High temperature box-type heat treatment furnace

High temperature box-type heat treatment furnace the whole furnace body adopts double internal structure, air gap isolation in the middle, even if the temperature of the furnace chamber reaches the highest temperature, the surface of the furnace body can still be safely touched without hot feeling. The inner tank is made of alloy material, which can withstand high temperature and high pressure. Box-type furnace with high temperature and vacuum heat treatment furnace inlet flow meter and pressure gauge, furnace body is equipped with a pressure relief valve pressure exceeds a certain pressure relief automatically protection, the maximum temperature reached 1200 degrees, heating element is molybdenum alloy resistance wire, high temperature box type heat treatment furnace is mainly used in colleges and universities laboratory, industrial and mining enterprises, laboratories, for chemical analysis, physical testing and vacuum sintering atmosphere and dissolved metals, ceramics, etc, used in electronic components, powder metallurgy, magnetic materials, quartz material products such as glue, presintering and firing, other materials can also be used for heat treatment process, etc.

The current application of high temperature chamber heat treatment furnace is as follows:

1. Final heat treatment for common structural parts.

2. Improve the machinability of low carbon steel and low carbon alloy steel.

3. Pre-heat treatment of more important parts made of medium carbon structural steel.

4. Eliminate the apoplexy secondary cementite of hypereutectoid steel and prepare the tissue for spheroidizing annealing in a high temperature box-type heat treatment furnace at 1600℃.

5, for some large or more complex shape of parts, quenching may have the risk of cracking, normalizing is often replaced by quenching, tempering treatment, and as the final heat treatment of such parts. At this time, it can not be called normalizing, but air quenching. In order to increase the hardness of low carbon steel, the normalizing temperature can be increased appropriately.

Safe operation of high temperature box-type heat treatment furnace:

Improper operation of high temperature box heat treatment furnace, a variety of safety accidents are very easy to occur, such as electric shock, scald, burn and so on. Gas and controllable atmosphere are flammable and explosive gases, if not used properly, poisoning and explosion accidents will occur. Therefore, must strictly follow the various safety procedures to operate and use high temperature box-type heat treatment furnace, in order to prevent accidents of people and equipment. The safe operation of high temperature box-type heat treatment furnace includes the following contents:

1, oven operation: oven is to avoid high temperature box-type heat treatment furnace in the use of the process of masonry cracking and peeling phenomenon, to ensure the service life of one of the key measures, must be in accordance with the pre-determined oven process curve, in order to remove water in masonry, brick conversion complete.

2, open and stop furnace operation: proper operation, can completely ensure that no personal and equipment accidents, for this reason, must strictly follow the high temperature box-type heat treatment furnace operating rules, rational use of equipment, make good preparation before the furnace and stop furnace, so that the process operation step by step.

3, thermal regulation operation: in the operation process of the furnace, to closely observe the furnace fuel combustion or electricity utilization, timely adjust the heating, furnace temperature, furnace pressure and other thermal parameters, ensure the normal operation of the equipment.

4. Daily maintenance: maintenance and inspection of high-temperature box-type heat treatment furnace in order to keep it in good condition or maintain its working capacity during the use of the furnace, such as equipment spot inspection, regular inspection, equipment lubrication and maintenance, etc.
