Abstract
The invention relates to a cooling device for a vertical bright annealing furnace. The device comprises a radiation-type cooling zone and a plurality of sections of cooling ejectors, wherein each cooling ejector comprises a cooling channel, a heat exchanger and an ejecting fan; the lower end part of the cooling channel is connected with one end of the heat exchanger; the upper end part of the cooling channel is connected with one end of the ejecting fan; the other end of the heat exchanger is connected with the other end of the ejecting fan; the ejecting fan symmetrically ejects hydrogen to wash strip steel and is matched with the heat exchanger to cyclically cool hot hydrogen; graphite rollers are arranged inside the cooling channel; two graphite rollers are arranged in an externally tangent mode; and a strip steel passing line passes through a tangent point of the two graphite rollers. Airflow in the cooling ejectors is adjustable, and the surface of the cooled strip steel has higher finish and flatness.
Description
Technical field
The present invention relates to a kind of refrigerating unit of vertical bright annealing oven.
Background technology
Vertical bright annealing oven is the heat-treatment of annealing equipment that is applicable to high alloy Cr (ferrite Cr steel alloy and martensite Cr steel alloy) and CrNi (austenite CrNi steel alloy), is applicable to the annealing of band steel.
In the steel alloy clean annealing process, must overcome following difficulty: the element Cr that contains in the steel alloy, Mn, and trace additives Ti, Si, Al etc. have higher oxygen affinity, thereby form oxide compound failure surface smooth finish easily.For fear of the formation of such oxide compound, this just requires the annealing temperature height, and low (dew point is lower than-60 ℃) of dew point and employed protective atmosphere have stronger reductibility when annealing than iron.
Alloy band steel in annealing, except avoiding oxidation, in order to obtain the level and smooth surface of light, also require the band steel by the time avoid physical abuse.For this reason, the band steel will accurately guide in the whole service process, first centering enter inlet, turn to the cooling channel centrally, in the backhaul passage, derive at last.
For being with steel as thin as a wafer, because bigger band steel flakiness ratio, the band steel very easily is out of shape (wave, eaves gutter shape, depression etc.).Scope is at the steel of band as thin as a wafer of 0.03-0.1mm, can only be in vertical heater clean annealing.This is a problem that is difficult to overcome in the metal heat treatmet field always.Because require strip tension can accurately be adjusted to minimum level for the annealing with steel as thin as a wafer, and the travelling speed and the furnace of band steel must be mated proper.The band steel is through after the body of heater heating, must cool off gradually and requires the air-flow in the shower cooler adjustable it.
Summary of the invention
The object of the present invention is to provide a kind of refrigerating unit of vertical bright annealing oven.
In order to reach above purpose, the scheme that the present invention adopts is:
A kind of refrigerating unit of vertical annealing furnace, it is characterized in that: described refrigerating unit comprises: the radial pattern cooling zone, the plurality of sections cooling injection device that is connected with described radial pattern cooling zone, described cooling injection device comprises the cooling channel, at this both sides, cooling channel symmetrically arranged heat exchanger of difference and injection blower fan, the bottom of described cooling channel is connected with an end of described heat exchanger, the upper end of described cooling channel is connected with an end of described injection blower fan, the other end of described heat exchanger is connected with the other end of described injection blower fan, the symmetric ejection hydrogen of described injection blower fan washes away the band steel of process, and cooperate described heat exchanger, the cooling that circulates to hot hydrogen, be provided with graphite roller in the described cooling channel, described graphite roller is provided with two, and mutually circumscribed setting, the band steel passes through from two described graphite roller point of contacts by line.
Preferably, described heat exchanger is provided with shut-off valve, and this shut-off valve can be regulated the aperture of described thermo cycler, the circular flow of pilot-gas.
Preferably, described graphite roller can be regulated by motor, controls its horizontal mobile retainer belt steel and vertically passes through.
