    Straightening can be divided into hot straightening and cold straightening according to the temperature of the straightened part. Thermal straightening is generally carried out at 650 1000 and is only used for medium and heavy plates. Straightening temperature is one of the important parameters for thermal straightening.

    If the straightening temperature is too high, the rolled piece may also be bent due to uneven cooling in the subsequent cooling; If the straightening temperature is too low, the straightening resistance will increase, and the straightening will be difficult. Cold straightening is widely used for straightening various types of steel and steel pipes, and is also used for supplementary straightening of medium and heavy plates. The cold straightening of hot-rolled profiles is carried out after the rolled steel has cooled.

    In order to ensure the quality of straightening and improve the working conditions, the reasonable cold straightening temperature should be lower than 200. When the straightening machine is arranged on the rolling line, it is often too high because the cooling time of the steel is not enough, and the straightening temperature is too high (generally above 200 250) and the expected effect cannot be achieved, which affects the straightening quality. Most steels are straightened only once, and only products that are not easy to straighten and require strict bending require two or more straightenings.

    Straightening methods include pressure straightening, roller straightening (including straight roller straightening and oblique roller straightening), tension straightening, and tensile flexion straightening. The principle of tensile bending straightening is that when the strip is repeatedly bent on a small diameter roller, a tensile force is applied to the strip, so that the strip produces an elastic-plastic extension, thereby straightening the strip. The tensile bending straightening unit is generally used to straighten various strips on continuous operation lines, including high-strength and extremely thin strips.

    This unit is also used for continuous pickling, and after the plate is cooled, it can also be flattened to reduce the thickness difference of the strip and the strip mechanical scale breaking on the straightening line, so as to improve the pickling speed. The straight plate shape of the straightener. In addition, special straightening should be used for some special products, such as the basic types of straightening and their main uses, see the table.

    Cold-rolled sheet or hot-rolled thin-walled and extra-thin-walled pipes are straightened using a rotating drum, etc.

    If the copper tube is thinner, straighten it directly. If you can't straighten it, you can heat it on one side and then straighten it. Of course, the most direct solution is to go to a nearby hardware store. I hope I am of help to you! Yard slipping.

    Brass plate grades should be marked with Y (hard), ZY (medium hard), Ty (extra hard), R (soft), Zr (medium soft), TR (extra soft), etc.

    If the brass plate is too hard or the radius of curvature of the fold is small, cracking and cracking will occur.

    Use anhydrous potassium sulfide A bottle of anhydrous potassium sulfide can be used for a large basin of water, put the copper plate into it, and then the copper plate will become black, and then use a brushed cloth to draw the wire, look at the color of the copper plate, and when it becomes the color you want, you can put it on the water and rinse it clean.

    Use some chemical acid, dilute it, pour it into the soil, and then bury the copper coin in it, about half a month, and you're good to go.

    I don't know if the copper welding rod you said is not the copper brazing, which refers to a welding method heated by flame, with sandblasting, this method is the traditional copper tube material welding, if it is a large plate, this operation may have certain limitations, so I suggest that the dissimilar welding of brass plate and steel plate as you described should be TIG argon arc welding or MIG gas shielded welding, When TIG argon arc welding is used, you can use the brass argon arc welding wire dedicated to Viodin welding (remember that this is not the kind used with sandblasting), DC argon arc welding to avoid zinc burning and smoke during the welding process, which is used in many brass outdoor advertising, and relevant information can be consulted in detail about relevant information.
