[0024] Such as figure 1 and image 3 As shown, the present invention provides a lower-drive progressive tension-leveling machine with thermal insulation device, which includes a driving roller 12 fixed on a tension-leveling machine base 10 lined with refractory castable. The transmission roller 12 in the middle is connected to a speed reducer 20 with a variable frequency motor speed regulation via a coupling 23, and the speed reducer 20 with a variable frequency motor speed regulation is installed on the electromechanical support 21. The sprocket on the driving roller 12 in the middle drives one driving roller 12 at the front and rear through the chain 17. A driven roller 1 mounted on the lifting guide cover device 2 is also provided above each of the front and rear driving rollers 12 in the middle. The driven roller 1 is moved up and down on the hydraulic cylinder support 11 by the hydraulic cylinder 9 to compress the billet 25, and clamps the billet 25 together with the drivi...
