Embodiment Construction

[0026] The energy-saving fixing method of the anchor nail provided by the present invention is as follows: first, the anchor L-shaped steel plate 2 is welded on the furnace shell, and the anchor nail is fixed through the anchor nut before the anchor steel plate 5 is installed, and then through the bolt nut Fastener 3 installs the anchoring steel plate 5 on the anchoring L-shaped plate 2, so that the rows of anchoring nails are installed; install the next row of anchoring nails according to the above steps until the entire furnace is filled, and then install the refractory fiber 6, Realize fixing the refractory fiber 6 on the furnace wall steel plate 1 of the vertical continuous annealing furnace.

[0027] see figure 1 , the present invention specifically adopts the method comprising the following steps:

[0028] The first step is to weld and anchor the L-shaped steel plate part 2 on the furnace wall steel plate 1;

[0029] In the second step, a plurality of anchor nails are...

Abstract

The invention relates to an energy efficient fixture method for anchor nails. The method is as follows: welding an anchor L-shaped steel plate (2) on a furnace shell, fixing the anchor nails by anchor nuts before the installation of an anchor steel plate (5), and then installing the anchor steel plate (5) on the anchor L-shaped steel plate (2) through a bolt and nut fastener (3) to finish the installation of a row of anchor nails; installing the next row of anchor nails according to above steps until the whole furnace is filled up, and then installing refractory fibre (6) to realize that the refractory fibre (6) is fixed on the furnace wall (1) of a vertical continuous annealing furnace. In the invention, the carbon steel anchor L-shaped steel plate is adopted, and a carbon steel welding rod can be used for welding, thereby saving welding lost; only two connection points for a plurality of anchor nails are arranged on the furnace shell, thus reducing the number of a heat bridge, reducing heat loss and saving energy consumption; and the invention also has the advantages of saving labor cost, improving the fixing quality of the anchor nails and improving working efficiency.

Description

technical field [0001] The invention relates to the field of fixing refractory materials, in particular to an energy-saving fixing method for anchor nails used for refractory ceramic fibers in a vertical continuous annealing furnace. [0002] 2. Application of refractory ceramic fiber in vertical annealing furnace Background technique [0003] In large-scale continuous annealing lines, the annealing furnace configured is generally a vertical continuous annealing furnace, which is mainly composed of a preheating section, a heating section, a slow cooling section, a fast cooling section, an overaging section, a final cooling section, and water quenching. Its length can generally reach about 150 meters, and its height can reach about 24 meters. The vertical continuous annealing furnace is mainly used for crystallization annealing after rolling of cold-rolled strip steel, eliminating cold work hardening, and providing thin strip steel annealed coils with excellent performance a...
