Description

[0001] Image photographing system for annealing furnace [0002]

The present invention relates to a filming system for an annealing furnace.

In general, the horizontal annealing furnace is about 200m in length and is divided into five sections to produce the final product, and it is a facility to perform a certain process such as internal heating according to the characteristics.

On the other hand, in the inspection of the annealing furnace, the temperature inside the annealing furnace was lowered to about 500 占 폚 for about 4 hours after the production was terminated and the equipment was stopped. Then, .

Then, when the internal temperature reaches 60 ° C, the operator enters the inside of the annealing furnace through the door and performs various equipment replacement and inspection.

This work is usually carried out at the time of repair work (it takes more than a week to repair work once a year) and is carried out for emergency work even when an internal abnormality occurs in the annealing furnace.

However, such an operation also requires that the inside of the annealing furnace be cooled after the annealing furnace is stopped for at least 24 hours. There is a problem in that productivity is reduced due to a long stoppage time since the operator must go inside and perform confirmation and repair work.

In addition, since the operation of the main shaft is carried out once a year, the replacement amount is calculated in the following year, and the replacement accuracy is low. Therefore, there is a problem that the component must be replaced even though the component life is still remaining.

In addition, there is a problem that the unexpected parts are damaged and the quality of the repair work and the production product is deteriorated due to the urgent purchase or temporary action.
