Embodiment Construction

[0019] like Figure 1~2 The shown wear-resistant ceramic composite guide plate for the chute area of ​​CDQ coke oven includes a cuboid plate body 1, an inclined surface 2 is provided at one end of the plate body, and oval through holes are provided in pairs on the plate body 1 3. The number of through holes 3 is preferably 6, which are arranged in two rows up and down. The inclined surface 2 forms an obtuse angle with the right-angled side adjacent to the plate body 1, preferably an obtuse angle of 135°. The distance between the through holes 3 and the ends of the inclined surface 2 Smaller than the distance between the through hole 3 and the other end of the plate body 1; a layer of heat insulating material 4 is bonded to the bottom of the plate body 1.

[0020] Wherein, the slope 2 can also be designed as an arc.

Abstract

The invention discloses a wear-resistant ceramic complex phase deflector for a chute area of a dry quenching furnace. The wear-resistant ceramic complex phase deflector comprises a cuboid plate body, wherein an oblique plane is arranged at one end of the plate body, and pairs of elliptical through holes are formed in the plate body. The wear-resistant ceramic complex phase deflector disclosed by the invention is prepared from a nitrogen-oxygen complex phase material through high-temperature firing, is stable in size, high in high-temperature strength, washout-resistant, and small in wearing coefficient.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a wear-resistant ceramic composite-phase deflector for the chute area of ​​a CDQ coke oven. Background technique [0002] With the increasing size of CDQ coke ovens, users have higher and higher requirements on the life of coke ovens. The deflector device plays the role of adjusting the air volume and direction of the hot air flow. It is installed in the chute area of ​​the CDQ oven to prevent red coke from drifting and stabilize the process parameters in the furnace. [0003] The traditional guide plate of CDQ coke oven adopts alloy plate imported from abroad, which is expensive and has a short service life in the high-speed airflow mixed with coke powder, which has a great impact on the long-term continuous use of CDQ coke oven. Contents of the invention [0004] Purpose of the invention: The purpose of the present invention is to provide a wear-resistant ...
