INTRODUCTION
Shandong Laigang H-shaped steel is a high-end steel product widely used in construction. It is one of the main supporting materials for buildings, bridges, towers and other steel structures. The production process of H-shaped steel is characterized by high precision in rolling and dimension control, advanced process and energy-saving control, and strict quality control. Therefore, it is very important to choose appropriate production process and equipment.
This paper discusses the production process of Shandong Laigang H-shaped steel, the choice of rolling process and manufacturing equipment, and summarizes the advanced production process and energy-saving control of Shandong Laigang H-shaped steel.
THE PRODUCTION PROCESS OF SHANDING LAIGANG H-SHAPEDSTEEL
1. Raw material inspection: raw steel is inspected for quality.
2. Heating: heating steel billet with a furnace at a certain temperature to reduce brittleness and improve plasticity.
3. Forming: cold rolling steel billet with a rolling mill to form steel with a certain shape and size.
4. Straightening: straightening the formed steel by a straightening machine.
5. Dimension control: using a gage to measure the dimension of the steel, and adjusting its shape and size to ensure the accuracy of the product.
6. Cutting: cutting the formed h-shaped steel according to the specified length.
7. Final inspection: inspect the final product to ensure its quality.
CHOICE OF ROLLING PROCESS AND MANUFACTURING EQUIPMENT
1. Rolling process: Shandong Laigang H-shaped steel generally uses three-beam four-driving four-roller mill, which is composed of two-high universal rolling mill and three-roller rolling machine.
2. Furnace: according to the demanadas of the production-mandatod end product, the characteristics of the raw material, the heating of Shandong Laigang H-shaped steel generally uses furnace and walking beam furnace.
3. Rolling mill: Choose the appropriate rolling mill to meet the requirements of forming and dimension accuracy.
4. Straightening machine: select straightening machine with stable performance, accurate straightening size and low failure rate.
5. Gage: it can be used to measure the dimensional accuracy of Shandong Laigang H-shaped steel, so as to make accurate adjustments to the actual size.
ADVANCED PRODUCTION PROCESS AND ENERGY-SAVING CONTROL OF SHANDING LAIGANG H-SHAPEDSTEEL
1. Advanced process control: Shandong Laigang H-shaped steel adopts advanced rolling process with automatic control and PLC programmable control.
2. Intelligent analysis and monitoring of production process: through the intelligent analysis and monitoring of the production process, the production efficiency of the product can be improved.
3. Waste heat recovery: through the recovery of waste heat, the consumption of thermal energy is reduced and the cost is reduced.
4. Optimized design of equipment: improve the design of equipment in a scientific and reasonable way, and reduce the energy consumption of the equipment in production.
5. Computer control: use computer to control the whole production process, reduce human interference, and reduce the occurrence of equipment failure and product defects.
SUMMARY
Shandong Laigang H-shaped steel is a high-end steel product with great application value in construction. In order to ensure the quality of the product and reduce the cost of production, we must choose advanced production process and appropriate equipment. This paper has discussed the production process, the choice of rolling process and manufacturing equipment, and the advanced production process and energy-saving control of Shandong Laigang H-shaped steel.
