论文主要内容包括:原料的选择、生产工艺的制定、典型产品工艺计算、主要设备和辅助设备的选择,并且对主要设备(轧辊和电机)的能力进行了校核,对车间主要经济指标、生产车间布置和环境保护,进行了设计和规划。
ABSTRACT
Strip is one of steel and iron product. It plays an important role in the industry, agriculture, transportation and construction. The demand on the small section is very enormous in our country national economy development. In recent years, many new technologies and equipments, such as continuous casting-rolling, are developed to produce the small size in cross-section alloy steel shape in the various countries.
The design is a manufacturing workshop of hot rolling plate with a output of 3000 thousand product specifications range from (~)×(700~1600)mm, used steels of carbon steel、alloyed steel、stainless steel(25%)。
The paper mainly includes the selection of raw material and subsidiary facilities and main facilities, formulation of produce technology, technology calculation of the typical production, proofreading the capacity of main fatuities (including rollers and the electrical machinery). Setting about the products design it plans exactly the main economy norm of the workshop and its arrangement , environment protection and so on .
