Problems solved by technology

[0002] The current ceramic sintering process uses coal-fired combustion for preheating and sintering. The combustion chamber in the pusher kiln adopts a coal-fired flame-insulated (baking) structure. The kiln with this structure cannot be fired. High-temperature ceramics can only be fired with some low-temperature ceramics. The surface gloss of ceramic products is often poor, the sintering temperature fluctuates greatly, the color is uneven, the product quality is difficult to control, the consumption of raw coal is large, environmental protection is not up to standard, and the output is low. The development of the ceramic industry

Embodiment Construction

[0011] Referring to the accompanying drawings, it is a ceramic sintering process of coal and gas co-firing, which obtains finished products by preheating, sintering and cooling the green body. It is characterized in that: coal preheating and gas sintering are used in the ceramic sintering The two combustion methods, that is, the coal-fired flame-fired combustion method is used for preheating and the gas-fired direct-flame combustion method is used for sintering. The gas is liquefied gas, natural gas or coal gas; Combustion chamber for naked burning;

[0012] When producing low-temperature ceramic products, the combustion temperature of coal is 1100°C, while the combustion temperature of gas is less than 1300°C;

[0013] When producing high-temperature ceramic products, the combustion temperature of coal is 1250°C, and the combustion temperature of gas is less than or equal to 1500°C.

[0014] A ceramic pusher kiln for co-firing coal and gas, which includes a preheating sectio...

Abstract

The invention relates to a ceramic sintering process and a pusher kiln for coal-fired and gas-fired mixed firing. It is formed by transforming the existing sintering process and pusher kiln; The sintering process of the combustion method is to add a combustion chamber 4 that uses gas as a raw material to burn in the existing pusher kiln. The combustion chamber adopts a direct flame (bare burning) structure in the furnace; (Flame type); sintering uses a gas combustion chamber to directly sinter the green body. The present invention is novel in design. The process and kiln structure are simple, and the sintering process of the present invention and the pusher kiln are used to produce ceramics, which shortens the sintering time, improves product quality and production efficiency, and has a good glaze finish, which reduces the sintering cost, that is, the product quality can be improved by ten. More than 100 percent, the output is increased by nearly 1 times, the comprehensive cost is reduced by 20%, and the efficiency of the kiln is improved, the smoke emission is reduced, and the environmental pollution is improved. It is an advanced sintering process and pusher kiln for ceramic products.
