Description
Technical field
The utility model relates to steel-making continuous casting technical field, in particular to a kind of slab automatic on-line quenching unit.
Background technique
In conventional continuous casting-heating furnace-Rolling Production process, the red heat slab of online production must be hung offline by overhead traveling crane
After being cooled to 500 DEG C or less to base library stacking, it can just return again to after roller-way is sent to heating furnace heating heating and be rolled.Hot charging heat
Sending technique is that the high temperature red heat slab produced of casting machine is directly sent to heating furnace heating heating by roller-way and rolled, which can
Greatly improve production efficiency, reduce casting billet surface oxidization burning loss, reduce heating time, can effectively save thermal energy, reduce process
Manufacturing cost.But red heat slab, usually at 800 DEG C or so, certain steel grade slabs are rolling after sending to heating furnace heating heating
Easily there is face crack in process light plate, greatly limits effective implementation of Process of Hot Transfering And Hot Charging.
Casting billet surface quenching technical can effectively avoid the generation of hot cracks.This method be conticaster to heating furnace it
Between roller-way region, using medium to casting billet surface carry out Cooling Quenching, its surface temperature is quickly reduced to two-phase section temperature
Below, it is ensured that complete transformation of the austenite to pearlite, bainite structure even martensitic structure.Since fast cool time is short,
Slab center portion thermal loss is few, and temperature is still higher.After rapid cooling, slab is admitted to heating furnace, in this transmission process, temperature
It spends higher center portion to be tempered casting billet surface, surface texture more tends to stablize, therefore high temperature modeling of slab during hot sending
Property is improved, and then prevents the generation of hot cracks.
Dimension, one kind can automatic identification slab position, automatically turn on water valve and guarantee slab press quenching during
Cooling will have Process of Hot Transfering And Hot Charging uniformly and to quenching unit and its process for quenching that the steam of generation is dealt carefully with
Effect is implemented to play the role of vital.And then casting billet surface oxidization burning loss is effectively reduced, reduces heating time, it can be effectively save
Thermal energy reduces process manufacturing cost.
Under normal circumstances in conventional continuous casting-heating furnace-Rolling Production process, to avoid generating hot-loading and hot-conveying crackle,
Method one are as follows: the red heat slab of online production must be hung offline after being cooled to 500 degree or less to base library stacking, Cai Nengzai by overhead traveling crane
Return roller table is rolled after sending to heating furnace heating heating.Method two are as follows: sling by overhead traveling crane high temperature slab designed
Roller-way feeding downstream process is again returned to after carrying out immersion cooling in pond.
But both the above method has the following deficiencies:
Method one: production cycle length, inefficiency, the big serious heat loss of slab temperature drop increase crane workload, increase
Process manufacturing cost is added.
Method two: slab cooling is violent, and casting blank deformation is caused to be bent, and cooling procedure generates steam and causes shadow to ambient enviroment
It rings, especially northern winter, too big the influences workshop top overhead traveling crane operating personnel's sight of fog, and steam is excessive easily leads to work around
Make environment icing.Reciprocal lifting operation increases crane workload, increases process manufacturing cost.
