Novel firewood-coal-electricity integrated high-temperature equipment for ceramic firing

Abstract

The invention provides a novel firewood-coal-electricity integrated high-temperature equipment for ceramic firing. The novel firewood-coal-electricity integrated high-temperature equipment for ceramic firing comprises an electric-control high-temperature furnace and a firewood-coal combustion furnace. The electric-control high-temperature furnace communicated with the firewood-coal combustion furnace through a smoke channel. The electric-control high-temperature furnace is located above the firewood-coal combustion furnace and used for providing the temperature required for ceramic firing. The firewood-coal combustion furnace is used for providing reductive gas required for ceramic firing. An ash pond is arranged below the firewood-coal combustion furnace. The novel firewood-coal-electricity integrated high-temperature equipment for ceramic firing has the beneficial effects that when the firewood-coal-electricity integrated high-temperature equipment is used for ceramic firing, a green body to be fired is placed in a hearth of the electric-control high-temperature furnace, a temperature source is provided by the electric-control high-temperature furnace, an atmosphere source (the reductive gas) is provided by the firewood-coal combustion furnace, the atmosphere source provided by the firewood-coal combustion furnace enters the hearth of the electric-control high-temperature furnace through the smoke channel and air holes, and the ceramic firing quality is greatly improved.

Description

Technical field [0001] The invention belongs to the field of electrical equipment, and particularly relates to a novel diesel-coal-electric integrated high-temperature equipment for firing ceramics. Background technique [0002] Ordinary electric furnaces are sintered in air and only provide an oxidizing atmosphere, which can be used to fire ceramic materials that do not require a reducing atmosphere. However, the official porcelain of the Song Dynasty (including Ru porcelain, Jun porcelain, Longquan celadon, Ge Kiln porcelain and Di Kiln porcelain) belonged to the celadon system, and the firing process required approximately 600-980 o Oxidation flame of C, about 980-1260 o C (including the cooling process) of the reduction flame two stages, the official porcelain works undergo kiln changes in the reduction atmosphere, due to Fe 2 O 3 It is reduced to FeO and presents beautiful azure, pink, egg or shrimp blue (Ti 4+ , Cu 2+ Ion as a color aid). Temperature and atmosphere are two...
