1.冷拉方钢的基本要求有哪些？
1. What are the basic requirements for cold drawn square steel?
冷拉方钢的基本要求：首先是应有足够高的常缓和瞬时高温拉伸强度，以及良好的塑性。其次在持久强度和塑性上也是要非常好的。这样才能够保证在高温环境中，能正常使用，并发挥其应有作用。
The basic requirements for cold drawn square steel: first of all, it should have a sufficiently high tensile strength for normal relaxation and instantaneous high temperature, and good plasticity. Secondly, it is also very good in terms of durability and plasticity. In this way, it can ensure normal use in the high temperature environment and play its due role.
2.生产制造冷拉方钢，具体需要什么？怎样来提高冷拉方钢的韧性？
2. What are the specific requirements for the production of cold drawn square steel? How to improve the capacity of cold drawn square steel?
生产制造冷拉方钢的话，冷拔机和方钢拉模是必须要有的。想要提高冷拉方钢的韧性，简单方法是进行再结晶退火，来达到目的。
For the production of cold drawn square steel, a cold drawing machine and a square steel die are necessary. To improve the transformation of cold drawn square steel, the simple method is to perform recrystallization annealing to achieve the purpose.
3.冷轧方钢的原材料是为什么？对原材料是否有一些基本要求？
3. Why is the raw material of cold rolled square steel? Are there some basic requirements for raw materials?
冷轧方钢的原材料，是热轧圆钢或热轧方钢，具体哪一种，可以根据需要来进行正确选择。而对原材料的基本要求，主要是要避免其有杂质，或是杂质过多，如果有这一情况的话，材料在冷拉后，会出现断裂等质量问题。
The raw material of cold-rolled square steel is hot-rolled round steel or hot-rolled square steel, which one can be correctly selected according to needs. The basic requirements for raw materials are mainly to avoid impurities or excessive impurities. If this is the case, after cold drawing, the material will have quality problems such as fracture.
