Lightweight ceramic fiber module refractory thermal insulation material for ladle cover insulation

At present, the use of ceramic fiber lining has become institutionalized and normalized, and the materials that must be used are specified in the kiln overhaul
Ceramic fiber furnace lining has ceramic fiber module, ceramic fiber blanket and other refractory and thermal insulation materials

Ceramic fiber module is also called ceramic fiber module
With & ldquo; Module & rdquo; With the development of production technology, the expansion of varieties and the improvement of technical performance, the fiber lining of industrial kiln has broken through the traditional structure and construction methods and presented a new look
This is manifested in replacing the traditional layered lining structure with various stacked module and prefabricated module lining
Ceramic fiber module is a kind of high temperature resistant material with excellent performance
Adding aluminum, zirconium and other substances can make fiber modules of different temperature grades
Ceramic fiber module has the excellent characteristics of low heat storage, energy conservation and environmental protection, high temperature insulation and corrosion resistance, light weight and convenient construction
It is widely used in industrial fields such as iron and steel, metallurgy, kiln, heating device and so on

Compared with earlier castables, ceramic fiber lining has the following advantages:
(1) It has good thermal insulation performance, reduces heat loss, and is resistant to quench and heat and mechanical vibration

(2) Ceramic fiber module is a lightweight refractory material, which can replace the traditional heavy refractory castable, effectively reduce the bearing capacity of the transmission structure of the ladle cover and make the automation of the ladle cover & ldquo; Hinged system & rdquo; Become possible

(3) The whole fiber furnace lining has the advantages of simple construction, convenient maintenance and no oven drying
The overall structure of the ladle cover lining is uniform and the surface is flat and compact; Convenient construction and easy maintenance

The ladle cover adopts light ceramic fiber module as fire-resistant and thermal insulation material, which can reduce the weight of the ladle cover; Improve the temperature and uniformity of molten steel and improve the quality of steel; Extend the service life of the lifting device; Extend the service life of the ladle cover to more than 2000 heats; Reduce the shell temperature and heat loss

Precautions during use of ladle cover:
Because the ceramic fiber module is a lightweight thermal insulation material, be careful not to collide during the lifting of the ladle cover
In addition, the ladle edge should be kept clean to avoid large pieces of steel slag scraping the ceramic fiber cotton
