Quenching furnace device capable of realizing continuous quenching of multiple samples

Abstract

The invention relates to a quenching furnace device capable of realizing continuous quenching of multiple samples. The quenching furnace device comprises an upper cover, a furnace tube, a lower cover, a base and a plurality of hooks, the upper cover and the lower cover are detachably and hermetically connected with the furnace tube respectively; the upper cover comprises an upper cover shell and a rotating body, the rotating body comprises a rotatable part and a fixed part, a circle of groove is formed in the upper surface of the fixed part, and a falling notch is formed in the groove; a circle of convex edge is arranged at the bottom of the rotatable part, and a plurality of limiting notches penetrating through the upper surface of the rotatable part are formed in the convex edge; the upper surface of the rotatable part is fixedly connected with a force transmission column, the multiple hooks are hung on the edge of the groove, the hooks are located in the limiting notches in a one-to-one correspondence mode, and the quenching medium container is right opposite to the lower portion of the furnace tube. Through the arrangement of the rotating body, a plurality of groups of samples can be hung at the same time, and each group of samples fall off from the falling notch, so that continuous quenching is realized, and the efficiency of the whole quenching process is greatly improved.

Description

technical field [0001] The invention relates to the technical field of quenching furnaces, in particular to a quenching furnace capable of continuous quenching and comparative quenching with various quenching media. Background technique [0002] Quenching refers to a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. Commonly used quenching media are brine, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces. For steel, the quenching process generally heats the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keeps it warm for a period of time to make it fully or partially austenitized, and then austenitizes it at a temperature greater than the critical temperature. The cooling rate is a heat treatment process in which th...

AI Technical Summary

Problems solved by technology

If multiple samples are heated and quenched after reaching the holding time respectively, the furnace cover needs to be opened each time for testing, which may cause temperature fluctuations and inconvenient operation

If only one sample is heated at a time, the heating time will be greatly prolonged, which will affect the efficiency of quenching processing
