Product description

Product Name: Black Transparent Electromagnetic Oven panel

Guangdong Kedi Glass-ceramic Industrial Co., Ltd.

1 Scope of Application

This manual applies to black transparent glass ceramics panel.

2 Reference Standard

Guangdong Province Industry Standard, Q/PKT 02-2007

Broad Black Transparent Glass-ceramic Plate.

3 Material

Black transparent glass ceramics are used to meet the special requirements of electromagnetic oven

Standard features which are to be described respectively, fit the RoHS rules.

3.1 Characteristics of glass ceramics

3.1.1 Maximum Service Temperature:

The original color of the plate will change at the temperature of 780 ℃.

3.1.2 Temperature of Thermal Shock

780 ℃ (thermal shock resistance test: after heating the electric furnace and keeping the temperature at 780℃, place the plate in it for 30 minutes, the characteristics of the plate keeps stable when it is immediately thrown into the water).

4 Specifications

4.1 The size and shape of the electromagnetic stove panel are subject to the requirement diagram.

4.2 Dimensions and test method of the product are measured in accordance with the design and the Vernier caliper.

4.3 The amount of deformation is within 1.0mm (in the process of testing, the product should be placed on the horizontal platform, and measured by a plug gauge coordinated a standard ruler. Only ruler is allowed to be place on the plate.)

4.4 The allowance error of thickness is within ±0.5mm.

4.5 The allowance error of the straight edge is within ±0.5mm. The arc edge is smooth, without broken and flanging edge.

4.6 The R angle of product is within ±0.3mm. The perpendicularity and parallelism is presented in Figure 1.

a or a’ should be within 1mm:

b or b’ should be within 1mm:

Edge c should be alongside with the right angle.
