1）High Temperature Burnt Slide Plate
This product adopts tabular alumina, carbonaceous material and zirconia-containing material as main raw materials, adds in high performance antioxidants, uses phenolic resin as binder, formed under high-pressure and burned under high temperature. The slide plates have the advantages of high strength, good erosion resistance, thermal shock resistance and good stability etc.,
mainly used in large and medium-sized ladle.
The physical and chemical properties of high temperature burned Al-C and Al-Zr-C slide plate are as follow:

2） Low Temperature Burnt Slide Plate
Tabular alumina, zirconia-containing material and spinel as major raw materials, adding in special metal, using phenolic resin as binder, being burned under low temperature to produce the products,
which have the advantages of low carbon content, strong strength under high temperature and good thermal shock resistance stability. This product mainly used in small and medium-sized ladle.

3） Unburned Slide Plate
To meet the needs of continuous casting and reducing steelmaking costs for small and medium-sized steel plant, we have developed unburned slide gate series products—unburned Al-C slide plate, which adopts tabular alumina and high pure graphite, adds in proper amount of additive and antioxidant, uses phenolic resin as binder, pressed under press machine. The unburned Al-C plates have the following features: no need to be burned, tar impregnated and distilled, simple processing. This product mainly used in small and medium-sized ladle.
The physical and chemical properties of unburned Al-C slide plate are as follow:

1. Serivice life depends on steel-making condition, refractory slide gate and different operation mode。 The above service life we supply is based on the condition of more than 100 Tons ladle.
2. For composited slide plate, we can mark different material in different part and detailed index according to the drawings.
3. Delivery time depends on the drawings. If it needs to make new mould, then we will decide then. In general it is 35-50 days.
