Abstract
The invention relates to a heat treatment method of a metal article, and provides a rotatable cartridge heater which is internally provided with a heating channel, a second-order metal article is placed into the channel from an injection port at one end of the heating channel, moves to a discharge port at the other end through the heating channel and is heated and turned over; after the metal article is heated to the set temperature, the metal article is caused to move to a cooling tank to be cooled from the discharge port in a quantitative transmission mode, and then is collected; therefore, by utilizing the mode of charging from one end and discharging from the other end of the metal article, all sheet metal receive the same heating conditions by the whole heating channel and are quantitatively transmitted to the cooling tank to receive uniform cooling effect to cause each metal article in each batch to be controlled in stable heat treatment conditions and ensure the quality of products after heat treatment.
Description
Technical field
The present invention relates to a kind of heat treating method of metal objects, relate in particular to a kind of each batch metal objects thermally equivalent that makes and handle, guarantee the heat treating method of the metal objects of constant product quality.
Background technology
As small-sized metal objects such as chain sheets, in manufacturing processed,, must change its physical properties by the thermal treatment means usually for improving its intensity, with the chain sheet is example, the heat treatment mode of this chain sheet generally is that multi-disc chain sheet is put into a cartridge heater, relends the heat effect by the heating unit of cartridge heater periphery, after these chain sheets are heated to predetermined temperature, make these chain sheets pour out to cooling tank again and lower the temperature, afterwards, again these cooled chain sheets are collected by cartridge heater.
But these chain sheets are to be inserted by the material mouth of this cartridge heater one end, after waiting to finish heating schedule, be still by the material mouth of the mutually same end of this cartridge heater and pour out, therefore, these chain sheets stir though cartridge heater by the drive unit driven rotary, makes the chain sheet be positioned at cartridge heater in the process of this cartridge heater internal heating, but each chain sheet still only stirs at the section place of originally inserting the cartridge heater place, till heating schedule finishes.Yet, the heat effect that heating unit provides of cartridge heater periphery, cartridge heater be not each section be to be equal temperature state, therefore, each batch is inserted in the multi-disc chain sheet of cartridge heater internal heating, in the process of this cartridge heater internal heating, have the uneven situation of being heated, and these chain sheets are together to be introduced in the cooling tank to lower the temperature, the uneven situation that cools is arranged, so that the quality after each batch chain sheet thermal treatment can't obtain preferable control.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcome the above-mentioned defective that prior art exists, and provide a kind of heat treating method of metal objects, make each batch metal objects in whole heat treatment process, can stably control its heat-treat condition, guarantee the good quality of product after the thermal treatment.
