The water-cooled beam can be cooled by water to ensure the operating environment of the furnace. Usually it is U-shaped structural design, but it is limited to the influence of water-cooled pipe material and water pressure fluctuation. This kind of beam is more prone to water leakage and collapse, causing shutdown and affecting production. Leakage is easy to flood the motor and cause spare parts to be consumed.
Therefore, the U-shaped structural beam structure was changed to the form of the waterless cold arched structure, and the material was made of high temperature resistant ZG40Cr25Ni35Nb. This structure can meet the 900 °C process temperature and avoid metal bending. In practical application, the refractory thickness is increased around the steel structure, and the density of the anchor is increased on the lower part and the two sides of the steel structure, so that the integral structure of the waterless chilled beam is integrated, and the temperature fluctuation is caused to cause the castable and the steel structure to be biased. Move the problem.
The characteristics of the transformation are: 1), the integral arch type and the partial I-type mechanism are integrally cast, and the U-shaped structure connected by the welding method and the water-cooled form is discarded, and the joints are leak-free and the fracture is caused by the collapse. 2), good temperature resistance, the new material ZG40Cr25Ni35Nb has good temperature resistance, and it is integrated with the castable material during installation, relying on each other. The sinking deformation force is jointly assumed by the castable and the waterless cold beam steel structure, which is greatly extended. The applicable life. 3), the benefits are good. The cost of renovating a heat treatment furnace is 100,000 yuan, and the corresponding consumption of circulating water, circulating water heat loss, and gas consumption caused by accidents is about 3 million yuan per year.
This new type of water-cooled beam transformation was practiced by Wuyang Iron and Steel Rolling Mill and successfully applied to the 1#, 2#, 3# heat-treated car bottom furnace of the plant. After the transformation, the waterless cold beam has good mechanical properties and strength under high temperature conditions. Ensure the operating environment and normal operation of the furnace. This kind of transformation can meet the production requirements, has good social and economic benefits, and has a large promotion value.
