The carburization of ethylene pyrolysis tubes is characterized using hardness, x-ray diffraction (XRD), scanning electron microscopy (SEM) and optical microscopy.
Dec 03, 2015 · Heat-Treat Rack Material Selection Based on Thermal Performance. The selection of rack-material composition is typically dictated by the operating conditions of the specific heat-treating process involved.  The furnace operator must select materials capable of performing within these conditions, and the decision often balances performance against purchase price.
There are 517 vertical melting furnace suppliers, mainly located in Asia. The top supplying country or region is China, which supply of vertical melting furnace respectively. Vertical melting furnace products are most popular in Domestic Market, Southeast Asia, and Eastern Europe.
Horizontal, Vertical, Tilting, Rotating, and Vacuum Tube Furnaces from Sentro Tech. Sentro Tech is a leading manufacturer of custom high-temperature tubular furnaces. We manufacture both horizontal and vertical tube furnaces, some of which come equipped with tilting, rotating, and vacuum functionality.
Sep 24, 2013 · Decarburization occurs when carbon atoms at the steel surface interact with the furnace atmosphere and are removed from the steel as a gaseous phase (1-8). Carbon from the interior will then diffuse towards the surface, that is, carbon diffuses from a region of high concentration to a region of low concentration to continue the decarburization process and establish the maximum depth of decarburization (MAD).
Carburizing, carburising, or carburization is a heat treatment process in which iron or steel absorbs carbon liberated when the metal is heated in the presence of a carbon bearing material, such as charcoal or carbon monoxide, with the intent of making the metal harder.
Diffusion furnaces are tube furnaces that are used in manufacturing semiconductors, photovoltaic products & led displays which require high temperature and moderate vacuum medium. Diffusion furnace process includes dopant diffusion, thermal oxide growth and doping.
A cased vertical evaporator coil is used with furnaces in the upflow or downflow position. The coils have physical dimensions to correspond to the various widths of furnaces available on our website and are designed to fit correctly with the furnace.
The VF1000 is a full performance vertical furnace. The capacity of this furnace has been kept small, because research customers require small capacity in most cases. Therefore this system has been developed as a mini batch furnace for 25 wafers (standard) or 50 wafers (option) capacity.
charged into a furnace, which normally has a temperature of 800 – 850 °C (1472 – 1562 °F) for carbonitriding and about 900 – 950 °C (1652 – 1742 °F) for gas carburizing.

combustion, reduction and carburization. The briquette moves down slowly, starts melting in a cohesive zone and trickles in the form of hot metal and molten slag in the lower part of the furnace. In contrast, cold air blasted through tuyeres flows up through packed materials. For the simulation of this reactor, three key parameters must
Dec 01, 2018 · Vacuum furnace designs used for the brazing process can be either horizontal or vertical in design and offer the following technical advantages: The process permits brazing of complex, dense assemblies with blind passages that would be almost impossible to braze and adequately clean using atmospheric flux brazing techniques.
Due to the high atomic mobility of carbon in these layers, it penetrates into the alloy, causing precipitation into the tube wall , , . The level of carburization can be determined by the volumetric fraction of chromium carbides formed and by their distribution within the thickness of the walls of the tube.
Carburizing is basically a case hardening technique that involves the addition of carbon on top of a metal surface layer to improve the metal properties. The following article explains the basics of the carburizing process as well as provides more details about the four current methods of carburizing metals, including the popular gas carburizing.
Horizontal Double Chamber Vacuum Carburizing Furnace Functional Characteristics: Horizontal double chamber structure, one carburizing chamber and one quenching chamber, quenching medium can be selected according to actual conditions.
