彩涂镀锌板的三种切割工艺


彩涂镀锌板是一种长期不易生锈的钢板,因为它是在外部镀锌以保持内部碳钢。虽然这种板材比普通的碳钢板材稍贵一些,但从整个产品的成本来看,它仍然具有成本效益,因为不需要后续的喷涂等工艺来防锈。

 
但经过激光处理后,彩涂镀锌板的状态有所不同。从辅助气体的角度看,彩涂镀锌板的切割一般有三种工艺,即空气切割、氧气切割和氮气切割。气割:优点是加工成本很低。只需考虑激光器和空压机的电费。辅助气成本不高。但是,薄板上的切割力可以抵抗氮气切割。这是一种经济有效的切割方法。
 
但是,阻塞段的缺陷也很严重。最重要的是,气切段会产生底部毛刺,激光加工的产品必须经过过去的毛刺等二次加工,不利于产品的整个生产周期。其次,空气切割的部分被简单的熏黑,影响产品质量。
 
因此,热浸镀锌板激光加工的优势如果不进行后续处理是无法显现的,因此很多企业在彩涂镀锌板的加工中都不愿意选择气割。我们也知道这三种切割技术的优缺点。气割技术现在很少使用。我们使用它的时候,还需要结合自己的实际情况。
Coloured galvanized sheet is a kind of steel sheet which is not easy to rust for a long time because it is galvanized on the outside to maintain the inner carbon steel. Although this kind of sheet is slightly more expensive than ordinary carbon steel plate, it is still cost-effective in terms of the cost of the whole product, because there is no need for subsequent processes such as spraying to prevent rust.
However, after laser processing, the condition of color-coated galvanized sheet is different. From the viewpoint of auxiliary gas, there are generally three kinds of cutting processes for color-coated galvanized sheet, namely air cutting, oxygen cutting and nitrogen cutting. Air cutting: The advantage is that the processing cost is very low. It only needs to consider the electricity cost of the laser and the air compressor. There is no high cost of auxiliary gas. However, the cutting power on the thin plate can resist nitrogen cutting. It is an economical and efficient cutting method.
However, the defects in the blocking section are also significant. Above all, the bottom burr will occur in the section cut by air, and the products processed by laser must be processed through the past burr and other secondary processing, which is not conducive to the whole production cycle of the product. Secondly, the section cut by air is simply blackened, which affects the quality of products.

Therefore, the advantages of laser processing of hot-dip galvanized sheet can not be shown without follow-up treatment, so many enterprises are reluctant to choose air cutting in the processing of color-coated galvanized sheet. We also know the advantages and disadvantages of these three kinds of cutting technology. Air cutting technology is seldom used nowadays. When we use it, we still need to combine our actual situation
