Low-nitrogen recarburizer manufacturer nodular cast iron graphitized petcoke supply

Foshan Jitian Foundry Materials Co., Ltd., as a professional carbon refiner manufacturer, supplies continuously to Zhaoqing's foundry. There are three main types of Yoshida recarburizers, but they are all petroleum coke recarburizers. Carbon (sulphur 0.8%), semi-graphitized carbonizer (0.3% sulfur), full graphitization carbonizer (0.05), so it can basically meet the needs of major foundries. The specific recarburizer indicators are as follows. Customers in need can contact the latest recarburizer prices.

Ductile iron manhole cover, ductile iron sleeve, spheroidal tube, spheroidal tube, iron cast tube, iron cast pipe. In the production process of spheroidal pipe fittings and manhole cover castings have reached the domestic advanced level. The ductile iron pipe fittings strictly implement the national standard GB13295-2003 and the standard ISO2531 and EN545 standards, and the manhole cover implements the EN124 standard. Since its establishment, the company has consistently pursued / quality ** / the purpose of the mold workshop, machining workshop, hydraulic workshop, laboratory, sand cleaning workshop and other processing and testing equipment to improve the company's implementation / people-oriented / modern management system, focusing on improving employees The overall quality to ensure the professionalization of production, the high quality of the products.
 
Now our company has a large number of ductile iron pipes, which will be at the price, batch and zero, depending on the application, there are thick-walled pipes and thin-walled pipes. Seamless steel pipes are mainly used as oil geological drilling pipes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation. There are jointless steel pipes along the circumference of their cross-section. According to different production methods, it is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, and top pipe, etc., each with its own process regulations.

What is spheroidal graphite cast iron? Ductile iron is a kind of cast iron. Because the spheroidized spheroids precipitated in the metallographic structure are spheroidized into casting after the casting, the graphite is spherical and the mechanical strength is higher than that of gray cast iron. HT150, HT200, HT250, HT300, HT350, H, T are the initials of gray and iron, respectively, and the number indicates the lower limit of tensile strength in MP.) It is greatly improved, so it is called spheroidal cast iron composite manhole cover with high strength and low price. Beautiful appearance. Can be freely colored, installed, maintained...

Zhaoqing Wholesale DN1400 Ductile Iron Pipe Price The centrifugal spheroidal cast pipe is a cast iron pipe made by spheroidizing molten iron through a centrifugal casting process. The miracle of the spheroidization process occurs as follows: the molten iron is added with magnesium or a rare earth magnesium spheroidizing agent before casting, and then the flake graphite becomes spheroidal graphite. The problem with flake graphite is that it causes a "split" effect on the iron matrix. This leads to inevitable brittle cracking, while spheroidal graphite causes stress concentration due to flake graphite. Therefore, the splitting, the lightening, and the toughness of the iron matrix can be avoided. Therefore, the centrifugal ductile cast pipe has degree (three times the strength of the gray cast iron pipe), high elongation (the gray cast iron pipe elongation is zero, and the ductile iron pipe elongation is ≥10%), and corrosion resistance (30 times that of the steel pipe) ), excellent performance against earthquakes.

The ductile iron pipe adopts the "gong" brand cast iron raw material which is famous for the low content of S and P elements. It also affects the comfort and performance of the driving, and should also meet the requirements of the casting process. The product adopts the advanced and new circular production line process. The processing cost of the ductile iron is too low, it becomes weak acid, and the molecular structure of the ductile iron is excellent. The strength and impact load, some plastic cast iron manhole covers can be particularly effective in water seepage from the source, although you can take some precautions to protect employees, using a new manhole cover with ductile iron.
