Description
Technical field
The invention belongs to steel-making continuous casting apparatus field more particularly to a kind of special-shaped billet continuous casting machine crystallizer copper pipe and its manufactures
Method.
Background technology
There are mainly two types of forms for special-shaped billet continuous casting machine crystallizer, and one is combined types, and one is tubular type, big cross section size is different
Parison conticaster crystallizer generally uses combined type, light section special-shaped billet continuous casting machine crystallizer to have combined type also to have tubular type, tubular type
Crystallizer compares fourplatemold, there is simple in structure, the advantages such as repair is easy, and use cost is low.Crystallizer is conticaster core
The heart, and copper pipe is the core component of crystallizer, directly affects conticaster production stability and continuous casting billet quality, existing Hot Metal in Beam Blank connects
Casting machine crystallizer copper pipe using etc. wall thickness design, crystallizer copper pipe is generally using explosion and two kinds of drawing making moulding process, system
In order to guarantee to demould when making, the angular positions R do not have back draught (i.e. up big and down small, to adapt to green shell contraction), when green shell solidifies
The position heat transfer resistance is big, and green shell heat transfer is uneven in crystallizer, and the angular positions R are compared with other positions, and temperature highest, green shell is thin, steel
Water solidifies in crystallizer generates larger thermal stress in the green shell of formation, easily green shell is induced to generate longitudinal crack.Casting for shaped blank continuous
Machine crystallizer copper pipe Simulation on Temperature Field result can be seen that the angles R on copper pipe cross section and reach with web position temperature difference
97.7℃。
Invention content
Technical problem to be solved by the invention is to provide a kind of angles reduction R and web temperature are poor, reduce molten steel and crystallizing
Solidification forms the thermal stress that green shell is subject in device, improves copper pipe cooling uniformity, inhibits Hot Metal in Beam Blank surface longitudinal crack to generate different
Parison crystallizer copper pipe of continuous casting machine
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of special-shaped billet continuous casting machine crystallizer
Copper pipe has：
Copper pipe body, cross section are I-shaped；
Through-hole, runs through the copper pipe body, and the through-hole cross section is I-shaped；
The middle part of the copper pipe body is web；
The web and the interconnecting piece of the copper pipe body upper and lower part are the angles R；
The wall thickness of other parts of the copper pipe body in addition to the angles R is identical；Wall thickness at the angles R is less than other parts
Wall thickness.
When the wall thickness of copper pipe body other parts is 30mm, the wall thickness at the angles R is 25mm.
A kind of manufacturing method of above-mentioned special-shaped billet continuous casting machine crystallizer copper pipe, is crystallized by numerical simulation calculation Hot Metal in Beam Blank
Under the thickness of the angles device copper pipe difference R at the angles R and the temperature difference of web, while calculating copper pipe intensity and can meet ferrostatic pressure and wanting
It asks, it is final to determine the angles R thickness, four angles R wall thickness of copper pipe of beam blank mould are fabricated to thinner than other positions, form not uniform thickness
Copper pipe of beam blank mould；
The uniform thickness copper pipe of beam blank mould made takes the method that the angles R outer wall is planed, and the angular positions R are thinned
To target thickness,
It is block-shaped to improve water jacket nylon, ensures that copper pipe surrounding water seam is uniform in size.
A technical solution in above-mentioned technical proposal has the following advantages that or advantageous effect, by not influence copper pipe strong
Under the premise of degree, the wall thickness of the most slow position (angles R) of copper pipe heat transfer is thinned, improves the position heat transfer rate, reduces the angles R and web temperature
Degree is poor, and reduction molten steel solidifies in crystallizer forms the thermal stress that green shell is subject to, and improves copper pipe cooling uniformity, inhibits Hot Metal in Beam Blank
Surface longitudinal crack generates.

Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Referring to Fig. 1-2, a kind of special-shaped billet continuous casting machine crystallizer copper pipe has：
Copper pipe body, cross section are I-shaped；
Through-hole, runs through copper pipe body, and through-hole cross section is I-shaped；
The middle part of copper pipe body is web；
Web and the interconnecting piece of copper pipe body upper and lower part are the angles R；
The wall thickness of other parts of the copper pipe body in addition to the angles R is identical；Wall thickness at the angles R is less than the wall thickness of other parts.
Small special-shaped billet continuous casting machine original BB3 section brass pipe wall thickness is 30mm, surrounding uniform wall thickness, by numerical simulation calculation, R
5mm, as 25mm is thinned in angular position thickness, and the angles R are 48 DEG C with web cross-section temperature difference, as shown in figure 3, more former crystallizer copper
Pipe reduces about half, and cooling uniformity substantially improves.
A kind of manufacturing method of above-mentioned special-shaped billet continuous casting machine crystallizer copper pipe, is crystallized by numerical simulation calculation Hot Metal in Beam Blank
Under the thickness of the angles device copper pipe difference R at the angles R and the temperature difference of web, while calculating copper pipe intensity and can meet ferrostatic pressure and wanting
It asks, it is final to determine the angles R thickness, four angles R wall thickness of copper pipe of beam blank mould are fabricated to thinner than other positions, form not uniform thickness
Copper pipe of beam blank mould；
The uniform thickness copper pipe of beam blank mould made takes the method that the angles R outer wall is planed, and the angular positions R are thinned
To target thickness,
It is block-shaped to improve water jacket nylon, ensures that copper pipe surrounding water seam is uniform in size.
After above-mentioned scheme, by the way that the most slow position (R of copper pipe heat transfer under the premise of not influencing copper pipe intensity, is thinned
Angle) wall thickness, improve the position heat transfer rate, reduce that the angles R are poor with web temperature, and reduction molten steel solidifies in crystallizer forms base
The thermal stress that shell is subject to improves copper pipe cooling uniformity, and Hot Metal in Beam Blank surface longitudinal crack is inhibited to generate.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is used, or without changing
Other occasions are directly applied to by the design of the present invention and technical solution, within protection scope of the present invention.
