PS base with aluminum fabrication steps printing PS version of the base with a manufacturing method for a hot slab of aluminum Which is good reputation, the method comprising the steps it is: a, in accordance with the ratio by weight Al: 98, Si: <1.0 , Fe: 0.3 ~ 1.0, Cu: 0.03 Zn,: 0.03, Mg: 0.03, Ti: 0.05 ratio will lower the melting temperature of said alloy composition after mixing 720 ~ 800 ℃ melting conditions; b, and then casting temperature under 690 ~ 750 ℃ ??cast into an alloy ingot; c, so that the alloy ingot at a temperature of 500 ~ 610 ℃ conditions ingot homogenizing annealing; d, and then heated at a temperature of 400 ~ 540 ℃ temperature rolling; e, cold rolling the hot rolled billet from 9.0mm to 0.7mm; f, at a temperature of 300 ℃ ~ 500 ℃ conditions of intermediate annealing 11h, for 1h then cold rolled to 0.15mm, stretched, fully straightening After cutting to be finished. 1, acidic etchants often used sulfuric acid, nitric acid, chromic acid and phosphoric acid. Could easily lead to the presence of nitric acid to generate a large number of hot-rolled tobacco sales center slab, pollute the environment. Coupled with the use of phosphoric acid and sulfuric acid of some sulfur-containing heterocyclic compounds can replace nitric acid, and its luster is very good, the disadvantage is less effective aluminum 2, commonly used in alkaline etchant caustic soda, soda ash and hot rolled trisodium Where to purchase cheap slab, plus a small amount of surfactant. Aluminum plate can be carried out in a general alkaline degreasing agent at a temperature to at least 40 ℃. 3 can also be used hydrogen peroxide and hydrofluoric acid, hydrogen peroxide and acetic acid can also be used. For example, the choice of hydrogen peroxide 45mL / L, glacial acetic acid 80 mL / L to 10 ~ 15s immersion at room temperature. Operation To make a purchase in the hot rolled slab attention to what ventilation | Hot Rolled Plate | Lu being provided by Alcoa Aluminum Co., Ltd. Jinan Lu positive. Jinan, Shandong Aluminum Co. are (www.jnlzly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Lu are aluminum and you hand into the brilliant, for a better future!
