Shandong Yiranwalking beam reheating furnaceBy adopting mechanized operation methods, the capacity and output of the furnace can be increased, with advantages such as good heating quality, flexible thermal control and operation, and good working environment. The furnace length is not limited by the length of the pushing steel, and the production efficiency is high. The Yiran step heating furnace adopts a step bed refractory material furnace bottom or water-cooled step beam method, which can be applied to high-temperature heating. Stepper heating furnace can be applied to the heating of alloy steel slabs, billets, billets, and even steel ingots before rolling. The bottom of a walking beam heating furnace is mainly composed of a movable part and a fixed part, and can be divided into walking beam type, walking bottom type, and walking beam bottom combination type heating furnaces according to their different structures.

Advantages of Yiran Stepping Heating Furnace:

1. The stepper forging heating furnace can heat large slabs, irregular billets, as well as small and thin steel billets that are difficult to heat with ordinary heating furnaces.

2. Workpiece heating is flexible and adaptable. With a fixed furnace length, the number of materials loaded in the furnace can be adjusted by changing the distance between the steel materials to meet the needs of the rolling mill production and steel grade changes. By adjusting the step cycle, the heating time of the steel material in the furnace can be changed to meet the needs of different steel grades and heating speeds.

3. The heating quality is good and the steel temperature is relatively uniform. Because there is a certain distance between the steel materials in the walking furnace, the heating area of the steel materials is increased, which reduces the temperature difference of the steel material section. In addition, since the movement of the steel material relies on the movement of the furnace bottom and does not slide directly on the furnace bottom, there will be no scratches on the lower surface of the steel billet.

4. The length of the furnace is not limited by the steel pushing ratio, which can avoid accidents such as arching and sticking during the production process, and can also increase the furnace length to improve the production capacity of the furnace.

5. The Yiran step heating furnace is flexible and convenient. It can remove the steel material from the furnace according to the process needs to avoid oxidation and decarburization caused by the steel material staying in the furnace for a long time. It can also keep the steel material stagnant in the furnace to adapt to the changing production needs of the rolling mill.

6. A stepper heating furnace can provide detailed calculations and control of the heating speed and time of steel materials inside the furnace, which is beneficial for achieving automation of the entire heating process.

7. The stepper heating furnace has a high degree of automation: it adopts fully automated control, and the furnace temperature control adopts double cross limit control with dynamic limit bands, achieving second and third level automatic control;

8. The stepper heating furnace is equipped with a thermal automation control system, which controls the air to gas ratio and reasonable furnace pressure control, resulting in low heat loss and energy consumption.
