Abstract

The invention provides a file manufacturing process, which belongs to the technical field of file production, and comprises the following steps: heating a carburizing furnace to 850 DEG C, placing a file workpiece in the carburizing furnace, and preserving heat for 1-1.5 hours; meanwhile, injecting kerosene, and injecting 160-240 ml of kerosene per minute; heating the carburizing furnace to 930 DEG C, conducting heat preservation for 2.5-3.5 hours, and injecting 400-480 ml of kerosene per minute; and stopping injecting the kerosene, lowering the temperature of the carburizing furnace to 860 DEG C, and conducting heat preservation for 1-1.5 h. According to the file manufacturing process provided by the invention, kerosene is injected in the high-temperature state twice, the carburizing effect of the file workpiece is good, after carburizing treatment is conducted twice, the temperature is adjusted again, heat preservation is conducted, residual kerosene in the carburizing furnace permeates into the file workpiece at the temperature, and the quality of the file workpiece is further improved.

Description

technical field [0001] The invention belongs to the technical field of file production, and more specifically relates to a file production process. Background technique [0002] The file requires quenching hardness above HRC60, and the traditional file material uses T12\T13. Due to the high carbon content of this material, surface decarburization is very easy to occur during hot forging and annealing, which not only affects the quality of the final product, but also increases the amount of processing to ensure surface decarburization during processing and increases production costs. Contents of the invention [0003] The purpose of the present invention is to provide a file manufacturing process to solve the technical problem of poor file production quality in the prior art. [0004] In order to achieve the above object, the technical solution adopted in the present invention is to provide a file manufacturing process, including: [0005] S1: Heat the carburizing furnace...
