提高竞争力,在当今对产品质量比以往要求更严格的市场上保持领先地位,是所有的钢材生产商共同追求的主要目标。竞争力指的是卓越的产品质量、较高的生产能力和尽可能低的生产成本。冶金设备制造商的任务是为钢材生产商提供最先进的技术,其中包括先进的生产设备和先进的生产工艺,以使他们能够实现自己的目标。持续进行的各项研究和开发工作,使我们有可能在结构钢生产方面采用具有重大意义的各项创新技术。达涅利,作为引领长材产品生产设备发展潮流的国际知名公司,开发出具有创新意义、被称为PSP的先进的型钢定径轧制工艺。它已成为生产不仅能够满足最严格的尺寸精度要求、具有良好的表面质量的优质型钢产品,而且可以降低生产成本,最大限度地提高设备利用率,满足用户将来发展需要的有效手段。因此,采用PSP工艺的生产设备,在现在和未来几年内,都将代表着最先进的大中型型钢生产技术。本文将介绍达涅利先进的中型和大型型钢轧制工艺和设备。

BACKGROUND Intestinal ischemia has been described in case reports of patients with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)disease(coronavirus disease 19,COVID-19).AIM To define the clinical and histological,characteristics,as well as the outcome of ischemic gastrointestinal manifestations of SARS-CoV-2 *** A structured retrospective collection was promoted among three tertiary referral centres during the first wave of the pandemic in northern ***,radiological,endoscopic and histological data of patients hospitalized for COVID-19 between March 1st and May 30th were *** diagnosis was established by consecutive analysis of all abdominal computed tomography(CT)scans *** Among 2929 patients,21(0.7%)showed gastrointestinal ischemic manifestations either as presenting symptom or during *** CT showed bowel distention in 6 patients while signs of colitis/enteritis in *** patients presented thrombosis of main abdominal ***,when feasible,confirmed the diagnosis(6 patients).Surgical resection was necessary in 4/21 *** tissue examination showed distinctive features of endothelial inflammation in the small bowel and *** hospital stay was 9 d with a mortality rate of 39%.CONCLUSION Gastrointestinal ischemia represents a rare manifestation of COVID-19.A high index of suspicion should lead to investigate this complication by CT scan,in the attempt to reduce its high mortality *** shows atypical feature of ischemia with important endotheliitis,probably linked to thrombotic microangiopathies.
