Problems solved by technology

10 inspections will extend the construction time by at least 5 days. After each inspection, adjustments are made according to the inspection results, which increases the difficulty of construction control. For construction, when the gray joints are generally biased, the elevation will be super high, and the elevation will be super high. After the height is high, it is very difficult to restore its elevation in the actual construction process; and after the elevation is super high, it will affect the expansion joints at the top of the annular air duct. In the future generation process, due to the refractory Expansion causes quality accidents and affects normal production
[0003] Therefore, there are above-mentioned inconveniences and problems in the known control method of the lining of the cylinder furnace kiln.

[0037] Control method of dry quenching coke oven inner lining masonry

[0038] see now figure 1 , figure 1 It is a structural schematic diagram of each section of the CDQ coke oven lining in the embodiment of the present invention. As shown in the figure, the cylindrical kiln of the CDQ oven is divided into an annular air duct section 1, a chute section 2 and a cooling section 3 from top to bottom, and the annular air duct section, the chute section and the cooling section From the furnace shell to the center of the furnace, the refractory structure is divided into 4 cushion layers of ceramic fiber felt and 5 heat insulating layers of heat insulating bricks. The masonry of refractory fiber blanket and heat insulating layer is carried out by conventional control methods.

Abstract

A building control method of a lining of a tubular kiln is characterized in that the inside of the tubular kiln comprises a circular air passage segment, an oblique passage segment and a cooling segment from top to bottom; a refractory structure of the circular air passage segment, the oblique passage segment and the cooling segment includes a fiber blanket cushion layer, a heat-insulating layer and a refractory brick layer from a shell to the center; the refractory fiber blanket cushion layer and the heat-insulating layer are constructed by the conventional control method. The building control method is characterized by including the steps of a, circular air passage segment controlling; b, oblique passage segment controlling; and c, cooling segment controlling. The building control method has the advantages that the steps are reasonable in design, operating is simple, construction is easier and engineering cost is reduced.

Description

technical field [0001] The invention relates to a method for controlling the lining masonry of a kiln, in particular to a method for controlling the lining masonry of a cylinder furnace. Background technique [0002] Elevation control is very critical in the lining masonry of the cylinder kiln. There are many control methods for the inner lining of the cylinder kiln. Generally, after the masonry construction is completed and the height is 1-1.5m, the surveyor will measure it. According to the measurement results, it will be adjusted through the mortar joint in the subsequent masonry process to ensure Ensure the flatness of the upper surface of the masonry. This control method requires a half-day shutdown for each inspection, leaving it to the surveyor for inspection. Taking a CDQ as an example, the furnace is 21.16m high. 10 inspections will extend the construction time by at least 5 days. After each inspection, adjustments are made according to the inspection results, w...
