技术领域technical field
本发明属于金属塑性加工领域，具体涉及轧制中对金属复合板补温的装置及补温方法。The invention belongs to the field of metal plastic processing, and in particular relates to a temperature supplementing device and a temperature supplementing method for a metal composite plate during rolling.
技术背景technical background
随着我国经济水平和国家综合实力的不断提高，各个行业对金属材料性能的要求不断提高，单一的金属材料、合金材料已经很难满足现代化生产对材料性能的要求，多金属复合材料是在一层金属上复加另一种或多种金属的板带，可以发挥金属材料各自的优势，实现各金属材料资源的最优配置，节约贵重金属材料，实现单一金属不能满足的性能要求。With the continuous improvement of my country's economic level and national comprehensive strength, the requirements of various industries for the performance of metal materials continue to increase. It is difficult for a single metal material and alloy material to meet the requirements of modern production for material performance. Adding another or more metal strips on the layer metal can give full play to the respective advantages of metal materials, realize the optimal allocation of metal material resources, save precious metal materials, and achieve performance requirements that cannot be met by a single metal.

The main methods of compounding are explosive compounding method, rolling compounding method and so on.
板材加热是金属复合板生产的第一道关键工序，板材加热质量的好坏,直接影响到轧制过程能否顺利进行。终轧温度是轧制过程中影响产品和力学性能的重要参数。影响终轧温度的因素有待温时间、出炉温度、室温、材料进给速度等。Plate heating is the first key process in the production of metal clad plates. The quality of plate heating directly affects whether the rolling process can be carried out smoothly.

金属复合板材在轧制过程中，由加热炉出料到进入上下轧辊前的时间内，由于金属复合板材表面空气对流和热辐射会造成热量散失和温度下降，这一状况会影响终轧温度，最终影响产品尺寸精度以及产品组织性能，影响产品的最终质量。During the rolling process of the metal composite sheet, during the period from the discharge of the heating furnace to the time before entering the upper and lower rolls, due to air convection and heat radiation on the surface of the metal composite sheet, heat loss and temperature drop will occur, which will affect the final rolling temperature. It will ultimately affect the dimensional accuracy of the product and the organizational performance of the product, as well as the final quality of the product.
