Stainless steel tube annealing furnace

YiranStainless steel tube annealing furnaceThe equipment can eliminate the internal structural defects of stainless steel pipe materials, uniformly refine the structural composition, improve the plasticity and toughness of stainless steel pipes, and enhance the processing performance of stainless steel pipes. The stainless steel annealing furnace is mainly composed of an automatic feeding system, stainless steel tube conveyor, annealing heat treatment area, regenerative combustion system, stainless steel tube output system and other structures. It can be used for annealing treatment of workpieces such as stainless steel tubes with diameters greater than 15mm, seamless steel tubes, tube blanks, high-frequency welded steel tubes, etc. The Yiran stainless steel tube annealing furnace has the following advantages:

1. High annealing quality, low energy consumption for flue gas waste heat recovery, stable equipment quality, high degree of automation, simple operation and easy maintenance.

2. PLC digital intelligent control, visual design of regenerative combustion system, and highly integrated flue gas waste heat recovery system for stainless steel tube annealing heat treatment furnace;

3. Security measures, safe and reliable, low equipment failure rate, and simple maintenance;

4. Uniform furnace temperature, high stability, and high-quality annealing of stainless steel pipes.

5. The conveying system adopts independent frequency converter control, segmented control of operating speed, and can flexibly design speed difference output.

The brightness of the annealing heat treatment furnace for stainless steel pipes determines the quality of the product. The brightness of stainless steel pipes is influenced by the following factors:

1. Protect air pressure. Protecting air pressure is very important, mainly as a protective measure to prevent micro leaks. Generally speaking, hydrogen gas is usually used to protect air pressure. Stainless steel tube annealing furnaces should be kept away from moisture during operation. The furnace body of steel tube annealing furnaces must be kept dry, and there should be no moisture entering the steel tube during heating to destroy the atmosphere.

2. Annealing temperature. Stainless steel heat treatment generally adopts solid solution heat treatment;

3. Sealing performance: The stainless steel tube annealing furnace has good sealing performance. During inspection, soap water can be applied to the joints and seams of the annealing furnace to check for any gas leakage;

4. Annealing atmosphere: Pure hydrogen is generally used as the annealing atmosphere. If another part of the atmosphere is an inert gas, the purity can also be lower, but it cannot contain too much oxygen or water vapor.

5. Protect the gas pressure, in order to prevent micro leaks, maintain a certain positive pressure in the furnace to protect the gas pressure. If it is hydrogen, protect the gas;
