Microwave penetrating corundum refractory brick for microwave oven

Abstract

The invention discloses a microwave penetration corundum refractory brick for a microwave oven. The refractory brick comprises a hollow brick body and a buckling plate; the hollow brick body is formed by mixing and sintering corundum, mullite and glass, the proportion of the corundum to the mullite to the glass is 2: 2: 1, and limiting separation blades are arranged on the front sides of the left inner wall and the right inner wall of the hollow brick body; and the buckling plate is a quartz buckling plate, the buckling plate is bonded with the two limiting separation blades at the same time through high-temperature-resistant glue, the buckling plate is matched with the inner edge of the hollow brick body, and the front side face of the buckling plate is flush with the front side face of the hollow brick body. The microwave penetration corundum refractory brick further comprises a heat insulation unit. The microwave penetrating corundum refractory brick for the microwave oven has relatively high microwave penetrability, ensures that microwaves can quickly penetrate through the refractory brick to heat a material to be heated during microwave heating, also has good fire resistance and heat insulation performance, prevents high temperature in the microwave oven from being radiated to the outside to avoid injury to personnel, and is relatively good in overall structural stability, and personnel can conveniently stack and stack.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a microwave penetrating corundum refractory brick for microwave ovens. Background technique [0002] Microwave heating is the process of using the energy characteristics of microwaves to heat objects. Microwaves are a form of energy (not heat), but can be converted to heat in a medium. The principle is to use microwaves to make the dipole molecules inside the heated body reciprocate at high frequency to generate "internal friction heat" to increase the temperature of the heated material. Without any heat conduction process, the inside and outside of the material can be heated and heated at the same time. , fast and even heating. [0003] When performing microwave heating work, it is often necessary to use a closed environment made of refractory bricks to ensure the normal operation of microwave heating. Refractory bricks refer to refractory materials made of refrac...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing microwave ovens use microwaves to penetrate corundum refractory bricks, but most of them do not have good microwave penetration, resulting in the inability of microwaves to pass through the refractory bricks quickly, which in turn affects the efficiency and quality of microwave heating work, and the refractory and heat insulation performance is relatively general. The actual use effect is poor. Therefore, we propose a microwave penetrating corundum refractory brick for microwave ovens.
