Description
Technical field
The present invention relates to metallurgical technology fields, add in particular to a kind of heating furnace heating means and a kind of heating furnace
Hot systems.
Background technology
CSP (compact strip plant) means close-coupled output strip line, refers to a forward position on current metallurgical boundary
Technology has the advantages such as flow is compact, small investment, low energy consumption.CSP technological processes are generally：Vertical bending type thin slab conticaster →
The rack finish rolling of swinging shears → roller hearth type heating furnace → high-pressure water descaler → vertical miller → 7 → section cooling → downcoiler
→ steel coil transportation line → storage.
CSP flow roller hearth type heating furnaces are generally divided into bringing-up section, soaking zone, soaking zone.Every section of burner form and burning
Efficiency is not quite similar, and bringing-up section burner is big, heating efficiency is strong；Soaking zone and soaking zone burner is small, heating efficiency is small.Due to CSP
The particularity of production line, roller hearth type heating furnace accept the continuous casting working procedure of upstream, downstream milling train process, heating furnace ensure plus
While thermal effect, it is also necessary to buffer rhythm, for the online roll change of milling train, unload volume, handle some minor accidents etc..Therefore, maximum
The efficiency of heating surface of the promotion bringing-up section of limit not only can quickly improve heating temperature using the big characteristic of bringing-up section burner, but also can be with
The buffer time in stove is kept to greatest extent
CSP heating furnaces are to ensure there is corresponding buffer time in stove, therefore in the prior art, steel billet is equipped in stove and fixes
Acceleration point, acceleration point is exactly after steel billet enters heating furnace with teeming speed in stove, starts the position accelerated, the effect of acceleration point be
Under the premise of ensureing billet heating temperature, the buffer time of heating furnace is adjusted, the speed that steel billet enters heating furnace is the casting of casting machine
Speed, the speed that steel billet leaves heating furnace are the entrance velocities of milling train, and the two speed is inconsistent.But by the shadow of upstream and downstream process
It rings, the charging temperature of steel billet can fluctuate up and down, and after steel billet accelerates in fixed acceleration point, the tapping temperature of steel billet temperature can not reach
To requirement.
