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

SEPPE Fluorite is a natural mineral, the main component is calcium fluoride(CaF2).The process of fluorspar lumps is relatively simple. After the natural fluorite ore is exploited, they will be directly processed into the size required by customers through physical processing. Generally, the size ran

Fluorspar powder (Fluorite powder) can be divided into dry powder and wet powder.Mainly used in chemicaUnder the epidemic situation of Xinxiang crane foreign trade enterprise development countermeasuresl industry, metallurgical industry, buliding materials industry and other special industry. Acid g

Mullite refers to a series of minerals composed of aluminosilicate and it is a high-quality refractory raw materials.1. Mullite is used in the production of high temperature refractories, ceramics, metallurgy, foundry, electronics and other industries. It has high temperature resistance, high str

Calcined bauxite is one of the principal ore of aluminum.Rotary kiln calcined bauxite is obtained by calcining superior grade bauxite at high temperature (from 850℃ to 1600℃) in the rotary kiln. This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57%

Chinese Lantern Festival is coming.Make your best wishes and let lanterns bring it to the sky.Good luck to all of you.SEPPE always stay with you.
