Gongyi Yuying Refractory Co., Ltd. is an industrial and trade enterprise integrating research and development, mainly producing unshaped and shaped refractories.

The main raw materials for firebricks currently on the market are: raw bauxite, high-content calcined bauxite, refractory clay, white corundum, brown corundum, silicon carbide, etc. The most common firebricks on the market: clay refractory bricks and high alumina refractory bricks.

The production process of refractory bricks is: raw materials, crushing, crushing, screening, silo, batching, mixing, forming, drying, firing, sorting, packaging, and shipping. There are many sizes of refractory bricks, generally the size of the fixed abrasive is standard size refractory bricks. The special size requested by the customer is a special-shaped brick. We can customize and produce the special size mold for the customer.

How many types of manufacture of fire bricks?

According to the physical and chemical properties of refractory bricks, it is divided into the following types:

Acid refractory bricks: mainly silica-alumina series, used for various glass, ceramic vaults and some load-bearing parts. Advantages High temperature resistance, it is recommended to be used in equipment above 600°C.

Alkaline refractory bricks are mainly made of alkaline oxides. According to different raw materials, they are divided into magnesia refractory bricks, dolomite bricks, forsterite refractory bricks and so on.

Carbon-containing refractory bricks are mainly produced from carbon or carbon compounds as the main raw materials. According to the different forms of carbon, they are divided into graphite refractory bricks, silicon carbide refractory bricks, and carbon bricks.

Thermal insulation refractory bricks are characterized by high porosity, low body density, and low thermal conductivity. Common heat-insulating refractory bricks are: high-aluminum heat-insulating lightweight refractory bricks, clay-based heat-insulating lightweight refractory bricks, diatomite heat-insulating lightweight refractory bricks, floating bead bricks, etc.

According to the main raw materials of refractory bricks, it is divided into: clay refractory bricks, high-alumina refractory bricks, silica bricks, corundum bricks, magnesia bricks, etc.

There are currently any refractory manufacturers in the world, especially in China. Gongyi, Henan is also known as the hometown of refractory materials. Gongyi Yuying Refractory Co., Ltd. has a long history. Its own workshop has been in this industry for more than 20 years, and it has abundant refractory material production and independent research and development capabilities. China is a large raw material supply country with abundant supporting raw materials. Our company has its own bauxite mining area and does not need to be imported. The production cost is advantageous, so the product quality is good and the price is competitive.

 We are the source factory, producing and exporting ourselves, and there is no middleman to make the difference. The company’s investment is mainly in product quality control. Our company has complete testing equipment and experienced testing and quality inspection personnel, and all our products are strictly tested and controlled.
