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
The invention belongs to industrial Field of Heat-treatment, be specifically related to the furnace roller in a kind of roller hearth type heating furnace used in part thermoforming process.
Background technology
The heat treated moulding process of thermoforming part is undertaken by the roller hearth type heating furnace with or without protective atmosphere.Traditional roller hearth type heating furnace, when processing metal rough piece, in order to mode high temperature causes blank surface oxidation, can add protective atmosphere usually in stove.If do not added protective atmosphere, then need to add coating on the surface of blank to be formed, in mode, it is oxidized in continuous high temperature heat-processed.
Blank coating conventional at present can be divided into aluminium silicon coating or spelter coating, wherein mostly comprises low melting point phase (fusing point is 500-800 ° of C), partial coating can be caused during heating to melt.The coating of these fusings pollutes furnace roller by the moving process of furnace roller.Furnace roller is generally made up of stupalith (mullite, fusible silicon or other stupaliths), it is thick that pollutent can make the diameter of furnace roller increase, the unstable causing blank to move in process furnace increases, and runs, then need to replace contaminated furnace roller if hinder blank.Meanwhile, coated material also may with furnace roller generation chemical reaction, reaction can cause furnace roller rupture or other damage.Therefore, need to make certain sfgd. to furnace roller.
Summary of the invention
The object of this invention is to provide a kind of being applied in thermoforming roller hearth type heating furnace and the furnace roller by blank coating contamination or damage can be avoided.
For achieving the above object, the technical solution used in the present invention is:
A furnace roller for thermoforming roller hearth type heating furnace, is arranged in the roller hearth type heating furnace for part thermoforming, and it comprises roller body, is arranged on described roller body surface with the roller coating preventing the coating of described part from adhering to and reacting.
Preferably, the anti-adhered particles that described roller coating comprises in the pore on the surface being partially fill in described roller body that formed by body material, part covers the substrate layer on the surface of described roller body and is distributed in described substrate layer.
Preferably, described anti-adhesion uniform particles is distributed in the part thereof layer on the surface covering described roller body.
Preferably, described substrate layer is the solid layer formed by stupalith or class glass material.
Preferably, described anti-adhered particles is the microparticle formed by metal nitride and/or oxide compound.
Preferably, the periphery of described roller body is provided with described roller coating.
Preferably, the thickness of described roller coating is 7-15 μm.
Because technique scheme is used; the present invention compared with prior art has following advantages: the present invention is by arranging furnace roller coating; reduce the adhesive attraction of Parts Surface Coating, also can suppress Parts Surface Coating and furnace roller generation chemical reaction, thus effectively can protect furnace roller.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of furnace roller of the present invention.
In above accompanying drawing: 1, roller body; 2, roller coating.
Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment one: as shown in Figure 1, a kind of furnace roller be arranged at for the thermoforming roller hearth type heating furnace in the roller hearth type heating furnace of part thermoforming, comprises roller body 1, the roller coating 2 be arranged on the surface of roller body 1.Roller coating 2 adheres to and reaction for preventing the coating of piece surface to be formed, usually, roller coating 2 is only arranged on the part that the periphery of roller body 1 can contact with part to be formed, roller body 1 two ends for installing the driving part of roller body 1 then without the need to arranging roller coating 2.The thickness of roller coating 2 is 7-15 μm.
Wherein, roller coating 2 comprises substrate layer and some anti-adhered particles.Substrate layer is formed by body material, and it is partially fill in the pore on the surface of roller body 1, part covers on the surface of roller body 1, and anti-adhered particles is then distributed in the part on the surface covering roller body 1 of substrate layer equably.Concrete, substrate layer is the solid layer formed by stupalith or class glass material, and it for blocking the pore on the roller body 1 of pottery, and retains the anti-adhered particles in coating; And anti-adhered particles is the microparticle formed by metal nitride and/or oxide compound (such as aluminium, titanium, boron etc.), it can reduce the adhesive attraction of Parts Surface Coating to furnace roller, also can suppress the chemical reaction between Parts Surface Coating and furnace roller simultaneously.The roller coating 2 of this furnace roller is more stable with its oxide compound than piece surface aluminium silicon coating, has good thermostability and chemical stability.
Anti-adhered particles is mixed in uncured pottery or class glass material; the corresponding position on roller body 1 is worked into by the mode of spraying and/or smear; in order to reach protected effect, layer 2-3 need be smeared with identical structure, thus form the roller coating 2 that integral thickness is about 10 μm.
The roller coating 2 of this furnace roller has following characteristics: the pore of 1, filling the ceramic material surfaces of roller body 1; 2, to suppress and chemical reaction between part aluminium silicon coating or other coatings; 3, the effect suppressing coating to spread mutually is played; 4, the adhesive power between furnace roller material and pollutent is reduced; 5, high temperature resistant to 1000 ° of C.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to spirit of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
