在铸造开始时，铸造结束时和生产过渡件时，在连续铸造机中的工艺工程措施

Process engineering measures in a continuous casting machine at the start of casting, at the end of casting and when producing a transitional piece
Abstract:
A method for operating a continuous casting machine (1) at the start of casting, at the end of casting and when producing a transitional piece (21) for improving the quality of the ends of the strand (16, 18), and protecting the machine from damage. At the start of casting, perform the following additional method steps: recording a position of the beginning of the strand (16) in the strand guide (4); after the beginning of the strand (16) and after an upper end (17a) of the beginning region of the strand (17), has passed a pair of adjustable strand guiding rollers (5) adjusting the roller pair to touch the strand (2); cooling the beginning region of the strand (17) by the cooling nozzle (10) delivering an amount of coolant Q less than a nominal amount of coolant Qnom to the beginning region of the strand (17); and cooling the main part of the strand (20) by the cooling nozzle (10) delivering an amount of coolant Q that is substantially equal to Qnom to the main part of the strand (20).
Abstract(Chinese):

一种在铸造开始时，在铸造结束时和当制造用于提高股线（16,18）的端部的质量的过渡件（21）时操作连续铸造机器（1）的方法，并且保护 机器受损。 在铸造开始时，执行以下附加的方法步骤：将股线（16）的开始位置记录在股线引导件（4）中; 在股线（16）开始之后，并且在股线（17）的开始区域的上端（17a）之后，已经通过一对可调整的线引导辊（5），调节辊对以接触股线（2 ）; 通过冷却喷嘴（10）冷却所述绞线（17）的开始区域，所述冷却喷嘴将少于冷却剂Qnom的标称量的冷却剂Q的量输送到所述线材（17）的开始区域; 并且通过冷却喷嘴（10）冷却所述绞线（20）的主要部分，所述冷却喷嘴向所述绞线（20）的主要部分输送大致等于Qnom的量的冷却剂Q。
