vertical vacuum tube furnace advantages

1. Overview of vertical vacuum tube furnace

The tubular furnace is a new type of electric furnace with high performance and energy saving developed by international advanced technology, including single-tube, double-tube, horizontal, open-type, vertical, single-temperature zone, double-temperature zone and three-temperature zone. Mainly used in colleges and universities, scientific research institutes, industrial and mining enterprises and other experimental and small batch production. Safe and reliable, simple operation, high temperature control accuracy, good heat preservation effect, large temperature range, high uniformity of furnace temperature, temperature area, optional atmosphere, vacuum furnace type, etc.

Single set point or 30 - segment PROGRAMMABLE controller is optional. Energy - saving ceramic fiber material and double - layer structure can reduce the external temperature to normal temperature. Long temperature zone, easy to operate, reliable sealing, high comprehensive performance index, in the domestic level. Furnace tube can be equipped with heat resistant steel, quartz glass, ceramic tube and other materials.

Vacuum tube furnaces are of periodic operation type. For laboratory, industrial and mining enterprises, scientific research units for element analysis and determination and general small steel pieces quenching, annealing, tempering and electronic ceramics and other new materials.

The complete supply range of vacuum tube furnace equipment includes temperature controller, thermocouple, compensation conductor, etc. There are two kinds of temperature control: relay control and thyristor control. Due to the intermittent operation furnace, 40 sections of PlD programmable control is generally adopted to strictly control the firing process of products.

According to the type of furnace tube furnace is divided into: vertical furnace, cylinder furnace, large square furnace;

It is divided into chemical reaction furnace, liquid heating furnace, gas heating furnace and mixed phase flow heating furnace.

2. Classification of vertical vacuum tube furnace:

1, vacuum tube furnace, atmosphere tube furnace.

2, ordinary tube furnace, rotary tube furnace, multi-station tube furnace.

3. Separate tubular furnace, integrated tubular furnace, vertical tubular furnace and horizontal tubular furnace.

4, single temperature zone tube furnace, double temperature zone tube furnace, three temperature zone (multi temperature zone) tube furnace.

3. Advantages of vertical vacuum tube furnace:

Mature process;

Simple furnace structure;

Easy operation, easy control, continuous production;

The yield of ethylene and propylene is high and the product concentration is high.

Low power consumption and high thermal efficiency;

Most of the pyrolysis gas and flue gas can be managed for recovery;

With the progress of cracking technology, the application scope of raw materials is expanding.

Can be multi - furnace combination and large - scale production.

Disadvantages of vertical vacuum tube furnace:

(1) The applicability of heavy raw materials has certain limits

When cracking heavy feedstock, it has to shorten the operation cycle, reduce the cracking depth, often light coke, shorten the perennial effective production time, and also affect the life of cracking furnace and furnace tube. As a result of reducing cracking depth, the utilization rate of raw materials is not high, the quantity of low value products such as heavy raw materials oil is large, and the cost of public utilities also increases.

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

4. Tubular furnace product features

Optional import single set point or 40 - segment PROGRAMMABLE controller.

Safety features include adjustable overtemperature protection and safety lock system for door opening and cutting heating.

Energy-saving ceramic fiber material and double shell structure, with high speed of rising and cooling, low energy consumption. The outer temperature can be reduced to normal temperature and the inner cavity temperature can be evenly distributed.

High quality heating element, long service life.

Optional: With exhaust port and inert gas inlet.

40 section PROGRAMMABLE controller model can choose RS-485 serial port, to achieve computer communication.
