What is the substance which reacts with unwanted impurities in ores to form a fusible mass which can easily be removed?
It is called Flux. It forms 'slag' with the impurities, which are then removed.
What is purpose of the flux in welding?
Flux is used to protect the weld from the atmosphere. Flux produces a gas shield over the liquid portion of the weld during the welding process as the electrode is used. The flux then forms a protective layer over the weld called slag. Flux also acts as a deoxidizer, pulling oxygen and nitrogen from the weld pool to the surface, preventing porosity. There are many other and much more technical reasons that involve chemistry of the weld metal, arc characteristics, and mechanical properties of the finished weld.
How is slag formed?
A slag is a girl who sleeps around with girls and wears revealing clothes and wears padded push up bras. They two time and wear a lot of make up to get attention form males, males often think of them as easy and have very little respect for them and only use them for sex and blow jobs. e.g. ramanSo if you do the above you are classified as a slag
Why is limestone add to blast furnace?
To remove impurities, mainly sand ( silicon dioxide). It is sometimes reflerred to as a 'flux'. The limestone undergoes thermal decomposition. CaCO3 = CaO + CO2 The CO2 reacts with the coke to produce carbon monoxide CO2 + C = 2CO The Carbon monoxide reduces the iron ore ( iron oxide) to iron Fe2O3 + 3CO = 2Fe + 3CO2 The iron is tapped off at base of the furnace. The CO2 recircluates to form more carbon monoixide. The Iron ore contains a number of impurities , notably sand (silicon dioxde ; SiO2) These impurities react with calcium oxide (CaO) produces from the thermal decomposition of ;omestone, to form 'slag'. CaO + SiO2 = CaSiO3 (calcium silicate (Slag)). Since tons of slag is produced it is used to make 'breeze blocks' for building and road surfaces.
What are the proess of iron production in blast furnace?
First we add the basic iron production elements (i.e, limiston,coreand processed iron e.g hematite,Fe2O3 ) the coke is react with oxygen and form crbone monoxide the limestone decomposed to CaO and carbon dioxide,CO2 carbondioxide,CO2 react with Fe2O3 to form Fe and CO CaO (reaction flux) react with almunia and silica form slag the Fe is removed as a molton ways below blast furnace and sage is removed anather ways,THANK YOU FOR READ
What is welder slag?
Welder slag is a byproduct resulting from the welding process, often forming a layer on top of the welded joint. It consists of the residue from the flux used in the welding rod or wire, which helps protect the weld pool from impurities and contaminants while it cools. Slag is typically removed after welding to inspect the quality of the weld and ensure proper fusion.
What do mean by flux and slag?
In (SMAW) Shielded Metal Arc Welding 'stick welding': Flux is the substance added to to molten metals to bond with impurities that can be readily removed. Slag is the waste material which is removed.
What is a common flux in a blast furnace?
Limestone, dolomite, BOF slag, electric furnace slag, olivine
What is the substance which reacts with unwanted impurities in ores to form a fusible mass which can easily be removed?
It is called Flux. It forms 'slag' with the impurities, which are then removed.
Slage inclusion welding defect?
Slag is normally seen as elongated lines either continuous or discontinuous along the length of the weld.
What is slag from welding?
Slag is the residue left on a weld bead from the flux. It shields the hot metal from atmospheric contaminants that may weaken the weld joint. Slag can also be globules of molten metal that are expelled from the joint and then re solidify on the metal surface. in either case, they are usually chipped away with a slag hammer.
What is added to remove rocky waste and it forms molten slag?
Limestone
What was the flux during Henry VIII?
The flux was generally a form of Dysentery.
What is a welding chipping hammer?
A welding chipping hammer is a hand held tool, like yourself. It is used for removing slag after the SMAW or flux core process.
What are Three functions of the electrode covering in manual metal arc mma welding?
3 FEATURES OF FLUX CORED ELECTRODES Flux cored electrodes combine the advantages of several of the welding processes we have discussed earlier. As with coated electrodes, the flux improves the weld metal chemi- cal composition and mechanical properties. As in gas metal arc welding and submerged arc welding, productivity is increased because the electrode is continuous. 7.3.0.1 Flux cored electrodes may be used for welding carbon steels, low alloy high strength steels, and the high strength quenched and tempered steels. They are also used for welding stainless steels and abrasion resistant steels. These will be covered in subse- quent lessons. 7.3.1 Functions of the Flux Ingredients - As with coated ingredients, each manufac- turer has his own formulas for the flux ingredients. The composition of the flux core can be varied to provide electrodes for specific applications. 7.3.1.1 The basic functions of the flux ingredients are: a) Deoxidizers and Denitrifiers - Since nitrogen and oxygen can cause porosity or brittleness, deoxidizers such as manganese and silicon are added. In the case of self-shielded electrodes, denitrifiers such as aluminum are added. Both help to purify the weld metal. b) Slag Formers - Slag formers such as oxides of calcium, potassium, silicon or so- dium are added to protect the molten weld puddle from the atmosphere. The slag aids in improving the weld bead shape and "fast freezing" slags help hold the weld puddle for out-of-position welding. The slag also retards the cooling rate, especially important when welding the low alloy steels. c) Arc Stabilizers - Elements, such as potassium and sodium, help produce a smooth arc and reduce spatter. d) Alloying Elements - Alloying elements, such as molybdenum, chromium, carbon, manganese, nickel, and vanadium, are used to increase strength, ductility, hardness and toughness. e) Gasifiers - Minerals, such as fluorspar and limestone, are usually used to form a shielding gas in the self-shielded type wires.
What type of flux is used for welding copper?
The primary purpose of flux is "to clean". It mixes with the elements in the molten puddle and removes impurities. As it cools it floats to the surface and creates the slag which prevents Oxygen from attacking the Iron.
