Abstract
The invention discloses a quenching furnace with a methanol gasifying device, comprising the quenching furnace which is interlay horizontally provided with a mesh belt for conveying workpieces. The quenching furnace is characterized by also comprising the methanol gasifying device; a plurality of pipelines communicated with the quenching furnace are arranged on the top of the quenching furnace; the air inlets of the pipelines are communicated and connected with the methanol gasifying device; in the quenching furnace, fans are arranged beside the air outlets of the pipelines; a main control chamber of the quenching furnace is provided with a CP value display device; and the CP value display device is connected with an oxygen-carbon head. The invention solves the problems of incomplete gasification and decomposition of liquid methanol in the quenching furnace, damage of a furnace body and the workpieces and environment pollution in the prior art and provides the quenching furnace with the methanol gasifying device, thereby enabling the methanol to be gasified and cracked in the methanol gasifying device; and in addition, the invention can well control the flow of gasified methanol, thereby enabling a methanol gas to be uniformly distributed.
Description
Technical field
The present invention relates to a kind of modifying device of thermal treatment process, particularly relate to a kind of quenching furnance with methanol gasifying device.
Background technology
Metal works is heated to a certain proper temperature and keeps for some time, immerse in the quenching media refrigerative metal heat treatmet technology fast immediately.Quenching media commonly used has salt solution, water, mineral oil, air etc.Quenching can improve the hardness and the wear resistance of metal works, thereby is widely used in various workers, mould, measurer and requires the part (as gear, roll, carburized parts etc.) of surface abrasion resistance.Cooperate with the tempering of differing temps by quenching, can increase substantially intensity, toughness and the fatigue strength of metal, and can obtain cooperation (comprehensive mechanical performance) between these performances to satisfy different service requirementss.
In the middle of metal heat treatmet technology, methyl alcohol is one of most important auxiliary material, and the adding mode of methyl alcohol plays crucial effect.The technology that is adopted is that liquid methanol directly uses in quenching furnance in the market.This kind technology can make methyl alcohol decompose in quenching furnance not exclusively, thereby produces carbon distribution, and body of heater and workpiece are caused damage, and contaminate environment.
Existing quenching furnance is in quenching process simultaneously, and methanol gas distributes even inadequately in quenching furnance, and atmosphere is full inadequately, and workpiece does not reach quenching effect preferably when quenching like this.
Summary of the invention
Liquid methanol gasifies decomposition not exclusively in the prior art in quenching furnance in order to solve, produce carbon distribution, body of heater and workpiece are caused damage, and problem of environment pollution caused, the invention provides a kind of quenching furnance, make to enter methyl alcohol gasification cracking in methanol gasifying device and decomposed in the quenching furnance fully with methanol gasifying device, flow that simultaneously can fine control gasification of methanol is evenly distributed methanol gas.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of quenching furnance with methanol gasifying device comprises quenching furnance, is horizontally arranged with the guipure of conveying workpieces in quenching furnance; It is characterized in that: also comprise methanol gasifying device, the top of described quenching furnance is provided with the pipeline in some feeding quenching furnances, and the inlet mouth of described pipeline connects with methanol gasifying device and is connected, in quenching furnance, and the other fan that is provided with in the air outlet of pipeline; Main control room at quenching furnance is provided with CP value display unit, and described CP value display unit is connected with oxygen carbon head, and described oxygen carbon head stretches in the quenching furnance.
Aforesaid a kind of quenching furnance with methanol gasifying device is characterized in that: all be provided with the valve that the control pipeline opens and closes on each pipeline.
The invention has the beneficial effects as follows: 1, the quenching device of gasification of methanol of the present invention, methyl alcohol is gasification cracking in methanol gasifying device, enter and decomposed in the quenching furnance fully, when methyl alcohol uses in quenching furnance like this, can not produce pollution, can not produce carbon distribution yet, prolong the work-ing life of quenching furnance, also improve simultaneously the quality of quenching workpiece, reduced the condemnation factor of workpiece.
2, the present invention is provided with CP value display unit and oxygen carbon head, surveys the CP value by oxygen carbon head, and shows that by CP value display unit the operator can come the flow of open and close valve gate control methanol gas according to the CP value like this.Observe the CP value simultaneously and also can control the time of workpiece blanking, generally in the CP value to set(ting)value 0.25-0.30, after fire is told in the preheating zone, the beginning blanking.
3, the present invention is in quenching furnance, and the air outlet of pipeline is other to be provided with fan, and the methanol gas that pours into like this in the quenching furnance stirs by fan, and it is full that atmosphere is evenly distributed in quenching furnance, and workpiece is better the quench aging fruit like this.
Description of drawings
Fig. 1 is the structural representation of the quenching furnance of band methanol gasifying device of the present invention.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of quenching furnance with methanol gasifying device comprises quenching furnance 1 and methanol gasifying device 3, is horizontally arranged with the guipure 2 of conveying workpieces in quenching furnance 1; The top of quenching furnance 1 is provided with the pipeline 4 in three feeding quenching furnances, all is provided with the valve 5 that the control pipeline opens and closes on each pipeline 4.The inlet mouth of pipeline 4 connects with methanol gasifying device 3 and is connected, in quenching furnance 1, and the other fan 6 that is provided with in the air outlet of pipeline 4; Main control room at quenching furnance 1 is provided with CP value display unit 7, CP value display unit 7 with extend into quenching furnance 1 in oxygen carbon head be connected.Introduce the working process of the quenching furnance of band methanol gasifying device below:
1, by methanol gasifying device 3 with the methyl alcohol cracking that is gasified totally;
2, after being raised to quenching furnance 1 temperature more than 800 ℃, the Open valve 5 cracked methanol gas that will be gasified totally pours in the quenching furnance 1, produces reducing atmosphere in quenching furnance 1.Open fan 6 simultaneously and stir the cracked methanol gas, it is stirred.
3, survey CP value by oxygen carbon head, observe after CP value display unit 7 shows CP values to 0.8, ignition device allows abundant the burning and the full rising of atmosphere in the quenching furnance 1.
4, when showing the CP value, CP value display unit 7 arrives set(ting)value 0.25-0.30, dew point-14, oxygen volt value 1130-1350.After fire is told in the preheating zone, the beginning blanking.
Show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
