Abstract
The invention relates to a system device for pipeline natural gas in steel plate cutting and application, and belongs to the field of mechanical manufacture. The pipeline natural gas for cutting is prepared by adding a TD rare earth nano polymerizing agent into natural gas as master batch and adding oxygen for adjusting a flame to be blue-white, wherein the inner flame is 5-8 mm in length. According to the system device, the flame temperature can reach 3,400-3,600 DEG C, the pipeline natural gas can be continuously supplied, a steel plate cutting hole is smooth and flat, has few molten slags and can be very easily cleaned, the cutting quality of a workpiece is guaranteed, the production cost is greatly reduced, and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of pipe natural gas steel plate cutting in system and device and application, belong to mechanical manufacturing field.
Background technology
Produce medium-and-large-sized structural member medium plate used in enterprise operation and all need numerical control device oxygen-acetylene cutting, the cutting combustion gas that most enterprise uses is the bottled propane+additive of 50kg (golden flame), Cutting Gases consumption is very large, as I consumes bottled gas more than 2000 bottle in company's year, expense about 1,400,000 yuan, and the gas cylinder that just must more renew after gas in gas cylinder uses, can not cut continuously, affect cut quality and the production efficiency of workpiece, in addition, the handling of gas cylinder, transport and storage take a large amount of manpowers, material resources, place, and there is larger potential safety hazard, simultaneously for military and civilian good sheet material specification, material, the usefulness of various complexity such as hardness to cutting combustion gas proposes higher requirement.
Summary of the invention
The object of the present invention is to provide a kind of pipe natural gas steel plate cutting in system and device and application, the application of this technology improves the cut quality of steel plate, greatly reduces production cost.
technical solution:
The system and device of pipe natural gas in steel plate cutting, comprise: pipe natural gas, TD rare earth nano polymerizer (volatile blue liquid), gas mixer, the pipeline of pipe natural gas is provided with gas source interface, gas source interface is connected with gas mixer air intake, gas mixer gas outlet, by main line, is connected to the burning torch interface of NC flame cutting machine with at least one branch line and antistatic hose.
Installing gas flowmeter, gas gauge on described pipeline, quick action emergency valve, warning device.
Described gas gauge and gas flow meter can regulate according to actual operation requirements.
Described pipe natural gas mixes with TD rare earth nano polymerizer, experimentally obtain: mixed with 7Kg-8KgTD rare earth nano polymerizer by 1000-1200Kg pipe natural gas, the ratio that namely TD rare earth nano polymerizer evaporate into when to be in saturation state in the middle of natural gas is about 6.67 ‰ ~ 8 ‰.
Pipe natural gas is application process in steel plate cutting, cutting technique is as follows, flame adjusting: first light combustion gas, then add oxygen, be adjusted to best neutral flame, flame is blue and white, send sound, internal flame length 5-8mm is good (the thickness adjustment internal flame length according to steel plate), according to the thickness of steel plate and the difference of material, the oxygen operating pressure of adjustment flame is 0.3-0.8 MPa, and cutting oxygen is generally 0.8-1MPa; The pressure of pipe natural gas is 0.15-0.20MPa, TD rare earth nano natural gas cutting gas operating pressure 0.03-0.1MPa during cutting, and flame flame in 10m/s vertical velocity situation must not extinguish or tempering in 10 seconds; Cutting speed 250 ~ 320mm/min.
The combustion gas of inventive pipeline natural gas cutting is the special role utilizing rare earth element, adopt nanometer technology principle that oiliness hydrocarbon molecules structure-activity generation essence is changed, improve energy and the stability of combustion gas, natural gas cutting combustion gas is that masterbatch adds TD rare earth nano polymerizer (the novel new forms of energy Science and Technology Development Co., Ltd. in Baotou product) and makes with natural gas, for steel plate gas flame cuttiug, flame temperature can reach 3400 DEG C ~ 3600 DEG C, pipe natural gas can successive air feed, make steel plate cutting mouth smooth, smooth, molten slag is few, especially easily clear up, ensure that the cut quality of workpiece, because pipe natural gas+TD rare earth nano polymerizer instead of traditional propane+additive (golden flame), production cost is reduced greatly, production efficiency also improves greatly, both Cost comparisons are as follows:
The bottled propane flammable gas price of 50kg is 575 yuan/bottle;
Gas Prices is 2.25 yuan/m3;
1kg bottled propane flammable gas equivalence 1.2m3 natural gas, then: 50 × 1.2m3=60m3, one bottle of propane flammable gas equivalence natural gas is 60m3,
So Gas Prices is 60m3 × 2.25 yuan/m3=135 unit,
One bottle of propane flammable gas being replaced by natural gas reduces expenses is 575 yuan-135 yuan=440 yuan,
2000 × 440 yuan=880000 yuan then can be reduced expenses per year with 2000 bottles of propane flammable gas conversions,
After pipe natural gas replaces bottled propane flammable gas, reduction effect is 440 ÷ 575 × 100%=76.5%.
Accompanying drawing explanation
Fig. 1 is apparatus of the present invention structural representation.
