Fast single log aluminium billet rapid heating furnace with hrizontal hot shear

Single log aluminium billet heating furnace with hot shear is used in the preceding process of aluminum extrusion,mainly for billet heating. It combines the new technology of gas spray burning and enhanced heating, hydraulic hot shearing, etc. This furnace has the advantages of flexible production, high automation, good operation circumstance and low energy consumption. So the hot log shear furnace is widely adopted by many manufacturers in a short time.

Single log aluminium billet rapid heating furnace with hrizontal hot shear for front loading press

Billet storage table and loading table

Single log aluminium billet heating furnace Billet storage table – Aluminum billet center and the longitudinal centerline of the furnace is parallel. The storage table is a gravity-type hydraulic cylinder used for loading and unloading long billets. Its welded structure is stable support frame and can withstand heavy weight.

Single log aluminium billet heating furnace Billet loading table – It is used to receive aluminum billet one by one from the storage table and deliver it into the furnace to ensure the continuity of production. As long as the billet is sent to the feeding table, the delivering process will start automatically.

Single log aluminium billet heating furnace Transmission inside furnace – Billet moves on stainless steel rollers mounted on a stainless steel stand, whose thermal expansion has been fully considered in the design.

Single log aluminium billet heating furnace Hot spray heating furnace

The hot spray preheating section of the heating furnace consists of a countercurrent heating system, which is professionally designed. It achieves efficient preheating by high-speed impacting in furnace cavity that has pressure control.

Single log aluminium billet heating furnace Combustion air preheating system
The system can preheat combustion air to 200-300℃ and reduce the exhaust smoke temperature to lower than 150 ℃. It can also speed up the heating rate and reduce gas consumption by 10%, thus achieves remarkable energy saving effect.

Single log aluminium billet heating furnace Temperature uniformity control
Automatic PLC temperature control program, the temperature uniformity can reach ±9℃.To accurately measure the temperature of every section of the billet, we adopt Japan,SMC integrated sliding cylinder drive thermocouple probe. The temperature measurement results are displayed on the human-computer interface.

Furnace chamber with pressure at the furnace mouth, which is good for thermalbefficiency and control, forms an air barrier that can separate the preheated spraying hot air and cold air. Thus can not only reduce heat loss and waste of energy but also can ensure the spray temperature.

Single log aluminium billet heating furnace Equipment reliability
The transmission roller components of furnace body (roller, roller sleeve, roller shelf)are made with special stainless casting steel, whose normal average service time are more than 3 years. The design of the gas pipeline has pressure regulating and monitoring, flame surveillance, automatic blow and sweep, etc, all the valves and control devices can ensure the safety factor of design has been reached.

Horizontal hot shear

It is made from machined steel plate, bolted and welded together to form a house for the fixed clamping shear rings, and guide rail for the moving shear unit. The frame is bolted to a fabricated steel base plate, fixed directly to the floor with foot bolts.

The moving shear unit has bronze liners bolted on and is connected to the shear cylinder by a floating block, minimizing non-axial loading on the shear cylinder rod

Shear ring

The shear rings are made from tool steel, grade H13 and hardened with tenacity.

precise measurement system)

The new design will make sure the billet length control in ±3mm, we Adopt mechanical scale,accurate and durable,not affected by any other factors.
