Gas annealing furnace
The gas annealing furnace adopts labyrinth sealing structure and automatic sand-seal device to ensure the sealing between the furnace body and the trolley. The sealing of the furnace door adopts raceway type pressing and spring pressing mechanism. The furnace body is made of high quality firebrick to ensure the sealing of the furnace. The high-pressure part of the trolley is constructed with high aluminum bricks, and the lower part is insulated with thermal insulation bricks.
The combustion system of the gas annealing furnace is equipped with multiple nozzles on both sides of the furnace, so that the heat flow is circulated in the furnace to ensure the uniformity of the furnace temperature. Automatic or semi-automatic models can be selected as required.
The gas annealing furnace is equipped with a smoke exhaust preheating device, which is located at the upper end of the furnace. When the flue gas in the furnace passes through the preheater, it is sent to the cold air by the fan for preheating, and then sent to the burner through the pipeline for combustion assistance. A manual disc valve is installed at the outlet to adjust the pressure in the furnace.
Structural characteristics of gas type car furnace
1, gas type car furnace to gas as heat source, through the specific gas burner for combustion heating.
2. The steel structure of the furnace body is welded, and the shell sealing plate is made of special steel plate.
3. The trolley frame is composed of various large I-beams, channel steel, Angle steel and thick steel plates.
4, the car drive structure is compact, strong, flexible operation, easy maintenance.
5, the furnace door is made of high aluminum fiber refractory silk blanket, lifted by electric hoist, and equipped with the furnace door sealing and locking mechanism.
6, the chimney is equipped with automatic furnace pressure control valve, can adjust the cooling speed.
7, heating using high-speed burner, distributed on both sides of the furnace body, by the solenoid valve and proportional regulation of combustion.
8. The control system mainly regulates and controls the gas pipeline flow, flue gas flow and diluted air volume of each furnace by detecting the temperature and pressure of the natural gas truck furnace. In addition, a natural gas main quick cut-off device is provided. The temperature of the furnace is controlled by the zone, and each zone is equipped with a thermocouple to measure the temperature and enter the multi-point recorder to track and record the temperature in the furnace.
