Description
Technical field
The present invention relates to twin roll strip casting technology fields, are specifically a kind of casting method of twin roll strip.
Background technology
In general, the step of manufacture made-up belt, is as follows：Pass through casting process (continuous casting process)
Slab (slab) is manufactured with molten steel, which forms hot rolled coil (hot- by reheating with hot rolling (hot-rolling) process
rolled coil).The hot rolled coil is subjected to the torrid zone in thermal annealing (hot annealing) ＆ pickling (pickling) production line and moves back
Fiery (hot band annealing) and pickling, then the hot rolled coil final products are shaped to by cold-rolled process.Above-mentioned continuous casting
Method is very complicated because casting process and roll milling process are to be performed separately.Further, since to allow after moulding
Slab must just be reheated by performing roll milling process, therefore consume big energy, and continuous cast method is not in terms of economy and environment
Favored.The shortcomings that in order to overcome continuous cast method, has developed the double roller band that sheet metal (made-up belt) is directly manufactured using double roller
Base casting method.
In existing twin roll strip casting process, the fringe region of the made-up belt opposite mistake compared with other regions of the made-up belt
Heat, then due to fringe region set retardation phenomenon, the thickness of the made-up belt may edge region locally increase (about 50mm) or
The made-up belt may be torn.This phenomenon is referred to as " edge protuberance ".Fringe region set retardation phenomenon can be considered as twin roll strip
The characteristics of casting process.During roll milling process, since the fringe region may relatively thick or hot, the reduction ratio of the width of made-up belt
It may variation.Therefore, the shape of made-up belt may be deformed or is likely to form due to bad rolling situation caused by edge waviness
Crackle, so as to reduce yield rate；In addition, in casting process, if the heat transfer control between melt and crystallization roll is unstable
It is fixed, easily make twin roll strip Tissue distribution uneven.

1.15~3.35%, copper 0.15~0.35%, tin 0~0.12%, phosphorus are less than 0.01%, remaining is iron；
2) by raw material by vacuum medium frequency induction furnace melting, after raw material all fusing, melt temperature is risen to 1260~
1320 DEG C, the slag on surface is removed, melt temperature is finally risen to 1330~1460 DEG C, melt is refined；
3) melt refined is supplied to the crystallization roll reversely rotated by two and the sealing plate of both sides by injection nozzle
In the molten bath of formation, the flat nozzle of a row is respectively arranged with above the outside of two crystallization rolls, by flat nozzle to crystallization roll table
Face spray cooling liquid, the melt in molten bath form the made-up belt runic of predetermined thickness as the rotation of crystallization roll solidifies and is exported；
4) pretreatment is polished to made-up belt runic using the abrasive brush of 100~300 mesh, then using 2000~3000 mesh
Nonwoven fabric brush roll made-up belt runic is processed by shot blasting, the roughness of made-up belt is reached 0.05~0.15 μm；
5) made-up belt after essence is thrown carries out no-core winder, is packaged, and is twin roll strip product.
As further embodiment of the present invention：The degree of superheat of molten bath upper surface is controlled at 80~100 DEG C in the step 3).
