Problems solved by technology

[0003] However, due to the intrinsic properties of most ceramic materials such as chemical bonds, they lack the ability to plastically deform at room temperature, and cannot be processed like metals. Therefore, high-temperature furnaces and other equipment must be used to rapidly heat up and roll ceramics. As a result, the processing of ceramic materials is limited

Embodiment 1

[0033] The vertically placed ceramics are rolled by the front and rear two pressing rolls in the ceramic rolling device. The material of the pressure roller is silicon nitride ceramics, and the dimensional accuracy is ±0.02mm. The double roller spacing of the roller press is adjustable from 0-5mm, and the accuracy is ±0.1mm. The length of the pressing roller is 100mm. The rotational speed of the roller press is 0-10 rpm. Among them, the ceramic to be rolled is a zirconia ceramic plate, the purpose of which is to roll the zirconia ceramic plate, plastic deformation occurs, the thickness is reduced, and the length and width are changed accordingly. Specific methods include:

[0034] 1. Place the zirconia between two carbon cloths, and then between two larger alumina felts, so that the carbon cloth will not directly contact the ceramic roller. The size of the zirconia plate is 10×1×100mm; the carbon cloth is 20mm wide and 150mm long, which can wrap the zirconia plate; the wid...

Abstract

The embodiment of the invention discloses a ceramic rolling device and method, the ceramic rolling device comprises a rolling machine comprising a first compression roller and a second compression roller, and a power supply for electrifying and heating a ceramic laminated part, and a gap between the first compression roller and the second compression roller is used for placing ceramic so as to roll the electrified and heated ceramic laminated part when the rolling machine is started. The conductive heating materials such as the carbon felt and the carbon cloth are heated by electrifying, and the materials arranged inside are heated, so that the aim of quickly heating the ceramic by using very simple devices and steps is fulfilled, and the ceramic can be quickly heated to the temperature at which the ceramic can be plastically deformed within several seconds.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of materials, and in particular, to a ceramic rolling device and method. Background technique [0002] Ceramic materials are often used in daily production. Ceramics have a relatively high melting point, and their plastic deformation needs to be heated to a temperature close to the melting point. For example, hot stamping, hot extrusion and other plastic deformation processing of ceramics in a high-temperature furnace. , [0003] However, because most ceramic materials lack the ability to plastically deform at room temperature due to their intrinsic properties such as chemical bonds, they cannot be processed like metals by rolling. As a result, the processing of ceramic materials is limited. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a ceramic rolling device and method. [0005] A ceramic rolling device, comprising: a rolling machine comprisi...
