Description
Technical Field
The utility model relates to a heat treatment field specifically is a fast cold high temperature tempering furnace.
Background
The high-temperature tempering furnace is used for metal heat treatment in which a quenched workpiece is reheated to a proper temperature lower than the lower critical temperature, and is cooled in air or water, oil and other media after heat preservation for a period of time; or heating the quenched alloy workpiece to a proper temperature, preserving heat for a plurality of times, and then slowly or rapidly cooling; generally, it is used to reduce or eliminate internal stress in quenched steel parts, or to reduce their hardness and strength, in order to improve their ductility or toughness.
After the tempering process of the conventional high-temperature tempering furnace is finished, a natural cooling mode is usually adopted, for example, when the temperature in a hearth is 400 ℃, the temperature in the hearth can be reduced to the room temperature after being placed and cooled for 2 hours, and how to quickly reduce the temperature in the hearth becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to rapidly reduce the temperature in the hearth;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a fast cooling high temperature tempering furnace, which comprises a furnace body, wherein a hearth is arranged in the furnace body; the heat exchange tubes are positioned in the furnace body and arranged on two sides of the outer wall of the hearth; the furnace body is also provided with a blower, an air inlet pipe and an air outlet pipe; the air inlet pipe is of a Y-shaped structure, one end of the air inlet pipe is connected with the air blower, the other end of the air inlet pipe is connected with the air inlet of the heat exchange pipe, and the air outlet of the heat exchange pipe is connected with the air outlet pipe; the air outlet and the air inlet of the heat exchange tube are both positioned on the rear wall of the furnace body;
that is to say, the heat exchange tubes are arranged at the two sides of the outer wall of the hearth and the gap between the hearth and the furnace body, air is introduced into the heat exchange tubes, and the temperature at the two sides of the hearth is taken away through the heat exchange of the air;
how to lead air into the heat exchange tube, the utility model adopts the structure that the air blower is arranged outside the furnace body and used for absorbing air, the air enters from one end of the Y-shaped air inlet tube and is discharged from the other two ends of the Y-shaped air inlet tube and respectively enters into the heat exchange tubes corresponding to the two sides of the furnace chamber, and the air outlet of the heat exchange tube is connected with the air outlet tube; the air outlet and the air inlet of the heat exchange tube are both positioned on the rear wall of the furnace body, namely the air inlet tube and the air outlet tube are both positioned on the rear wall outside the furnace body, so that the occupied space of the whole device is saved.
The utility model has the advantages that: the utility model relates to a fast cold high temperature tempering furnace carries out the heat exchange through intake pipe to heat exchange pipe with the air through the air-blower, and the air after being heated is through going out the tuber pipe discharge, has realized the quick cooling of furnace boring.
