Description

Technical Field

[0001] This utility model relates to the technical field of heating furnace equipment, and in particular to a water beam insulation structure for a heating furnace. Background Technology

[0002] The steel rolling heating furnace is a crucial large-scale piece of equipment in the steel rolling workshop of any steel plant. The furnace is used to heat and soften steel billets, making them easier to roll later. In commonly used heating furnaces, a heat-resistant sliding block is welded to the upper part of the water beam. The steel billet to be heated is placed on the heat-resistant sliding block of the water beam, and is pushed forward by a billet pushing mechanism. The water beam, which bears the high temperature and weight of the steel billet within the furnace chamber, includes water beam columns. These columns are internally cooled by water to maintain sufficient strength in the high-temperature environment to support the weight of the steel billet above.

[0003] The existing heating furnace water beam consists of a central water beam column, covered with a layer of approximately 20mm thick aluminum silicate fiber, and an outermost working layer of refractory castable. Heat-resistant stainless steel anchor bolts are welded to the water beam column to anchor the outer castable layer. In actual use, the furnace temperature reaches 1300 degrees Celsius. The poor insulation performance of the water beam increases the furnace's energy consumption and, in severe cases, can cause the water beam steel pipes to burn out, resulting in a short service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heating furnace water beam insulation structure that increases the service life of the water beam and reduces the energy consumption of the heating furnace.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a water beam insulation structure for a heating furnace is provided, including a water beam column and anchor nails fixed thereon. The surface of the water beam column is provided with, from the inside to the outside, a flexible nano blanket, a zirconium fiber blanket, an explosion-proof self-flowing material, a water beam furnace lining, and a thermal protective coating.

[0006] The beneficial effects of this utility model are as follows: The water beam insulation structure of this utility model changes the existing situation where the water beam insulation performance of the heating furnace is insufficient and easily damaged by vibration. The following settings reduce the energy consumption of the heating furnace and prevent the flexible nano-blanket from pulverizing, prevent the zirconium fiber blanket and water beam furnace lining from falling off, and strengthen the structural integrity. The first layer is a flexible nano-blanket for heat conduction, reducing heat dissipation, minimizing heat storage, and significantly improving energy efficiency. The second layer is a zirconium fiber blanket, resistant to high temperatures up to 1430℃, with excellent heat insulation and heat preservation properties. The third layer is an explosion-proof self-flowing material with high-temperature adhesion performance up to 1400℃ and resistance to cracking after bonding. The fourth layer is the water beam furnace lining, protecting the original castable and extending the service life of the castable covering structure; reducing heat loss from the heating furnace. The fifth layer is a thermal protective coating with a long-term operating temperature of up to 1800℃, effective wind resistance, and protection of fiber lifespan even under high wind speeds.
