[0002] The pinch roller device is an important equipment on the steel rolling production line, used in the Sancha area of ​​the strip steel. In actual use, the free roller and the active roller of the pinch roller device form a roller gap of a certain size according to the thickness of the strip steel produced. The active roller rotates to pinch and transport the strip steel to the flat conveyor chain. The cooling water volume of the pinch roller device is very large, so after long-term use, the seal of the equipment will be worn, which will cause water to enter the gear box under the active roller.
