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.

開(kāi)坯機(jī)為兩輥水平軋機(jī)，坯料送至軋機(jī)前后，根據(jù)軋制程序表進(jìn)入相應(yīng)的軋槽可逆軋制，并通過(guò)翻鋼裝置將軋件夾緊進(jìn)行翻轉(zhuǎn)。一般軋制5-7道次(多9道次)。

The blooming machine is a two roll horizontal mill, and the billet is sent to the front and rear mills. According to the rolling schedule, the roll is rolled into the corresponding rolling groove, and the workpiece is clamped and turned through the turning device. The general rolling is 5-7 times (up to 9 times).

輥式軋機(jī)生產(chǎn)率可以很高，有的可達(dá)到2000-4000 件/小時(shí)甚至更高，易于實(shí)現(xiàn)自動(dòng)化生產(chǎn)?？傊?，輥式軋機(jī)適用于對(duì)產(chǎn)品精度要求不高，且同時(shí)軋制一個(gè)或幾個(gè)零件的情況。輥式軋機(jī)是三種類型中運(yùn)用多的一種。圓弧式軋機(jī)適用于大批量的為以后鍛造供坯的生產(chǎn)情況。Whatarethecharacteristicsofashortstresslinemill。

The productivity of the roller mill can be very high, some can reach 2000-4000 pieces / hour or even higher, and it is easy to realize automatic production. In conclusion, the roll mill is suitable for the low accuracy of products and rolling one or several parts at the same time. Roll mill is the most widely used in three types. The circular arc mill is suitable for large quantities of production for forging later.
