Process design system feaures:
The system adopts the heating system of a continuous heating furnace, the bottom of the furnace is generally vaporized and cooled, and the steel is pushed out of the furnace side or the furnace is pushed out of the furnace. The air is preheated by a preheater. The fuel is producer gas, city gas, natural gas, etc. The system is divided into six parts: heating furnace, fuel furnace system, air supply coefficient, smoke exhaust system, temperature control and automation system, and vaporization cooling cycle system. It forms an organic whole, suitable for the production and processing of various specifications, billets and slabs.
The main technical parameters and performance:
1. Heating furnace name: push-steel continuous heating furnace
2. Fuel types: blast furnace gas, mixed gas, producer gas, natural gas, etc.
3. Heating steel type: structural steel, low and gold steel
4. Blank size: standard blank, 150mm(160)×150mm(160)×12000mml(6000)
5. Steel tapping method: end in and out, or hanging roller tapping, pushing in by pressing and pushing steel machine.
6. Combustion method: double heat storage of air and gas, single heat storage of air, and conventional combustion air heat exchange type.
7. Heating capacity: <200t/h. Adding ship temperature: 1150-1250℃
8. Cooling method of furnace bottom water pipe: vaporization cooling or water cooling.
9. Comparable unit consumption: 1.1GJ/t steel
