Abstract
The utility model relates to a furnace for heat treatment, in particular to a hardening furnace, comprising a furnace body, a feed port, a discharge port and a furnace chamber. The feed port is higher than the discharge port; the furnace chamber is laid horizontally and connected with a rotating mechanism. The hardening furnace has the advantages of long hardening time, high hardening rigidity, uniform heating of objects and stable quality.
Description
Technical field
The utility model relates to thermal treatment used stove, especially quenching furnance.
Background technology
The flue of existing quenching furnance generally be tilt or the middle part have a spiral propeller to make object in flue, move to outlet by inlet, material movement speed is fast, the cool time is not enough, is difficult to reach the index request of quenching.
Summary of the invention
The utility model purpose is to overcome above-mentioned weak point of the prior art, provides a kind of and can reduce object speed of advancement in the quenching furnance, prolongs the cool time, makes the object quenching hardness can meet the requirements of quenching furnance.
The technical scheme that the utility model adopted is a kind of quenching furnance, comprises body of heater, select materials mouth, discharge port, flue, and its structural feature is that the height of opening for feed is higher than discharge port, the flue horizontal positioned, and have a rotating mechanism to link with it.
Because the height of opening for feed is higher than discharge port, and object has the movement tendency that nature becomes flat in rotary course, promptly move to discharge port like this, but because flue is a horizontal positioned, and this motion is very slow, the cool time is long, the quenching hardness height by opening for feed.
The purpose of this utility model can also be able to better realization by following approach: the raised line of along continuous straight runs is arranged in flue, and a plurality of raised lines can be arranged, these a plurality of raised lines can have the 1---12 bar preferably along the circumference uniform distribution.
After raised line had been arranged, raised line played the effect of stirring object in the flue rotation process, object is heated evenly, steady quality.
Advantage of the present utility model is that the cool time is long, the quenching hardness height, and object is heated evenly, steady quality.
