Description
Technical field
The present invention relates to the heat recovery technology field of steel-making continuous casting base more particularly to a kind of continuous casting billet heat recovery
Device.
Background technique
Most of waste heat of current continuous casting billet is without recycling, mainly since the recycling of existing continuous casting billet waste heat is set
It is standby to be all made of traditional radiant type heat exchange mode, and this heat transfer type is when temperature is lower than 1000 DEG C, heat transfer coefficient is very low, with
Cause equipment investment return rate undesirable, most occasions are unworthy coming into operation.
Summary of the invention
In order to solve the above technical problems, structure is simple, energy the present invention provides a kind of continuous casting billet waste heat recovery device
Enough waste heats for utilizing continuous casting billet to greatest extent, it is energy saving, while high temperature damage is reduced, so as to improve working environment.
The technical scheme adopted by the invention is as follows: a kind of continuous casting billet waste heat recovery device, including waste heat boiler are heated
The conveying device for being used to convey continuous casting billet on the downside of waste heat boiler heating surface is arranged in face, further includes drum, and waste heat boiler is heated
The one end in face is equipped with upper header group, and upper header group connects drum by riser culverts, and drum is separately connected heat by declining pipeline
The tail end of the head end of water-circulating pump and bypass line, hot water circulating pump and bypass line is connected by flowmeter with lower collecting box group
It connects, lower collecting box group is connected to each heat pipe of waste heat boiler heating surface, between the downside and continuous casting billet of waste heat boiler heating surface
Equipped with easy-to-dismount flexible Heat Conduction Material.
As a preferred technical solution of the invention, setting is interlocked between the hot water circulating pump and flowmeter.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
Structure is simple, can utilize the waste heat of continuous casting billet to greatest extent, energy saving, while reducing high temperature damage, from
And improve working environment.
Detailed description of the invention

Specific embodiment
In order to better understand the above technical scheme, below in conjunction with attached drawing and specific embodiment to above-mentioned technology
Scheme is described in detail.
A kind of continuous casting billet waste heat recovery device described in the present embodiment, including waste heat boiler heating surface 7 are arranged remaining
The conveying device 10 for being used to convey continuous casting billet 9 of 7 downside of heat boiler heating surface, further includes drum 1, waste heat boiler heating surface 7
One end is equipped with upper header group 11, and upper header group 11 connects drum 1 by riser culverts 12, and drum 1 is connected respectively by declining pipeline 2
Connect the head end of hot water circulating pump 3 and bypass line 4, the tail end of hot water circulating pump 3 and bypass line 4 passes through flowmeter 5 and the second line of a couplet
Case group 6 is connected, and lower collecting box group 6 is connected to each heat pipe of waste heat boiler heating surface 7, the downside of waste heat boiler heating surface 7
Easy-to-dismount flexible Heat Conduction Material 8 is equipped between continuous casting billet 9, it and the direct thermal contact conductance of continuous casting billet, heat transfer coefficient is bigger, mentions
High heat exchange efficiency, reduces equipment size.
Wherein, in the present embodiment, setting is interlocked between the hot water circulating pump 3 and flowmeter 4, is set when flow reaches
When definite value A, water pump is closed, and when flow is lower than setting value B, water pump is opened.Circulatory system when both ensure that boiler startup in this way
Foundation, and can equipment operate normally when reduce the unnecessary power consumption of water pump.
When equipment comes into operation, hot water circulating pump is first opened, makes to reach setting value B by the flow of flowmeter 5, starts continuous casting billet
Conveying device, continuous casting billet 9 pass sequentially through heating surface lower end, and waste heat a part of continuous casting billet 9, which radiates, passes to heating surface 7, and one
Divide and waste heat boiler heating surface 7 is conducted to by flexible Heat Conduction Material 8, waste heat boiler heating surface 7 is absorbing the waste heat of continuous casting billet 9
Afterwards, steam water interface is generated, upper header group 11 is pooled to, drum 1 is returned to by tedge 12 and carries out steam-water separation, steam is for steaming
Vapour user uses, and saturated water continuation is recycled in system, and the water of missing is supplemented by the feed water system of boiler.
As circulation is established, the continuous increase of Natural Circulation power is when the flow by flowmeter 5 reaches setting value A
Control module of uniting issues the motor speed of instruction adjustment hot water circulating pump until closing.When there is no continuous casting billet 9 to pass through, follow naturally
Ring power dropping is also declined therewith by the flow of flowmeter 5, and when being down to setting value B, when high-temperature flue gas, system controls mould
Block issues instruction and reopens hot water circulating pump.
The main distinction of the present invention and existing waste heat recovery device is: increasing between heating surface and continuous casting billet 9
Flexible Heat Conduction Material 8, using efficient conduction heat transfer mode；It is used between flexible Heat Conduction Material 8 and waste heat boiler heating surface 7
Quick detachable bolt form, easy access replacement.Bypass line 4 is increased, this pipeline is equipped with check-valves, it only allows to be saturated
Water flows in a direction indicated by the arrow, and saturated water flows back after preventing water pump from opening；The flowmeter 5 for increasing down-comer road, is allowed to
It is interlocked with hot water circulating pump motor inverter.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, according to the technical essence of the invention
Any simple modification, equivalent change and modification to the above embodiments, all of which are still within the scope of the technical scheme of the invention.
