Example Embodiment

[0016] In order to further describe the present invention, the present invention will be described in more detail below in conjunction with examples:

[0017] 1. Take the heating furnace of a hot continuous rolling mill as an example. The heating temperature of the heating furnace is 1350℃, the output is 120t / h, and the billet push-steel heating furnace adopts vaporization cooling method and double drain beam pipe. The conventional method is adopted, and the wrapping is a traditional two-layer structure. The thermal insulation layer adopts 20mm thick 0.2w / m.k zirconium fiber, and the working layer adopts 50mm thick 1.5w / m.k low cement castable. The evaporation cooling loss is 7.37%.

[0018] Four square fixed blocks 2 are welded on the outer surface of the furnace bottom water pipe 1 per meter of the water beam pipe circumference, and a semi-cylindrical heat-insulating material with a thermal conductivity of 1.0w / mk is used to prepare a semi-cylindrical prefabricated block A3 that...

Abstract

The invention discloses a heating furnace water beam binding method. A fixing block is arranged on the outer surface of a furnace bottom water pipe. A semi-cylindrical precast block A and a semi-cylindrical precast block B are prepared from heat insulating materials with the heat conduction coefficient smaller than 1.0 w/m.k and are matched to form a cylinder, and a groove in the same size as the fixing block is arranged in the cylinder. The precast block A and the precast block B are installed on the outer side of the furnace bottom water pipe, and the groove inside is rightly matched and connected with the fixing block, and finally the connecting position of the precast block A and the precast block B and the combination positions of the precast block A, the precast block B and the furnace bottom water pipe are sealed with high-temperature cement gum.

Description

technical field [0001] The invention belongs to the field of heating furnace energy saving, and in particular relates to an adiabatic wrapping method capable of reducing the heat dissipation of the water beam of the heating furnace. Background technique [0002] The current method of wrapping the water beam of the heating furnace is generally that the first layer outside the metal water beam tube is a heat insulating material, and then a castable, which plays the role of heat preservation and heat insulation. However, due to its large wrapping area and good thermal conductivity, during the production process, due to the large heat absorption of the water beam, the local temperature on the surface of the billet will drop (commonly known as the black mark of the water pipe). Heat loss in the furnace. [0003] CN200920254649.0 discloses a wrapping block for water pipes at the bottom of a heating furnace, which is used to solve the problem of heat dissipation loss of water pipe...
