The beam sizes reflected from the concave mirror and the plane mirror are 48 mm and 5.1 mm, respectively. The angle adjusting precision of the plane-concave resonator is 3.18 ′.

Practical application showed that the improved crystallizers solved the problems such as concave big plane and flat side plane of the ingot successfully, and thereby the producing rate was enhanced effectively.

实践证明，对结晶器的改进，成功地解决了扁铸锭大面凹、小面分层的问题，提高了铸锭铣面成品率和热轧成品率。
