Baotou steel belt semicontinuous pickling operation profile

Play clad steel belt and a half continuous pickling continuous pickling operation introduction this way is to use a half also known as push ( Or push-pull type) Acid pickling line. Its technological process is: with steel plate after uncoiling decoiler, then enter the straightening machine straightening steel strip, strip pass unit, to ensure the straightening steel strip by pickling groove on the surface of the acid to remove the oxide iron, then into the cleaning tank, to remove the strip from out of the residual acid in the acid tank, then through hot air drying device to its surface drying, finally after cutting edge, cut the turn tail and reel curled up strip coil, FIG. 3 3 and a half for continuous pickling line diagram. Generally half of the continuous pickling line head without guillotine shears, this is because the front end of the hot rolled strip steel & other; The tongue & throughout; Can smoothly through the unit. But within each acid tank and acid tank equipped with transmission between the puller roller, roll gap is adjustable, the puller roller to strip end can be introduced into the puller roller accurately. If half two strip continuous pickling pickling at the same time, so in the acid tank will be equipped with strip groove, in order to make sure a few strip steel in acid tank can be normal operation in parallel. Semi continuous pickling line because it has no head shears, descaling machine ( Or pull machine) Live, welding machine, make ready ( Or looping pit) Equipment, and the number of roller conveyer and the puller roller is far less than the continuous pickling line, mechanical equipment of the unit to a minimum, so its cost is cheaper. Compared to the continuous pickling line, continuous pickling half of simplified equipment, greatly shorten the length of the unit, reducing the area, improve the productivity of the unit, and simplify the operation, the production of strip steel varieties are more at the same time. The main disadvantage of semi continuous pickling line is not and coil. So for heavy plate using large volumes of abrasion, galvanized factory is not recommended in this unit. When the production capacity of small or medium capacity of abrasion, can use continuous pickling and a half.
