Refractory materials are the main building materials of glass melting furnaces, and they have a decisive impact on the quality of glass, energy consumption and even product costs. The development of glass melting technology largely depends on the advancement of refractory material manufacturing technology and the improvement of quality.

The cover of the electric furnace is a spherical structure with electrode holes and smoke exhaust holes. The outer ring part is called the main furnace cover, and the middle part is called the small furnace cover (also known as the triangular area). When loading materials, the furnace cover can be moved away.

Overburning and lumping are common phenomena in the lime production process. They not only affect product quality but, in severe cases, can have a fatal impact on the production process, refractory materials of the kiln body and other equipment. This article analyzes the causes of overburning and tumor formation, general treatment methods for tumor formation, and preventive measures, effectively avoiding the occurrence of tumor formation.

A kiln is a space capable of generating high temperatures, and the materials that make up this space are called kiln construction materials. The construction materials should include two major categories: refractory materials and thermal insulation materials (or heat insulation materials). In addition, to enhance the structural strength of the kiln body, the materials used for furnace construction should also include common building materials (such as ash bricks, etc.) and metal materials, etc.

Burn-through of the hearth and bottom of the furnace is the most serious safety accident in blast furnace ironmaking production, which can cause significant loss of life and property to the enterprise and even terminate the production of the first generation of blast furnace service.

The requirements for refractory materials in non-ferrous metal smelting are rather complex. They must not only have sufficient high-temperature resistance but also possess certain high-temperature strength. At the same time, they need to have good resistance to slag erosion and the ability to resist the scouring of furnace slag and flue gas. Therefore, there are strict requirements for the selection of refractory materials in the furnace.

For the iron tapping channel, apart from the material itself, the construction method is very important. It is briefly described as follows:

The material of the iron tapping ditch

Maintenance of lime kiln

The production process of tempered glass is as follows: glass pre-treatment (cutting, drilling, grinding), a washing and drying, a furnace heating, an air shed cooling, a tempered product inspection.
