Problems solved by technology

However, the existing heat-resistant ceramic plates are generally produced by a simple one-time pressing-one-time glazing method, and their expansion coefficient is relatively large and water-absorbing, which cannot meet people's basic needs when used, and because the ceramic plates are relatively rough, resulting in Market acceptance is not high

Abstract

The invention provides a method for preparing a heat-resisting ceramic plate, and relates to the field of ceramics. The method comprises the following steps that plate raw materials are subjected to ball grinding, the water content is adjusted so that plate blank slurry can be obtained, then, spraying granulation is performed, and after stock bin decaying, an automatic brick pressing machine is used for manufacturing bricks to obtain a plate brick body; glaze raw materials are subjected to ball grinding, the water content is adjusted to obtain glaze slurry, and then the glaze slurry coats theplate blank body to obtain a prefabricated blank; the prefabricated blank is burnt in advance, then, smashing and ball grinding are performed, the water content is adjusted to obtain plate slurry, spray granulation is performed, and after decaying, bricks are manufactured to obtain plates; the plates are fired to obtain a prefabricated plate; the glaze slurry coats the prefabricated plate, and programmed heating firing, programmed freezing cooling and polishing are performed to obtain the finished product. According to the method for preparing the heat-resisting ceramic plate, the manufacturedproduct is good in heat resistance, high in strength, low in expansion coefficient and low in cost.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a method for preparing a heat-resistant ceramic plate. Background technique [0002] Glass-ceramic plates and heat-resistant ceramic plates are the mainstream choices for induction cooker panels in the market, of which glass-ceramic plates are the main ones. The advantages of glass-ceramic plates are good heat resistance, small expansion coefficient, and impervious to water; the main advantage of ceramic plates is their low price. [0003] However, the glass-ceramic plate has a high melting point and low strength. It cannot be polished by mechanized and automatic methods in the production process. It can only be processed by semi-mechanized or pure manual processing. Therefore, its price is generally relatively high, resulting in a higher price for induction cookers. [0004] People have been hoping to obtain ceramic plates with similar properties to glass-ceramic plates to replace expen...
