The multi rod hot shear furnace is suitable for various fuels such as diesel, generator gas, natural gas, liquefied petroleum gas, and coal. Multiple aluminum rods are stored in the furnace at once, and the preheating time of the aluminum rods in the furnace is relatively long. This heating method has a certain homogenization effect on the aluminum rods. Since its launch on the market, it has been well loved by users and adopted by a large number of users. Traditional multi rod hot shear furnaces do not pay attention to the cutting of aluminum rods after cutting, which easily causes aluminum rods to pile up near the discharge switch, seriously affecting work efficiency and inconvenient for users to use. A new energy-saving multi support long rod fully automatic hot shear furnace is now proposed to solve the above problems. The characteristics of the long rod hot cutting furnace are mainly composed of a heating furnace body, a hot cutting machine, a feeding mechanism, a robotic arm, a combustion chamber, etc. In terms of electrical appliances, the Mitsubishi PLC programming control system and touch screen are mainly used, which is simple, convenient, and efficient to operate
