I. Brief introduction of box furnace:
The box furnace belongs to the industrial cycle operation type industrial furnace. The outer shell is welded by steel plates and sections. The furnace lining is built with ultra-lightweight energy-saving refractory bricks. It is combined with high-purity aluminum silicate fiber cotton for insulation. , Placed on the two walls of the hearth and the bricks on the bottom of the furnace. Box furnaces are generally provided with thermocouple holes on the top. When in use, thermocouples are inserted into the furnace. The temperature and over-temperature protection of the box furnace are controlled by a temperature control system.
Second, the use of box furnace:
This series 950/1200 ℃ box-type resistance furnace is a periodic operation type electric furnace. Mainly for alloy steel products, various molds for normalizing, quenching, annealing, tempering and other heat treatment, or diamond saw blades for high temperature sintering applications.
Classification of Box Furnace:
1. Box furnaces have different internal structures and materials according to different operating temperatures. They can be divided into: medium temperature box furnaces with an operating temperature of 950 ° C, and high temperature box furnaces with an operating temperature of 1200 ° C and 1350 ° C. Ultra-high temperature box furnaces at 1600 ° C and 1700 ° C.
2. Box furnaces also have different heating methods: box resistance furnaces, fuel tank furnaces, and gas box furnaces.
3. The box furnace can also be divided into different uses such as quenching, annealing, tempering, baking, forging, etc.
