Carburising Fluid Rx is basically pit-pot type fluid used for hardening / case carburising /carbonitriding of various components made of steel such as railway part, auto parts, gears, precision turned components, construction machinery parts and any other component needing hardening. By controlling the rate of flow by various means, neutral or carburising gaseous atmosphere can be created in the retort for carrying out processes such as annealing, carburising and carbonitriding. The fluid is generally known as carburising fluid, because of its more popular use for carburising or casing of steel.
Carburising Fluid RX has been specially formulated for use in the single fluid drip process. This process has certain economic and practical advantages in the comparison with other known processes of Carburising.
Carburising Fluid RX is used in the heat treatment industry for the carburising of low carbon steels.
Carburising with Carburising Fluid Rx is carried out in electrically heated pit type furnaces, which are usually designed for this type of a carburising operation. The carburised case depth depends on the time and temperature of the process.
PRINCIPLES OF USE
Carburising Fluid Rx gas carburising fluid is drip fed in retort type furnaces, at carburising temperature (above 800° C). It cracks in the furnace to form a gas having uniformly high carbon content. The atomic carbon available after a series of chemical reactions of this gas is absorted by the components to obtain a skin with high carbon content. The gas is chemically constant and gives duplicity of performance, batch after batch, unlike the unsaturated hydro-carbons sometimes used for this kind of operation. The Carburising Fluid Rx is so balanced in its composition that the maximum carbon potential which the gas acquires does not exceed more than adequate.
The Carburising Fluid Rx fluid meets the needs of most of the engineering components which require 0.75 to 0.80% carbon case.
