容器板的热切割往往可以造成热变形，而在工业生产应用中，并不是完全杜绝这类变形影响，而是采取控制及预防措施降低因热切割导致的变形影响。
Container plate thermal cutting, often can cause thermal deformation, and in industrial applications, the deformation is not completely put an end to this kind of influence, take control and prevention measures to reduce the influence of deformation caused by thermal cutting.
　　一、热变形的控制
One, the control of the thermal deformation
　　在数控切割机实际切割过程中，由于对钢板的不均匀的加热和冷却，材料内部应力的作用将使被切割的工件发生不同程度的弯曲或移位-即切割热变形，具体表现是形状扭曲和切割尺寸偏差。由于材料内部应力不可能平衡和完全消除，所以只能采取一些措施来设法减少热变形。
In CNC cutting machine actual cutting process, due to the uneven heating and cooling for steel plate, the role of internal stress will make by cutting the workpiece in different degree of bending or shift - cutting the thermal deformation, specific performance is shape distortions and cutting size deviation. Materials due to the internal stress can't be balanced and fully eliminated, so can only take some measures to try to reduce the thermal deformation.
　　二、钢板表面处理
Second, the plate surface treatment
　　通常钢板从钢铁厂经过一系列的中间环节达到切割车间，在这段时间里，钢板表面难免产生一沉氧化皮。在者，钢板在轧制过程中也产生一层氧化皮附着在钢板表面。这些氧化皮熔点高，不容易燃烧和溶化，增加了预热时间，降低了切割速度，同时经过加热，氧化皮四处飞溅，极易对数控切割机的割嘴造成堵塞，降低了割嘴的使用寿命，所以，在切割前，很有必要对钢板表面进行除锈预处理。

Through a series of steel from the steel mills of the intermediate links to cutting workshop, during this time, inevitably produce a heavy steel plate surface scale. In person, also produced in the process of rolling steel plate in a layer of oxide skin adhere to the surface of steel plate. This oxide coating high melting point, it is not easy to burn and melted, increased the preheating time, reduces the cutting speed, at the same time after heating, scale splash around, easy to cause blockage to CNC cutting machine cutting nozzle, reduces the service life of the cutting nozzle, therefore, before cutting, it is necessary to pretreatment on steel plate surface derusting.
　　三、切割工件前的表面处理及方法
Three, cutting workpiece surface treatment before and methods
　　常用的方法是抛丸防锈，之后喷漆防锈，即将细小铁砂用喷丸机喷向钢板表面，靠铁砂对钢板的冲击力除去氧化皮，再喷上阻燃，导电性好的防锈漆。
After the commonly used method is shot blasting rust, paint rust, the small iron ore to steel plate surface with shot blast machine spray, by the impact of the iron ore to steel plate to remove oxide skin, spray flame retardant, good electrical conductivity anticorrosive paint.
