Embodiment 1

[0031] The invention provides a dry quenching coke tank, which comprises a coke tank body, the coke tank body includes a tank body, a refractory fiber felt 3 and a grid; the tank body is formed by masonry and splicing of lining boards; the surface of the refractory fiber felt 3 is evenly laid On the outer surface of the tank body; the grid is stretched and covered on the outer surface of the refractory fiber felt 3 . like figure 1 As shown, the steel structure and anchors are too small in size and are not marked in the figure.

[0032] Further, the tank body includes a cylindrical section tank body and a cone section tank body connected to the bottom of the cylindrical section tank body, and the liner prefabricated block also includes a cylindrical section liner prefabricated block 1 and a cone section liner prefabricated block 2. The tank body of the cylindrical section is formed by masonry and splicing of the prefabricated block 1 of the lining plate of the cylindrical sect...

Embodiment 2

[0039] The invention provides a method for producing a CDQ coke tank, which is used to manufacture the CDQ coke tank provided by the invention, comprising the following steps:

[0040] The liner prefabricated block is formed, and the high-strength refractory castable is molded and then fired at a high temperature to obtain the liner prefabricated block; the tank body is formed, and the liner prefabricated block is spliced ​​to obtain the tank body; the refractory fiber felt 3 is laid, Wrap a layer of refractory fiber felt 3 on the outer surface of the tank body; lay a grid, lay a layer of grid on the outer surface of the refractory fiber felt 3, stretch and fix the grid so that the grid is wrapped in a stretched state The outer surface of the refractory fiber felt 3 is used to obtain the main body of the coke tank; the installation is fixed, and the main body of the coke tank is installed in the matching structural steel to obtain the coke tank for CDQ.

Abstract

The invention discloses a dry quenching coke tank and a production method thereof. The dry quenching coke tank comprises a coke tank body, the coke tank body comprises a tank body, a refractory fiberfelt and grids; the tank body is formed by laying and splicing lining plate precast blocks; the refractory fiber felt is arranged on the outer surface of the tank body; and the grids are coated on theouter surface of the refractory fiber felt in a stretching state. The grids are tensioned, and prestress is applied to the coke tank, so that the stress is uniformly transferred to a refractory working layer, the tensile stress generated by coke on the side wall of the coke tank is counteracted, the defect that the lining is easy to crack and peel off is avoided, and the service life of the coketank can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment manufacturing, in particular to a CDQ coke pot and a production method. Background technique [0002] The CDQ coke tank is the equipment used to hold red coke in conjunction with the CDQ oven. The tank body is divided into three parts. It is the door opening mechanism of the coke tank. When in use, the red coke produced by the CDQ coke oven is discharged into the CDQ coke tank and transported to the CDQ coke oven by rail. When the CDQ coke tank is transported and lifted by the train, the coke tank door opening mechanism is closed , when the CDQ coke tank is lifted to the top of the CDQ furnace and placed on the special mechanism, the door opening mechanism is opened, and the red coke is discharged into the CDQ furnace. The above process is continuously circulated during the CDQ process. [0003] The structure of the traditional coke tank is mostly I-shaped steel frame and alloy l...
