Hardening furnace with fume exhaust device

Abstract

The invention discloses a hardening furnace with a fume exhaust device, which comprises a hearth of the hardening furnace, a fume deposition box, a fume exhaust tube, an adjusting valve and a fume exhaust machine. The hardening furnace with the fume exhaust device is characterized in that the fume deposition box is arranged at the lower part of the hearth of the hardening furnace; and the fume deposition box, the adjusting valve and the fume exhaust machine are sequentially communicated with each other through the fume exhaust tube. The hardening furnace exhausts excessive oil smoke in time and reduces deposited carbon of the hearth of the hardening furnace so as to guarantee hardening performance of the hardening furnace. A work for manually clearing a deposited carbon layer can be reduced by 1-2 times in one year, thereby the maintenance cost of the hardening furnace is reduced, and the production cost of a factory is reduced.

Description

technical field

[0001] The invention relates to a quenching furnace, in particular to a quenching furnace with a lampblack device, which can clean the furnace and reduce carbon deposits in the furnace. It belongs to the field of quenching treatment machinery. Background technique

[0002] Many metal processing parts, such as hardware parts, auto parts, tools, etc., need to be quenched to increase their surface hardness in order to improve their wear resistance and contact strength to meet their respective design needs. In order to achieve the above purpose, a quenching furnace is usually used Achieved. In the prior art, the quenching furnace will produce a lot of oily fumes during the process of quenching the metal parts to be processed. If the excess oily fumes are not discharged from the quenching furnace in time, these excess oily fumes will be deposited on the inner wall or bottom of the furnace in large quantities. Formation of carbon deposits underneath. As the carb...
