Magnesium oxide dust removal system for oriented silicon steel thermal drawing annealing unit

Abstract

The invention relates to a magnesium oxide dust removal system for an oriented silicon steel thermal drawing annealing unit. The dust removal system includes a pneumatic valve, a dust remover, a fan, and also includes a dust extraction hood, an air curtain and ash conveying equipment, wherein: the dust extraction hood and the air The curtain is installed at the uncoiler and the inlet shear, and is connected to the dust collector and fan through pneumatic valves and air pipes; the ash conveying equipment is located at the lower part of the dust collector, and is responsible for removing the magnesium oxide dust cleaned by the dust collector. Because of the novel structure, the present invention can overcome the defects of the prior art, and especially has the advantages of high dust collection efficiency, low energy consumption and failure rate.

Description

technical field [0001] The invention relates to the dust removal field of a thermal drawing annealing unit for producing oriented silicon steel (abbreviated as CT unit or AT unit, which is also the final finished product unit of oriented silicon steel), and specifically relates to a magnesium oxide dust removal system for a hot drawing annealing unit for oriented silicon steel. Background technique [0002] The CT (thermal stretch annealing) unit is the last process in the production process of oriented silicon steel. The dust removal system at the entrance section has always been a difficult problem for design units and production units, mainly as follows: [0003] 1. The collection efficiency is low, and the dust is easy to accumulate and cannot be pumped away. [0004] 2. It is difficult to determine the position of the dust extraction point. Due to the movement and interference of the equipment, and the dynamic change of the steel coil diameter, it is difficult to deter...
