Abstract
The invention discloses a sintering reduction furnace which comprises a combustion chamber and a furnace frame arranged outside the combustion chamber. The combustion chamber is provided with five heating areas. Each heating area is provided with an independent thermocouple. Heating elements are arranged inside the combustion chamber and distributed on the upper portion and the lower portion of the combustion chamber. An inner container of the combustion chamber is made of austenite chromium-nickel stainless steel. The combustion chamber is divided into the five independent heating areas, and concurrent heating on the upper portion and the lower portion inside the combustion chamber is adopted, so that comprehensive heating of products can be realized while temperature of each heating area is controlled independently, performance of the sintering reduction furnace is optimized, and product quality is guaranteed.
Description
Technical field
The present invention relates to a kind of industrial furnace, be specifically related to a kind of sintering and reducing stove.
Background technology
The sintering and reducing stove is that a part in the sintering line is produced in serialization, and existing sintering and reducing furnace temperature control is accurate not, and adopts the mode of single-side heating more, causes heating even not, impact that all can be certain on the mass formation of product.
