What does 25/T in this picture mean?
25/T is often used in the monetary or financial sector to represent a leverage or trading multiplier of 25 times. The specific details need to be interpreted in conjunction with the context of the image. .
Note: T is the maximum thickness of the heat-treated area
T stands for thickness. If the material has a thickness of 40 units, the speed should be 260*25/40 degrees per hour; if the thickness is less than 25 units, the speed is 260 degrees per hour
The standards are rather arbitrarily established and indeed hard to understand; the multiplication sign can be omitted, but it really shouldn’t be in this case. Writing it as 205*（25/T) makes it immediately clear
T – Material thickness； (Use capital letter T in GB 50235-97; use lowercase letter t in the 2010 version) 25 – Constant.
