Steel range material need to be heated: Q345 ； Q235 Steel billet dimension:120mm×120mm×6000mm Steel billet Max. Camber before charging into the furnace:≤4mm/M 1000mm Billet surface temperature before reheating: ≥850℃ Billet rolling temperature: 1050℃ ～ 1 100℃ Billet reheating capacity: 40t/h

Vertical Shaft Kilns. Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven ...

A simple model of the reheating furnace wall is shown in Fig. 1 [33, 36], and its typical application is the steel rolling reheating furnace in the steel industry.The high temperature gas in the inner of the hearth heats the billet steel at the one hand and emits heat to the furnace wall at the other hand.

Then a pusher furnace is a smart choice. Why? Because this type is designed specifically to operate in low-production-rate mills for common steel grades such as rebars. Highly adaptable . Top-fired pusher-type furnaces combine the benefits of sturdy construction and simplicity in design with low consumption rates. Common to both top and bottom ...

Specific fuel consumption in reheating furnaces may vary over a large range, depending on the material heated, type of furnace, fuel used, extent of waste-heat recovery, etc. Operating the furnaces at or near their design capacity reduces the fuel requirement per unit quantity of charge heated.

Walking beam furnaces are essentially state-of-the-art heating furnaces that are extremely efficient for processing large/heavy parts in semi-continuous mode. The handling system of this type of furnace (fixed beams and walking beams) can be made with hard refractory material, or with high temperature steel alloys in custom shapes according to ...

The John Cockerill reheating furnace standardises the thermal gradient of metal sheets, blooms and billets by optimising heat transfer on the surface of the steel, allowing for extreme temperature uniformity whilst preventing the formation of scale and the appearance of skid marks.
