosphere Furnace, 1600℃ Hydrogen Gas Controlled Furnace . Hydrogen atmosphere furnace is specially designed for sintering or annealing materials in hydrogen or inert gas environment. The highest temperature can reach to 1700℃.
A Typical Furnace Control for Temperature & Carbon Atmosphere. Figure 1 shows a typical Carbon Master configuration. Using a UP750 (or UT750) Carbon Master Controller, both the carbon atmosphere and the furnace temperature are controlled in one controller. "IN2" is the furnace temperature input and "A02" is the furnace temperature control signal.
The VCAP furnace is designed for Induction Melting a solid charge in an air atmosphere (or vacuum), with final degassing stage under vacuum. The final pouring of the metal is performed in air or under protective atmosphere of inert gas. Configuration is based on the Inductotherm brand of steel shell induction furnaces which are fully adapted
Furnace is "Atmosphere Capable" and designed for Aluminum Oxide Sand. Also included is 60" Diameter x 72" Deep (ID) Oil Quench Tank, and 100 KVA Tap-Changing Transformer. Controls: Wall-Mounted Control Panel with Honeywell 12" Strip Chart Recorder/Controller, and Honeywell 3000 Series Digital High Limit.
Controlled Atmosphere Furnaces. Deltech electric controlled atmosphere furnaces allow for sample and product processing in air, inert atmospheres, and under positive pressures. Controlled atmosphere furnaces provide a sealed workspace in which gases can be introduced.

Controlled atmosphere natural gas furnaces enable manufacturers to thermally treat products or materials to refractory temperatures with exceptional selection of the internal atmospheric composition. This article will outline the capacities of one of the exceptional natural gas firing furnaces available from Thermcraft in more detail:
A Muffle Furnace is a Continuous Furnace that allows continuous processing of small to medium sized parts in a Controlled Atmosphere. Most commonly produced as a metal alloy tunnel, either with doors or simple isolation gas seals at the ends, muffles furnaces have several different means of transport of product through the furnace, and can be designed to use either electricity or fuel gas
