boiler parts

I have developed casting center tube structure with a distinctive way of material is used by our company independently developed by GM-9, GM-10, the HRC hardness of 30 or more materials, high strength, weldability, corrosion resistance, non - creep, do not crack, will not expand the use of deformed guaranteed service life 3 to 5 years. Due to high hardness, its wear resistance far superior to Cr25Ni20 material. Relatively superior heat resistance, heat-resistant temperature is higher than 1250 .
According to manufacturer requirements, can produce modular or monolithic center tube to reduce the number of castable damage, saving companies the cost of production.

At present, the center tube of the performance of our company is more extensive and the minimum fluidized bed furnace is 35 tons of the central cylinder, the largest fluidized bed furnace is 1025 tons the center of cylinder.


Combined central cylinder advantages: current central cylinder in the course of deformation of the upper part of easy damage, easy to wear and tear damage to the bottom, if the overall change is a waste of material added to the cost, but also more difficult to replace. Combined casting center is divided into upper and lower cylinder 2 ~ 3, the moment when you just need to replace the Ministry of damage to the lower part can be, so that not only saves materials has also reduced costs, while also saving time and maintenance costs of human-style.

. Products; heat: boiler burner burner, superheater comb line card, stable combustion body
                     Heart tube, hood, etc.
                     Wear resistant: pulverized coal pipe, ash management, import and export of coal mill hopper, lining
                      Anti-wear panels.
3. Applications: boiler burner, burner, fluidized bed boiler hood, the center tube, machine
                    Armed, mining, metallurgy, chemical industry, military, transportation, cement production equipment, etc.

Center for the current circulating fluidized bed boiler tube in general in two ways: First, by using Cr25Ni20 stainless steel pl
