Clay insulated lightweight firebrick Refractory Materials Iron and steel smelting

Product introduction

Refractory fired from refractory clay or other refractory materials. Light yellow or brown. It is mainly used in building smelting furnace and can withstand high temperature of 1580 ℃ - 1770 ℃. Also called refractory brick. Refractory of certain shape and size. According to the preparation process, it can be divided into sintered brick, non sintered brick, fused cast brick (fused cast brick) and refractory and heat insulation brick; It can be divided into standard brick, ordinary brick, special-shaped brick, etc. according to shape and size. It can be used as the structural material of high-temperature building materials, building kilns and various thermal equipment. It can withstand various physical and chemical changes and mechanical effects at high temperature. Such as refractory clay brick, high alumina brick, silica brick, magnesia brick, etc.

Its properties

1, chemical composition: the main composition determines the quality and characteristics of the refractory
2, volume density: unit volume weight, high density, indicating good density, strength may be high, but the thermal conductivity may be large.
3, apparent porosity: no specific requirements, but as a manufacturer must strictly control the apparent porosity.
4, load softening temperature: also known as high temperature load deformation temperature, this parameter is very important, marking the high temperature resistance of the material
5, thermal shock resistance: resistance to rapid temperature changes without being damaged
6, compressive strength: withstand (room temperature) the maximum pressure capacity

7, flexural strength: the ability to withstand shear pressure

Clay heat insulation light firebrick

Clay heat insulation light firebrick, is made of refractory clay as the main raw material AL2O3 content of 30% ~ 48% heat insulation firebrick. Its production technology adopts burn - out method and foam method. With refractory clay, drift bead and refractory clay clinker as raw materials, adding binder and sawdust, the product with volume density of 0.3 ~ 1.5g /cm3 has been prepared by batching, mixing, forming, drying and firing. The output of clay insulation brick accounts for more than half of the total output of insulation refractory brick.

The Chinese standard (GB 3994 -- 1983) divides the clay heat insulation brick into 10 grades of NG -- 1.5, NG -- 1.3A, NG -- 1.3b, NG -- 1.0, NG -- 0.9, NG -- 0.8, NG -- 0.7, NG -- 0.6, NG -- 0.5, NG -- 0.4 according to the volume density.

Company profile

Henan Geng Hong Industry Co., Ltd. (hereinafter referred to as "Geng Hong industry") was founded in 2007, specializing in the production, manufacturing and sales of complete sets of iron and steel metallurgical equipment, spare parts of metallurgical equipment and metallurgical accessories. At the same time, it cooperates with domestic metallurgical design institutes and European abax group to undertake the engineering design and contracting construction of complete sets of continuous casting and rolling production lines overseas. Over the years, Geng Hong industry has gradually developed into a comprehensive enterprise integrating design, production, sales and service with the core task of meeting customer needs.

Since its establishment, adhering to the principle of "customer as the core, quality as the foundation and service-oriented", Geng Hong industry has successively established and invested in three factories in Anhui, Luoyang and Nanyang, China. Focusing on the needs of iron and steel enterprises, Geng Hong industry has formed a production and sales system of complete sets of metallurgical equipment, equipment spare parts and metallurgical auxiliary materials, It has also obtained the full overseas sales right of refractory products of cooperative factories, and has set up branches or offices in Hong Kong, Taiwan, Vietnam, Malaysia and Iran. After more than ten years of development, the company has a turnover of more than 30 million US dollars in 2020. Its customers involve major domestic steel mills and more than 20 foreign customers. At the same time, the company provides excellent technical services and support of other trade products for foreign customers.

With the continuous development of the enterprise, we strive to explore a wider international market, pursue to provide customers with more excellent quality, efficient product performance and high-quality service, and become an excellent partner of customers。
