Problems solved by technology

[0013] The purpose of this technology is to provide a process for electric furnace bottom insulation and furnace shell inversion, using this process to install the insulating plate between the furnace shell and the base, avoiding the influence of external conditions on the construction, and also overcoming the problems caused by the structure of the insulating plate itself. Poor strength, easy to be damaged by external force when installed in normal installation sequence, to ensure the installation quality of the insulation board

Abstract

The invention relates to the field of industrial capital construction and large piece installation, and provides an electric furnace hearth insulation and furnace shell inverted installation technology. By adopting the technology for installing an insulation plate between a furnace shell and a base, influence caused by outside conditions to construction is avoided, the defect that an insulation layer is naturally poor in structural strength, and thereby is prone to being damaged by external force during the installation process of a normal installation procedure is overcome as well, and the installation quality of the insulation plate is guaranteed. The electric furnace hearth insulation and furnace shell inverted installation technology comprises the construction technology of installingthe base, the construction technology of installing the furnace shell on the base in a splicing manner, and the construction technology of arranging the insulation plate between the base and the furnace shell in a lining manner.

Description

technical field [0001] This technology relates to the field of industrial infrastructure and large-scale installation. It provides a process for electric furnace bottom insulation and furnace shell inversion. This process is used to install the insulating plate between the furnace shell and the base, which avoids the influence of external conditions on the construction and overcomes the Due to the poor structural strength of the insulating layer itself, and the defect that it is easily damaged by external force during normal installation sequence, the installation quality of the insulation is guaranteed. 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-...
