Problems solved by technology

Furnace rollers are generally made of ceramic materials (mullite, fusible silicon or other ceramic materials), and pollutants will increase the diameter of the furnace rollers, resulting in increased instability of the motion of the blank in the heating furnace. If blanks are running, the contaminated rollers need to be replaced
At the same time, the coating material may also react chemically with the furnace roll, and the reaction will cause the furnace roll to break or other damage

Embodiment 1

[0017] Embodiment one: as attached figure 1 As shown, a furnace roll installed in a roller hearth heating furnace for thermal forming of parts includes a roller body 1 and a roller coating 2 disposed on the surface of the roller body 1 . Roller coating 2 is used to prevent the coating adhesion and reaction of the part surface to be formed, and usually, roller coating 2 is only arranged on the part that can contact with the part to be formed on the circumferential surface of roller body 1 and gets final product. The driving parts for installing the roller body 1 at both ends of the roller body 1 do not need to be provided with the roller coating 2 . The thickness of the roller coating 2 is 7-15 μm.

[0018] Among them, the roller coating 2 includes a substrate layer and several anti-adhesion particles. The substrate layer is formed by a matrix material, which partially fills in the pores on the surface of the roller body 1 and partially covers the surface of the roller body 1...

Abstract

The invention relates to a furnace roller of a hot forming roller bottom type heating furnace. The furnace roller is arranged in the hot forming roller bottom type heating furnace for a component. The furnace roller comprises a roller body and a roller coating layer which is arranged on the surface of the roller body and is used for preventing a coating layer of the component from adhering and reacting. The roller coating layer comprises a base material layer and anti-adhering particles, wherein the base material layer is made of base materials, pores in the surface of the roller body are filled with a part of the base material layer, a part of the base material layer covers the surface of the roller body, and the anti-adhering particles are distributed in the base material layer. By arranging the roller coating layer, the adhering function on the surface of the component is lowered, the chemical reaction between the coating layer on the surface of the component and the furnace roller can be inhibited, and therefore the furnace roller can be effectively protected.

Description

technical field [0001] The invention belongs to the field of industrial heat treatment, and in particular relates to a furnace roller in a roller hearth heating furnace used in the thermoforming process of parts. Background technique [0002] Heat treatment of thermoformed parts The forming process takes place in roller hearth furnaces with or without protective atmosphere. When the traditional roller hearth heating furnace processes metal blanks, a protective atmosphere is usually added in the furnace in order to cause the surface oxidation of the blanks at high temperature. If there is no protective atmosphere, it is necessary to add a coating to the surface of the blank to be formed to prevent it from being oxidized during continuous high-temperature heating. [0003] At present, the commonly used blank coatings can be divided into aluminum silicon coatings or zinc coatings, most of which contain low melting point phases (melting point is 500-800 ° C), which will cause p...
