Description

Double trolley structure and production process for tunnel-type continuous high-temperature annealing furnace for oriented silicon steel

Technical Field

The invention relates to the technical field of annealing of oriented silicon steel, and in particular to a double-trolley structure and a production process for a tunnel-type continuous high-temperature annealing furnace for oriented silicon steel.

Background technique

Grain-oriented silicon steel is a special electrical steel material with the characteristics of low magnetic permeability and low magnetic loss. It is widely used in power equipment such as transformers, motors, and generators. However, during the manufacturing process, oriented silicon steel will have problems such as decreased magnetic properties and stress accumulation. In order to solve these problems, oriented silicon steel needs to be annealed. The oriented silicon steel annealing furnace single car plays a key role in the annealing process. It can provide a certain temperature and atmosphere control, and achieve the desired magnetic and mechanical properties by heating and cooling the oriented silicon steel.

The existing single-trolley production of oriented silicon steel annealing furnace has low production output and high energy consumption. Each car can only carry one roll of silicon steel, which wastes production time and thus affects production efficiency. At the same time, the hoisting structure of the trolley is easily heated during production. When the operator uses external hoisting equipment to hoist after production is completed, the high-temperature hoisting structure is easy to cause damage to the production personnel. Therefore, it is necessary to design a double-trolley structure and production process for a tunnel-type oriented silicon steel continuous high-temperature annealing furnace.
