Manufacturing technology for microcrystal glass lining plate

Abstract

The invention discloses a manufacturing technology for a microcrystal glass lining plate. The manufacturing technology comprises the following steps: preparing slurry, mixing and stirring water, gypsum, bentonite and carbon powder; making a housing, uniformly coating a wax mould with the slurry, and scattering sand to the wax mould; drying, after enabling the slurry on the wax mould to be combinedwith sand, to obtain the dry mould housing; dewaxing, enabling the mould housing to be separated from the wax mould; roasting, enabling an opening of the mould housing to be downward, and placing ina hearth; pouring, pouring a high-temperature frit into the mould housing; annealing, to obtain the pre-formed lining plate; and performing nucleating and crystalizing treatment on the pre-formed lining plate, and forming the microcrystal glass lining plate. The provided manufacturing technology for the microcrystal glass lining plate is capable of manufacturing the microcrystal glass lining platewith stronger wear resistance and corrosion resistance, through using the water, the gypsum, the bentonite and the carbon powder as slurry components for preparing the mould housing, forming a pore channel on the mould housing, thereby discharging a gas, and guaranteeing surface quality of the microcrystal glass lining plate.

Description

technical field [0001] The invention relates to the technical field of lining boards, in particular to a manufacturing process of a glass-ceramic lining board. Background technique [0002] At present, the lining plates used in steel mills, cement plants and even the pharmaceutical industry are mostly ordinary steel plates. After long-term use, the steel plates will be severely worn and corroded, and need to be replaced in an average of 1-3 months, which increases the cost of replacement and increases labor intensity of employees. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process for a glass-ceramic liner to solve the above-mentioned problems in the prior art and improve the wear resistance and corrosion resistance of the liner. [0004] The present invention provides a process for manufacturing a glass-ceramic liner, which includes: [0005] Step S1, preparing a slurry, mixing water, gypsum, bentonite and carbon...
