2020-2-25In fact, the occurrence of slag during laser processing is affect by the processing conditions, the material of the workpiece, and the material thickness. 1. Carbon steel If the processing conditions are set appropriately, slag adhesion will rarely occur. Slag will appear when cutting thick plates, but it is easy to remove. 2. Galvanized steelGet A Quote
2016-8-18Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, which has the chemical formula C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the carbon atoms.
As the gas jet ejects the slag from the bottom surface of the substrate, it produces a cut kerf. Flame cutting is often used for cutting alloy steel such as mild steel and thicknesses up to 40 mm at relatively fast processing speeds.
Cutting or burning of steel, requires an oxygen purity content of 99. When steel is brought to its kindling temperature, the combustion process will initiate when oxygen purity of 99 is added directly to the steel. 6. If when cutting or burning steel using a oxy fuel cutting torch, the cut is lost, why does this happen
R. Evans, in Metalworking Fluids MWFs for Cutting and Grinding, 2012. Carbon steel. Low carbon steels consist primarily of ferrite, which is a solid solution phase of carbon dissolved in alpha-iron, a body centered cubic crystal. Ferrite is the softest phase of steel which is largely responsible for the higher machinability of low carbon steel relative to other carbon and alloyed steels.
2020-3-6Plasma cutting is one of the fastest cutting processes on aluminum, carbon steel, and stainless steel. The process uses hot electrodes to cut through electrically conductive materials. Invented back in 1955 by ESAB, this method can be used for cutting on materials of up to 6 inches thick.
The cutting process is illustrated in Fig. 1. Basically, a mixture of oxygen and the fuel gas is used to preheat the metal to its ignition temperature which, for steel, is 700C - 900C bright red heat but well below its melting point.
Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt. carbon. ... The remaining impurities combine with the lime to form slag, which floats on top of the molten metal where it can be extracted. ... Due to their high wear-resistance and hardness, high-carbon steels are used in cutting tools, springs high strength wire and dies ...
Combined with varying but tiny amounts of carbon, iron makes a much stronger material called steel, used in a huge range of human-made objects, from cutlery to warships, skyscrapers, and space rockets. Lets take a closer look at these two superb materials and find out what makes them so popular
High Carbon Steel Commonly known as carbon tool steel it typically has a carbon range between 0.61 and 1.50. High carbon steel is very difficult to cut, bend and weld. Once heat treated it becomes extremely hard and brittle. This article is the first of a four-part series on the different types of steel.
This process uses gases, propane, and oxygen to produce a controlled flame.Applications are limited to carbon and low alloys steel. These materials can be cut economically, and set up is simple and quick. This process is the best choice for end-users requiring inexpensive cutting of carbon steel

2020-3-4The pressure and flow requirements of auxiliary gas are different for materials with different thickness and different materials. Cutting low carbon steel plate generally USES oxygen. The role of oxygen in the cutting process of carbon steel is to fuel and blow off the molten material. The purity of oxygen is generally higher than 99.5.
Thin cutoff wheels, ranging from 0.030 to 0.045 in. thick, are available in special bond and grain types specifically for use on aluminum, stainless steel, and carbon steel. They can offer fast cutting, long life, low friction, and minimal residual burrs on the material being cut.
Steel with a high alloying content is more difficult to cut than sheet with a low content. Non-ferrous metals Due to the high reflectance and thermal conductivity, aluminum alloys can only be cut in thicknesses up to approx. 30 of the cutting thickness achieved in carbon steel. The cutting
2015-9-1012.5 Iron And Steel Production ... the slag and steel are poured from the furnace by tilting. The production of steel in an EAF is a batch process. ... range from about 1-12 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials ...
2020-1-28A coated electrode is a carbon steel filler rod that has been covered by same form of fluxing material. The coating compositions are applied around a wire to stabilise the arc and improve the properties of the weld metal. ... cutting, and straightening the wire. ... there is the use of a chemically reducing gaseous envelope, which completely ...
Plasma arc cutting is a great process for cutting mild steel plate, offering much higher speeds than oxy-fuel cutting, but sacrificing some edge quality. That is where plasma is tricky. Edge quality has a sweet spot that, depending on cutting current, generally ranges from about 14 inch up to 1.5 inches.
The carbon electrode is a non-filler metal electrode used in arc welding or cutting, consisting of a carbon graphite rod which may or may not be coated with copper or other coatings. The tungsten electrode is defined as a non-filler metal electrode used in arc welding or cutting, made principally of tungsten. Carbon
2020-2-9Recently, it is expected to improve machinability without the addition of lead from the point of view of environmental issues. Nippon Steel Sumitomo Metal Corporation has developed two types of lead-free free-cutting steel. One of the developed steels is for carbon steel for machine structural use with good chip breakability and tool life.
