Shaoguan City is located in the northern part of Guangdong Province. It is bordered by Guangzhou, Qingyuan, Huizhou and Heyuan in the south and west, and borders with Hunan and Jiangxi in the north. It is adjacent to Guangxi and is known as the “three provinces”. Shaoguan is a heavy industrial city in Guangdong with a strong industrial base. In the 1950s and 1960s and 1970s, the state successively built Shaoguan as a heavy industrial base in South China and a strategic rear in Guangdong, and established Shaoguan Iron and Steel Plant, Shaoguan Smelter, Shaoguan Excavator, Fankou Lead-Zinc Mine, Dabaoshan Mine, etc. A large number of key industrial enterprises have laid the foundation for Shaoguan industry in the local economy.
With the development of Shaoguan foundry industry, the demand for recarburizers has also increased. Foshan Jitian Foundry Materials Co., Ltd. has also supplied various refining agents to the foundry for a long time, mainly semi-graphitized recarburizers (0.3%). At the same time, Yoshida also supplies general calcined coke recarburizer (0.8% sulfur) and total graphitization recarburizer (0.05%).
The specific indicators for the semi-graphitized petroleum coke recarburizers to be supplied to Shaoguan are as follows:
Fixed carbon (FC) /% ≥ 98
Sulfur (SI) /% ≤0.3
Moisture (Mad) /% ≤0.5
Ash (A)/% ≤0.8
Volatile matter (V) /% ≤ 0.8
Nitrogen (N) /% ≤ 0.2
Particle size Remarks: 0-1mm 0-2mm 0-3mm 0.5-2mm 2-8mm 8-30mm (produced according to customer requirements)
If the customer has other requirements for particle size and indicators, please contact us! Yoshida recarburizer manufacturer
Shaoguan Cast Steel Co., Ltd. is a comprehensive private enterprise integrating casting and machining. The company is located in Lechang Industrial Park, Shaoguan, a major industrial production town in Guangdong Province. The factory covers an area of 75,000 square meters, including 36,000 modern factory buildings. The square meter, green area of about 20,000 square meters, beautiful environment, won the reputation of the green factory. The company's annual production capacity is more than 40,000 tons. The main products are used in mining equipment, metallurgy, building materials, electric power, shipbuilding, coal, chemical and machinery industries. The main materials are cast iron castings such as high manganese steel, high chromium cast iron, alloy steel, gray iron and carbon steel. The production capacity of single-cast steel is about 60 tons, and the production capacity of high-manganese steel is about 20 tons.
Since 2000, the steel industry has been in strong demand. At the same time, the production capacity has gradually increased. The downstream demand of the ductile iron pipe steel industry is closely related to real estate. However, the growth rate of the real estate industry has declined since the end of 2011, and the demand is not strong, which has brought pressure to the steel industry. More and more, in addition to the real estate industry chain, the automotive industry industry chain and investment industry industry chain demand growth has also slowed down, the future steel industry will face de-capacity.
There are many types of nodular cast iron, such as ductile iron manhole cover and ductile iron pipe. It is obtained by spheroidizing and inoculation to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially improves the plasticity and toughness, thus obtaining more than carbon steel. High strength. Therefore, its market application in ductile iron pipes is very extensive.
The spheroidal tube is the abbreviation of ductile iron tube. It has the essence of iron, the performance of steel, excellent anti-corrosion performance, good ductility and easy installation. It is mainly used for water supply, gas transmission and oil transportation in municipal and industrial and mining enterprises. The main raw material of the spheroidal tube is pig iron. The centrifugal ductile iron tube is made by adding a certain proportion of spheroidizing agents such as carbon, silicon, manganese, sulfur, phosphorus and magnesium to the pig iron and then conducting internal and external corrosion protection.
As the pillar industry in China, the automobile industry is developing vigorously. The key parts of the engine, such as the cylinder block, cylinder head, crankshaft, cylinder liner, piston, intake pipe and exhaust pipe, are almost all cast. Metallurgical, mining, power stations and other major critical equipment require high-quality major castings; in addition, the national economy's infrastructure and people's lives also require a large number of castings, and the water pipelines require high-tough ductile iron pipes of various sizes.
