What is the furnace shell of the low temperature bright annealing furnace

        The furnace shell of the low-temperature bright annealing furnace is welded by steel plate and section steel, and the bottom of the furnace body is connected with a trolley light rail. The user does not need to install the foundation, just put it on the flat concrete floor. The lining material of the bright annealing furnace adopts ultra-light 0.6g/cm3 energy-saving refractory insulation brick, and the interlayer adopts aluminum silicate fiber cotton for insulation. Expanded insulating powder is filled between the furnace shell and the silicon-aluminum brazing interlayer of the furnace lining. The furnace mouth is made of heavy-duty anti-collision bricks and heavy-duty high-aluminum pressure-resistant bricks on the surface of the trolley.

        Thus, the drive screw is vertically reciprocated relative to the steel pipe (key 1), and the well applies a downward force on the steel pipe through the pull ring (key 1) connected to the head of the screw. The rollers (component 3) at both ends of the workbench exert a pair of upward supporting reaction forces on the steel pipe. Under the combined action of these three forces, the steel pipe in the simply supported beam state is compressed straight. When the pull ring moves to a fixed position, the impact iron on the pull ring causes the travel switch on the workbench to act, cutting off the power of the motor. Reinforced scaffold steel pipe straightening and rust removing machine makes full use of advanced technology, and a multi-functional building scaffold steel pipe straightening machine has been carefully developed. A new type of construction machinery and equipment with straightening, ash removal, rust removal, painting, diameter reduction and other functions. The product adopts three-dimensional triangulation and 14-wheel rotating hyperbolic rolling technology, which is stable and reliable. The self-stretching and straightening system of 14-round rotary cross-rolling is highly efficient and energy-saving (up to 18 meters per minute output), no damage to the steel pipe and no elongation.

        All resistance band elbows are fixed on the furnace lining with corundum ceramic high temperature nails. The wiring is led out by the same material lead rod. Absolutely guarantee long-term conduction without oxidation and disconnection. OCr27A/7Mo2 high temperature alloy resistance strips are distributed on five sides in the furnace of the quenching furnace. The bottom plate of the bright annealing furnace should be made of ZG35Cr24Ni7siN or ZG40Cr25N:20 high temperature heat-resistant steel. Use high temperature resistant and strong screws to fix in the refractory masonry of the upper furnace bottom. The joints between the blocks are stacked together to ensure that scale does not fall into the grooves of the heating element.
