The invention discloses a method for optimizing a thermal regulation of a nucleation and crystallization furnace of neoceramic glass. The steps comprise 1) collecting actual parameter of heat treating furnace process, 2) designing and calculating models, 3) calculating the temperature of neoceramic glass panel products in any position of the furnace via setting the actual heat treating furnace processing parameter, thereby confirming the retention time of the neoceramic glass in nucleation segment and in crystallization segment. The best processing condition can be obtained by employing the method of the invention, thereby realizing low cost and low energy-consumption of the neoceramic glass panel finally.
Description
Technical field [0001] The invention relates to a method for optimizing the thermal system of a glass-ceramic nucleation crystallization furnace, and aims to realize low-cost, energy-saving, and consumption-reducing production of glass-ceramic panels. Background technique [0002] Because of its superior structure and performance, glass-ceramics are widely used in household glass-ceramic products such as low-cost kitchen appliances, cooking utensils that can withstand high-temperature shocks, etc., and has become a representative of a new generation of household consumer products. Household glass-ceramic panel products mainly include flat and smooth oven lids and stove top plates, heating plates and internal shells of microwave ovens, stove tops of electromagnetic stove panels or gas stoves, fire doors and stove wall windows, and various cooking utensils. As a key component of electrical appliances, the glass-ceramic panel has its strength, thermal expansion, high temperature res...
