Description
Technical field
The present invention relates to equipment of hot rolling, more particularly to a kind of mobile hot rolling heat preservation hot processing unit.
Background technology
The production of cold rolling super-high strength steel is primarily present strip length and the big problem of width direction performance inconsistency, and cold rolling is caused to be given birth to
Occur roll-force big ups and downs, cold rolling finished product thickness super tolerance standard when production, the rolling that this had both influenced cold rolling acid Continuous mill train is steady
It is qualitative, and seriously affect cold rolling super-high strength steel lumber recovery.
Traditional hot rolling producing line only completes the conveying of coil of strip in steel coil transportation after the completion of batching, if coil of strip needs
The treatment process such as slow cooling, annealing are kept the temperature, need that the producing lines such as special holding pit, holding furnace, bell furnace, heat treatment are arranged.Tool
There is the features such as big investment, high energy consumption, transportation cost is big, lumber recovery is low.Especially high-strength steel kind, above-mentioned technique is due to timeliness
Reason technological effect can not reach ideal state.
Now domestic and international mainstream steel mill mostly uses offline holding pit, insulated wall or holding furnace to carry out slow cooling to high-strength steel, move back
Fire processing further makes band coil of strip postcooling uniform, achievees the purpose that improve performance inconsistency and discharges internal stress.Certain at this stage
A little companies make some interim development and application to mobile hot rolling annealing regulation device, exist during use and much ask
Topic.
(1) most outstanding problem existing for rolling line attemperator is to enter the interval time mistake of attemperator after strip coiling
Long, the metallographic structure transformation of strip to be had occurred and that or completes, and offline slow cooling mode cannot expire the effect of hot rolling performance improvement
The quality requirements of sufficient high-strength steel.Hot rolling, which is placed into insulation cover, needs 20~30 minutes handling time, the air cooling time mistake of coil of strip
It is long, influence heat insulation effect and material property.
(2) such attemperator increases the cost that the producing lines such as special holding pit, holding furnace, bell furnace, heat treatment are arranged
The normal production of universal higher and transformation process influence long in time limit.And it asks there are heat insulation effect (temperature drop rate is very fast) is bad
Topic.
(3) such form insulation cover is essentially all off-line mode (static be placed on of attemperator batches platform), coil of strip
Transport handling upsets the normal rhythm of production of producing line.The performance of steel rolling production-line production capacity is influenced, practical mass production difficulty is big.
(4) at this stage in there is the insulation cover of certain companies exploitation to only exist heat insulation effect in form, not due to bottom structure
It can be fully sealed, coil of strip heat insulation effect is bad.
" a kind of Carrier roller tray type metal belt coil transport device " disclosed in Chinese patent CN201210338335 comprising fortune
Defeated chain pallet takes steel coil and carries out upper volume transport after finishing.The device is only independent steel coil transportation fixed saddle.It cannot be into
Row in transit keeps the temperature coil of strip online.
Disclosed in Chinese patent CN201710853613.3 " annealing device is kept the temperature online " comprising：Only exist heat preservation effect
Fruit, since bottom structure cannot be fully sealed, coil of strip heat insulation effect is bad.
Disclosed in Japan Patent JP1985110816 (A) " single type insulation cover " comprising：Single type insulation cover, it is a kind of
Roller transport chain structure form, can only accomplish coil of strip insulation effect.
Disclosed in Japan Patent JP2010094710 (A) " tunnel type insulation cover " comprising：Increase and special heat preservation is set
The normal production of generally high cost and transformation process influence long in time limit of the producing lines such as hole.

A small amount of steam is adhered on surface in the process.To ensure equipment safety and improving coil of strip quality, before being passed through protective gas to insulation cover
Exclude high-temperature gas.
Insulation cover outer layer is high-strength steel gusset, and insulation cover needs frequently lifting to ensure lifting intensity.Outside is Special temperature resistant
Steel.The upper thermal insulation material of centre covering, penetralia lays high temperature resistant stainless steel plate after intermediate anchor nail is fixed.To ensure that the later stage hangs
Fortune increases lifting sucker on insulation cover top.Simultaneously because coil of strip property and type relationship, insulation cover can be fabricated to remaining shape
Formula (square thermal-insulation cover, round heat insulation cover structure), the raising of coil of strip performance is more favorable for after changing temperature field structure.
Electric heater unit, which makes insulation cover not only, can realize to coils of hot-rolled steel residual temperature using slow cooling is realized, simultaneously for certain
Special rolling-mill section can carry out reheating processing, realize that double tempering improves coil of strip performance crystal grain thinning.
Infomation detection sending module records steel roll temperature in insulation cover.It is examined above with increase in insulation cover
Survey element, PLC system and wireless launcher will keep the temperature information in Zhao and identify.It is implanted into thermocouple inside insulation cover, surveys
0~1100 degree of warm range, the temperature change for detecting insulation cover inner air.
In order to by data transfers such as air themperatures in insulation cover to ground-based server, while by related coil of strip data information
It is transferred to downstream.It is borrowed wirelessly and electrical storage device, is realized by installing Wireless remote control case in original heat preservation cover outer surface
The functions such as insulation cover movable type thermometric samples, data wireless transmission, and logistics information write-in is read.
Beneficial effects of the present invention：
Semicircular structure design of the present invention has good lightweight construction, heat insulation effect, coil of strip handling facility, the degree of automation
