Cenosphere (fly ash) is an excellent thermal insulation refractory material and widely used in the production of lightweight castables and oil drilling.It has many characteristics such as fine particles, hollow, light weight, high strength, wear resistance, high temperature resistance, thermal insul

White fused alumina, also called white corundum, is widly used in refractory, casting and abrasive materials.Here is the advantgaes of WFA for casting:1. The shell type made by white corundum has stable thermochemical properties, high fluidity, and no layering problems;2. White corundum has high str

1. Mineral separation and determine the appropriate formula based on the chemical composition of the raw materials. Different grade of the products, also different formula. Such as 45% content alumina grade mullite, 60% content alumina grade mullite, 70% content alumina grade mullite, etc.

* Uniform expansion* Excellent thermal shock stability* High load softening point* Small high temperature creep value* High hardness* Good chemical resistance

As for a foundry sand, ceramsite has few applications below,

Characteristics 1. Low thermal expansion rate to ensure the accuracy of castings; 2. High refractoriness, high thermal conductivity, easy to collapse and not crack; 3. Good fluidity and air permeability, easy to fall out of sand after pouring; 4. Smooth surface, dense structure, saving adhesive 5. G

Recently, due to the impact of the international situation, oil and gas prices have risen sharply, and freight rates have also increased. For now, freight rates are likely to run at a high level in the short term, with an increase of about 10-15%.Affected by the relevant situation and uncertainty fa

Ceramic foundry sand, also known as fused ceramsite, ceramsite sand, jewelry sand, scientific name fused ceramic sand which is made from high-quality bauxite through calcination, electrofusion, granulation, sieving and other processes. It has the advantages of high temperature resistance, no crushin

Sintered Mullite is choosed the natural high-quality bauxite, through multi-level homogenization, calcined at over 1750℃. It is characterized by high bulk density, stable quality, stable thermal shock resistance, low index of high temperature creep and good chemical corrosion resistance performance

The fluorspar briquette we supply is made by metallurgical fluorspar fines and inorganic salt adhesive.It can meet the requirement of ventilation, environmental protection, easy to operation, low phosphorous and sulphor in the process of metallurgy. It can substitute fluorspar lump and is widely use
