Structural characteristics of trolley heat treatment furnace
The trolley is a heat treatment furnace. It is a national standard energy-saving periodic operating furnace. It has an ultra-energy-saving structure. It uses composite fiber insulation, ultra-lightweight and high-strength micro-bead vacuum ball energy-saving bricks. The mouth prevents workpieces from hitting the bricks, actively seals the trolley and the furnace door, and integrates rails. It can be used on a horizontal ground without the need for a foundation device. It is mainly used for high chromium, high manganese steel castings, gray iron castings, ductile iron castings, rolls, steel balls, crusher hammers, hardening, annealing, aging and heat treatment of various mechanical parts.
Features of trolley furnace:
1.The furnace door lift adopts an electric structure, with a button in front of the furnace, which is easy to operate.
2.The shell of the trolley furnace is welded by section steel and steel plate, and the appearance is beautiful and solid.
3.This car furnace is mainly used for heat treatment of metal parts such as normalizing, quenching and tempering, and tempering.
4. The lining material is made of aluminum silicate fiber structure, and the trolley is made of heavy and light bricks. Good heat preservation and energy saving.
5.The temperature control adopts the intelligent digital display appearance to control the furnace temperature, and the active recorder of Zhongyuan Diagram is used to actively record the furnace temperature and over-temperature alarm.
6.The temperature control adopts intelligent digital display appearance to control the furnace temperature, and the active recorder of the Zhongyuan Diagram is used to actively record the furnace temperature and over-temperature alarm.
7.The heating element is an OCr25AL5 resistance band structure, which is placed on the furnace door, both sides of the furnace, the back wall, and the trolley. It is heated on five sides to improve the uniformity of the furnace temperature.
8. The trolley furnace shell is welded by steel plate, the trolley lining is made of refractory insulation bricks, and the trolley is attached with a heat-resistant steel furnace plate, which has strong bearing capacity and the trolley drive uses an electric structure. The walking is stable.
Trolley steel structure: Double-layer fish-belly steel beams and steel plates are welded together. Its rigidity guarantees normal operation under full load bearing conditions and does not deform in long-term use. The maximum load capacity of the steel structure of the trolley is planned to be 30 tons, which ensures that the deformation is still within the planned scale even when the load is uneven. Lining body: use heavy high-aluminum refractory bricks, light-weight refractory bricks, thermal insulation bricks, etc. to form a composite lining. The lining is built with grooved channels for heating elements, and the easy-to-smash and load-bearing parts are heavy and high The masonry of aluminum refractory bricks enhances the strength of the furnace lining structure. Wheels: The walking wheels of the trolley are made of castings and processed. The drive shaft is made of 45# steel, and is quenched and tempered. Roller bearings are selected for transmission bearings to ensure load requirements.
Furnace bottom plate: heat-resistant cast steel parts are selected, and the long-term use temperature is ≤950℃ to ensure that it will not deform, oxidize, and crack during use. It can prevent the workpiece from falling off and falling into the groove of the heating element device on the trolley to form a short circuit and damage the heating element.
Trolley traction organization: The traction force of the trolley is a reducer. The reducer drives the sprocket to roll, and the sprocket connects to the gear on the trolley, and then drives the trolley to move. There are double insurance limit organization and chain organization for both entering and exiting the furnace.
Heating element: The trolley is equipped with a corrugated resistance tape as the heating element. The raw material is made of 0Cr25AL5 high-resistance alloy material. The power supply of the heating element is connected to the sliding contact line.
