Continuous casting and rolling mill process improvement

According to the different rolling process, continuous casting rolling mill is famous for its high configuration efficiency and low energy consumption.  

1. The molten steel temperature is determined according to the lifting distance and the temperature in the workshop after the scrap steel is smelted and transferred through the molten steel ladle.  Avoid the steel water temperature falling too fast, which will lead to the phenomenon of stacking and sticking when pouring into the continuous caster, resulting in the slow flow speed of molten steel and seriously affecting the productivity.  

2. the outside temperature is low, the steel water temperature drops fast, with the temperature constantly being cooled down.  In order to solve this problem, the heat preservation ladle can be used to maintain the temperature of the molten steel to ensure that the molten steel will not be sticky when it enters the continuous caster.  

3. Continuous casting billet of continuous casting machine is difficult, and the temperature can be raised by external oxygen blowing, so the continuous casting machine must meet the requirements of "first continuous casting, then oxygen blowing".  At the same time, cooling water is used to spray and cool the billet, and the billet enters the roughing mill after cutting.  

With the acceleration of industrialization and urbanization, and the rapid increase of motor vehicles, the air quality of China's cities is facing unprecedented tests, and the high incidence of diseases caused by haze weather is becoming the focus of public concern.  Energy conservation and environmental protection is listed as the key development road in China's national policy. The reason for many times of emphasis is the continuous shortage of energy in China. The cruel reality has been constantly calling for each of our mill production line manufacturers to reconsider the future development direction of the rolling mill.  Resources drying up, the power supply of the power sector, the increasing deterioration of the environment, which has already been obvious reality facing the front of every one of us, only everybody together to make our best effort, to reduce the pollution to the environment, take energy conservation and environmental protection course of steel rolling equipment, energy-saving and high efficiency is the main melody of the development of rolling mill in the future,  Only in this way can the development of rolling mill go further. 

 For the current steel rolling equipment in rolling wastewater, dust and noise, although there has been a lot of improvement, but with those large international steel manufacturers, China's steel industry has also encountered some problems, production and sales growth is still a big gap, but with a big direction, will work harder.  The speed ratio of the rolling mill and the reducer is corresponding, the rolling mill can save water to a great extent, and save gas for the steel rolling furnace. The heating capacity of the steel rolling furnace can reach ten tons per hour.  As soon as possible to commit to the steel rolling enterprise action plan into implementation from the overall comprehensive benefits are very considerable.  Rolling mill can greatly reduce manual operation, the billet with a roll for water cooling, all as and consider whether to provide more free carbon emission quota for the European steel industry cleaning water can achieve recycling, and then pump to filter the new water area.  In this way, the balance of wastewater is not only solved, the oxide scale of the billet in the washing water is recovered, and the precipitation is carried out, because the water flow is sufficient, the water consumption in the process of steel rolling is guaranteed, and the rolling process and rolling efficiency of automatic rolling mill are improved.
