The use of refractory plastics on steel rolling heating furnaces requires following a series of strict steps and specifications to ensure that they can effectively protect the heating furnace and extend its service life. Here's a detailed explanation of the process:
1,Preparation before construction: First, make sure that the inside of the heating furnace is dry and clean, free of debris and dust. This is to ensure that the refractories plastic can closely fit the furnace wall and fully exert its protective effect.
2,Material selection and preparation: Select appropriate refractories plastic according to the specific conditions and requirements of the heating furnace. Make sure the selected material has good high temperature resistance, wear resistance and chemical stability.
3,Construction process: During the construction process, the construction temperature should be strictly controlled to ensure that it is not lower than 5℃. At the same time, fire-resistant plastics should avoid contact with water during construction to prevent their performance from being affected. In addition, when ramming the construction body, it should be rammed in layers to ensure density to ensure even distribution and tight combination of refractory plastics.
4,Oven and maintenance: Before drying, the mold should be removed as early as possible to allow the construction body to dry naturally. During the oven process, the heating rate should be controlled to avoid cracking of the refractories plastic due to excessive speed. After the oven is completed, necessary maintenance work should be carried out to ensure complete curing of the refractories plastic.
5,Use and maintenance: During the use of the heating furnace, the condition of the refractories plastic should be checked regularly to ensure that it is intact. If damage or wear is found, it should be repaired or replaced in time. In addition, the inside of the heating furnace should be cleaned regularly to maintain a good working environment.
In short, the use of refractory plastics on steel rolling heating furnaces requires following a series of strict steps and specifications. Through correct use and maintenance, the heating furnace can be effectively protected and its service life extended, thereby increasing production efficiency and reducing maintenance costs.
