Our company promoted the alloy cost reduction work and achieved good results

 Shandong Chengshun Metal Material Co., LTD. whose special Rolling factory, manufacturing management department, equipment management department and other departments jointly optimize the control rolling and cooling process, continues to promote the alloy cost reduction work and achieves good results.

At the beginning of this year, the high second line of the special rolling mill completed the transformation of the coil screw dropping alloy project, and the bar third line also completed the process and equipment upgrading, which provides the equipment foundation for the production of low cost and high quality rod and wire products.

Third line years repair postpartum, the first time to carry out the three batch Φ 16 mm to 25 mm HRB400E rebar alloy technology experiment, the first experiment, chemical composition and controlled rolling technology can meet the performance requirements of cooling, subsequent mass experiment carried out for many times, optimize the composition of smelting and rolling technology constantly adjust, find the optimal production process model. At present, the cost of the alloy can be reduced by 6.4 yuan/ton after the upgrading of the rod three lines compared with before the upgrading. In May, vanadium reduction, rolling and cooling control process test of B500B rebar with size less than φ25mm was carried out in rod 1 and 2 lines and rod 3 lines, and the product performance met the requirements of internal control standards. Now it has carried out mass production in rod 1 line 2 line and rod 3 line, realizing the reduction of alloy cost of 68 yuan/ton.

After several rounds of preliminary process tests, the φ8-12mm specification vanadium-free process trial production and vanadium reduction process batch production have been completed. According to the preliminary test results and combined with the production organization requirements, the current batch production according to the vanadium reduction process, and the rolling speed of φ8-φ12mm is increased by 4m/s compared with that before the transformation, realizing the alloy cost reduction of 21 yuan/ton. In August, HRB400E with φ8mm and φ10mm specifications was carried out in the high line of manganese reduction process optimization test, the margin of each performance index is moderate, the follow-up will continue to promote the high line of HRB400E disk screw manganese reduction process trial production, and strive to fully realize the high line and high line of HRB400E disk screw manganese reduction process mass production, further reduce production costs. Enhance product market competitiveness.
