Figure 5 - steel strip rolling deformation resistance
29 gleeble tester for the high temperature of SUS430 steel stress - really
True strain curve.
In figure 5 -
28 curve is, deformation rate, high temperature deformation resistance of steel increases.
The steel temperature at 1100 ℃, the deformation resistance in 75 -
100 mpa, 950 ℃ when the deformation resistance up to 150 mpa.
Compared with the high temperature deformation resistance at low speed by 100 mpa.
At the same temperature condition, the deformation resistance is far lower than the steel SUS304.
For SUS430 steel, there is no mill capacity problems in rolling mill load.
According to equipment capacity and SUS8430 steel lower deformation resistance, reasonable distribution of deformation load, improve quality, improve production efficiency.
Figure 5 -
30 for 30 mmsus430 hot strip roughing mill typical under time pressure and finishing mill load distribution ratio.
In roughing head a few times, should guarantee the slab rolling bite, play a few times after rolling mill capacity, increase rate under time pressure.
In order to guarantee the stability of the rolling in the finishing mill export frame play guarantee has the certain deformation, make effective control of strip flatness and thickness.
