Electrical kiln used for firing cadmium red glaze porcelain with three-meter height

Abstract

The invention relates to an electrical kiln used for firing a cadmium red glaze porcelain with three-meter height. The electrical kiln comprises a furnace body and a base, wherein the furnace body is internally provided with a hearth, a furnace shell is arranged outside of the furnace body, a first insulating layer is arranged between the furnace shell and the hearth, and the inner side of the first insulating layer is provided with a first temperature-resistant layer; the base comprises a base shell, a second insulating layer and a second temperature-resistant layer, wherein the second insulating layer is arranged between the base shell and the second temperature-resistant layer, and the hearth is internally provided with first heating resistance wires; the base is provided with second heating resistance wires, the first heating resistance wires are arranged on the middle part and the lower part in the hearth, and the first heating resistance wires count 50%-75% of the whole hearth space; and a spacing between every two wires of the first heating resistance wire is 10-25 centimeters, and a spacing between every two wires of the second heating resistance wires is 10-30 centimeters. The electrical kiln provided by the invention has the advantages that the structure is simple and compact, the distributing wire density is relatively large, the configuration is reasonable, the power effective density is reasonable, the heat uniformity is good, the service life is long, and the application rang is wide.

Description

technical field [0001] The invention relates to an electric kiln for firing three-meter-high cadmium red glazed porcelain. Background technique [0002] At present, the high-temperature kiln equipment for firing three-meter-high cadmium red glazed porcelain has an inner space height of more than 3.5 meters, and the temperature difference between the upper and lower sides of the kiln is large, resulting in obvious color differences between the upper and lower parts of the fired product, and There are also differences in the degree of red gloss and vividness of the various parts of the product, the uniformity is poor, and the product quality is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide an electric kiln for firing three-meter-high cadmium red glazed porcelain with high product quality. [0004] The technical solution of the present invention ...
