On the other hand, produce continuous casting steel billet and mainly adopt fourplatemold in prior art, mold shape is rectangle or the rectangle with chamfering.No matter which kind of type crystallizer, its side is all vertical below with upper.When following process composite blank, need 2 sides all to process, consume a large amount of time and higher processing charges, cause a large amount of wastes, also affect lumber recovery simultaneously.
Application number is that the Chinese patent of 201210201520.X discloses a kind of combined type sheet billet continuous casting chamber crystallizer narrow-surface copper.Application number be 201120379974.7 Chinese patent disclose a kind of slab caster fourplatemold copper coin of improvement.In two patents, crystallizer have employed chamfering copper coin equally, and the continuous casting billet produced is applied to composite billet and adds and can produce larger milling amount man-hour, and processed complex, product lumber recovery are low.
Application number 201110434576.5 discloses a kind of fourplatemold, and its section is rectangle, and the continuous casting billet produced is applied to composite billet and adds the larger milling amount of man-hour requirement, and the clad steel plate of Rolling Production can produce larger twin drum simultaneously, and product lumber recovery is low.Application number is a kind of method of producing clad steel plate disclosed in the Chinese patent of 201110179993.X, there is the problem that production process processing capacity is large, lumber recovery is low equally.
Summary of the invention
The purpose of this utility model is intended to the defect overcoming prior art, there is provided a kind of and change the section configuration of slab by regulating narrow copper plate and wide copper coin angulation, thus minimizing composite plate blanks adds the milling amount in man-hour, avoid producing twin drum, improve the combined type continuous cast mold of lumber recovery.
For this reason, the solution that the utility model is taked is:
A kind of combined type continuous cast mold, comprise narrow copper plate and wide copper coin, it is characterized in that, the cavity section configuration formed by two pieces of wide copper coin inwalls and two pieces of narrow copper plate inwalls is isosceles trapezoid or hexagon, described hexagon system is made up of two isosceles trapezoids, and going to the bottom of upper isosceles trapezoid is equal with the upper base width of lower isosceles trapezoid.
Described section configuration is the base angle 1 of isosceles trapezoid is 60 ° ~ 85 °.
Described section configuration is that two sides of hexagonal upper isosceles trapezoid angle that slopes inwardly is greater than two side angles of inclination of lower isosceles trapezoid, hexagon apex angle ss 2 is 95 ° ~ 120 °, base angle 2 is 65 ° ~ 90 °, and β 2+ α 2 >=180 °, the height a of lower isosceles trapezoid is 1/4 ~ 2/3 of thickness of strand H.
Described hexagonal lower isosceles trapezoid comprises rectangle.
The beneficial effects of the utility model are:
The utility model structure is simple, small investment, is easy to realize and safeguard, can go out be suitable for the continuous casting billet that composite steel billet produces by continuous casting; And crystallizer does not affect prior art to continuous casting billet surface and the quality control level in heart portion, and the on-line width adjustment technology of fourplatemold.The continuous casting billet produced, for processing composite steel billet, can simplify composite steel billet process, significantly reduces composite steel billet milling amount, improves steel plate edge shape, reduces trimming loss, improves working (machining) efficiency and lumber recovery.

Detailed description of the invention
The utility model combined type continuous cast mold system is made up of left narrow copper plate 1, upper wide copper coin 2, right narrow copper plate 3, lower wide copper coin 4.The crystallizer cavity section configuration formed with left narrow copper plate 1, right narrow copper plate 3 inwall by upper wide copper coin 2, lower wide copper coin 4 is isosceles trapezoid or hexagon.Wherein hexagon system is made up of two isosceles trapezoids, and going to the bottom of upper isosceles trapezoid is equal with the upper base width of lower isosceles trapezoid.Another variants hexagonal is lower isosceles trapezoid is rectangle.
Be described further below in conjunction with the large the utility model of drawings and Examples.
Embodiment 1:
Adopt the fourplatemold of isosceles trapezoid section as shown in Figure 1, production thickness is 250mm, isosceles trapezoid base width 2200mm, β 1=110 °, α 1=70 °, and section is the continuous casting steel billet of isosceles trapezoid.Two pieces of continuous casting billet trapezoidal cross-section bases process as composite surface, the weld seam work area to be added of working width 30mm, and now working depth is about 5.5mm, and processing capacity is reduced to 6% of former processing capacity, improve working (machining) efficiency 18%.
