DIN Standard Ceramic Ball Valves for PCI System is specially designed as per DIN and EN flange and face-to-face dimension standard.
, yang kemudian menyebar batubara dan pembakaran coke dan melelehkan bijih besi padat, melepaskan besi cair. Aspek yang paling luar biasa dari metode ini adalah memungkinkan batubara yang lebih murah untuk dikonsumsi dalam sistem, menggantikan kokas mahal, sehingga sangat mengurangi biaya. Karena lingkungan yang berat di dalam tungku, (
2000K), pengamatan visual bentuk dan ukuran raceway tidak mungkin, oleh karena itu sensor pengukur jarak jauh digunakan untuk menyelidiki reaksi kimia dan fisik di dalam tungku.Namun, kecepatan tinggi pbubuk batubara ulverized sangat abrasif, fitting pepe dan katup yang penting untuk dipakai. Terutama wajah penyegelan katup. kebocoran akan menyebabkan kegagalan besar sistem. Ketika keramik canggih digunakan untuk katup dalam sistem bubuk batu bara bubuk, keadaan menjadi jauh lebih baik.
Kekerasan murni99% alumina keramik dan keramik zirkonia kekuatan tinggi lebih dari HRA 88, jauh lebih keras dari bubuk batubara. Insinyur teknis dari FOYO memiliki banyak pengalaman dalam sistem PCI di pabrik baja, disign dan struktur FOYO

Background:
Pulverized coal injection (PCI) method was developed in the 19th century,
The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the mid-bottom inlet of a blast furnace, then mixed with secondary hot air (termed the "blast") supplied through a blowpipe in the tuyere and then piped to a furnace to create a balloon-like cavity called a "raceway", which then propagates coal and coke combustion and melts the solid iron ore, releasing molten iron. The most remarkable aspect of this method is that it allows for cheaper coal to be consumed in the system, replace expensive coke, thereby remarkably cutting down on costs. Because of the severe environment inside the furnace, (>2000K), visual observation of raceway shape and size is impossible, therefore remotely measuring sensors are used to investigate the chemical and physical reactions inside the furnace.
However, the high speed pulverized coal powder is very abrasive, pepe fittings and valves are essily to be worn. Especially the sealing face of the valves. leakage will cause big failure of the system. When advanced ceramics are used for valves in pulverized coal powder system, things were become much better.
The hardness of pure >99% alumina ceramics and high strength zirconia ceramics is more than HRA 88, much harder than coal powder. Technical engineers from FOYO have much experience in PCI system in steel plant, the disign and structure of FOYO ceramic ball valves are optimized and improved specially for PCI system.
On the other hand, Foyo has powerful technical team and can respond quickly to user requirements. we developed DIN/EN standard full lined ceramic ball valves for customers all over the world.
It has been proved that Foyo's full lined ceramic ball valves for PCI system have excellent stability and reliability, more than 5 times service life than commen metal seated ball valves, even longer, which reduce much maintenance time and cost.
Customerized flange and face-to-face dimension is optional.
