Technical Key Points
Molten steel tapping temperature be controlled between 1640 ℃ -1650 ℃, if temperature is too high, it’s easy to adsorb oxidize in the air; After tapping, slag repeatedly, then sedate for 3-5 minutes for slagging and degassing to purify molten steel. for stainless steel casting, casting temperature should be strictly controlled at 1580℃ -1590℃, thin-walled ultra-low carbon stainless steel pump body, pouring temperature can be controlled at 1590℃ -1610℃; whole processes before pouring, cover agent should be applied to prevent the molten steel surface exposed to the air, resulting in oxidative and inhalation, which will seriously affecting the quality of molten steel.
Ø We are a innovation-driven company, we have five patents and another 13 patents will be expected to get in short months.
Ø We will develop new materials when necessary.
Ø Advantage technology in composition control, especially super low carton steel, stainless steel and duplex stainless steel.
Ø We cast very good surface of thin-wall castings, sand casting is usually not easy to control, but we adopted the appropriate process, can ensure smooth surface, no defects.
Ø Crack is the fatal defect of pressure vessel. We guarantee that the pump and valve castings have no crack inside and outside, and have good withstand voltage performance.
1.What kinds of physical and chemical testing you can provide?
A: The physical and chemical testing we provide include:
Ø Chemical composition testing.
Ø Physical property testing: hardness test, Tensile performance testing, room temperature impact testing, low temperature impact test.
Ø NDT: PT, MT, UT &RT.
Ø Metallographic testing.
2.Can you list the smelting equipment of your company?
A: We have 3 models of medium-frequency induction furnaces: 0.5 tons, 2 tons and 3 tons.
3.Can you guarantee the traceability of your products?
A: Regular products: On-site inspection record and FG Test report will be kept more than 3 years.
Important products: On-site inspection record and FG Test report will be kept more than 5 years, applying processing card system, and make sure one card for each piece, thus to keep each piece of products are traceable.
