軋制技術(shù)的有關(guān)問(wèn)題:

般在板邊緣較薄，扎或縱厚度偏差就叫做板凸度。如果板凸度足夠大，板厚偏差可以達(dá)到一定值，以至于鋼板不適用于在嚴(yán)格要求板厚精度的場(chǎng)合。當(dāng)厚度偏差增大（在板寬方向上厚度不同）導(dǎo)致在材料設(shè)計(jì)后產(chǎn)品損失中應(yīng)考慮增加板厚邊緣。

It is thinner on the edge of the plate, and the deviation of the ligation or longitudinal thickness is called the plate convexity. If the plate convexity is large enough, the thickness deviation of the plate can be reached to a certain value so that the steel plate is not suitable for the situation where the thickness of the plate is strictly required. When the thickness deviation increases (the thickness is different in the width of the plate), the thickness edge of the plate should be added to the loss of the product after the material is designed.

據(jù)說(shuō)在14世紀(jì)歐洲就有軋機(jī)，但有記載的是1480年意大利人達(dá)·芬奇（Leonardo da Vinci）設(shè)計(jì)出軋機(jī)的草圖。1553年法國(guó)人布律列爾(Brulier)軋制出金和銀板材,用以制造錢(qián)幣。此后在西班牙、比利時(shí)和英國(guó)相繼出現(xiàn)軋機(jī)。

It is said that there are rolling mills in Europe in the fourteenth Century, but it is recorded that in 1480, Leonardo Da Vinci (Italian Italian designer Da Finch) designed the draft for rolling mills. In 1553 the French law Adler cloth (Brulier) rolled gold and silver plate, used in the manufacture of coins. Since then, rolling mills have been rolled out in Spain, Belgium and Britain.

軋制時(shí)毛坯的位置固定，因此不需設(shè)置側(cè)向支撐毛坯的導(dǎo)向尺?？傊m用于軋制復(fù)雜外形結(jié)構(gòu)，精度要求高，零件品種變換很多的情況。但其行程大小受到限制，所以，變形程度也受到影響，同時(shí)，板式軋機(jī)有空行程，故影響到生產(chǎn)率和變形程度都不能很大。

The of the blank is fixed during rolling, so there is no need to set the guide bar of the side supporting blank. In short, it is suitable for rolling complex shape structure with high accuracy and many varieties of parts. But the stroke size is limited, so the degree of deformation is also affected. At the same time, the plate mill has an empty travel, so the productivity and deformation can not be very large.
