The stick type protection atmosphere quenching furnace has the characteristics of high practicality and easy and convenient operation.
Description
technical field [0001] The invention relates to the technical field of quenching furnaces, in particular to a stick-type protective atmosphere quenching furnace. Background technique [0002] Quenching is a process in which the workpiece is heated to the critical temperature of the hypoeutectoid steel state in the furnace, then kept for a period of time, and then rapidly cooled to austenitization. Among them, quenching furnaces are needed, which are divided into gas quenching furnaces and liquid quenching furnaces. [0003] However, existing quenching furnaces have the problems of poor practicability and inconvenient installation of quenching parts. Because the existing cooling gas can only pass into the workpiece from one direction, resulting in uneven cooling; The process is cumbersome, time-consuming and labor-intensive. Therefore, it is necessary to design a stick-type protective atmosphere quenching furnace with strong practicability and easy operation. Contents of ...
