The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, RINA grade D stern frame steel steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and RINA grade D stern frame steel carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.
The company's main steel plates have twelve types of steel products like boilers and pressure vessels, low-alloy high-strength steel RINA grade D stern frame steel, wear-resistant steel plates, corrosion-resistant steel plates, high-rise building structural steel plates, marine structural steel plates, alloy structural steel plates, mold steel plates, carbon structural steel plates, shipbuilding and steel plates for oil production platforms, composite steel plates, steel plates for oil and gas pipelines. We offer various steel grades, and more than 300 kinds of thickness specifications.
Cold rolled coil products RINA grade D stern frame steel have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products RINA grade D stern frame steel is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils RINA grade D stern frame steel with different surface roughness can be produced (glossy surface or matte surface, etc.).
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized RINA grade D stern frame steel are higher than that of annealed RINA grade D stern frame steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of RINA grade D stern frame steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
As for Q460 series low alloy steel, there are three quality Grade C, D, E. RINA grade D stern frame steel, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
