What is the steel plate cutting process?

Steel plate cutting can process and cut materials as required. When lifting the steel plate to the gas cutting platform during the cutting process, it is necessary to adjust the distance difference between the two ends of the steel plate and the guide rail (within 5 mm). According to the different ways of automatic and semi-automatic cutting, adjust the distance of each cutting gun, and determine the resistance and compensation of the cutting seam; when cutting thick plates again, the preheating flame should be larger, and the gas cutting airflow length should exceed 1/3 The thickness of the workpiece. When cutting workpieces of different sizes on the steel plate, you should cut small pieces first, and then cut large pieces. And obtain a satisfactory cutting effect.

The main application range of steel plate cutting includes ship plates, wear plates, ordinary carbon structural steel plates, high-quality carbon steel plates, low-alloy high-strength steel plates, alloy structural steel plates, boiler steel plates, pressure vessel steel plates, bridge steel plates, building structural steel plates, shipbuilding steel plates, Die steel plate, pipe steel plate and non-quenched and tempered wear-resistant plate. Because of its complete variety and reasonable price, it is very popular in the market and has a relatively high position in the market.

Cutting standard

1. Scope: This standard applies to the processing of raw material cutting and blanking. It is suitable for cutting and blanking processes using flame cutting and plasma cutting as cutting methods.2.Construction preparation:
2.1Material requirements:

2.1. 1 The steel plate used for cutting and blanking should be inspected and qualified by the quality department, and all indexes should meet the corresponding regulations of the national standard.

2.1. 2 The grade, thickness and surface quality of the steel plate should be checked before unloading. For example, the part of the steel plate whose surface corrosion depth exceeds the negative deviation of the national standard steel plate is not allowed to be used in the product. Without reducing the design thickness, a small area of ​​pitting can be polished by welding until it is qualified.

2.1. 3 Check the brand, specification and surface quality of the steel plate when unloading, and discharge the material after confirming that it is correct.

2.2 Construction equipment and tools:

2.2. 1. Cutting and blanking equipment mainly includes CNC flame cutting machine, CNC plasma cutting machine, linear cutting machine, semi-automatic cutting machine, etc.

2.2. 2 Before gas cutting, check that all equipment and tools of the entire gas cutting system are operating normally and can only be operated under safe conditions. In addition, they should be carefully maintained during the gas cutting process.

2.2. 3 Testing and marking tools are: steel ruler, tape measure, stone pen, marker pen, etc.

3.Cutting operation process:

3.1 During automatic cutting, when the steel plate is lifted to the gas cutting platform, the distance difference between the two ends of one steel plate and the guide rail should be adjusted to within 5 mm. When semi-automatic cutting, the guide rail should be placed on the plane of the steel plate to be cut, and then the cutting machine should be gently placed on the guide rail. The side of the cutting torch faces the operator, and the cutting nozzle is selected according to the thickness of the steel plate to adjust the cutting straightness and cutting speed.

3.2 According to different automatic cutting and semi-automatic cutting methods, adjust the distance of each cutting gun, determine the resistance, and consider the compensation of the cutting seam; in the cutting process, the inclination angle and direction of the cutting gun are mainly determined by the thickness of the steel plate.
