Pusher-Type Heating Furnace

Pusher-Type Heating Furnace for Industrial Steel Reheating | High-Efficiency Continuous Heating Solution

Steel reheating lines that never stop are what JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD builds Pusher-Type Heating Furnaces for. Up to 200 t/h runs through each furnace. Working heat sits in the 1150 to 1250 °C range. Energy use lands near 1.1 GJ per tonne of steel, a low figure for this industry. Fixed assets of 80 million yuan sit behind a 20,000㎡ production base. Over 100 technical staff work inside it. What you get is thermal processing equipment you can count on, built for hot rolling. Forging and tube production get the same cover. Dual regenerative combustion systems come with our pusher furnaces, and standard recuperative designs do too. Fuel choice is wide. Blast furnace gas works. So do natural gas and mixed gases.

Understanding Industrial Continuous Heating Technology

This is a thermal processing system that runs non stop. Metal charges get pushed through several heating zones by a mechanical or hydraulic pusher. Water cooled skid rails carry the charges along. Batch processing creates inefficiencies. Keeping the material in motion all the time is how this design sidesteps them.

Billets, slabs or blooms move through the preheating zone in a set order, pushed by a mechanism. The heating zone comes next, then the soaking zone. Temperature in each zone is held precisely, so the whole charge heats evenly. Compared with walking beam systems, the mechanical side is simpler. Maintenance needs drop too.

Less operational complexity benefits your production. The simple pusher movement demands less complex control systems and at the same time regular throughput rates are needed for subsequent rolling or forging processes.

Key Technical Specifications

Core Advantages for Your Operations

Lower Capital Investment: Buying a pusher furnace from us costs less than buying a walking beam system. Walking beam units are more complex to build, and the price shows it. Full production capability still comes with our design. You will not need an excessive capital outlay.

Shorter Construction Timeline: A simpler structural design makes installation quicker. Commissioning takes less time as well. Choose other furnace technologies and your plant starts running weeks later.

Straightforward Operation: Complex movement patterns are out. The mechanical pushing system makes no use of them. Very little training brings operators up to speed. Labor costs fall. Operational errors fall too.

Reduced Maintenance Demands: Fewer parts move, so service visits happen less often. Your crew spends less time on routine upkeep. More hours then go to work that earns money.

Fuel Flexibility: Combustion systems come in several choices, and they run on fuels your area can supply. Choose a fuel that is cheap and easy to get nearby. Energy bills stay under control that way.

Industrial Applications

Hot Rolling Mills: Billets get reheated without a break, so output holds steady and keeps pace with the fast rolling stands. Hold the temperature steady and each pass deforms the steel the same way.

Heavy Forging Operations: Big parts for cars or aircraft need soaking zones that are right on target. That is how internal stresses get removed. Our Pusher-Type Heating Furnaces hit the exact metallurgical phase change your alloy steels call for.

Seamless Pipe Production: Heating round billets for tube making works well even where there is a lot of dust. In tough conditions, the strong pusher mechanism holds up better than parts that move inside the furnace.

Quality Control Standards for Pusher-Type Heating Furnace

Temperature uniformity surveys check that the soaking zones are within tight tolerances of 5°C. Quality inspection department will check everything before shipping.

Thermal imaging shows the state of the refractory lining and spots hot patches. A precision laser levels the slide rails. The charge then will not jam or pile up while the furnace runs.

Flue gas readings tell you how well combustion is going. They keep the air-fuel ratio where it should be. Pressure tests on the hydraulic system of the Pusher-Type Heating Furnace hold pusher force and stroke performance steady. Your furnace structure then takes less mechanical shock.

FAQ

Q: How is oxidative scale loss kept low in your pusher furnace?

A: Advanced PLC-based air-fuel ratio control keeps furnace pressure a little positive. Cold air cannot get in. That stops oxidation from becoming excessive.

Q: Will the furnace take billets of different sizes?

A: Yes, adjustable pusher stroke settings and flexible skid rail configurations handle different billet lengths within your production mix.

Q: How often should we do maintenance?

A: Once a year, go through the whole unit. Check the water-cooled skids for wear. Also look at the refractory castable where it erodes close to the discharge areas. Every quarter, run routine checks on how the combustion system is performing.

Q: How are cold spots prevented at skid contact points?

A: Contact area stays small with staggered skid designs. Heat still moves to the billet undersides, so the temperature stays even across the whole piece.

Q: Once the unit is installed, what technical support comes with it?

A: Our engineering team helps with commissioning and trains your operators. They also stay available for technical advice for as long as the furnace runs.
