Production Flow of Hot Rolled Checkered Steel Plate from China CNBM:
1.The steel raw materials are first melted in an electric furnace. They are subjected to at least 12 hours of intense heat.
2.The mixture is cast into either large rectangular blooms, slabs or bar-like billets, before taking on a semisolid form.
This initial form of steel is then processed via forming operations that include hot rolling into bars, wires, plates and slabs.
3.The steel is subjected to annealing. This is a heat treatment in which the metal is first heated and then cooled under extreme, controlled conditions. The metal is thus treated for internal stresses and is duly softened and strengthened. This processing is also referred to as 'age hardening'. It requires careful monitoring of temperature and heating and cooling times. The aging temperature affects metal properties massively; while lower temperatures cause high strength and low fracture toughness (i.e., more brittle than ductile), higher temperatures result in a tougher material of lower strength (i.e., more ductile than brittle). Rapid cooling can produce a tough steel with no significant loss in strength. The heat treatment given to stainless steel depends on the type and grade of steel being produced.
4. Annealing or the heat treatment can lead to the development of a precipitate, known as scale. The scale can be removed via several methods, such as pickling, (nitric-hydrofluoric acid bath),electrocleaning(application of an electric current, using phosphoric acid and a cathode), etc.
5. Descaling of the material is introduced into the manufacturing process at different times, depending on the type of steel being produced. While the bar and wire forms have to be additionally treated with hot rolling,forging and extruding, the sheet and strip forms go through annealing after hot rolling.
6. Cutting operations in the manufacturing process are essential in obtaining the desired shape and size of the end product. Mechanical cutting involves the use of guillotine knives and high-speed steel blades for blanking (punching out the shape by shearing) and nibbling (cutting out a series of overlapping holes). It is also cut via flame cutting, a process that involves the use of a flame generated by oxygen, propane and iron powder. The plasma jet cutting method uses an ionized gas column to melt and cut the metal.
6. Manufacturing end products involve further shaping via heat-rolling, pressing, forging and extrusion. The material is then joined via welding and given the desired shape.
- Q:Antique store people told me this a few years back and I forgot what you had to the tide, baking soda or ???
- You should leave the vents open summer and winter.You need the air circulation in that area to prevent moisture build up which will occur and cause problemsYou should be well insulated in the ceiling of the third floor not against the roof.If that area was to be finished and lived in then you would insulate the roof and remove the vents and use windows or fans to circulate the air thus preventing moisture build upGood thoughts wise moves.
- Q:I sent my sister to the store to buy spice run for my beer can chicken, and she brought back marinade (not an injectable one) and I'm just wondering why should i do with it? Any ideas?
- appox 3 lbs chicken 2 cups buttermilk 1/4 cup plus 2 tablespoons vegetable oil 4 cloves garlic, Smashed/skins removed 1 TBL pepper 11/2 tsp table salt 2 tsp ground cumin 1 tsp paprika 1 TBL maple syrup (can leave out, maybe sub with honey, I don't always add it in) Directions Place the chicken drumsticks in a large freezer bag, and add the buttermilk and 1/4 cup of oilAdd the garlic cloves,peppercorns, salt, ground cumin, paprika and finally add the maple syrupMix around in the bag and throw in the chickenLeave the buttermilk-marinated chicken in the fridge overnightPreheat the oven to 425°FTake the chicken pieces out of the bag, shaking off the excess marinade, and then arrange them in a roasting pan lined with aluminum foilDrizzle over the 2 remaining TBL oil and sprinkle with more paprikaRoast in the oven for about 30 minutes, or until brown and juices run clearI adapted this from Nigella Lawson's recipe for my family's tasteIt's yummy!
- Q:Paint in my old outdoor patio chairs started to become powdery and it is to be paintedIt is difficult to remove the old pint by sandingCan I just wipe off and apply coat of primer and paint over that?i
- As long as the new paint is compatible with the old paint, you don't need primer Test it on some out of the way spot to ensure it doesn't react badly (I've had old paint soften and wrinkle up under newly applied paint, and it made a mess)You don't need to remove the old paint if it is securely stuck onto the aluminum - that's actually better than primer, so leave it alone Just clean it thoroghly, and if you are really meticulous, lightly scrub any exposed or vulnerable spots with some steel wool or fine sandpaper to break the gloss (if there's any glossy spots left).
- Q:i don't like nuts or dried fruits, but i do like chocolatewill it go well in monkey (pull-apart) bread?here's the recipe:1 cup granulated sugar1 1/2 tsp cinnamon2 cans (16.3 oz each) Pillsbury? Grands!? Homestyle refrigerated buttermilk biscuits1 cup firmly packed brown sugar? butter, melted
- I'm against itThe chips would only really be good if they were all through out and not just at the seamsAnd if you try to fold them into the biscuits you might end up over kneading them and making them toughHere's a recipe that uses cocoa instead of chips and I think it would be more successful in giving you the chocolate touch you crave Chocolate Monkey Bread ■1 3/4 cups granulated sugar ■2 tablespoons unsweetened cocoa powder ■1 teaspoon ground cinnamon ■1 cup butter, melted ■2 12-ounce cans refrigerated biscuits, cut into fourths Preheat oven to 350°Lightly grease/spray a 10-cup Bundt panCombine sugar, cocoa, and cinnamonSet asideDip quartered biscuits into melted butterDredge in sugar mixtureLayer biscuits in panBake for about 1 hourCover with aluminum foil, if necessary, to avoid excess browningCool in pan 10 minutesInvert onto plate and serve.
- Q:Do you put flavoring, or add flaving while roasting, and how long do you roast and at what temperature?
- I tend to like sweet flavorings INGREDIENTS (Nutrition) 1 egg white, lightly beaten 1 tablespoon water 3 cups pecan halves 1/2 cup white sugar 1/2 teaspoon salt 1 teaspoon ground cinnamon 1/2 teaspoon ground cloves 1/2 teaspoon ground nutmeg 1 Preheat oven to 350 degrees F (175 degrees C)Line a baking sheet with aluminum foil 2In a small bowl beat the egg white with the waterStir in the pecans, mixing until well moistened 3In a small bowl, mix together sugar, salt, cinnamon, cloves and nutmegSprinkle over the moistened nutsSpread nuts on prepared pan 4Bake in preheated oven for 30 minutes, stirring once or twiceBe careful not to overcook and burn the nuts.
- Q:I'm looking to buy a set of aftermarket wheels for my LancerI was looking at used ones to save some money, but can't really find any in the dark gray or black that I wantSo I was wondering, could I have aluminum wheels painted?
- Brillo or SOS pads, unlike detergents they have rust inhibitors in them.
- Q:I do not have any casserole pans and no ride to the storeI want to make a tuna casserole, can I spread it out on the sheet pan and bake it that way? I need an answer as soon as possible, thank you in advance!
- do you have aluminum foil? make a box shape of double foil and put it on the sheet pan and put your tuna casserole in that.
- Q:use the following balanced chemical equation to calculate: (.?3CuCl2 + 2Al -gt; 3u + 2AlCl3?Mass of beaker:54.31gMass of aluminum foil:0.40gMass of beaker + copper + h2O:54.85g use the following balanced chemical equation to calculate:(.)a) IDENTIFY THE LIMITING REAGENT AND THE EXCESS REAGENT IN THIS REACTION.wHAT VISIBLE EVIDENCE IS THERE TO CONFIRM YOUR IDENTIFICATION?for this one is it something like that?Firstly, we would convert the grams of each reactant to moles using: Moles mass (g)/ molar mass (g/mol): M Cu 63.55, M CI 35.45270.9, M CuCI2 134.45g/mol Moles CuCI2 45.85g/ 134.45g/mol 0.339 moles (in reaction mixture) Moles Al 0.40g/ 26.98g/mol 0.015 moles (in reaction mixture)Dividing moles of each reactant by its coefficient: CuCI2 134.45g/moles/ 3 44.817Al 0.015 moles/ 2 0.008CuCI2 has the larger number so it is present in excessis that truee??im confused and it due tomorrow!!;(and what about the percentage yield of copper ??
- Sorry that I did not see this question any earlierYour data is confusingFirst, is the reaction a solution of Copper (II) chloride or solid CuCl2? Should the balanced equation be: 3 CuCl2 (aq) + 2 Al (s) - 3 Cu (s) + 2 AlCl3 (aq)? Mass of beaker + copper + h2O:54.85g Where did the water come from? If it is from the aqueous solution, why was the metallic Copper not dried? Exactly how much CuCl2 was used (or how much of what concentration of CuCl2 solution was used)? 45.85 g of CuCl2 or of solution? You have the right idea of how to calculate the number of moles of the reactantsIf all of the Aluminum foil reacts, it was not in excess (so the CuCl2 must be in excess)For every 2 moles of Al that reacts, you should get 3 moles of Cu metal0.40 g / 26.98 g/mol 0.0148 moles of AlThis should make 0.0222 moles of Cu or 0.0222 63.55 g/mol 1.41 grams of Copper as the theoretical yield.
- Q:When I was younger, we always did quot;hoboquot; meals at camp every summerThey are foil packets you cook on a campfire and they are delicious! I want to cook some in my oven tonight but I need to know the temperature and how long to cook themI am cooking the meat separately, so I am just going to have veggies in the packets.
- 350 for an hourtoss your vegies with some oil and herbs, salt and pepperPut longer-cooking veglike potatoes on bottom of your packets so they'll self-baste.
