Problems solved by technology
However, due to the large number of equipment in the furnace area, the matching gap between the radiant tube and the furnace is small, and the radiant tube is often deformed after high temperature, making it extremely difficult to insert and pull the radiant tube into and out of the furnace (generally, a chain hoist is hung on the nearby steel structure. Forcibly pulling out the radiant tubes), resulting in long time-consuming insertion and extraction of radiant tubes. The insertion and extraction of a single set of radiant tubes takes nearly 3 hours, which greatly reduces the construction efficiency of radiant tube replacement
In addition, the special spreader is generally long and has a large counterweight at the rear, so it cannot be placed directly on a small maintenance platform. Therefore, the entire insertion and removal operation needs to be lifted by a crane, which seriously occupies the truck in the factory. Other items in the factory that need to be hoisted by crane have a great impact, often causing staff to sit down

The invention provides a device and method for replacing a radiant tube. The device for replacing a radiant tube includes a suspension beam for connecting with a crane, a clamping mechanism, and a base capable of being positioned on a furnace. The clamping mechanism includes a main body frame , the back plate connected with the main body frame, the connector fixed on the back plate, the plug-in jack installed in the main frame, and the top plate fixed at the end of the piston rod in the plug-in jack, the hanging beam and the main body The frame, the base and the main frame are detachably connected, the connecting piece is used for detachable connection with the radiant tube, and the top plate is used for matching with the furnace. When the application replaces the radiant tube, the plugging jack acts on the furnace, which can easily overcome the large frictional force generated when the radiant tube enters and exits the furnace, facilitates the plugging and pulling operation of the radiant tube when entering and exiting the furnace, and greatly improves the replacement of the radiant tube. Construction efficiency and construction safety.
Description
Technical field[0001]The invention relates to the field of radiant tube replacement, in particular to a device and method for radiant tube replacement.Background technique[0002]Major domestic steel plants have continuous annealing, hot-dip galvanizing and other units. The process section of these units is equipped with a continuous annealing furnace. The furnace zone can heat treat the strip steel in the furnace to improve strip performance and meet product needs. The continuous annealing furnace of these units is generally a vertical structure. In order to ensure the production speed and meet the requirements of the process, the strip steel in the furnace is generally several hundred meters, and most of the furnace areas use radiant tubes to heat the strip steel;figure 1 As shown, the radiant tubes 100 installed in the furnace 200 are evenly arranged on both sides of the strip along the strip running route, and hundreds of sets of radiant tubes 100 are often arranged in one product...
