摘要： A fabrication method of flat-rolled products intended for use in building engineering, made of Zn-Cu-Ti alloy with a chemical composition in accordance with the EN-988 standard, composed of at least two basic steps - continuous casting process of metal strip and not integrated rolling process of finished product in form of sheets, is characterized after casting step of metal strip with a thickness from 4 mm to 16 mm and width from 500 mm to 2000 m the strip is submitted to process of heat treatment in soaking-pit at a temperature of 250 °C to 350 °C for a time of 10 minutes to 48 hours, then is subject to cooling down to ambient temperature, whereafter is heated up to a temperature ranging from 160 °C to 200 °C before starting the rolling operation and is being rolled in at least three roll passes until the finished product is obtained.
In the course of rolling process the Zn-Cu-Ti alloy undergoes dynamic recrystallization at initial rolling temperature ranging from 160 °C to 200 °C, through coagulation of the zinc-titanium particles in Zn-Cu-Ti alloy microstructure achieved on the way of heat treatment.
The reduction ratios in individual roll passes of the rolling process are less than 35 %.
A finished product is susceptible to bending at a temperature > +5 °C.
Zn-Cu-Ti alloy contains from 0,08 wt. % to 0,24 wt. % Cu, from 0,06 wt. % to 0,12 wt. % Ti, not more than 0,015 wt. % Al and rest Zn and also tramp elements Cd, Fe, Pb and Sn.
摘要翻译：用于建筑工程的扁平轧制产品的制造方法，由符合EN-988标准的化学成分的Zn-Cu-Ti合金制成，由至少两个基本步骤组成 - 连续铸造金属带而不是板材成品的一体化轧制工艺，其特征在于，在铸造步骤之后，金属带材的厚度为4mm至16mm，宽度为500mm至2000m，该带材在浸泡过程中进行热处理，在250℃至350℃的温度下进行10分钟至48小时的时间，然后冷却至环境温度，然后在开始之前将其加热至160℃至200℃的温度轧制操作并且以至少三次轧辊轧制直到获得最终产品。在轧制过程中，Zn-Cu-Ti合金在160℃至200℃的初始轧制温度下通过在途中获得的Zn-Cu-Ti合金微结构中的锌 - 钛颗粒的凝结而发生动态再结晶的热处理。轧制过程中单个轧制道次的压下率小于35％。成品易于在> + 5°C的温度下弯曲。 Zn-Cu-Ti合金含有0.08wt。％至0.24wt。％Cu，0.06wt。％至0.12wt。％Ti，不超过0.015wt。％Al和其余的Zn以及杂质元素Cd，Fe，Pb和Sn。
