The vibration fault and its causes of the steel rolling equipment rotor show that the rotor is always in operation during the construction of rolling machinery, and the vibration fault is very common. There are three main reasons for the vibration fault. First, the rotor speed should be kept at a high state to meet […]

Recent years, regenerative combustion technology has been widely used in heating equipment. Compared with the heating furnace without waste heat recovery, regenerative heating furnace can save more than 40% energy. However, the investment cost is high, and there is the concept of saving energy without money saving. Recently, double regeneration (preheating gas and air 1000℃) technology is recommended for heating furnace to use surplus blast furnace gas. The efficiency is higher than 70%, and the energy saving is obvious.

Generally, there are strict rules and regulations in the production process of rolling mill workshop, because there is a certain risk in operating rolling machinery and equipment. Since the development of rolling mill, many industrial products on the market have been produced directly or indirectly by rolling mill. The development of rolling mill in the future is to eliminate a large number of labor costs in the production of rolling mill. Rolling mill is the most critical equipment for iron and steel enterprises. Rolling mill promotes the development of many industries.

Full continuous, no twist, high speed rolling. The roughing rolling mill and intermediate rolling mill are alternately arranged, and the pre-finishing rolling mill is installed in front of finishing mill. The maximum finishing rolling speed is 120m/s. The latest rolling speed guaranteed by the production practice will be proposed according to the different specifications of the wire rod, such as Siemens in 2010. The company has designed and manufactured high-speed wire rod mills for Xuanhua Iron and Steel Co., Ltd., and its final rolling speed guarantee value: small 5.5-7.5mm, wire rod 112m/s, medium φ5mm wire rod l 105m/s, The small φ6mm hardened rebar is 85m/s.
