Pusher Type Slab Reheating Furnace Gas Fired

Pusher Type Slab Reheating Furnace Gas Fired – High-Efficiency Industrial Heating Solution for Steel Mills

JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD makes Pusher Type Slab Reheating Furnace Gas Fired systems. Steel mills keep them running day and night. Our plant sits on 20,000㎡. Fixed assets total 80 million yuan. More than 100 engineers and skilled workers form the team. Heating capacity goes up to 200 t/h. Working temperatures fall between 1150°C and 1250°C. Energy use comes in at about 1.1 GJ/t steel. Fuel bills drop. More tonnes roll off the line.

What Is Fired?

This industrial thermal processing equipment is intended to heat steel slabs to rolling temperatures of 1,100 °C to 1,300 °C for hot strip mills and heavy plate production plants. Your slabs are fed in one end and mechanically pushed through multi-zone heating chambers utilising hydraulic pusher devices.

The burners run on natural gas, blast boiler gas (BFG) or mixed gas. Each one sits where it does the most good. Heat passes freely between the preheating, heating and soaking zones. Slabs end up at an even temperature. Surface oxidation and scale loss stay under 1.5%.

Three headaches on the line get solved here. Bottlenecks in throughput clear up. Fuel burned per tonne goes down. Metallurgical quality holds steady. Water-cooled skid pipes move the slab along. They also protect the hearth from heat damage during 24/7 operation.

Core Advantages for Your Production Line

Lower Investment and Faster ROI

With our Pusher Type Slab Reheating Furnace Gas Fired, capital expenditure runs much lower than with a walking beam design. Build cycles are shorter too. Production downtime shrinks. Commissioning finishes sooner.

Simple Operation and Maintenance

A mechanical pusher has fewer moving parts than complex beam-lifting gear. Running it day to day takes less skill from your operators. Training and labour costs stay lower as a result. Output remains steady.

Flexible Fuel Options

A single multi-fuel burner setup lets you switch fuels when supply and prices change. Natural gas works. Coke oven gas and blast boiler gas work too. That kind of flexibility supports your energy buying strategy through market cycles.

Proven Thermal Efficiency

Dual-regenerative air-gas systems preheat the combustion air. They reach thermal efficiency of 45-60%. Recuperative combustion systems cut fuel use as well. They also give accurate temperature control in every heating zone.

Industrial Applications of Pusher Type Slab Reheating Furnace Gas Fired

Hot Strip Rolling Mills

Slabs heated to a common temperature reach your high-volume production lines in a steady flow. Constant mechanical pushing is no problem for the furnace. Surface quality stays intact, and the roughing stands still meet dimensional accuracy standards.

Production of Heavy Plate

For heavy gauge slabs up to 300mm, the enlarged soak zone ensures deep heat penetration. You obtain the required core temperatures without overheating the surface – crucial for subsequent rolling operations.

Speciality Alloy Manufacturing

In the production of high value steel grades rigorous control of the atmosphere is preventing alloy depletion at slab surfaces. It keeps the atmosphere decreasing or neutral and the material chemistry and mechanical qualities.

Quality Control Standards

We do full inspection methods before each furnace delivery. For the hydraulic pusher synchronisation, performance tests are carried out to avoid slabs becoming out of line. The integrity of the refractory is verified by ultrasonic testing and visual inspection for cracks or spalling.

Flow rates of skid pipe water cooling systems are pressure tested for leakage. Combustion efficiency is validated by flue gas analysis (O2 and CO levels) according to ISO 13577. The automation systems contrast the real thermocouple data with the mathematical heating models.

Your furnace, the Pusher Type Slab Reheating Furnace Gas Fired, leaves the factory only after it has passed national and industrial quality standards confirmed by our own quality inspection department.

FAQ

Q: What steps bring specific fuel consumption down?

A: Fit metallic recuperators that run at high efficiency. They preheat the combustion air to more than 500°C. Then add pulse firing controls. These set burner output from live slab temperature feedback.

Q: What prevents slab pile-ups during pushing?

A: Laser-based slab tracking systems monitor positioning throughout the heating cycle. Precision hydraulic pressure monitoring detects warping or misalignment, automatically adjusting pusher force to maintain smooth movement.

Q: How do you minimize skid marks on heated slabs?

A: Offset skid designs help shorten soaking zone residence times. That cuts contact area. Hot rider systems carry heat into shadow areas better. Surface temperatures end up more even.

Q: How long can the refractory lining last?

A: With proper upkeep, a solid monolithic lining can last 5-8 years. Thermal shock causes early wear. Controlled heat-up and cool-down cycles stop it.

Q: Can the furnace run on more than one fuel?

A: Yes. Dual-fuel burners give you a choice: natural gas or coke oven gas, and you can switch between them. What you use comes down to what your plant can get and what it costs. Should the energy supply turn shaky, you keep running.
