But utility time of this technology is not long at home, in addition, the majority of equipment is two-hand at home, and the craft technology was not introduced with it, so the people's understanding is limited to cast the copper alloy blank using the horizontal continuous casting method, the basic data lacks extremely, the copper alloy materials blank's quality is unstable, more than all, the research to the key component Graphite Crystallizer is insufficient, it affected the application of horizontal continuous casting in a certain.

但这一技术由于国内使用的时间不长，加之国内引进的大多数是二手设备，对工艺技术没有进行引进，因而人们对铜合金带坯的水平连铸生产方法认识有限，基础资料十分缺乏，生产的坯料质量不稳定，特别是对关键部件石墨结晶器研究不够深入，在一定程度上影响了水平连铸方法在铜合金带坯生产中的应用。
