Design of Large-scale Girder Rolling Steel Workshop
Abstract
This article is mainly about the design of large-scale girder rolling steel workshop, including six aspects: production scope and characteristics, basic parameters, process flow, key equipment selection, auxiliary system configuration, environmental protection and safety requirements. Through the description of these aspects, we can get a basic understanding of the design of large-scale girder rolling steel workshops.
1. Production Scope and Characteristics
Large-scale girder rolling steel workshops mainly produce various kinds of girders, with size range from 900mm to 1500mm. The main production processes of large-scale girder rolling steel workshops include billet heating, membrane rolling, pre-rolling, finish rolling, gantry rolling and groove rolling. The workshop should strive for high technology, high efficiency, high precision, high quality and low cost.
2. Basic Parameters
The basic parameters of the large-scale girder rolling steel workshop include the total area, the length and width of the workshop, the height of the workshop, the clear height of the workshop, the number of rolling lines, the number of rolling stands, the types of machinery and equipment, the heating furnace types and specifications, the rolling speed and lines speed and the power of the main motor.
3. Process Flow
The process flow of the large-scale girder rolling steel workshop is as follows: the billet heating process, the pre-rolling process, the membrane rolling process, the finish rolling process, the gantry rolling process, and the groove rolling process. In each process, the main technological indexes include material heating temperature, rolling passes, rolling speed and rolling line speed.
4. Key Equipment Selection
The key equipment for the large-scale girder rolling steel workshop includes the billet heating furnace, the pre-rolling mill, the membrane rolling mill, the finish rolling mill, the gantry rolling mill, the groove rolling mill, the cooling bed, the temperature measurement device and other auxiliary equipment.
5. Auxiliary System Configuration
The auxiliary system of the large-scale girder rolling steel workshop includes the cooling water system, the steam system, the compressed air system, the lube oil supply system, the electric control system, the steel bar circulating system, the lifting transport system, the hydraulics system, the material conveying system, the waste gas treatment system, the lubricant circulation system and other special systems.
6. Environmental protection and Safety Requirements
In order to ensure the safety and efficiency of the operation of the large-scale girder rolling steel workshop, the workshop should be equipped with fire extinguishing system, water mist fire extinguishing system, electric control system, fire and explosion-proof electric control system, grounding protection system and lightening protection system. The workshop should also meet the requirements of environmental protection, such as reducing noise pollution, preventing dust pollution, controlling hazardous waste treatment and controlling production waste water.
Conclusion
The design of large-scale girder rolling steel workshop should be based on the production scope and characteristics, basic parameters, process flow, key equipment selection, auxiliary system configuration, environmental protection and safety requirements of the workshop. Through this article, the reader can have a comprehensive understanding of the design of large-scale girder rolling steel workshop.
