Our company's SA283 Grade D mild steel hot rolled technique power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the SA283 Grade D mild steel hot rolled technique utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
In the process of SA283 Grade D mild steel hot rolled technique steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose SA283 Grade D mild steel hot rolled technique different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings. SA283 Grade D mild steel hot rolled technique Heat treatment services - such as annealing, normalizing, quenching, tempering, quenching and tempering, solution treatment, etc. We can also heat treat according to customer's SA283 Grade D mild steel hot rolled technique requirements.
BBN had provided SA283 Grade D mild steel hot rolled technique Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our SA283 Grade D mild steel hot rolled technique NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.
