Product Description

Slide gate plate is the key part in the slide gate systems. Function is to control the flow rate of molten steel.
The slide plate is exposed to high temperature molten steel repeatedly, especially the cast hole part, the erosion is serious, this require the slide plates obtaining features of High strength, excellent corrosion resistance, anti-stripping, to ensure no steel leak during pouring process.
The features of Slide gate plates:
1. Flatness of sliding surface ≤0.05mm
2. High mechanical strength
3. High resistance to contamination of molten steel and slag
4. Excellent oxidation resistance
5. Good thermal shock stability

The seal protection for slide gates are mainly for upper slide plate and upper nozzle; lower slide plate and lower nozzle. After one or two times of casting, lower slide plate and nozzle must be replaced and re-installed. The sealing materials could be gaskets made of fiber or fireclay. To ensure the high cleanliness of molten steel and the uniformity of internal quality of slab.

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 top grade bauxite or corundum, flake graphite as raw materials, adding in proper amount of additives and antioxidant, using phenolic resin as binding materials, formed under friction press machine.

Comparing with burned slide plate, there are no burning process, pitch dipping process and carbonization heat treatment for unburned slide plates, simplifying production process.

Unburned slide plate is not as good as burned slide plates in mechanical strength as well as porosity, however, unburned slide plates have been proved to achieve good using effect and performance in pratice, especially in small and medium size BOF or EAF ladle.

The unburned slide plates can be used together with our B and Q sries slide gate system for ladle under 50 tons, this series slide gate plates are low cost with good performance, widely welcome by many steel plants.

Our company has been in refractory manufacturing and export industry for 20 years. We have loyal relationships with steel enterprises in many countries such as Iran, Ethiopia, Ukraine, etc. We are also supplying refractory materials to more than 20 domestic famous steel enterprises for original equipment purposesuch as Yunnan Desheng, Ji'nan Steel Group, etc.

We are in the position to supply refractory material in full ranges as follows.

1. Basic Refractory-Magnesite Refractory Materials
2. Neutral Refractory-Alumina Carbon Refractory Materials
3. Acid Refractory

According to the shape, our factory produces unshaped refractories and fixed refractories:unshaped refractories we have Ladle filler sand , Refractory mud and refractory castables. Fixed refractories we mainly produce Slide Gate Plate-Nozzle Brock (Type A/B/C).

Our factory has a mature technology team of more than 30 staff, and with more than 100 workers. We can design various products according to customers' requirements in the production of special types of slide gate. We challenged lots of problems and won several national patents.
