Abstract
A technology for cutting metal, especially the low-carbon steel and low-alloy steel, by oxygen-alcohol flame instead of oxyacetylene flame is disclosed. Its advantages are high safety,and no environmental pollution.
Description
One, technical field
The invention belongs to the Machining Technology field, be specifically related to a kind of process of Metal Cutting.
Two, background technology
At present, cutting to metal, all adopt traditional jet absorption type welding torch, utilize the burning of acetylene gas (gasoline, propane etc.) and oxygen mix, produce high temperature and heat place to be cut metal, with METAL HEATING PROCESS behind ignition temperature point, give high pressure oxygen again, make metal burning produce liquid metal oxide, get rid of slag by the high-speed cutting oxygen flow simultaneously, thereby form the process of slot.Its disadvantage is an acetylene gas cost height, and environmental pollution is bigger in production and use, is storing, transporting and using poor stability.Though other combustion gas, belong to and consume the disposable energy in the energy resource consumption, improve to some extent in price and the security than acetylene gas, do not have recyclability.
Three, summary of the invention
The purpose of this invention is to provide a kind of process with oxyethanol flame cutting metal, adopt ethanol to replace traditional fuel gas (acetylene gas, propane flammable gas, gasoline etc.) that metal is cut, to reduce production costs, energy savings reduces environmental pollution.
The technical solution used in the present invention is: with the process of oxyethanol flame cutting metal, be to adopt jet absorption type welding torch, utilize the burning of fuel gas and oxygen mix, produce high temperature place to be cut METAL HEATING PROCESS is arrived the metal burning temperature spot, utilize the pure oxygen in high pressure oxidized metal and blow the liquid oxidatively slag open, form the cutting seam.Used fuel gas is an ethanol.
The inventive method can satisfy production requirement fully, and is not only simple to operate, safe in utilization, do not pollute, and cheap, wide material sources, in use oxygen demand is will oxygen little and that acetylene gas consumes than gasoline and propane flammable gas approaching, and production cost reduces greatly.Can replace the oxy-acetylene cutting technique of use at present, and be applicable to the cutting of mild steel and low-alloy steel.
Four, description of drawings
Accompanying drawing is production technology figure of the present invention.
Five, the specific embodiment
At first ethanol pipe joint 7 is connected ethanol bottle 1 exit, and is connected on the cutting torch 14, ethanol pressure detecting table 3 is arranged on the ethanol bottle 1 with ethanol carrier pipe 12; Ethanol is entered 3/4 long-pending back of bottle by inlet 6 fillings be pressurized to 0.15Mpa by pressurizing piston 5.Oxygen pressure regulator 11 is loaded on the exit of oxygen cylinder 2, by technological requirement oxygen pressure regulator 11 and cutting torch 14 is linked up, form the complete cutter sweep of a cover with oxygen conveying pipe 13.The open degree of opening oxygen switch valve 8 subsequently in order respectively and regulating oxygen pressure regulator 11, the pressure of observation oxygen high pressure gauge 9 and low-pressure meter 10 is just known the high-pressure gas pressure in the oxygen cylinder, and the low-pressure gas pressure of the cutting torch that send.Open ethanol bottle controlled valve 4, open ethanol switch valve 15, regulate ethanol stream adjustable valve 16.The right hand is held the handle 19 of cutting torch 14, make cutting torch 14 keep horizontal level, left hand is opened oxygen flow control valve 17 and ethanol stream adjustable valve 16 slightly, the cutting torch 20 of hearing cutting torch has the sound of ethanol and oxygen mixed gas ejection and has ethanol liquid to flow out, this moment the igniter of lighting is placed the exit of cutting torch 20, mist burns at once, the open degree of appropriate regulation oxygen regulating valve 17 and ethanol control valve 16 again, make the burned flame energy rate reach the requirement of corresponding cutting thickness of slab and when being neutral flame, can carry out cutting operation.When flame heat place to be cut metal arrives metal burning point temperature, open cutting oxygen valve door 18, the pure oxygen in high pressure that utilizes cutting torch 20 to spray flows burning and blows oxidizing slag open, forms slot.
The relative gasoline of the heat that ethanol produces in combustion process, calorific value is lower, be generally 61%, therefore under the situation of the identical thickness of slab of cutting, in preheating and cutting stage, it is big that relative consumption is wanted, and this just needs the amount of alcohol fuel to want big, therefore the rifle body that is used for the ethanol cutting is structurally different with the gasoline burning torch, and the ethanol passage will strengthen.The purity of ethanol is a principal element of influence cutting, and purity reduces, and will have water and together take out of from burning torch, reduces the temperature that adds thermal-flame and to the heating process of steel plate, thereby reduces cutting speed.Experiment shows that purity drops to 98.5% cutting process and will be difficult to carry out.
Claims (2)
1, a kind of process with oxyethanol flame cutting metal, be to adopt jet absorption type welding torch, utilize the burning of fuel gas and oxygen mix, produce high temperature place to be cut METAL HEATING PROCESS is arrived the metal burning temperature spot, utilize the pure oxygen in high pressure oxidized metal and blow the liquid oxidatively slag open, form the cutting seam, it is characterized in that: used fuel gas is an ethanol.
2, the process with oxyethanol flame cutting metal according to claim 1, it is characterized in that: the purity of used ethanol is higher than 98.5%.
