摘要： The invention concerns a roll for use in the production of paper, in particular a center roll in a press section of a paper making machine, with which the web is in direct contact and from which the web is detached. In the invention, a composite structure has been formed onto the cylinder mantle of the roll. According to the invention, the roll face is provided with a surface layer which protects the roll from wear and which provides good properties for detaching of the web, this surface layer being formed by thermal spraying of a powder wherein metal and ceramic phases are in the same powder particle. The roll face is additionally provided with a dense layer for protection against corrosion, which layer is made of stainless steel whose chromium content is 10 to 29% and which layer is placed between the surface layer and the roll mantle. The function of the layer for protection from corrosion is to protect the roll mantle from corrosion and to promote the adhesion of the surface coating to the roll. The invention also concerns a method for the manufacture of the roll.
摘要翻译：本发明涉及用于生产纸张的卷，特别是造纸机的压榨部中的中心卷，纸幅与纸张直接接触并且纸幅从其分离。在本发明中，已经在辊的圆筒套上形成了复合结构。根据本发明，辊面设置有保护辊免受磨损的表面层，并且其提供了用于分离幅材的良好性能，该表面层通过热喷涂粉末而形成，其中金属和陶瓷相位在相同的粉末颗粒。辊面另外设置有用于防止腐蚀的致密层，该层由铬含量为10-29％的不锈钢制成，并且该层位于表层和辊套之间。防腐蚀层的功能是保护辊套免受腐蚀，并促进表面涂层与辊的粘附。本发明还涉及一种用于制造卷的方法。

摘要： The invention concerns a roll or cylinder or roll coating for a pulp machine, paper machine, or paper finishing machine, in which application the roll or equivalent comprises a cylinder mantle of cast iron or steel or any other, equivalent metal, which bears the mechanical loads. On the rollor cylinder mantle, fixed to the outer face of the frame mantle, there is a resilient polymer coating, and onto said polymer coating a coating is fixed which is by several orders thinner than the radial thickness of the polymer coating. Said coating fixed onto the outer face of the polymer coating is a metal, ceramic, or cermet coating or a plastic coating. The invention further concerns a method for the manufacture of a roll coating in accordance with the invention as well as the use of such rolls and coatings.

摘要： The surface properties of a roll and/or rolls in a paper machine are affected by regulating the temperature of the roll face by means of an external heating device. In the arrangement, a combination of a heating device and a roll coating is used in such manner that the heating radiation penetrates through the paper or only directly to the roll face, but does not heat the roll itself at a depth greater than the roll face. The roll coating is preferably made of a dark, readily heatable and insulating material. The arrangement of the invention is utilized for example in a calendar and for detaching the paper from a roll.
摘要翻译：造纸机中辊和/或辊的表面特性受到通过外部加热装置调节辊面温度的影响。在这种布置中，加热装置和辊涂层的组合以这样的方式被使用，使得加热辐射穿过纸张或仅直接穿过辊面，但不会在大于辊面的深度加热辊本身。辊涂优选由黑色，易于加热和绝缘的材料制成。本发明的布置例如用于日历中并且用于将纸从辊子上分离。
