Abstract
The invention discloses a mixed and alternate rolling technique of a continuous casting and rolling production line of a sheet bar, which is characterized in that: rolling mill data are controlled to lead a rolling mill to adapt to blanks with different steel grades, different thickness and different widths from a duplex line, thus greatly solving the problem of contradiction between production and sales and improving the economic benefit of enterprises.
Description
Affiliated technical field
The present invention is applicable to thin plate rolling technology, is particularly useful for mixed and alternate rolling technique of continuous casting and rolling production line of sheet bar.
Background technology
In SPHC manufacturing enterprise, by a kind of by one group of milling train and two two-wire continuous casting and rolling unit equipment that supply line is formed, during work, roll and other index be regulated, be changed to milling train need according to the blank of the different steel grades on two lines, different-thickness, different wide cuts, produced a series of problems such as influencing operating efficiency.
Summary of the invention
The present invention designs and a kind ofly can solve the rolling technology of mixed and alternate that sheet billet continuous casting and rolling production line is adapted to different steel grades, different-thickness, different wide cuts.
The present invention improves as follows to production technology:
(1) slab to every line heating furnace (A, B two lines) output uses different milling train leveling values to be rolled, and can write down operative employee's manual modification value automatically, automatically the result is applied to next root of this heating furnace.
The improvement of (2) self study aspect
After second heating furnace installed, because the plate of every heating furnace heating has different characteristics, add slab possibility width, steel grade, the thickness difference of two line heating furnaces heating, it is rolling that these characteristics will influence milling train ground.Therefore the self study of mill model is calculated and improve, in self study, consider the factor of two heating furnaces.
The present invention can realize the two-wire continuous casting and rolling production of different steel grades, different-thickness, different in width, has greatly solved the contradictory problems of producing and selling, and has improved the economic benefit of enterprise.
Economic benefit of enterprises
The present invention is further described below in conjunction with example
The specific embodiment
Under the condition of two line heating furnaces operation, the temperature trend of heating furnace A and heating furnace B is different.So, root separately carries out concerning heating furnace A and heating furnace B to the self study of root, so and for down, root separately carries out concerning heating furnace A and heating furnace B to the self study of root, and to consider last and last last for the self study item of slab that next root will be rolling.Logic is as follows:
| Preceding 2 | Last | Current (will be rolling) | The self study item that uses |
| Heating furnace A | Heating furnace A | Z B_A_ | |
| Heating furnace B | Heating furnace B | Z B_B_ | |
| Heating furnace A | Heating furnace A | Heating furnace A | Z B_A_ |
| Heating furnace B | Heating furnace B | Heating furnace B | Z B_B_ |
| Heating furnace A | Heating furnace A | Heating furnace A | αZ B_B+(1-a)Z B_A |
| Heating furnace B | Heating furnace B | Heating furnace B | αZ B_A+(1-a)Z B_B |
Z
B_A: the self study item of the BTB of heating furnace A (root is to root)
Z
B_B: the self study item of the BTB of heating furnace B (root is to root)
α: gain (0-1.0 adjusts according to actual conditions)
Claims (1)
1, a kind of mixed and alternate rolling technique of continuous casting and rolling production line of sheet bar is characterized in that: control milling train data make milling train be adapted to blank from the different steel grades on the two-wire, different-thickness, different wide cuts.
