Description
Technical field
The invention belongs to steel technical field, is related to a kind of generous specification slab grade transition production technology.
Background technology
Since slab production order is scattered, cause the slab production steel grade trade mark more；Small order steel grade organization of production is needed in list
Bag production, causes continuous casting of high cost；Meanwhile slab steel grade list stove even pours, the plate produced under unstable state production status is rejected
Base, normal slab recovery rate only 50%, reduces continuous casting operating rate and adds production cost.
By carrying out system high efficiency integration to plate steel grade, grade transition scope is expanded as core using optimization, is being ensured
On the premise of continuous casting billet quality, using identical crystallizer cooling, secondary cooling, slighter compress setup parameter, grade transition is realized,
Simplified organization of production can be reached, improve continuous cast crystallizer number in plate list, improving production efficiency, improves slab production capacity, reduces life
Produce the purpose of cost.
The content of the invention
The technical problems to be solved by the invention are to carry out system high efficiency integration to plate steel grade, optimize grade transition
Continuous casting manufacturing technique and the science judgement for even pouring section slab, the shortcoming existing in the prior art for more than, proposes a kind of generous rule
Panel base grade transition production technology, this is simple for process, reaches simplified organization of production, improves continuous cast crystallizer number, lifting
Production efficiency, improves slab production capacity, reduces production cost.
For a kind of generous specification slab grade transition production technology, poured during even pouring using same tundish
Two steel grades of A, B for being divided to and differing greatly are formed, are comprised the following steps：
（1）Order is poured by definite company
Determined even to pour order according to the carbon content of two steel grades of A, B or alloying element content, that is, determine previous big bag and latter big
Bag；
（2）Ladle, which is opened, to be poured
The molten steel wrapped greatly is injected into tundish so that middle Baogang's water level is stablized, and realizes continuous casting continuous production；
（3）Middle bag is mixed to be poured
The molten steel of previous big bag is injected into tundish, at previous big bag pouring molten steel latter stage, is injected in tundish latter
Big Baogang water, by A steel grades, B steel grade molten steel transition Composition Controls, that is, adds C steel grades and adjusts, realize that A, B steel grade even pour；
（4）Throwing
Metal in Tundish injection crystallizer, the crystallized device cooling of molten steel, secondary cooling, bending, aligning, slighter compress technology controlling and process,
Produce up-to-standard blank；
（5）It is mixed to pour blank judgement
A steel grades, B steel grade transition, which mix, pours to obtain changeover portion blank, is identified according to blank decision-making system, with reference to grade transition
Changeover portion blank disposal principle is judged；Changeover portion blank is rolled after judgement, and steel plate inspection, field trash are carried out after rolling
Check and evaluation.
The technical solution that further limits of the present invention as：
In foregoing generous specification slab grade transition production technology, step（1）Middle carbon content or conjunction according to two steel grades of A, B

Kind is positioned in previous big bag, and rear steel grade of the cast without Nb, Mo, V, Cr, Ni, Cu, B alloying element is positioned in latter
Big bag；
A, two kinds of steel grades of B include the high steel grade of the alloying element containing Nb, Mo, V, Cr, Ni, Cu, B with containing Nb, Mo, V, Cr, Ni,
The low steel grade of Cu, B alloying element, when even pouring, cast order should be according to first cast is containing Nb, Mo, V, Cr, Ni, Cu, B alloy member
The high steel grade of element is positioned in previous big bag, and pouring into a mould the low steel grade of the alloying element containing Nb, Mo, V, Cr, Ni, Cu, B afterwards, it is set
In latter big bag.
In foregoing generous specification slab grade transition production technology, step（1）The middle carbon content according to two steel grades of A, B
Or alloying element content determines even to pour order, including：
A, vacuum steel and antivacuum steel in two kinds of steel grades of B, when even pouring, cast order should be according to first vacuum steel is positioned in
Previous big bag, rear antivacuum steel are positioned in latter big bag.
In foregoing generous specification slab grade transition production technology, step（3）When company pours, A, B steel grade are identical steel grade
During serial different steel grade, C, P, S, Alt element are by where steel grade in the C steel grades that when A steel grades, B steel grade molten steel transition adds
Row grade transition component requirements are controlled, and other elements are still controlled according to steel grade quality planning or steel grade regulatory requirements
System.
In foregoing generous specification slab grade transition production technology, step（3）When company pours, A, B steel grade are to differ steel
During kind of serial different steel grade, the C steel grades that when A steel grades, B steel grade molten steel transition adds pour steel grades requirement control according to each company
System, grade transition changeover portion blank carry out evaluation disposal, and the component outside grade transition changeover portion is still according to steel grade quality
Plan or code regulation judge.
In foregoing generous specification slab grade transition production technology, connect for the dissimilar steel for having the steel grade of carbon equivalent requirement
Pour, the carbon equivalent of previous big bag and latter big bag performs most tight requirement, otherwise all carries out evaluation disposal.
In foregoing generous specification slab grade transition production technology, changeover portion during identical Grades Series grade transition
Blank disposes principle：
When transition steel grade C steel grades can correspond with the composition quality plan or the requirement of code regulation of A, B steel grade at the same time, point
Do not judge according to the quality planning of raw steel kind or code regulation；
When transition steel grade C steel grades cannot correspond with the composition quality plan or the requirement of code regulation of A, B steel grade at the same time
Carry out evaluation disposal.
In foregoing generous specification slab grade transition production technology, transition during Grades Series grade transition is differed
Section blank carries out evaluation disposal.
In foregoing generous specification slab grade transition production technology, generation material is performed according to the principle of replacement of low quality materials by high quality materials during rolling
Production.
The beneficial effects of the invention are as follows：
The present invention carries out system high efficiency integration to plate steel grade, combs production steel grades, is ensureing the premise of continuous casting billet quality
Under, using identical crystallizer cooling, secondary cooling, slighter compress setup parameter, realize grade transition, simplified production can be reached
Tissue, improves continuous cast crystallizer number in plate list, and improving production efficiency, ensures grade transition transition blank quality, improves slab
Production capacity, reduces the purpose of production cost, is particularly suitable for Heavy Plate Production enterprise, has good promotional value.
