Silicon Carbide Radiant Tube (CRT) Conv. - Gas to Gas (Heat Treating)
Purpose This tool allows you to estimate the simple payback on conversion to
advanced silicon carbide radiant tubes (CRTs) in place of metal alloy and/or mullite
tubes in any atmosphere heat treating furnace.
Note: For simplicity the payback calculator focuses on extended tube life and
increased furnace productivity only. Additional benefits not captured here include:
labor cost savings, improved furnace heat-up time, and energy cost savings.
the calculator, simply put numbers in every blank white field. Be careful not
to skip any fields, which may throw off the results, and to enter only numbers
(no "$" signs etc.). When you have finished filling out the fields on
a page, click the "Continue Calculating" button.
