Furnace lid inversion and furnace lid installing process

Abstract

The invention relates to the field of industrial capital construction and large part installation, provides a furnace lid inversion and furnace lid installing process and overcomes the influence on furnace lid hoisting and mounting operation after a plant roof and a rainproof system are formed so as to safely and conveniently hoist and install a furnace lid. The furnace lid inversion and furnace lid installing process comprises an electric furnace shop formed by a steel structure, a roof and a defensive system, a furnace housing installed in place and including sectioned furnace lids of a peripheral section furnace lid, a middle section furnace lid and of a central section furnace lid, a flat cart for transferring the sectioned furnace lids to a storage yard in a site, a movable hoisting device for hoisting and installing the sectioned furnace lids, a main winch hoisting system formed by a main winch and a cooperating main winch pulley set, an auxiliary winch hoisting system formed byan auxiliary winch and a cooperating auxiliary winch pulley set, an inversion chain for correcting the moving directions of the sectioned furnace lids in the sectioned furnace lid hoisting and installing process, and also comprises a furnace lid inversion and utilization movable hoisting device and a technology for installing a furnace lid through cooperation of winches and pulley sets.

Description

technical field [0001] This technology relates to the field of industrial infrastructure and large-scale installation. It provides a furnace cover inversion and furnace cover installation process, which overcomes the impact on the lifting and installation of the furnace cover after the formation of the factory roof and rainproof system, and can be lifted safely and simply. Transport and install the furnace cover. Background technique [0002] The main body of the nickel-iron electric furnace (also referred to as an electric furnace in this case) is mainly used to reduce metallic nickel, separate slag from ferronickel, and produce thermal reaction sites for ferronickel. [0003] In the prior art, a commonly used electric furnace body mainly includes a base set on the basis of a steel-structured electric furnace workshop, a furnace shell placed on the base, a furnace cover covering the upper opening of the furnace shell, and a furnace cover set on the furnace cover. Furnace c...

AI Technical Summary

Problems solved by technology

[0009] After the furnace bottom insulation is installed, assemble and install the furnace shell on the upper part of the insulation board, because the insulating material is ceramic fiber, its own strength is poor and it is easily damaged by external force, which makes the furnace shell need to be placed in place accurately at one time. The heavy furnace shell brings greater difficulty in installation, and the process causes additional loss of large cranes and labor waste

Secondly, if construction is carried out in the rainy season or in rainy areas, the furnace bottom insulation will be completed before the rainproof system on the roof of the factory building is completed. It is a big challenge to insulate and prevent rainwater in large areas before the rainproof system is formed on the roof of the factory building. If the insulation is soaked in water, the insulation requirements cannot be met and rework is required

[0010] Like the furnace bottom insulation, the construction of the furnace cover and insulation also faces the above problems, and the furnace cover is hoisted by a large crane to occupy the entire space above the furnace cover. Other processes above the furnace cover cannot be carried out normally, and the limited ground space is hoisted. The large cranes covered by the cover occupy a large part, and the ground space left for other processes is also quite tight.
