Diffusion is contacted with the strip still in high temperature positioned at cold section eventually；After the water vapour of high concentration is contacted with hot strip steel, it may occur that one
The chemical reaction of series, causes the low-level oxidation of belt steel surface, yellow mottling occurs from belt steel surface is macroscopically rendered as, cause to produce
Quality degrades, shortened shelf life, leads to that quality objection occurs；And when producing thin gauge strip or machine, yield is relatively low, production
Raw water vapour amount is less, and the discharge wind turbine of constant power still keeps equal-wattage to discharge, and watch-quench tank groove body top is caused to go out
Existing lower negative pressure value, takes a large amount of protective gas away again out of annealing furnace, causes the waste of the protective gas energy.
Currently, the discharge of steam to continuous annealing furnace watch-quench tank only leans on the discharge wind turbine of rated power to discharge, without automatic
Tracking and control device, efficiency is low, and controllability is not strong, can not real-time tracking water vapour whether be all discharged, easy to produce band
Steel surface mass defect cannot be satisfied Large Scale and Continuous annealing furnace needs of production.
