Continuous casting of ultra low carbon stainless steel welding

Dalian Jinniu ultra low carbon welding stainless steel continuous casting project, through the efforts of relevant technical personnel to achieve a phased success, 1 months ahead of schedule to complete the task node. As of the end of 5, the number of special ultra low carbon stainless steel continuous casting furnace for 3 consecutive months to reach more than 80%, the successful implementation of the continuous casting of the furnace, reducing the cost of more than 40 yuan.

The stainless steel used for ultra low carbon welding is mainly used as the main line of the welding wire, submerged arc welding wire, argon arc welding wire and arc welding wire. At present, the domestic market demand for its main dependence on imports, the development of ultra low carbon steel with stainless steel welding can reduce user costs, huge market prospects. Because of the ultra low carbon welding of stainless steel with low carbon content (C = 0.026%), some steel grades have special requirements on the content of Si, our company has been casting production. Die casting production increases the cost of forging, the yield is also low, affecting the development of the market, is the biggest bottleneck restricting the production cost for a long time. By using the continuous casting process, the cost of per ton steel can be reduced by more than 1000 yuan, and the production cycle can be shortened and the production efficiency can be improved.

To maximize the benefits, at the same time for the mass production of the continuous casting process of the welding of stainless steel, fully realize the continuous casting production to replace the mold, the company group in February this year, which will be included in the 2008 one of the key research projects. And from the provisions of project implementation, to complete the project promotion is divided into two nodes: the first node completion time before June 30th, to reach the target for the completion of production test, the 3 consecutive month, the welding of ultra low carbon stainless steel continuous casting furnace number accounted for 80%, and no significant disagreements because of continuous casting quality. The second node completion time for the December 31st, more than 3 months to achieve ultra low carbon welding of stainless steel continuous casting, continuous casting and not because of significant quality disagreements.

At present, the process of continuous casting and continuous casting of ultra low carbon stainless steel can be accepted. Next, the project team will strive for ultra low carbon stainless steel welding to achieve full continuous casting.
