Nodulation removal device for ignition furnace of sintering machine

Abstract

The invention discloses a device for clearing nodulation for sintering machine ignition furnaces. The device comprises an impact plate, a front fixed plate, a rotating shaft, a rear fixed plate, a bolt, a fixed plate and a movable plate; the impact plate is a flat plate type, and one end is integrally connected with the rear fixed plate through a 95 degree angle; the other end of the rear fixed plate is connected with the movable plate through the rotating shaft, and the movable plate can be rotated in a living state by the rotating shaft; the front side of the impact plate is connected with the front fixed plate, the front fixed plate is parallel with the rear fixed plate, and the fixed plate is arranged between the front fixed plate and the rear fixed plate, and the fixed plate is arranged in parallel as two baffles. One side of the fixed plate is fixedly connected with the movable plate, and the other side is detachably connected with the front fixed plate; the same sides of the impact plate and the fixed plate are welded with a ring, and the ring is provided with a plug-in type pin. The invention can effectively remove the nodulation of an ignition furnace of a sintering machine, protect the refractory material, reduce the sintering energy consumption and reduce the decrease of the non-process sinter yield.

Description

technical field [0001] The invention relates to a maintenance device for a sintering ignition furnace in a steel plant, and more particularly relates to a nodulation removal device for an ignition furnace of a sintering machine. Background technique [0002] The current mainstream sintering machine ignition furnace 1 adopts short flame, low furnace chamber to improve thermal efficiency, and high-layer thick mode of self-heating material layer. The space between the sintering material surface and the top of the ignition furnace becomes smaller, and the high-temperature ignition process A small amount of surface material is more likely to splash and adhere to the surface of the high-temperature refractory material 2 of the ignition furnace, especially on the baffle walls on both sides of the ignition furnace 1 where the temperature is relatively low. tumor mass. [0003] Such as figure 1 As shown, the growth of nodules in the ignition furnace 1 is generally more likely to oc...
