Abstract
A quasi-conticasting and tandem-rolling technology for civil steel sections includes such steps as casting,ejection and rolling and features that the cast billet is immediately rolled without cooling. Its advantages include saving labour, less energy consumption and low cost.
Description
The invention belongs to steel casting and rolling technical field.
Present all kinds of steel rolling, except that the huge construction investment of needs and the good drawing-type continuous casting and rolling process for production of benefit and, generally bar mill all adopts the rolling production technology of casting → cooling → intensification.That is, after casting is finished, make it cool off the back ejection naturally, steel billet is delivered in the heating furnace of mill again, make steel billet rise to the technology that is rolled again behind the rolling warm area.Because steel billet heats up again after cooling off through nature in this technology, need to consume a large amount of energy, and increased the labour intensity of operation.
The objective of the invention is to develop a kind of more simple and convenient accurate casting and rolling process, make it promptly have the little advantage of common small section rolling mill production line investment; The energy consumption that has casting and rolling process again is little, the advantage of high efficiency, is suitable for producing conventional civilian (non-structure function) steel profile.
The objective of the invention is to realize by following design.
Continuous casting and rolling process for production of sectional steel materials, adopt casting → ejection → rolling → processing step.When the firm moulding of molten steel in the mold, promptly carry out the ejection operation, the mould base that is gone out should promptly be rolled on milling train.
After having adopted technology as above, just fast ejection was rolling when molten steel just formed surface cool, had avoided being warming up to rolling warm area again and a large amount of energy consumptions that need to drop into and the operation of working after the cooling ejection, greatly reduced the production cost of section bar.Its product can satisfy the function of general steel material for civil use (non-building structural steel).
Embodiment 1: with common life steel scrap be raw material after the intermediate frequency furnace melting in conduction of continuous casting mould machine (Chinese patent 97107648.0.97237494.0) top casting, mold is a φ 50mm garden base.Strand is chilled to 1100 ℃ of (this moment, steel billet separated with mould surface) ejection, is φ 18mm garden cylindricality steel bar in the reciprocal rolling postforming of lap siding milling train, is used to make the door and window guard rail.
Embodiment 2: other condition is with example 1, and mold is a φ 40mm garden base, and it is rolling that strand is cooled to 1000 ℃ of beginning ejection, is shaped to the steel bar of the equilateral triangle tee section of outer garden diameter 18mm.
Embodiment 3: other condition is with example 1.Mold is the slab of 1000 * 30 * 20mm.1050 ℃ of ejection temperature, ejection is rolling, is shaped to the slab of thickness 3mm.
Adopt technology of the present invention, except that can the section bar of rolling routine, also can be used for the production of product (as tup, simple farm implements etc.) more widely, in actual production, the ejection temperature has corresponding correction with the physical dimension of mould base, the component difference of steelmaking feed.
Claims (2)
1, a kind of continuous casting and rolling process for production of sectional steel materials, adopt casting → ejection → rolling → processing step.It is characterized in that when the firm moulding of molten steel in the mold, promptly carry out the ejection operation, the mould base that is gone out is rolled immediately on milling train.
2, continuous casting and rolling process for production of sectional steel materials according to claim 1 is characterized in that, for common iron, its ejection temperature is advisable at 1000～1100 ℃.
