Portion drives charging crawler belt 12 to be continuously traveling, so that charging crawler belt 12 cycles through feed zone 2, Reheating Furnace Zone 3, cooling bath 4, into
Expect that the cooperation charging crawler belt 12 of roller 11 rotates；Discharging lifting parts are arranged in quenching tank 5, and discharging lifting parts include discharge roller 61, go out
Expect that crawler belt 62 and feeding plate 63, feeding plate 63 are set in the discharge port 60 of discharging lifting parts the upper end, splicing frame 7 is located at feeding plate
63 lower section is equipped with discharging machine M2 in the lifting parts that discharge, and discharging machine M2, which passes through, drives discharge roller 61 to drive discharging crawler belt
62 are continuously traveling with conveying workpieces G dischargings, and improvement is that the entrance side 31 in Reheating Furnace Zone 3 is provided with the first spout of methanol
H1, the methanol persistently from the first spout of methanol H1 can form the fiery curtain H for washing away entire entrance side, the cooling bath 4 after igniting
On charging crawler belt 12 remove cooling bath 4 side be equipped with methanol the second spout H2, the first persistently from the second nozzle of methanol
Alcohol feeds crawler belt 12 after igniting for high temperature drying.
It is known drive mechanism that it is (not shown), which to feed driving section,；Feed roller 11 interval, be set in parallel it is a plurality of, it is a plurality of into
Expect that the rotation direction of roller 11 is consistent；The Control for Kiln Temperature of Reheating Furnace Zone 3 is at 950 degree, and methanol decomposition temperature is at 750 degree；In cooling bath 4
Fill cooling water 40.
The hardening media 50 contained in quenching tank 5 is nitrate solution, and nitrate solution is known and commercially available, it be potassium nitrate with
The mixed solution of sodium nitrite；The interval of discharge roller 61 has been set in parallel a plurality of, and the rotation direction of a plurality of discharge roller 61 is consistent.
The first spout of methanol H1, the second spout of methanol H2 are external to methanol (liquid) head tank (not shown) by flowmeter respectively.
Specific work process is as follows：
Reheating Furnace Zone 3 is warming up to 950 degree and temperature control first, batch chain hoist wheel workpiece G is positioned on feed zone 2,
It opens the first, second spout of methanol and lights methanol, start charging driving section and discharging lifting parts, with charging crawler belt 12, go out
Material crawler belt 62 is continuously advanced, and workpiece G is inputted by the entrance side 31 of Reheating Furnace Zone 3 in Reheating Furnace Zone 3, and workpiece G is being heated
It is exported from the outlet side 32 of Reheating Furnace Zone 3 after reduction in stove area 3, high temperature workpiece G is dropped in quenching tank 5 and is held on quenching tank
On the discharging crawler belt 62 of bottom, workpiece G be elevated from quenching tank bottom after from discharging lifting parts discharge port 60 through under feeding plate 63
It drops down onto in splicing frame 7, thus batch carries out the continuous production of the reduction and quenching of chain hoist wheel workpiece G.
12 1 tunnel of charging crawler belt circulates through feed zone 2, Reheating Furnace Zone 3 and cooling bath 4, and charging crawler belt 12 is cooled down by diagram
The right side of slot 4 enters in cooling bath 4, then behind the left side of cooling bath 4 just removal, the thermal-flame that the second spout of methanol H2 is generated
Charging crawler belt 12 is dried.
Wherein, into methanol fractions uncracked without burning in Reheating Furnace Zone 3, this part methanol high temperature under furnace temperature
Cracking reaction is：It is better than the principle of reduzate according to reducing agent reproducibility
That is reproducibility CO > reproducibilities H2, iron oxide present in workpiece G or ferroso-ferric oxide are preferentially restored with carbon monoxide
Reaction is as follows：
The top of quenching tank 5 is connected with the outlet side of Reheating Furnace Zone 3 is formed as the exhaust portion 8 of intercommunication, in the exhaust portion 8
Top be provided with exhaust pipe 80.
Then enter heating furnace with the uncracked methanol fractions without burning in methanol from the first spout of methanol H1
Vaporization, this part methanol crack under furnace temperature and are formed the barotropic gas for flowing through entire Reheating Furnace Zone 3 completely in area 3, with resistance
Only oxygen-containing air enters from the outlet side 32 of Reheating Furnace Zone 3.
Reheating Furnace Zone, which is flowed through, by means of barotropic gas prevents oxygen-containing air from entering from the outlet side of Reheating Furnace Zone to reach, from
And efficiently avoid the oxidation of workpiece in stove.
The barotropic gas of methanol decomposition soon is the cracking atmosphere of carbon monoxide and hydrogen in stove, just with barotropic gas
To flowing and with workpiece G high temperature contacts in stove, workpiece G then restores under carbon monoxide atmosphere, the carbon dioxide generated and splits
Hydrogen in solution atmosphere still flows through entire Reheating Furnace Zone 3 with forward direction.
Barotropic gas is overflowed through exhaust portion 8 from exhaust pipe 80, the high temperature workpiece that its outlet side 32 is moved out of from Reheating Furnace Zone 3
When G is dropped in quenching tank 5, it is also through exhaust portion 8 from exhaust pipe 80 that the vaporization of 50 heat of hardening media, which is formed by gas blowby stream,
It overflows, and the flowing velocity of barotropic gas is faster than the flowing velocity of gas blowby stream.
Reheating Furnace Zone is connected with quenching tank, and adds the shared exhaust portion with exhaust pipe in connecting portion, can will quench
Upper gas blowby stream and barotropic gas after fiery medium heat vaporization are overflowed, and are altered since the flowing velocity of barotropic gas is faster than
The flowing velocity of air-flow can prevent to alter in reverse flowing of air flows to Reheating Furnace Zone, ensure that the hot temperature stability of Reheating Furnace Zone.
The barotropic gas for flowing and going out from Reheating Furnace Zone 3 is hydrogen and carbon dioxide, and hydrogen and carbon dioxide pass through exhaust
It is simultaneously overflowed from exhaust pipe 80 in portion 8.
