20141013When the Role of the Furnace Atmosphere is to be Chemically Active. A low-carbon steel AISI 12L14 retaining ring is gas carbonitrided at 845°C (1550°F) in an endothermic gas atmosphere enriched with natural gas and ammonia to provide a source of both carbon and nitrogen for absorption into the surface of this 0.14% carbon steel.
2.Good vacuum flange sealing to make sure no leakage. 3.The furnace chamber is ceramic fiber with excellent thermal insulation. 4.The temperature is controlled by precision SCR(Silicon Controlled Rectifier) with accuracy +/-1 C and 30 segments programmable control; 5.The fast rate of temperature increasing and decreasing
High vacuum furnace is widely used in the heat treatment of metallic material or ceramic parts in low or high vacuum, especially used in the vacuum Sintering and Annealing of the materials like stainless steel, high temperature alloy, hard alloy and nonferrous metal in reducibility or protective atmosphere.
Description: -treat large and heavy welded fabrications such as gear blanks, oil drill pipe, drive shafts, and similar type products. The product car also serves as the floor in the furnace and uses various mechanisms to seal the car to the furnace.
AVS Vacuum Debinding/Sintering Furnace. This is a horizontal graphite vacuum debinding sintering furnace for steel MIM parts completely rebuilt from top to bottom by AVS in 2010. Working volume - approximately 18 cubic feet, 28" wide x 26" high x 42" long graphite retort, 1500# capacity.
Hydrogen furnace also known as hydrogen furnace. To pass hydrogen or hydrogen, nitrogen mixture gas (hydrogen content >5%) as a protective atmosphere heating equipment. There are vertical and horizontal types. Heating element usually adopt molybdenum wire melting point is 2630 ℃ (mo), shell for metal, maintain good air tightness.
The furnace has good sealing performance, effectively avoiding oxidation and rust of the workpiece surface during annealing, and improving processing quality; The holding furnace body can be moved backwards. After the annealing is completed, the cooling rate is increased while maintaining the vacuum state.
19851112One significant aspect and feature of the present invention is a process for hot isostatic pressing of ferrite material providing superior ferrite which can be processed into desired geometrical configurations with significantly less likelihood of chipping as can be a problem with previous fabrication methods.
