Abstract

The invention discloses a box-type multi-purpose furnace for metal heat treatment. The box-type multi-purpose furnace comprises an atmosphere control system; a liquid carbon source is premixed with nitrogen according to a certain ratio after being atomized, so that the uniformity of carbon source atmosphere is ensured; the integration of a gas inlet pipe and a fan enables mixed gas flow to be moreevenly distributed in a heating chamber, so that the phenomenon that carbon deposits in the furnace due to the excessively concentrated distribution of the fluid carbon source can be prevented or reduced, and the maintenance cost is lowered; a bearing cooling system is used for fully cooling a bearing, so that not only is the service life of the bearing prolonged, but the temperature rise of a gas inlet pipe passing through the bearing is also reduced to a certain extent, and the carbon deposition in the pipe is reduced; furthermore, once entering the heating chamber, the carbon source rapidly diffuses in the heating chamber under the action of the fan, so that the reaction efficiency and the uniformity are improved, a carburized layer is more evenly distributed, and the quality of the product is ensured.

Description

technical field [0001] The present invention relates to a metal heat treatment equipment, more specifically, the present invention relates to a box-type multipurpose furnace for metal heat treatment. Background technique [0002] When the traditional box-type multi-purpose furnace is used for carbonitriding, the method of dripping carbon source (methanol, etc.) is often used, but because the drip tube needs to pass through the furnace wall, the carbon source is heated during the process of passing through the furnace wall, and it is easy to produce abnormal Complete cracking causes carbon deposits in the drip tube to be blocked, and the carbon and nitrogen atmosphere in the furnace is unevenly mixed, which makes it difficult to ensure product quality. If the amount of carbon source instillation is increased to increase the depth of the carburized layer, carbon deposits in the furnace will also occur. Cause multi-purpose furnace maintenance, maintenance inconvenience. Conte...
