Problems solved by technology

Therefore, before it is sintered, the strength of the liner itself is low. In the installation of the liner, there is the problem of difficult installation and fixation on the coke tank, just like many currently used coke tank liners.
Its specific performance is that there are too many fixed points of the liner on the coke tank, the cost is high, and the heat insulation effect is poor; the liner has less fixed points and the stability of the liner is poor
[0004] Therefore, there are above-mentioned inconveniences and problems in the fixed installation of the known liner on the coke pot.

Embodiment 1

[0026] see now figure 1 and figure 2 , figure 1 It is a schematic diagram of the fixed structure of the coke tank liner of the embodiment of the present invention, figure 2 for figure 1 Sectional view of A-A in Fig. The method for fixing the coke tank liner of the present invention, the liner is prefabricated by refractory castables and then baked. It is a rectangular block with a length of 539mm, a width of 500mm, and a thickness of 65mm. A φ12mm stainless steel is arranged on each longitudinal side of the interior. As the liner keel 2, a through hole for passing through the bolt 1 is provided between two keels on the longitudinal top of the block, and the distance between the two keels is 160 mm. The material of the stainless steel lining board keel is stainless steel 0Cr25Ni20. The longitudinal bottom of the block is provided with a groove 4, and each lining plate weighs 40-50kg, and its heavy-duty working temperature is 950 to 1050°C. The fixing method of the coke ...

Abstract

The invention relates to a fixing method of coke pot lining plates. The method is characterized by including the steps of a, according to a coke pot lining plate installation drawing, annularly welding a plurality of brick support plates to the inner-side shell of a coke pot in a layered manner, and forming a plurality of bolt holes in the inner-side shell of the coke pot; b, placing the bottom grooves of the lining plates on the surfaces of the corresponding brick support plates; c, arranging aerogel felt between the coke pot lining plates and the coke pot shell to serve as the thermal insulation and buffer material; d, laying the lining plates from the coke pot shell ring by ring from bottom to top to fix the lining plates. The fixing method has the advantages that the method is simple in fixing device structure and convenient in fixing, the coke pot lining plates are few in fixing points, good in stability, good in thermal insulation effect and long in service life, coke heat loss is reduced, and the method is low in cost, simple, practical and capable of lowering coke pot mounting cost.

Description

technical field [0001] The invention relates to a method for installing a coke tank liner on the inner ring wall of a coke tank shell, in particular to a method for fixing the coke tank liner. Background technique [0002] Dry coke quenching is an advanced technology in coking production. It has the functions of saving energy, reducing consumption and protecting the environment. At the same time, it can improve the quality of coke and play a significant role in promoting the increase of blast furnace production capacity. The coke tank car is one of the main complete sets of equipment in the coke oven CDQ device, which transports coke from the coke oven to the CDQ furnace. The coke tank is the coke container on the coke tank car. The function of the coke tank liner is to seal the coke and protect the coke tank structure from being burned. It is the main part of the coke tank car equipment for safe and efficient operation. It must have the centripetal force on the liner when ...
