The structure of the roller body with spiral liner for oil inlet and outlet at both ends is made of stainless steel to prevent the roller body from rusting. The spiral runner can better cover the surface of the roll body, and the production process is also relatively controllable and easy to operate. Both ends of the roller body can feed oil and discharge oil at the same time, which can more efficiently reach the temperature required by production, and also reduce the time of feeding oil and discharging oil. The  pressure inside the roll body is reduced.
