Carbon Fiber

1. Industry Demand

Carbon fiber production including spinning cooling, pre-oxidation furnace waste heat recovery and carbonization furnace cooling is highly temperature-sensitive, with working temperatures ranging from normal temperature up to 1500℃. Heat exchangers need ultra-precise temperature control, high temperature resistance and outstanding heat transfer efficiency to eliminate fiber defects such as uneven diameter and insufficient strength, while realizing energy saving via waste heat recovery and stable continuous production.

2. Core Working Stations

Core working scenarios cover precise constant-temperature spinning cooling, flue gas waste heat recovery of pre-oxidation furnaces, ultra-high temperature stabilization for carbonization furnaces, and intensive heat transfer for extreme temperatures above 1200℃. It serves the full carbon fiber production line for stable product quality, lower energy consumption and long-cycle non-stop operation.
