PMD High Performance Zirconia Slide Gate Plate Insert in the taphole slag-stopping System of Converter

Product's Features:

Comparing the common type of the zirconia slide gate plate insert, our PMD Higher Performance Zirconia slide gate plate Insert has the longer sliding time continuously than the normal type. Based on the different types of smelting steel, the sliding times they are working are different.

From our longer 5 years' mass quantity using in the main steel plants in China Mainland, such as Baowu Steel, Xiangtan Steel, etc., and the smelting steel type is the normal constructural steel type, the sliding time has reached 18-25 sliding times continuously.

Production Process

Our zirconia Insert is made of the high purity of e-fuzed zirconia grain and powder, stabilizer, bonding agent, through the world advanced full automatic system fully mixing, drying, inspecting, pressing, inspecting, sintering, Inspecting,Polishing Inspecting, etc. series complex process, then packed into the fumigation wooden box with the client's information printed well, deliver to the china mainland and oversea from our factory.

The Bonding way is curving the zirconia slide gate plate into the alumina-c or magnesia-c, etc. various materials body by the refractory mortar.

E-Fuzed Zirconia Material Performance:

The stable zirconia of industrial refractories is mostly prepared by electromelting method. The stable zirconia can be prepared by adding carbon and stabilizer calcium oxide to the zircon electrofusion process. While removing silicon, the solid solution is formed by the interaction of zirconia and calcium oxide. The stable zirconia can be prepared by grinding and granulating. Partially stabilized zirconia has high strength and thermal shock resistance, and is widely used in refractories.

Now for the embedded zirconia insert for the slide gate plate in converter, we are usually taking the Magnesia, Carbon, Yittra, etc. as the main stablizer. As its chemical property is very stable under the very high temperature state, and our PMD Zirconia Slide Gate Plate has higher resisting the erosion and crushing of the steel liquid and slag , excellent thermal shock stability, increasing the working life of the slide gate plate etc.
