Low and medium grade of cold rolled silicon steel roll were one of the main raw materials of small andmedium-sized motors. And the cost accounts almost about a third. In this reason, in order to control costs, some motor factories especially private production companies, procurement cold-rolled silicon steel coil
was only decided by the chairman or general manager, the purchasing agents just do some paper works. The policy makers keep their eyes on the purchasing price, quantity, transportationcosts, payment of funds, and it worked well.
Second, the quality of products was reached by the technical department engineers, then; they decided touse grades and the details. Require suppliers to provide warranty. First check the important parameters ofthe magnetic induction, iron loss and others, and never make the low grades instead of thehigh one.
Ensure the quality of products, to find from the low grade of good cold rolled silicon steelcoil what is perform better in magnetic induction, , metal loss.In purchasing, quality indicator optimal 800 instead of 600, with 600 standard of alternative qualityindex in 470 reached 470. If it arrive the standards after comparing test (including themachine test), we will amend the drawings. This way plays an important role in reducingthe cost (The different price is almost average of 200-300 yuan/ton in different grades).
Of course, such procurement will make themselves lots of troubles in choosing the bestsupplier from the mass, wasting a lot time. So some vendors may charge for some tochoosing fee and iron loss fee, of course, the major steel mills are not to do it.
Other side, you needn’t pay the interests for the new cold-rolled silicon steel roll,this will appeal to mid-range small machine production enterprises. They were the first men,they think the new internal quality guaranteed basically adding capacity, only on theplate type, especially with poor plate may have defects,but they are ordinary punch, step one foot, ran a piece, can adjust to the cut pieceby hand over with plate is poor, low prices, no discount can also authors efficiency..
