Abstract
The technological process of cutting metal with oxygen and ethanol gasoline has ethanol gasoline to replace traditional fuel gas to lower production cost, save energy source and reduce environmental pollution. The technological scheme includes special jetting and absorbing cutting touch, heating the metal in the cut part to burning temperature with the high temperature of the flame, oxidizing the metal with high pressure pure oxygen and blowing out the liquid oxide slag to form cut gap. The fuel is ethanol gasoline containing ethanol in 10-50 vol%. Cutting metal with ethanol gasoline flame has the advantages of level cut, stable and fast cutting speed, simple cutting operation, use safety, etc. and is especially suitable for cutting low carbon steel and low alloy steel.
Description
Technical field
The present invention relates to a kind of process, can be widely used in technical fields such as machinery, shipbuilding, military project, petrochemical industry, mine metallurgy, transportation and energy with the gas flame cutting metal.
Background technology
At present, cutting to mild steel and low-alloy structural steel, the main cutting method that adopts is the oxy-acetylene cutting technique, it is to adopt jet absorption type welding torch, utilizes acetylene and oxygen mix combustion flame to produce high temperature and heats the metal at place to be cut, after METAL HEATING PROCESS arrives ignition temperature point, give high pressure oxygen again, make metal burning produce liquid metal oxide, get rid of the oxide slag by the high-speed cutting oxygen flow simultaneously, thereby form the process of slot.The disadvantage that this process exists is an acetylene gas cost height, produce and use in environmental pollution bigger, store, poor stability etc. when transportation and use.For this reason, people have developed a lot of substitute fuels and its corresponding process, and one of them is an oxygen gasoline cutting technique.But along with the increase of energy demand and the minimizing of worldwide petroleum resources, the mankind are faced with energy crisis again.Therefore, people are actively developing the utilization of the renewable sources of energy, and the use of vehicle-use alcohol gasoline is exactly a model.According to the use experience of vehicle-use alcohol gasoline, development and use oxyethanol gasoline combustion flame has very positive meaning as the preheat flame of metal oxygen cutting.
Summary of the invention
The purpose of this invention is to provide a kind of process, replace traditional fuel gas (acetylene gas, propane flammable gas, gasoline etc.) to reduce production costs, to save the energy, to reduce environmental pollution with ethanol petrol with oxyethanol gasoline flame cutting metal.Technical scheme of the present invention is: adopt the special-purpose cutting torch of jet absorption type, the high temperature that utilizes fuel and oxygen mix combustion flame to produce arrives the metal burning temperature spot with place to be cut METAL HEATING PROCESS, utilize the pure oxygen in high pressure oxidized metal again and blow the liquid oxidatively slag open, form the cutting seam.Fuel used is ethanol petrol.Wherein the volumetric concentration of ethanol is 10%～50%.
Show that according to theoretical calculating of physicochemical enthalpy change when the ethanol volumetric concentration changed, oxyethanol gasoline flame theoretical temperatures can both satisfy the needs of cutting preheating between 4483～4016K between 10%～50%.The flame combustion process stabilization, combustion product pollutes little, and fuel source is extensive, moderate cost.At the different-thickness cut workpiece, can select for use the ethanol petrol of the ethanol content ratio that adapts to cut, to reach best cutting speed and cut quality.For reason given above show with experimental study, adopt oxyethanol gasoline (ethanol volumetric concentration 10%～50%) flame that metal is cut, replace traditional fuel gas (acetylene gas, propane flammable gas, pure gasoline etc.) cutting technique, it is smooth, vertical and the oblique angle error is little, cutting process stable and speed is fast, cutting operation process is simple, advantage such as safe in utilization to have cut surface, can satisfy production requirement fully.In use the oxygen expenditure amount is between oxy-acetylene technology and oxygen process of gasoline, and total production cost is lower than the oxy-acetylene process.Increase along with amount of alcohol, social resources and environmental benefit that this method produces all will obtain fine embodiment, the economic benefit of manufacturing enterprise will be improved along with the expansion of alcohol production process modification and application, and this method is applicable to the craft and the automatic cutting process of mild steel and low-alloy steel.
