一、前言上引连铸无氧铜成套机组的主要备件是连铸结晶器,而石墨模又是构成连铸结晶器的重要部件。石墨材料因其良好的润滑及滑动特性、高的导热率、对熔化金属可沾性小、良好的机械加工性等被广泛用于连铸模具。连铸结晶器中的石墨模,能使上引速度提高、铸件尺寸精确、表面光洁、结晶组织均匀、可直接进行下道工序加工。连铸结晶器的使用工况有如下特点:沿结晶器 I. INTRODUCTION The main spare parts of the continuous casting Oxygen-free copper complete sets are the continuous casting mold, which is also an important part of the continuous casting mold. Graphite materials are widely used in continuous casting molds because of their good lubrication and sliding properties, high thermal conductivity, small contact with molten metal, and good machinability. Continuous casting mold in the graphite mold, can make the speed on the lead, the casting size is accurate, smooth surface, uniform crystalline organization, can be directly under the process of processing. Continuous casting mold usage conditions have the following characteristics: along the mold
