We are specialist in making hydraulic turbine assort equipment ,especially the wicket gate ,we take advantage of electroslag technology to manufacture it with prime quality and long service life.
The composition of castings that forged by ESR electroslag forging technology were pure and dense, and scarcely restrict to the shape of the casting. The mould can be used repeatedly; no pollutant discharge after disposing the smoke and dust, so there is no harm to the environment.
Advantages of Electroslag Casting Technology:
1.Nonmetallic inclusion reduce more than a half, and inclusion spread balance;
2.Harmful element sulphur decreases about a half;
3.Each term of machine performance is homogeneity. Prevent layered tear;
4.Impact toughness enhanced;
5.Breakage toughness KIC enhanced;
6.Improve anti-fatigue ability ,and with high resistance to crack and resistance to crack propagation ability;
7.Material density improved obviously, improve anti-cavitation ability, extend the service life, ensure the safety;
8.Ultrasonic testing can satisfy the international standard, the European Union CCH70-3and the United States casting association standard ASTM A609
