Our engineers, together with steel mills and metallurgical research institutes, have developed an environmentally friendly bonding agent after many tests and researches. We have achieved good results. Smoke-free and odorless, easy to turn the bag. It is welcomed by steel mills and customers. For improving the environment of steel mills, reduce costs, has an immeasurable market prospects. In addition to meeting the production needs of enterprises, this product is now used to promote the use of fraternal units.

Luoyang City Kelder Refractories Co., Ltd. fully examined China's iron and steel enterprises, combined with local resource advantages, and deployed professional and technical personnel after market demonstration and technical research to develop a siliceous dry material to meet the market requirements, which is well received by customers. Put on the market for 5 years has achieved significant social and economic benefits.

Characteristics of siliceous dry compounds

1. It has the advantage of cost-effective and low price.

2. It has the characteristic of simple baking. Available wood, diesel fuel and other baking; no gas conditions of small steel mills are also applicable.

3. Because of the lower bulk density, the heat preservation performance is better than magnesium dry material. 　Silicon dry material to fill the blank of the steel drawing process conditions 10-24 hours, reducing costs, has a broad market prospects and competitiveness.

The electric furnace cover lining is the weak link of the whole furnace body. Due to the influence of operating factors and structural factors, it puts forward harsh requirements on the resistant material. Factors affecting the life of the furnace cover are mainly: 1, thermal shock. Arc heating, temperature changes caused by the discharge of steel and cover movement; 2, chemical erosion. Slag steel splash to the surface, causing chemical erosion, as well as the furnace CO, CO2, SiO2, etc.; 3, arc radiation. Arc heating heat radiation caused by the melt loss; 4, high-speed dust extraction in the furnace to form a high-speed airflow wear; Therefore, the refractory materials used in the furnace cover requires good thermal shock, the slag high-temperature splashing resistance to erosion, as well as the integrity of a good, solid structure does not crack and so on.

According to the requirements, our company utilizes the modern material science and technology, according to the principle of compound phase modification, scientific configuration and elaborate production, and successfully developed a long-life type castable prefabricated block, which contains two series: one is Aluminum - Chromium system. It can be used in all kinds of high-power or ultra-high-power electric furnaces. 　　The other series is aluminum-spinel system, which is especially useful for the triangle area at the top of the furnace. 　　This kind of castable material is cited to the intermediate package flow stabilizer, impact brick and slag wall has achieved good results.
