How to choose the material of the continuous feeding and discharging rotary tube furnace tube?

The selection of furnace tube materials for continuous feeding and discharging rotary tube furnaces is mainly based on factors such as operating temperature, medium environment, mechanical performance requirements, and cost. Here are some common furnace tube materials and their characteristics for your reference:

Stainless steel material:
Characteristics: It has good corrosion resistance and high mechanical strength, and can maintain stability in high temperature environments. In addition, stainless steel also has good processing performance, making it easy to produce pipes of different shapes and sizes.
Applicable scenarios: Suitable for occasions with certain requirements for mechanical performance and corrosion resistance, and the operating temperature does not exceed the maximum tolerance temperature of stainless steel.

Nickel based alloy material:
Characteristics: Nickel based alloy is a metal material with excellent high temperature resistance and oxidation resistance. At high temperatures, nickel based alloys can maintain high strength and toughness, making them particularly suitable for making pipes in high-temperature environments.
Applicable scenarios: Suitable for high temperature and high requirements for material strength and toughness.

Quartz material:
Characteristics: It has high purity, high temperature resistance, and good transparency. At high temperatures, quartz can maintain stable physical and chemical properties.
Applicable scenarios: Suitable for situations where high purity is required and the operating temperature does not exceed the maximum tolerance temperature of quartz.

Ceramic material:
Characteristics: It has excellent high temperature resistance and chemical stability. Compared with metal materials, ceramic tubes are less prone to oxidation and corrosion at high temperatures, thus extending the service life of tube furnaces. However, ceramic materials have high brittleness, and special attention should be paid to avoiding damage during the manufacturing process.
Applicable scenarios: Suitable for high temperature and high chemical stability requirements, but attention should be paid to avoiding mechanical shock and vibration.
When choosing furnace tube materials, you need to consider the following factors:

Temperature of use: Ensure that the maximum temperature tolerance of the selected material can meet the requirements of experiments or production.
Medium environment: Consider the gas or liquid medium that the furnace tube will come into contact with, and choose materials with good corrosion resistance.
Mechanical performance: Select materials with sufficient strength and toughness based on the mechanical loads that the furnace tube may withstand during use, such as pressure and vibration.
Cost: Consider the cost and availability of materials while meeting performance requirements.
