Gas annealing furnace manufacturer, well shaft quenching furnace

Description :

　　Gas annealing furnaces mainly use large trolley furnaces as annealing equipment, suitable for heating, tempering, annealing, normalizing, tempering of large welded parts, pressure vessels, rings, rollers, forgings, castings, pipe fittings, steel ingots, marine engines, military products, as well as heat treatment of various mechanical parts.

　　The structural form of the gas trolley furnace: It consists of a full fiber furnace body, full fiber furnace doors (lifting furnace door, sliding furnace door, double opening furnace door), furnace car, combustion system, smoke exhaust system, sealing system, automatic control system, upper industrial computer distributed control system and other main parts.

　　Steel frame: The steel frame is welded from steel sections, steel plates, etc., lightweight and reliable. The door post is connected to the furnace steel frame as a whole by splicing channel steel. The lower part of the furnace body is composed of specially made castings (sand sealing knives) of uniform specifications and steel plates, and the steel frame is equipped with platforms and escalators. All parts of the furnace that require inspection, maintenance, operation, and upkeep have platforms and safety escalators. There are multiple peepholes on both sides of the furnace body and the rear wall of the furnace body, as well as on the furnace door. The view of the peepholes covers all areas of the furnace, making it easy for operators to understand the situation inside the furnace. Considering the height issue in the workshop, the furnace door adopts a sliding structure. The furnace door has an electric transmission system that moves to the left or right.

　　Lining: In addition to the trolley, it adopts a fully refractory fiber structure with low thermal inertia, which can flexibly adjust the furnace temperature and meet the requirements of a large range of heating and cooling rates. The lining structure is a refractory fiber combination structure and a refractory fiber folding module. The temperature rise of the outer wall shall not exceed the ambient temperature+50 ℃.

　　Furnace car steel structure: The furnace car steel structure frame is composed of two longitudinal beams and several transverse beams spliced together, with thick steel plates on the surface to ensure rigidity and prevent deformation under full load conditions. Driven by two worm gear reducers, the structure is reliable and the service life is long.

　　Fire resistant insulation material: The trolley surface is a load-bearing fire-resistant layer, using specially made large block castables to form blocks, which not only ensures the pressure resistance strength of the furnace car, but also ensures the fire-resistant strength of the load-bearing surface. The bricks on the side of the car are made of irregularly shaped castables to form blocks.

　　Combustion system: The combustion system of this furnace adopts high-speed temperature control burner, which consists of high-speed burner, intelligent combustion controller, large/small gas valve, air dual position regulating valve, high-pressure igniter, and flame monitor.

　　Combustion supporting air supply: Each furnace adopts one centrifugal high-pressure blower, and the inlet of the blower is equipped with an electric regulating butterfly valve. The air preheater can preheat the air to around 300 ℃.

　　Natural gas: The gas intake in the workshop needs to be depressurized. Emergency shut-off valves, gas flow orifice plates, automatic detection of gas flow and pressure are installed on the main pipeline to ensure production safety. Parameters such as gas pressure and instantaneous/cumulative gas consumption are displayed and operable on the upper computer.

　　Smoke exhaust system: It is equipped with an upper row steel chimney, which is about 3m above the workshop roof. It adopts an upper mounted radiant heat exchanger. To improve the service life of the chimney and preheater and ensure their service life, the smoke exhaust system consists of a furnace pressure automatic control system and a waste heat recovery system.

　　Automatic control system: The fully automatic large-scale sliding furnace door trolley furnace automatic control system consists of temperature control system, combustion control system, pressure automatic control system, fault alarm system, and power control system. The temperature control method adopts a closed-loop self-control system composed of temperature control thermocouple, intelligent digital temperature control instrument (or computer system), and high-speed temperature control burner system, which automatically controls the temperature inside the furnace according to the requirements of the heat treatment process curve.
