The Maintenance of Rolling Mill Equipment

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.

The temperature of billet in the rolling mill is 1200℃. The entry roller,  exit rollers and the lifting rollers of the TMT rebar steel rolling mill must be paid more attention, which requires each worker should know all kinds of safety common sense, the performance of rolling mill equipment, especially some workers of heating furnace, the furnace temperature is 800-1200℃. Combined with temperature meter and observation, to ensure the quality and negative pressure of billet. The fuel of heating is several kinds of materials, including anthracite, waste oil, natural gas and so on. Using the gas generator as a tool can reduce air pollution. The heating furnace must be equipped with pusher, and the ingot in the furnace must have 5-30 tons of raw materials.

In regard to the maintenance of rolling mill reheating furnace, the workers should carefully inspect the vulnerable parts such as furnace top, furnace wall and furnace door before opening the furnace normally. If cracks and spalling are found, the relevant departments should be contacted in time. The main measure to maintain the furnace body of the rolling mill is to prevent rapid cooling and heating. Therefore, it is necessary to operate strictly according to the heating curve or cooling curve. Whether the heating furnace equipment maintenance of rolling mill is timely or reasonable will directly affect the normal operation of the furnace and the service life of the furnace. Standardized and reasonable operation, timely and correct maintenance of rolling mill are prerequisites for energy saving and consumption reduction of furnace and prolongation of the service life of rolling mill.

The application of rolling mill equipment in the industrial production process has large thrust, low noise, and good energy-saving effect. Continuous casting and rolling should pay more attention to cultivating high-tech operators. The speed of the rolling mill is fast, the standard is high, and the output of the rolling mill equipment and the progress of the project are closely related to the upper screw-down device. Most of the small rolling mills are manually pressed, and the scales are mounted on the pressing screws. The rolling speed of the strip rolling mill is generally 8mm, and the bar and the rebar head are pressed at 40%. It is important for the maintenance of the burner to prevent the blockage of the gas tar. The blockage is generally caused by the high tar content of the coal stove. Therefore, after a period of use, the tar in the burner is checked by a professional. The condition of the rolling mill equipment requires the operating space around the heating furnace, as well as the surrounding walkways to ensure smooth, clean, non-stacking, and avoid running, rushing, dripping, leaking and so on.
