Abstract

The invention belongs to the technical field of metallurgic assisting equipment, and specifically discloses a hard alloy coating furnace. The hard alloy coating furnace comprises a furnace body, a first cooling box and a second cooling box, wherein smoke under the temperature of 25-200 DEG C are stored in the first cooling box and the second cooling box; an air suction pipe communicates with the first cooling box; one end, far away from the first cooling box, of the air suction pipe penetrates the second cooling box and communicates with the inner part of the furnace body; a first air outlet pipe communicates with the first cooling box; one end, far away from the first cooling box, of the first air outlet pipe communicates with the second cooling box; an air pump is arranged on the first air outlet pipe; a second air outlet pipe is arranged on the second cooling box; and one end, far away from the second cooing box, of the second air outlet pipe communicates with the furnace body. Thehard alloy coating furnace aims at solving the problem of product deformation caused by fast cooling of a coating furnace in the prior art.

Description

technical field [0001] The invention belongs to the technical field of metallurgical auxiliary equipment, and specifically discloses a cemented carbide coating furnace. Background technique [0002] In the production of cemented carbide deep processing industry, because cemented carbide coating products have the characteristics of high surface hardness, good wear resistance, small friction coefficient and low thermal conductivity, all high-end cemented carbide products need to be coated. Coating is a material surface strengthening technology. In a high temperature environment of thousands of degrees, the mixed gas interacts with the surface of the workpiece to form a metal or compound solid film or coating on the surface of the workpiece. After the coating process is completed, it is necessary to wait for the coating furnace to cool down by itself. During the process of opening the heating reaction furnace cover, a large amount of smoke will be discharged from the furnace co...
