What is the use of tube furnace?

Tubular furnaces are mainly used in metallurgy, glass, heat treatment, lithium battery positive and negative materials, new energy, abrasive tools and other industries, equipment for measuring materials under constant temperature conditions. The furnace structure is simple, easy to operate, easy to control, and capable of continuous production.

Tubular atmosphere resistance furnace is mainly used in metallurgy, glass, heat treatment, lithium battery positive and negative materials, new energy, abrasive tools and other industries to measure materials under constant atmosphere conditions .

Tubular furnaces

Tube furnaces are all new types of high-performance and high-energy-saving electric furnaces developed with new technology, including single-tube, double-tube, horizontal, openable, vertical, single-temperature zone, dual-temperature zone, three-temperature zone, etc. Tube furnace type. It is mainly used for experiments and small batch production in universities, research institutes, industrial and mining enterprises, etc. It has simple operation, high temperature control accuracy, excellent heat preservation effect, large temperature range, high furnace temperature uniformity, multiple temperature zones, optional atmosphere, vacuum furnace type, etc.

You can choose a single set point or a 30-segment programmable controller. Energy-saving ceramic fiber material and double-layer structure can reduce the surface temperature to normal temperature. It has a long uniform temperature zone, easy operation, reliable sealing, high comprehensive performance index, and is at the domestic level. The furnace tube can be equipped with heat-resistant steel, quartz glass, ceramic tube and other materials.
Advantages:
mature technology;
simple furnace structure;
easy to operate, easy to control, and capable of continuous production;
high yield of ethylene and propylene, high product concentration;
power Low consumption and high thermal efficiency; most of the
cracked gas and flue gas can be recovered;
the scope of application of raw materials is gradually expanding with the progress of cracking technology;

Multiple furnaces can be combined for large-scale production.

Disadvantages:
(1) The applicability to heavy raw materials is limited to cracking heavy raw materials. Because heavy raw materials are prone to coking, it is necessary to shorten the operation cycle, reduce the cracking depth, and often light coke, which shortens the effective production time throughout the year. , It also affects the life of cracking furnace and furnace tube. As a result of reducing the cracking depth, the utilization rate of raw materials is not high, the quantity of low-value products such as heavy raw oil is large, and the cost of public works is also increased.

(2) According to the process requirements of high temperature, short residence time and low hydrocarbon partial pressure, the surface thermal strength of the furnace tube is bound to increase, which requires oil-resistant high-temperature alloy pipe and cast pipe technology.
