Abstract
A kind of high pulling rate equilibrium efficient heat transfer crystallizer copper pipe, belongs to steelmaking technical field.The crystallizer copper pipe is rectangular or rectangle, slots in crystallizer copper pipe huyashi-chuuka (cold chinese-style noodles) and reinforces cooling effect.Crystallizer corner 0~28mm range internal recessing density is more than crystallizer other positions (other positions fluting consistent in density).Crystallizer groove depth h and crystallizer wall thickness B ratios h/B is suitably adjusted according to steel grade and crystallizer change in location.Crystallizer copper pipe inner cavity taper is using continuous taper curve, more taper curves or single taper curve.The circular arc that crystallizer copper corner of tube is right angle or radius is 2~35mm.The utility model is by slotting common square billet or rectangular-blank crystallizer copper pipe huyashi-chuuka (cold chinese-style noodles), enhance the heat convection of strand, and crystallizer different location groove width, depth and density are adjusted, making strand, temperature and stress are uniform everywhere, strand defect caused by temperature and unbalanced stress etc. can be effectively avoided, slab quality is improved while improving pulling rate.
Description
Technical field
The utility model is related to steelmaking technical fields, particularly relate to a kind of steel-making continuous casting uniformly cooling high pulling rate crystallizer
Copper pipe.
Background technology
In casting process, corner Two-Dimensional Heat and edge unidirectionally cool down for common tubular type square billet or rectangular-blank crystallizer copper pipe
Strand peripheral surface temperature difference, strand corner and deviation corner shrinkage is caused to be more than edge so that corner and deviation corner
Position generates certain thickness air gap and is more than edge.The characteristics of deviateing angular zone one dimensional heat transfer, cooling velocity are less than corner and side
Portion, final shell thickness are less than corner and border region.Shell thickness unevenness causes corner and deviation angular zone to easy to produce and answer
Power is concentrated and the mass defects such as crackle or recess occurs, and causes strand to be scrapped in batch or bleed-out accident is caused to occur.
High casting speed continuous casting makes crystallizer thermic load increase, and is more than recrystallization device temperature so as to cause crystallizer copper pipe temperature
Degree, causes copper pipe to deform；Boiling water is cooled down in order to prevent, it is necessary to increase cooling water pressure；Crystallizer cooling water temperature increases, knot
Dirt increases.Therefore, the improved target of crystallizer copper pipe is exactly to improve cooling efficiency, reduce copper pipe surface temperature.Crystallizer copper pipe
The higher material of recrystallization temperature, such as CuCrZr can be selected in material.Reduce copper pipe wall thickness, copper pipe internal surface temperature can be reduced, but
Copper pipe hull-skin temperature is still very high, the problem of thus will produce fouling.In order to reduce copper pipe hull-skin temperature, need to increase
Water either reinforces turbulent flow, to improve cooling efficiency.Therefore, the utility model proposes slot to crystallizer copper pipe huyashi-chuuka (cold chinese-style noodles)
Processing strengthens the turbulence effects of cooling water while reducing the wall thickness of copper tube sections position.
Invention content
The utility model provides a kind of steel-making continuous casting uniformly cooling high pulling rate efficient heat transfer crystallizer, can solve square billet
Or rectangular-blank crystallizer copper pipe the problems such as shell thickness is uneven inside crystallizer in use.
A kind of steel-making continuous casting uniformly cooling high pulling-speed crystallizer copper tabe, it is characterised in that：For rectangular or rectangle copper pipe knot
Structure is slotted in crystallizer copper pipe huyashi-chuuka (cold chinese-style noodles)；Crystallizer corner 0~28mm range internal recessing density and other positions fluting density
It is 3~1 than value range；Groove width a and crystallizer sink distance s, a/s are required according to cooling in 0.1~10 value；Groove depth
H and crystallizer copper thickness of pipe wall B, h/B are required according to turbulence effects in 0~0.7 value.
Wherein, crystallizer copper pipe inner cavity taper is using continuous taper curve, more taper curves or single taper curve.
The circular arc that crystallizer copper corner of tube is right angle or radius is 2~35mm.
Crystallizer copper pipe huyashi-chuuka (cold chinese-style noodles) sink groove fillet radius r is in 0.2~4mm range values.
The above-mentioned technical proposal of the utility model has the beneficial effect that：
In said program, by the way that common square billet or rectangular-blank crystallizer copper pipe huyashi-chuuka (cold chinese-style noodles) are carried out slot treatment, enhance strand
In the heat convection for deviateing angular zone so that deviation corner shell thickness is consistent with corner and edge, eliminates in corner and deviation
The stress concentration of angular zone solves common square billet or rectangular-blank crystallizer copper pipe same section cooling velocity in use
Inconsistence problems, so as to effectively avoid the defect caused by strand temperature and unbalanced stress etc., while improving pulling rate
Improve slab quality.
