Vacuum Annealing Furnace Maintenance

When using a vacuum annealing furnace, sometimes the furnace will fail. At this time, many maintenance personnel will feel the cause of the failure is difficult to find, often a small fault to the entire furnace from top to bottom in and out of a comprehensive inspection , it will feel very time-consuming and laborious.

For those who have just been engaged in the maintenance of vacuum annealing furnaces, the overall understanding of the vacuum quenching furnace, the vacuum oil quenching furnace, and the vacuum heat treatment furnace is quickly established, and it is the most important to understand the relationship between the composition of the equipment and the various components. All the faults are resolved as if they were different from those experienced in the past, but after they are resolved, they can be summarized in several systems or several categories of equipment.

The purpose of vacuum annealing furnace maintenance is to restore the performance of the vacuum annealing furnace. Once the vacuum annealing furnace has completely or partially lost its use performance, the management personnel of the vacuum annealing furnace must determine the general cause of the failure based on the fault phenomenon, and then determine the scale of repair, and then organize the repair. But to be able to accurately determine the cause of the failure, it is required to understand the structure, working principle, function, maintenance requirements and maintenance status of the equipment.

Vacuum Annealing Furnace application in annealing of titanium alloys

Titanium has metallic luster and ductility. Density 4.5 g/cm3, Melting point 1660±10°C, Boiling point 3287°C. The main features of titanium are low density, high mechanical strength, and easy processing. The plasticity of titanium depends mainly on purity. The purer the titanium, the greater the plasticity. It has good corrosion resistance and is not affected by the atmosphere and seawater. At room temperature, it will not be corroded by dilute hydrochloric acid, dilute sulfuric acid, nitric acid or dilute alkali solution; only hydrofluoric acid, hot concentrated hydrochloric acid, concentrated sulfuric acid, etc. can borke it.

In recent years, rare metal pipes, especially titanium pipes, zirconium pipes, etc., have been widely used in aerospace, marine, nuclear power, petrochemical and other fields, and these industries have extremely high requirements on the quality of pipes.

Vacuum annealing is an important process for the production of intermediate and finished products. There are many ways to heat the annealing process, but annealing the titanium tube using vacuum annealing is a relatively new technology and process in the rare metal processing field.

The Vacuum Annealing Furnace frame is welded by various types of steel. The outer frame is made of channel steel as the main beam, the hoarding is made of cold thin plate, the channel steel is used as the main beam, and the bottom plate and front and rear end plates are made of midplane.

Transmission part: The trolley drive adopts motor and reducer to drive the front set of driving wheel drive through the chain. The door-to-door drive uses a combination of a worm gear reducer and a motor to electrically lift.
Sealing: The labyrinth structure is adopted for the seal between the trolley and the furnace body, and an automatic sand-sealing knife sealing device is arranged on the trolley side. The door seal adopts the roller type compression and the spring compression automatic mechanism to seal the furnace body. The furnace body part adopts the high quality refractory brick structure to ensure the sealing of the furnace. In the pressure part of the trolley, a high-alumina brick building is used, and the lower part is filled with thermal insulation bricks.
Combustion system: Several burning nozzles are installed on both sides of the oil furnace, and the heat flow circulates in the furnace to ensure the uniformity of the furnace temperature. Automatic and semi-automatic types can be selected as required.
Exhaust gas preheating device: A smoke exhaust preheating device is installed 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 for preheating by the fan, and then sent to the burning nozzle for combustion by the pipeline.
