High temperature plate air preheater

At present, in the hot rolling heating furnace process waste heat recovery system in the metallurgical industry, the air preheating equipment generally adopts the traditional tube type gas-gas heat exchanger, which is characterized by simple structure and low manufacturing cost, but its heat exchange efficiency and service life Performance indicators such as life are low.

F22-Ⅲ-B type high speed low nitrogen burner

In the production process of metallurgical industry, hot rolling heating furnace is a big energy consumer. At present, there is still a lot of room for improvement in the fine control of walking beam heating furnace. Improving the control accuracy of heating furnace and reducing energy waste and product loss are of great significance to reducing carbon and nitrogen in the whole metallurgical industry. regular walking beam heating furnace refers to the slab with basically the same shape, which moves continuously inside the heating furnace, from the inlet of the heating furnace to the outlet driven by the roller, the burner arranged at the bottom and top of the heating furnace burns the billet of the flame heating furnace to reach the specific process temperature.

Oxygen-fired gun

Based on the design concept of aero-engine combustion chamber, our company developed a low-nitrogen strategy that produces high-speed and high-temperature flue gas to enhance convection, combined with oxygen classification, to control the generation of pollutants.

Ladle roaster

Ladle baking has gone through a series of development processes from using only one gas pipe to using ordinary sleeve burner, high-speed burner, hot air burner, self-preheating burner, regenerative burner and self-priming burner.

Coal pregenerator

It is a specially developed technology for high-efficiency recovery and utilization of waste heat under the low-temperature working of metallurgical heating furnace. It consists of a series of parallel elliptical tubes, which are welded on fixed plates at both ends. In the process of heat transfer, the hot fluid and the cold fluid flow through the outer area of the elliptical tube and the flow channel in the tube respectively, and the heat transfer is realized through cross convection heat transfer.

No. 1 Furnace Air Preheater Renovation Project of Meigang 1422 Line

No. 1 Furnace Air Preheater Renovation Project of Meigang 1422 Line

Shanghai Meishan Iron and Steel Co., Ltd. Hot Rolling Plant 1422mm Hot Rolling Furnace No.1 was put into operation in November 1993, and completed the technical transformation of combustion and cooling system in 2009. The fuel of the furnace is high-coke mixed gas, and regular burners are used for heating and continuous combustion control. The heating furnace is a walking beam heating furnace, and the furnace type is a three-stage heating side-to-side walking beam heating furnace. The heating furnace is divided into preheating section, heating section, heating section and soaking section along the furnace length from the charging end to the discharging end. In order to fully and effectively recover the waste heat of flue gas, a tubular air preheater is set in the flue.

Meigang Hot Rolling Furnace "Reduce Oxidation Burning Loss Software Package" Project

Meishan Iron and Steel Co., Ltd. and Professor Xing Yuming of Beijing University of Aeronautics and Astronautics jointly cooperated in the technical transformation project of "Reducing Oxidation Burning Loss Software Package". The project was established in March 2017 and officially entered the project commissioning period in July, which lasted 9 months. In the course of the project, it has gone through several stages, such as manual debugging, installation of testing equipment, establishment of software package architecture, debugging and improvement of software package, and project evaluation. The results of the project are as follows:
