Il irrumblat kiesaħ dejjaq strixxa huwa magħmul ta ' irrumblat sħun ċinturin dejjaq azzar , u a dejjaq strixxa azzar li jkollok a ħxuna ta' mhux aktar 4 mm u a wisa ' ta' mhux aktar minn 600 mm huwa prodott minn a kiesaħ irrumblar metodu.
Il- proċess tradizzjonali ta' kiesaħ irrumbljat strixxa produzzjoni jikkonsisti minn diversi passi ta' pickling, rolling, ittemprar, qtugħ, estinzjoni u lest prodott ippakkjar. In the current cold-rolled narrow strip steel industry, the level of equipment in each process is uneven, and there are advantages and disadvantages, but in general, the level of production equipment of broadband steel is quite different. Madankollu, il- produzzjoni karatteristiċi ta ' irrumblati kesħin dejjaq strixxa azzar jiddetermina li it-tagħmir il-livell ma jkollux bżonn biex ikun għoli bħala il - broadband azzar produzzjoni tagħmir. Kif biex tiżgura il-produzzjoni tagħmir livell ta ' irrumblat kiesaħ dejjaq strixxa azzar għandu ċerti karatteristiċi meta mqabbla ma' illum's ambjentali protezzjoni u kwalità.
2.1 Pickling produzzjoni proċess tagħmir In the past, the box type sulfuric acid pickling method was widely used in the production of cold rolled high quality narrow strip steel. After several years of development, the continuous pickling line line been widely used in in diversi cold-rolled narrow strip steel production plants, but the equipment level is generally back, and the current production line needs to solve the following Problemi.
(1) Trattament ta ' aċidu ċpar u skart aċidu. Aċidu ċpar mhux biss żidiet aċidu konsum, corrodes impjant u tagħmir, iżda ukoll kordi il-wiċċ ta ' azzar strixxi li mhumiex trasportati fi ħin% 2c u puts a lott ta ' pressjoni fuq l-ambjent .
(2) A pickling tisħin apparat. Most manifatturi consider the investment cost to use steam as a heat source to directly or indirettament heat the acid solution, lack the acid temperature control system, affect the stability of the pickling quality and the production capacity and waste energy. It is recommended use pickling temperature control equipment.
(3) Pickling speed. In the pickling line, the speed can be adjusted. As the pickling is extended, the acidity decreases, the ferrous ion increases, the ferrous ion increases, and the pickling time must be prolonged. To avoid the occurrence of acid or acid in the surface of the steel strip, waste acid. It is recommended to use frequency conversion technology in the production line to make the continuous pickling speed turn into adjustable speed.
Għal il-futur żvilupp, after the hot-rolling tropical production line, multi-party capital cooperation should be adopted to build a technologically advanced tower-type continuous pickling line with the same level of broadband, and the waste acid liquid should be reduced by hydrochloric acid regeneration technology to replace the current equipment. Il livell is ġeneralment lura, with a wide range of points, a wide range of pollution, and a relatively concentrated continuous pickling line. The cold-rolled strip mill directly uses the pickled rust-proof strip steel after pickling, thus completely solving the environmental impact of the cold-rolled strip mill, reducing the production cost and making the production environment truly clean.
