Analiza i kontrola neujednačenosti proizvoda valjaonice debelog lima s aspekta reguliranja kvalitete

Nowadays, when the most important condition for the survival and development of a company is to satisfy the varying expectations of customers, quality starts to be an important element of the strategy of each firm, which wants to achieve the success. Presently, the Polish steel industry is on the stage of stagnation, so the improvement of the quality management system in the activity of metallurgical companies can be an important factor for making this situation better. However, it must be remembered that the elimination of non-conformances and their sources as early as in the manufacturing process is a very important step to obtaining „high” quality products. Within the study described in this article, an analysis of the non-conformances of products manufactured in the Plate Rolling Mill of one of the largest steelworks in Poland was carried out for the period from January, 1999 until March 2000.Danas, kad je za preživljavanje tvrtki najvažnije da zadovolje promjenljiva očekivanja kupaca, kakvoća postaje važan strateški element svake tvrtke koja želi biti uspješna. Trenutno Poljska industrija čelika stagnira. Stoga za promjenu takve situacije važnu ulogu može odigrati unapređivanje sustava regulacije kakvoće. Međutim, ne smije se zaboraviti da je uklanjanje neujednačenosti proizvoda još u tijeku proizvodnje vrlo važan korak prema postizanju “visoke” kakvoće proizvoda. U okviru studije opisane u ovom članku provedena je analiza neujednačenosti proizvoda u valjaonici debelog lima u jednoj od najvećih čeličana u Poljskoj i to za period od siječnja 1999. do ožujka 2000
