Firing Furnace {BURNING APPARATUS}

The present invention relates to a kiln, and more particularly, to a kiln in which the atmosphere gas supplied into the furnace has an appropriate flow rate and is in sufficient contact with the baked product to activate an effective reaction.

In general, ceramic electronic components and other plastic products using ceramics such as ceramic capacitors, capacitors, varistors, ferrites, piezo-electric bodies, and the like are molded into a predetermined shape. It is manufactured by manufacturing a molded object and baking the said molded object.

The effective removal of binders used during molding during firing of fired products has emerged as an important process variable to control the quality characteristics, and the removal of these binders is carried out in an independent debinder process called calcining or in a plastic elevated temperature profile. This heat treatment process takes place in a kiln.
