The video show of a new horizontal annealing process line designed and constructed by guangdong strong metal technology Co.ltd.

Tunnel furnace is horizontally positioned. it is like a tunnel. this tunnel furnace is for bright annealing cold rolled stainless steel coil. it is coil to coil continuous operational. the annealing process takes place in protective gas to achieve bright and clean(BA) finishing of the coil surface. The tunnel furnace has another general name as bright annealing line. The bright annealing line is an essential unit for cold rolling mills of stainless steel flat coil. Strong Metal have over 30 years' experience in design and manufacturing tunnel furnaces for stainless steel industries. This video showcases a large tunnel furance built for a large cold rolling mill in China.

this post introduces the difference between 201 and 304 stainless steel. Strong Metal's heat treatment equipment are widely used in the stainless steel industry for annealing process of strip coil.

Stainless steels are generally heat-treated based on the stainless steel type and reasons for carrying out the treatment. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses.

Commonly used gear materials are various grades of high-quality carbon structural steel, alloy structural steel, cast steel, cast iron, and non-metallic materials. Generally use forging or rolled steel. When the size of the gear structure is large and the wheel blank is not easy to forge, cast steel can be used; for open low-speed transmission, gray cast iron or ductile iron can be used. Steels with better comprehensive performance should be selected; high-speed gears are prone to pitting on the tooth surface, and materials with high tooth surface hardness should be selected; gears subject to impact load should be selected from materials with good toughness. For high-speed, light-load and low-noise gear transmissions, non-metallic materials, such as cloth bakelite, nylon, etc. can also be used. Commonly used gear materials and their mechanical properties are listed in the table below.

[Outline description] Its most important core component is the furnace liner-a composite corrugated muffle tank. The high-temperature alloy furnace liner we use is 3~5 times longer than the ordinary 310 furnace liner, which greatly saves the cost of use. The ultra-wide 1600MM alloy furnace liner produced can support the annealing of high-end precision stainless steel strips to ensure product quality. Purchasing high-end alloy steel plates to ensure service life and indirect cost savings. Manager Liao also clearly pointed out that the current economic globalization is facing a countercurrent, and the epidemic has a wide-ranging and far-reaching impact. The traditional international economic cycle is significantly weakened or even blocked. Foreign purchases are more likely to be affected by the epidemic, unable to deliver on time, and vulnerable to force majeure. In this case, strengthening the domestic economic cycle will help strengthen the resilience of economic development. It will also help drive the international economic cycle and realize the mutual promotion of domestic and international cycles.

To cooperate with the epidemic prevention and control work to ensure the health and safety of exhibitors, visitors and staff of the exhibition, the "2021 China Heat Treatment Industry Plant Managers Conference and China Heat Treatment Industry Association 35th Anniversary Celebration Meeting originally scheduled to be held on November 3-7 ", "The 20th Beijing International Heat Treatment Exhibition" postponed, the specific time will be notified separately.

The first large-scale high-end application of stainless steel in the roof was the Chrysler Building in New York built in 1930. It was the world's tallest building at that time. The roof and wall panels were made of 302 stainless steel, which is still shining today.
