Stainless steel pipe fittings billet product quality advantages embodied in addition to the head and tail section rate without grinding the outer surface of the billet has reached more than 70% of the total exterior grinding yield reached 99.15% required to achieve this goal of molten steel refining, achieve lower oxygen and sulfur content, improve metallurgical large and tundish, the precise control of temperature of molten steel, oxidation-free pouring, to further reduce the inclusion content.

Stainless steel pipe fittings billet process steps are as follows:

1. do mold fluxes vibration technology and match depending on the steel, this can increase the yield of 10%, energy and shorten the production cycle in order to improve the yield of molten steel.

2. To adopt casting stainless steel pipe fittings, thus improving the overall finished product rate, and refining and cooperates significantly improve production efficiency, also omitted blooming process, saving a lot of energy.

3. Stainless steel pipe fittings casting and refining furnaces are generally supporting the chemical composition and temperature of the molten steel, there are strict requirements; in order to prevent secondary oxidation of molten steel, continuous casting production process requires no oxidation protection pouring; for ladle, tundish, sliding gate, submerged nozzle and other refractories demanding.

4. To ensure the slab surface quality, select the appropriate maintenance slag; casting process due to vibration of the mold oscillation marks on the surface of the slab to be controlled; ferritic stainless steel pipe fittings must be used when casting electromagnetic stirring.

5. After argon station crane to fine-tune the temperature of molten steel ladle turret wait casting.

6. After casting molten steel, stainless steel and carbon steel pipe fittings generally use the same vertical, angled or curved vertical caster. After refining molten steel into the ladle turret will be pouring through the ladle to tundish injection above the entrance, and then through a long nozzle molten steel into the middle of the pack. Tundish molten steel after immersion nozzle into the mold and condensation forming and continuous down.

Solidification of the slab surface after two cold leg continued rapid cooling to the heart of a solid billet flame length after cutting, to which the entire tube of stainless steel billet process is complete.
