Embodiment 1
[0029] refer to Figure 1 to Figure 4 , the present invention includes a support frame body 5;
[0030] The bottom of the support frame body 5 is provided with drive wheels I4 and drive wheels II6 that are horizontally corresponding to each other and connected in the same direction and at the same speed; The speed reducer 9 is connected in transmission; the worm gear reducer 9 is connected in transmission with the transmission motor 8;
[0031] The top of the support frame body 5 is provided with a downward pressure oil cylinder 1, and the telescopic arm of the downward pressure oil cylinder 1 is provided with a fixed seat 2; the fixed seat 2 is provided with a driven wheel 3 that is rotationally connected with the bearing seat; The driven wheel 3, the driving wheel I4 and the driving wheel II6 correspond up and down to each other.
[0032] In order to facilitate the vertical corresponding downward pressure, the driven wheel 3 corresponds to the driving wheel I4 and the driv...
Embodiment 2
[0043] The manufacturing and forming process of H-shaped steel includes the following steps:
[0044] 1) Raw material compatibility: control the weight percentage content of each component in molten iron: C: 0.11; Si: 0.43; Mn: 1.32; P: 0.041; S: 0.005; Cu: 0.37; Cr: 0.36; : 0.09; Nb: 0.04, the balance is iron;
[0045]2) Pouring cast slabs: the tundish baking temperature is 1100°C, the crystallizer is aligned with the arc, and the whole protection casting is used. Among them, the secondary cooling adopts weak cooling, the crystallizer adopts non-sinusoidal vibration, the liquidus temperature is 1517.8°C, and the tundish The degree of superheat is controlled at 20°C, the billet size is 165mm×200mm, and the casting speed is 1.2m / min;
[0046] 3) Rolling cooling: the soaking temperature of the heating furnace is 1230°C, and the billet stays in the furnace for 150 minutes. The final rolling temperature is 910°C outside the flange, and the rolled material is naturally cooled in ...
