Problems solved by technology

[0003] In the past, when the stainless steel protective plate was used for the lining of the annealing furnace, only one kind of fixing hole (Φ35mm) was provided. During installation, the overall installation was carried out from top to bottom according to the number, and then the secondary adjustment, fixing and welding were carried out from top to bottom. ; During the long-term high-temperature use of the annealing furnace lining, the stainless steel protective plate will be deformed to varying degrees, and the refractory fiber in the furnace lining may be exposed in the furnace, and the surface particles will fall off and cause furnace pollution, which will affect the surface quality of the strip steel

Embodiment Construction

[0014] According to the furnace lining structure and operating temperature, the present invention first determines the positioning hole mode, layout position and pre-pressing mode size of the stainless steel protection plate, and then processes and manufactures it; during installation, it uses a full house scaffolding platform to carry out accurate measurement and laying out from bottom to top , Anchor bolt welding, and then pave the ceramic fiber blanket layer by layer from top to bottom, and install the stainless steel protection plate layer by layer. Once in place, the furnace lining installation is completed safely, efficiently and with high quality.

[0015] Construction steps of the present invention:

[0016] Analyze and optimize the drawings to determine the pre-pressing method and size: according to the furnace structure size, operating temperature and the material of the stainless steel protection plate, determine the method and size of the stainless steel pre-pressin...

Abstract

The invention relates to an annealing furnace lining, in particular to a stainless steel protective plates for the annealing furnace lining. A fixing method comprises the steps of according to a furnace lining structure and a using temperature, firstly determining a positioning hole mode, a laying position and a prepressing mode and sizes of the stainless steel protective plates, and then conducting processing and manufacturing; during installation, a mantanghong scaffolding platform is utilized to conduct precise measurement and paying off and welding anchoring bolts from bottom to top, then executing modes of laying ceramic fiber carpets layer by layer and installing stainless steel protective plates layer by layer, the work is finished at one time, and the furnace lining installation is safely and efficiently finished. According to the fixing method of stainless steel protective plates for the annealing furnace lining, manual waste is reduced, the installation cycle is shortened, the situation that the stainless steel protective plate slides directionally and in the long using process is effectively controlled, the deformation is reduced, and the band steel surface quality influenced by pollution inside a furnace caused by shedding of fireproof material particles in the furnace lining is prevented.

Description

technical field [0001] The invention relates to an annealing furnace lining, in particular to a stainless steel protection plate for the annealing furnace lining. Background technique [0002] The continuous annealing furnace includes a preheating chamber, a heating chamber, a soaking chamber, a slow cooling chamber, a fast cooling chamber and an aging chamber. . The structure of each furnace chamber is basically independent, connected together through the passage between furnace chambers, the height reaches 25m ~ 30m, and the width (clearance) in the furnace does not exceed 2.5m. The material of the stainless steel lining plate is mostly SUS304s or SUS310s according to the temperature of the furnace chamber. [0003] In the past, when the stainless steel protective plate was used for the lining of the annealing furnace, only one kind of fixing hole (Φ35mm) was provided. During installation, the overall installation was carried out from top to bottom according to the numbe...
