1. Classification of steel rolling heating furnaces: According to the process, they are divided into wire, plate, profile heating furnaces, etc.; according to the heat source, they are divided into natural gas furnaces, oil furnaces, coal furnaces, electric furnaces, etc.; according to the structure, they are divided into chamber type, slot type, and trolley Type, pit type, stepping type, vibrating bottom type, continuous type, etc.; according to thermal system and operation mode, it is divided into constant temperature furnace, intermittent temperature change furnace and continuous temperature change furnace.

The furnace space is as small as possible under the condition of ensuring fuel combustion, which is also the principle followed by Zhongwei environmental protection design. The height and length of each section of the furnace have a great influence on the heat transfer in the furnace, which directly affects the heating of the furnace and the utilization of fuel. When considering the height of the furnace, it is necessary to ensure that the fuel is fully burned and the furnace gas is filled. .

The length of the furnace body is determined by the total heating capacity, but in order to reduce energy consumption and increase the heat utilization rate of the furnace, the length of the furnace body can be appropriately increased. The short furnace body and high-temperature flue gas will not be fully utilized, and the exhaust gas will take away a lot of heat energy. Therefore, the length of the furnace body is appropriately extended and the thermal efficiency is improved. The application of the ZW series diesel burner in the rolling furnace is particularly prominent. Under certain heating conditions, the higher the hearth load, the lower the thermal efficiency and the higher the energy consumption. Conversely, as the furnace bottom load decreases, the heat loss taken away by the exhaust gas will be significantly reduced. If other conditions remain unchanged, if the furnace body is appropriately extended, although the increase in furnace bottom water pipes and furnace body masonry will increase this part of the heat loss, it is far less than the energy saved.

2. The concept and method of heat balance is an indispensable part when analyzing the production efficiency and fuel consumption of the furnace. The heat balance of the furnace is the application of the law of conservation of energy to the furnace thermal work. It means that the heat absorption and expenditure of the furnace must be equal. That is, according to the principle of equal heat income and heat expenditure, how much energy is supplied to the furnace, how much is lost, and how much is used.

The purpose of preparing the heat balance is twofold; one is to more accurately determine the fuel consumption of the furnace through heat balance calculation, and design the combustion system based on this. At the same time, various heat losses are predicted, and the advantages and disadvantages of the furnace design can be judged. Second, through the actual measurement of the heat balance, it is possible to evaluate the performance of the furnace in the heat loss of heat utilization, and then find a more energy-saving solution.

Steel rolling heating furnaces are classified according to different fuels: oil-fired steel rolling heating furnaces, gas-fired steel rolling heating furnaces, and oil-fired steel rolling heating furnace projects are mainly in Africa, with diesel and heavy oil heating furnaces mostly.

Features of Diesel Steel Rolling Heating Furnace Burner:

1. Fuel saving. Diesel burner or heavy oil adopts flame-stabilizing plate structure, adopts air compressor compressed air atomization method, fuel/air mixing is even, and combustion is complete. If high-viscosity heavy oil is used as fuel, auxiliary heating measures must be adopted to enhance the fluidity of heavy oil and facilitate atomization and combustion.

2. Suggest an automated control system. The burners of foreign oil-fired steel rolling heating furnaces generally adopt simple manual control functions. Especially using heavy oil as fuel, it is easy to block the heavy oil burner. In response to this situation, Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. designed effective measures to deal with the blocked burner to minimize the degree of blockage.

Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. undertakes the "turnkey" project of diesel steel rolling heating furnace and heavy oil steel rolling heating furnace, and is responsible for: design, foreign construction, installation, commissioning and training "turnkey" technical services.
