AI Technical Summary
Technical Problem
After plasma cutting, the slag adheres to the plate and becomes integrated with it. Existing technologies cannot effectively reduce the amount of slag residue, resulting in high slag removal costs and poor results.
Method used
By adjusting parameters such as the deflection angle of the plasma cutting torch, the cutting airflow, the cutting current, the cutting height, and the cutting speed, an expression for the cutting point temperature is established, enabling the molten slag to melt along with the material during the cutting process, thereby reducing slag residue.
Benefits of technology
It effectively reduces the amount of slag adhering to the plate, lowers the cost of slag removal, and improves the slag removal effect, making the slag easier to remove.

Abstract
本申请公开了一种抑制等离子切割板材坡口挂渣的工艺方法和装置，属于切割工艺领域，该方法包括：步骤1：将板件固定摆放到切割台上；步骤2：确定等离子割炬的偏转角度、切割速度、切割电流、切割气流和切割高度参数；切割速度的推导过程为已知偏转角度和切割厚度,建立同一切割竖线上下端面点的坐标关系式以及切割点温度表达式，设置同一切割线上的各点材料同时融化，得到切割速度理论值；步骤3：将切割参数输入到等离子切割装置中，对板件进行切割。通过本申请中的技术方案，实现了对切割面形状的调整，减小了熔渣粘附在板件的量；配合调整切割工艺参数，使等离子割炬在移动的过程中，熔渣材料快速融化，解决除渣成本高效果不好的问题。
